9 1 Overview What is RMON This chapter describes SMON, Avaya Inc. s switched network monitoring system. This chapter includes the following sections: What is RMON - A brief description of the RMON standard. What is SMON - A general description of SMON switch monitoring technology. Overview of SMON - An introduction to SMON in the network. SMON Tools - An introduction to the types of tools available in SMON. RMON is the internationally recognized and approved standard for detailed analysis of shared Ethernet and Token Ring media. It ensures consistency in the monitoring and display of statistics between different vendors. RMON s advanced remote networking capabilities provide the tools needed to monitor and analyze the behavior of segments on a network. In conjunction with an RMON agent, RMON gathers details and logical information about network status, performance, and users running applications on the network. An RMON agent is a probe that collects information about segments, hosts, and traffic, and sends it to a management station. The network administrator uses software tools to view the information collected by the RMON agent on the management station. RMON has two levels: RMON I analyzes the MAC layer (Layer 2 in the OSI seven-layer model). RMON II analyzes the upper layers (Layers 3 and above). Avaya M770 and M-MLS SMON User Guide 1

10 Chapter 1 What is SMON RMON is an industry standard that Avaya Inc. and other companies have adopted in their network management applications. SMON takes the RMON standard and extends it to the switching environment. Switch Monitoring SMON is an extension of the RMON standard. SMON adds to the monitoring capabilities of RMON in the following ways: It provides additional tools and features for monitoring in the switch environment. It provides a global view of traffic flow in a network with multiple switches. SMON extends both RMON I for the MAC layer, and RMON II for the network layer and above. SMON monitoring collects and displays data in real-time. Using SMON monitoring, you can get: A global view of traffic for all switches on the network. An overall view of traffic passing through a specific switch. Detailed data about the hosts transmitting packets or cells through a switch. An analysis of traffic passing through each port connected to a switch. A view of traffic between various hosts connected to a switch. Effective switch management requires a comprehensive monitoring mechanism. RMON monitoring is not sufficient for switches. RMON probes can only be used to monitor and analyze a single segment. When you deploy a switch in the network, there are additional components in the network that can not be monitored using RMON, such as switch ports, VLAN, and statistics for all ports. SMON meets this challenge by extending RMON to the switched network. The SMON extensions of RMON allow the network administrator to analyze the switched network and all of its components. 2 Avaya M770 and M-MLS SMON User Guide

11 Overview Enterprise Monitoring Switches are often used in networks with a complex topology. Switches are typically deployed at the center of an enterprise network between clients and servers, or in backbones to provide high bandwidth and secure connectivity. SMON extends RMON to provide global monitoring for complex networks. Enterprise SMON tools provide a network-wide view of all switched devices in the network. They enable you to monitor the entire network in a single window. SMON Management Applications The management applications provided by the SMON extension of RMON include SMON I tools on the MAC layer, and AnyLayer SMON tools on the network layer and above. The SMON I tools extend RMON I to provide switch monitoring and global network monitoring on the MAC layer. These tools include: Enterprise Switch Statistics Enterprise Port Statistics Enterprise History Switch Statistics Switch-wide Quality of Service (QoS) indication (provided as part of Switch Statistics) VLAN Statistics Port Statistics Ethernet Segment Statistics Host Statistics Host Matrix Statistics Port History The AnyLayer SMON tools extend RMON II to provide switch monitoring on the network layer and above. These tools include: Protocol Directory Protocol Distribution Avaya M770 and M-MLS SMON User Guide 3

12 Chapter 1 Overview of SMON Network Layer Host Statistics over IP Network Layer Subnet Statistics over IP Network Layer Network Statistics over IPX SMON Devices Avaya MultiService SMON Manager in conjunction with Avaya Device SMON applications form an RMON-compliant network management suite that implements the SMON extensions to RMON. SMON works with the other components of the Avaya MultiService Network Manager to provide a full spectrum of in-depth monitoring of switch traffic and network performance. SMON consists of a software console application on a workstation and remote monitoring probes in network devices that support SMON. The SMON console communicates constantly with the SMON devices on your network. The console uses the SNMP protocol to gather information from the devices. SMON applications provide you with a suite of powerful graphic display tools to view this information. SMON applications give you detailed analysis of the traffic flow on your switched network, from a global view down to a specific host, and from total MAC layer traffic down to a specific application protocol - all in real-time. SMON provides monitoring capabilities for network devices that support the SMON extensions of the RMON standard. For Avaya M770 and M-MLS Devices, SMON monitoring capabilities can be activated by purchasing an SMON license from Avaya Inc., Bell Labs Innovations. Avaya M770 M-MLS Devices also support the AnyLayer SMON extensions of RMON II. 4 Avaya M770 and M-MLS SMON User Guide

13 Overview Top-Down Monitoring SMON provides multi-tiered monitoring capabilities, both for the MAC layer (SMON I) and for upper layers (AnyLayer SMON). Multi-tiered monitoring enables you to use powerful top-down network monitoring techniques. Top-down monitoring begins when you notice particular traffic flow patterns in a global view of your network. You then progessively focus in until you find the specific source or sources of the traffic. Using this method, the amount of information you need to assess is kept to a minimum. Top-down monitoring is robust enough to keep you in control of even the most complex and sophisticated networks. Top-Down Monitoring for the MAC Layer The top tier for SMON top-down monitoring at the MAC level (SMON I) is Enterprise Switch Statistics. The Enterprise Switch Statistics tool shows summary traffic statistics for all switches in your network. The next two tiers provide a general look at the traffic passing through a specific switch. In this way, you can view at a glance whether the switch is functioning efficiently and effectively. These tiers provide answers to questions such as: Is there more traffic than usual passing through this switch? Are there more error packets than usual? How much traffic is passing through the VLANs? Do the VLANs have equal loads? Avaya M770 and M-MLS SMON User Guide 5

14 Chapter 1 The lower monitoring tiers provide more focused views of the traffic on the device. They allow you to zero in on a specific host or port on a switch. You can then pinpoint the exact source of the traffic discovered in the upper tiers. Figure 1-1. Top-Down Monitoring for the MAC Layer Top-Down Monitoring for the Upper Layers SMON provides a series of AnyLayer SMON tools for implementing topdown monitoring techniques at the network layer and above. Top-down monitoring on upper layers allows you to view aspects of your network that extend beyond the router, or that apply to a specific application protocol. The upper tier of SMON top-down monitoring for upper layers is Protocol Distribution. The Protocol Distribution tool gives a general view of traffic through a switch, organized by protocol. Some of the types of questions Protocol Distribution may provide answers to are: What proportion of the traffic consists of IP or IPX maintenance protocols, such as ARP, RIP, or SAP? Is there an unusual amount of traffic for a specific type of application protocol, such as , name service, or HTTP? 6 Avaya M770 and M-MLS SMON User Guide

15 Overview Is there an unusual amount of ICMP traffic that may be caused by flood pinging? The lower tiers then allow you to locate the IPX network, IP subnet, or specific IP host that is the source of the traffic discovered using Protocol Distribution. Figure 1-2. Top-Down Monitoring for Upper Layers Avaya M770 and M-MLS SMON User Guide 7

16 Chapter 1 SMON Tools The SMON tools are divided into the following: Enterprise SMON Tools - The Enterprise SMON tools and how they function. Device SMON Tools - The Device SMON tools and how they function. AnyLayer SMON Tools - The AnyLayer SMON tools and how they function. Figure 1-3. SMONMaster Tools Enterprise SMON Tools Enterprise SMON tools provide global monitoring capabilities for multiple SMON devices on a network. For information on Enterprise SMON tools, refer to Avaya MultiService SMON Manager User Guide. 8 Avaya M770 and M-MLS SMON User Guide

17 Overview Device SMON Tools Device SMON tools monitor specific devices. For Avaya M770 Devices there is an SMON control panel that provides access to the specific SMON tools that you can use for the device. * Note: For information on SMON for Avaya P130 Devices, refer to Avaya P130 SMON User Guide. For information on SMON for Avaya P330 Devices, refer to Avaya P330 SMON User Guide. For information on SMON for Avaya P580/P882 Devices, refer to Avaya P550/P880 SMON User Guide. Device SMON includes MAC layer monitoring tools (SMON I) for Avaya M770 Devices. Figure 1-4. Avaya M770 SMON Control Panel The Device SMON tools for SMON devices include: Switch Statistics - Detailed information on traffic passing through the switch fabric. VLAN Statistics - Detailed information on switch traffic associated with a VLAN. Port Statistics - Detailed information on port traffic to help determine the precise cause of a problem. Device SMON tools operate on a single switch at a time. For Avaya M770 Devices, you can select either the right DomainX or the left DomainX from the Device SMON control panel (refer to Figure 1-4). Avaya M770 and M-MLS SMON User Guide 9

18 Chapter 1 Switch Statistics Overview The Avaya M770 SMON Switch Statistics tool provides details of the traffic passing through the switch fabric and allows you to detect problems on the switch. Once a problem has been detected, you can use Port Statistics to determine more precisely the cause of the problem. The display includes two sections: Pie charts or meters showing traffic breakdown. A browser that describes the characteristics of the traffic passing through the switch. For Avaya M770 Devices in which two switches (Left DomainX and Right DomainX) can exist in a single device, traffic passing through a selected DomainX is analyzed. You can use the Switch Statistics tool for the following purposes: Gaining an overall view of the switched traffic over a specific time period. This can help in discovering problems and analyzing traffic trends. Discovering whether or not the switch is being utilized efficiently. Monitoring the load distribution among VLANs. Detecting a large number of broadcast messages sent. This indicates there may be a problem with a station on the network. Treating any variable with abnormal behavior as an issue that should be investigated further using other SMON tools. In general, the Switch Statistics tool can help you spot problems that only become apparent from a high-level view over time. By periodically viewing Switch Statistics, you can detect normal and abnormal behavior of the specific switch configuration. SMON collects and displays all information in real-time. In addition, information collected during a session can be saved for later viewing and comparison. VLAN Statistics Overview The VLAN Statistics tool measures the switched traffic travelling through VLANs on the selected switch. A VLAN consists of stations connected logically rather than physically. A VLAN can be used, for example, to distribute network resources by department, even if the department s stations are not all located in the same area. Therefore, a VLAN can incorporate stations from different devices. 10 Avaya M770 and M-MLS SMON User Guide

19 Overview By comparing the load of each VLAN you can discover which VLANs are: Utilizing their full capacity. Under capacity. Over-extended and probably causing a degradation in performance to the users. VLAN Statistics represents the information as a horizontal bar chart. Using this tool in conjunction with Port Statistics and Switch Statistics makes it straightforward to discover the cause of a problem. For example, using VLAN Statistics you may discover that there are too many broadcast errors on a specific VLAN. You could then use Port Statistics to help indicate from which port the problem originates. Port Analysis Tools There are several SMON tools that allow you to see the rates of traffic passing through individual ports on a switch: Port Statistics Ethernet Segment Statistics Port TopN For each port, SMON summarizes the traffic, such as packets into the switch and packets from the switch. You can sort by port name or by any of the packet types. You can see, for example, the ports generating the most errors. Port TopN produces a report for the most active ports on the switch. If you notice that a particular port displays a disproportionate amount of errors, this may suggest that a device connected to the port is responsible. If the attached port supports a Fast Ethernet connection, only a few hosts will be attached to this port, so the responsible host can easily be detected. In addition, you can apply filters in order to examine: Most active ports - To discover which ports are generating a high traffic load. Specific ports - To view statistics on these specified ports. These may be a group of ports whose behavior you want to analyze. You select the most active ports by using a rate base. SMON measures the rate base for all the ports to find the most active ports and then displays these ports and their statistics. This process is called Port TopN. Avaya M770 and M-MLS SMON User Guide 11

20 Chapter 1 AnyLayer SMON Tools Using the Port Statistics tool in conjunction with VLAN Statistics and Switch Statistics makes it straightforward to discover the cause of a problem. For example, using Switch Statistics you may discover that there are too many errors on a specific switch. You could then use Port Statistics to help indicate the port from which the problem originates. The following are sample uses of the Ethernet Segment Statistics tool: Gaining an overall view of the port over time. This can help in discovering problems and analyzing traffic trends. Determining if the utilization percentage is unusually high or low, enabling you to reconfigure your network accordingly for a more equal load. Detecting a large number of broadcast messages sent, indicating that there could be a problem with a station connected to the port. AnyLayer SMON tools include upper layer monitoring tools for the Avaya M-MLS. For information on AnyLayer SMON tools for Avaya P333R and X330WAN Devices, refer to the Avaya P330 SMON User Guide. Figure 1-5. AnyLayer SMON Control Panel for Avaya M-MLS 12 Avaya M770 and M-MLS SMON User Guide

21 Overview The AnyLayer SMON tools for Avaya M-MLS Devices include: Protocol Directory - Displays and updates the list of protocols monitored by the AnyLayer SMON device. Protocol Distribution - Provides detailed information on protocol traffic passing through the switch. Network Layer Subnet Statistics (IP & IPX) - Provides detailed information on traffic associated with an IP subnet or IPX network. Network Layer Host Statistics (IP) - Provides detailed information on traffic associated with a specific IP host. When the Device SMON control panel is closed, all associated Device SMON applications are also closed. Protocol Directory The Protocol Directory tool enables you to view and configure the protocols being monitored by a router module. Protocol Directory shows a list of the protocols that the router module is currently monitoring, and a list of other protocols that are available to be monitored. You can add or remove protocols from the list of protocols that the device is monitoring, and upload your changes to the device. Based on the protocols chosen in Protocol Directory, you can monitor protocol traffic through the AnyLayer SMON device using Protocol Distribution. Protocol Distribution Protocol Distribution provides you with details about the protocols passing through a router module. Protocol Distribution shows the balance between IP and IPX traffic in the device, and tracks the distribution of traffic through the device among various network and application layer protocols. Protocol Distribution collects all information in real-time, and displays it in a variety of powerful and easy to use graphic formats. Protocol Distribution provides information graphically in two sections: The upper part of the window includes a bar graph and two pie charts which show information based on the network layer. The bar graph shows IP/IPX distribution, the first pie chart shows distribution of IP traffic among popular protocols, and the second pie chart shows distribution of IPX traffic. Avaya M770 and M-MLS SMON User Guide 13

22 Chapter 1 The lower part of the window is a traffic graph that displays line graphs of traffic rates for various application layer protocols over IP. You can specify which protocols to display from among those that the router module is monitoring. Protocol monitoring settings in an AnyLayer SMON and configured using the Protocol Directory tool (refer to Chapter 8, Protocol Directory). Protocol Distribution stores all data recently collected from the device. This allows you to use the bar graph, pie charts, and traffic graph to study the behavior of your network over a period of time. Protocol Distribution also allows you to save collected information from a session for later viewing and comparison. Protocol Distribution gives you an overall view of the traffic passing through the device over time. You can learn what is normal and abnormal behavior for your specific network by viewing the Protocol Distribution graphs and studying the relationships between them. This can help you analyze traffic trends on your network, and discover problems as they occur. In general, the Protocol Distribution tool can help you see things that only become apparent over time from a highlevel view. Network Layer Subnet Statistics (IP & IPX) Network Layer Subnet Statistics provides you with detailed information on each IP subnet or IPX network passing traffic through a router module. It summarizes the traffic for each subnet in average or cumulative packets, depending on user selection. Network Layer Subnet Statistics provides the information you need to locate various kinds of subnets that exist in the network. It is useful for discovering which subnets are generating high traffic loads. Using Network Layer Subnet Statistics, together with TopN and filters, you can get an in-depth analysis of network traffic to help locate problems on the network. * Note: The Network Layer Subnet Statistics Window for IPX shows data relating to IPX networks rather than IP subnets. Network Layer Host Statistics (IP) Network Layer Host Statistics provides you with detailed information on each host passing IP traffic from one subnet to another through a router module. You can select whether to summarize the traffic for each host in average or cumulative packets. A host is any IP machine connected to a switch port that can send and receive packets to or from other IP machines. A host is normally a workstation, management console, or server. 14 Avaya M770 and M-MLS SMON User Guide

23 Overview SMON gathers data for Network Layer Host Statistics by monitoring the traffic going through the Avaya M-MLS switch. Therefore, SMON does not monitor any traffic that does not pass through the switch, such as traffic between hosts on the same subnet. The following diagram displays a scenario where two stations may communicate with or without transmitting traffic through the switch. Figure 1-6. Host Traffic on the Network If host A talks with host C, the traffic passes through the switch as both hosts reside on different subnets. SMON monitors the packets between the two hosts. However, when host A communicates with host B, they are both on the same subnet and traffic does not pass through the switch. SMON does not monitor the traffic between these two hosts. Therefore, be aware that although SMON monitors ALL the traffic transmitted through the multi-layer switch, it does not monitor ALL the traffic on the network. SMON represents the information as a horizontal bar chart. After discovering that a problem exists using the Protocol Distribution and Network Layer Subnet Statistics monitoring tools, you can use Network Layer Host Statistics, together with TopN and filters, to investigate the problem further to help locate the cause. Network Layer Host Statistics provides the information you need to locate various kinds of hosts that consume too great a share of switch resources, such as busy servers that may become bottlenecks in the network.

24 2 Using SMON Tools This chapter explains how to access SMON tools after you have installed Avaya M770 and M-MLS SMON, and how to manipulate and customize the SMON display for maximum effectiveness. It includes the following sections: Customizing the Display Focusing on a Point Saving and Opening a Session Generating Reports Configuring a Printer for UNIX Using the Toolbar The Status Bar Mouse Actions Viewing Options Customizing the Display SMON graphs can easily be customized to provide varying graphical perspectives or zoom. For some charts, the following mouse and keyboard combinations allow you to change the display: Table 2-1. Display Customization Methods Action Rotating the Chart Zooming Method Hold down the left and right mouse buttons (or the center mouse button on some systems) and move the cursor. This rotates the 3D perspective view of the chart. Hold down the CTRL key and left mouse button and select the desired zoom area with the mouse. Avaya M770 and M-MLS SMON User Guide 16

25 Using SMON Tools Table 2-1. Display Customization Methods (Continued) Action Repositioning the Chart Scaling the Chart Method Hold down the SHIFT key and both mouse buttons (or the center mouse button on some systems) and move the cursor. This repositions the chart within the window. Hold down the CTRL key and both mouse buttons (or the center mouse button on some systems). This option enlarges and reduces the chart on the screen. Focusing on a Point * Note: You can undo any display changes made (except for Chart 3D Perspective changes) and return to the default settings by moving the mouse pointer over the graph and typing: r. In some applications where you have traffic graphs (for example, Switch Statistics, Segment Statistics, and Protocol Distribution), you can focus the display on a single point in time within the current session. When you focus on a point, all the graphs in the application window display data for the poll closest to that point. Focusing on a point in time freezes the application s display. To focus on a point: 1. Scroll the traffic graph until the point is visible. 2. Double-click on the point in the traffic graph. When you focus on a point, the appearance of the application display changes in the following ways: The point you selected moves to the middle of the display area on the traffic graph. A vertical line appears on the traffic graph at that point. The traffic graph zooms in. The bar and pie charts in the top portion of the application window show data for that time. The numbers displayed in the legend to the right of the traffic graph show data for that time. The status bar indicates that the display is frozen and focused. Avaya M770 and M-MLS SMON User Guide 17

26 Chapter 2 To stop focusing on a point: Click. Or Select Display > Freeze/Unfreeze Display. Or Right-click on the traffic graph and select Stop Focus. Or Scroll the traffic graph. (Only this method is available during a saved session.) The graph charts various types of traffic over time. Each type of traffic is represented by a line of a different color. Using the mouse, you can view traffic statistics, zoom in or out of the graph, and scroll within the graph to view parts of the graph which are currently hidden. When changing the view on the graph, the graph freezes. To unfreeze the graph and restore the display to the default display, click on the graph. Saving and Opening a Session Some of the applications allow you to save collected information from a session in a session file. You can later open the saved session for viewing and comparison. To save the current session to a session file: 1. Click. Or Select File > Save Session. 2. Enter a file name (the file extension is provided by the individual tools, e.g.,.sts for Switch Statistics). To open and view a saved session: Click. Or Select File > Open Session. 18 Avaya M770 and M-MLS SMON User Guide

27 Using SMON Tools Generating Reports * Note: When you open a session, the application closes the session that you were previously viewing. Consider saving the current session before opening another one. The application does not poll an SMON device for data when you are viewing a saved session. SMON allows you to produce two types of reports: Report Now - You can save the collected statistics of the current session to a text file that can be imported into word processors and spreadsheets such as Microsoft Word and Excel respectively. The data saved includes only the statistics collected during the last polling interval, and is stored in ASCII format. Auto Report - You can choose whether reports are automatically generated and where they are stored on disk in ASCII format. The first report is generated immediately. Subsequent reports are generated according to the polling interval. Reports continue to be generated until you specify that you wish to discontinue the report, or you close the application for which you are running the Auto Report. Configuring a Printer for UNIX Using the Toolbar Some SMON tools allow you to print data directly to a printer. On Unix platforms, configuring and installing printers in SMON is identical to configuring and installing printers in Bristol Hyperhelp. Refer to Configuring a Printer and Installing a Printer in Bristol Hyperhelp for more information. The toolbar that appears in and Avaya M770 and M-MLS SMON windows provides shortcuts to important functions.

39 Switch Statistics Switch Statistics Window * Note: The exact appearance of the Switch Statistics window will vary depending on the device being monitored. Switch Statistics displays information using two types of graphs: Pie charts that show Network Usage, Packet Destination, and Priority Usage. A browser section that contains line graphs describing the characteristics of the traffic traveling through the switch. The title of the Switch Statistics window displays the Device Type and the Device IP Address, DomainX, and indicates if the session is a live or saved session. The bar graph and pie charts show data for the time furthest to the right currently visible on the traffic graph, unless you have focused the display on a point. For more information, refer to Traffic Graph in the Switch Statistics Window on page 32 and Focusing on a Point on page 17. You can use the bar graphs and pie charts to view data from an earlier point in time by double-clicking on the traffic graph, or by scrolling the traffic graph. For more information, refer to Focusing on a Point on page 17. Switch Statistics allow you to save collected information from a session in a session file. You can open the saved session in Switch Statistics for viewing and comparison. For more information, refer to Saving and Opening a Session on page 18. For more information about modifying the display, and the available toolbar, status bar, and mouse movement options, refer to Chapter 2, Using SMON Tools. Avaya M770 and M-MLS SMON User Guide 31

40 Chapter 4 Pie Charts in the Switch Statistics Window The pie charts at the top of the window display the following information: Table 4-1. Pie Chart Variables in the Switch Statistics Window Variable Network Usage Packet Destination Priority Usage Description Displays the proportion of good packets in relation to error packets traveling through the switch, as a percentage. If the amount of error packets begins increasing or takes up a significant part of the chart, this indicates there may be a problem. Displays the distribution of packets into unicast, multicast, and broadcast. On most networks the unicast packets should constitute the vast majority of the pie graph. If broadcast or multicast (non-unicast) packets begin to increase, this indicates there may be a problem. Displays the distribution of packets according to their priority. If one of these parameters starts producing abnormal figures, this indicates there may be a problem. SMON updates these charts in real-time according to the specified sampling interval. By viewing the relationships among these three variables, you can learn a lot about the general behavior of the switch. * Note: If contact with the agent is lost, then the graphs will display the last data received until communications are restored. If the display is gray, there is no traffic on the switch. Traffic Graph in the Switch Statistics Window The lower portion of the Switch Statistics window is a traffic graph. The traffic graph displays selected variables as a line graph, in real-time. To select the color coded variables you want graphed, use the check boxes to the right of the traffic graph. To select from among other variables that are available to be graphed, select Configuration > Counters Setup. SMON continuously monitors statistics for all available Switch Statistics traffic variables, even those that are not currently selected. 32 Avaya M770 and M-MLS SMON User Guide

41 Switch Statistics The X axis of the graph represents time. The scale on the X axis changes as you use the Zoom option to view the data for different time periods. The units of the Y axis for all variables are packets, octets, or cells per second. The scale on the Y axis depends on the maximum value among all of the variables. If the spread of values is wide, the graphs of variables with small values may not be visible. In this case, use the logarithmic traffic display to produce better results (refer to Appendix A, Using the Graph Display Dialog Box). Comparing the traffic graphs to the pie graphs can often point you in the right direction for locating a problem. For example, the Packet Destination pie graph may show an abnormal amount of broadcast packets while the bandwidth usage shown in the traffic graph has increased significantly. This may suggest that one of the stations attached to the switch is generating the broadcast packets. By using VLAN Statistics, you can locate the VLAN where the problem originates. By using Port Statistics you can locate the port to which the suspected station is attached. To zoom in to a specific bucket, double-click on the traffic graph. For more information, refer to Focusing on a Point on page 17. * Note: All counters are in packets per second, octets per second, or cells per second, as an average for the last interval, except counters that measure bandwidth, which are in kilobits per second (Kbps), and utilization, which is a percentage. To change the variables displayed in the Traffic Graph, refer to Using the Counters Setup Dialog Box on page 80. Table 4-2.

50 Chapter 7 Pie Charts in Ethernet Segment Statistics The pie charts at the top of the window display the following information: Table 7-1. Pie Chart Variables in Ethernet Segment Statistics Variable Network Usage Packet Destination Packet Length Description Displays the proportion of good and bad packets. The bad transmissions include: CRC alignment errors, packet fragments, jabbers and oversized packets. If the number of packets other than good packets starts increasing, or takes up a significant part of the chart, this indicates that there may be a problem. Displays the distribution of packets into unicast, multicast, and broadcast packets. On most networks, the unicast packets should constitute the vast majority of the pie graph. If broadcast or multicast packets begin to increase their share of the graph, this indicates that there may be a problem. This pie chart is only displayed for ports that can operate as Fast Ethernet ports. It is displayed regardless of the actual operating port speed of the port. The pie chart breaks down packet length from 64 bytes to 1518 bytes. It indicates the type of packets sent on the network. If the pie chart shows abnormal percentages of packets of varying lengths, it could indicate that there is a problem on the network. SMON updates these charts in real-time according to the specified sampling interval. By viewing the relationships among these three variables, you can learn a lot about the behavior of the selected port. * Note: If contact with the agent is lost, the graphs display the last data received from the agent until contact is restored. If the display is gray, then there is no traffic on the segment connected to the port. 42 Avaya M770 and M-MLS SMON User Guide

51 Ethernet Segment Statistics Traffic Graph in Ethernet Segment Statistics The lower portion of the window is a traffic graph. The traffic graph displays selected variables as a line graph, in real-time. Data is generally displayed as packets or octets per second for the sampling interval. To select the variables you want graphed, check the checkboxes to the right of the traffic graph. * Note: Even if a variable is not selected in the traffic graph, the system continues to monitor its statistics. To zoom in to a specific time period, double-click in the traffic graph. To specify additional traffic variables, select Configuration > Counters Setup (refer to Using the Counters Setup Dialog Box on page 80). A legend to the right of the traffic graph indicates the colors used for each selected variable. The information in the Ethernet Segment Statistics window is provided in the following manner: The traffic graph title displays the following information about the port: The operational bandwidth (speed) of the port. For a 10Mbps port, the title always displays 10M. For a 10/100Mbps port, the title displays the port s configuration bandwidth, i.e., 10M or 100M. The mode of the port - Full Duplex or Half Duplex. Full Duplex mode is indicated by (FD) after the Bandwidth indication. If (FD) is not indicated, the mode is Half Duplex. The name of this port s device or module, and the device/module and port numbers. Whether the data collection includes local segment traffic. The X axis of the graph represents time. This scale changes as you use the Zoom option to view the data for different time periods. The units of the Y axis for all variables are packets or octets per second. The scale depends on the maximum value among all of the variables. If the spread of values is wide, the graphs of variables with small values may not be visible. The logarithmic traffic graph display may produce better results in that case (refer to Using the Display Configuration Dialog Box on page 66). Avaya M770 and M-MLS SMON User Guide 43

52 Chapter 7 Comparing the traffic graphs to the pie graphs can often point you in the right direction for locating a problem. For example, the Network Usage pie graph may show an abnormal number of oversized packets, while the utilization rate shown in the traffic graph has increased significantly. This indicates that one of the stations attached to the port is generating the oversized packets. The table below contains all the variables that may appear in the traffic graph and a brief description of each one. Variables available only for 100 Mbps ports, or only for 10 Mbps ports, are marked accordingly. Table 7-2. Traffic Variables in Ethernet Segment Statistics Window Variable Broadcast Octets (10 Mbps ports only) Broadcast Packets Collision Events CRC Alignment Errors Error Octets Error Packets Fragments Good Octets Good Packets Jabbers Late Collision Events Description Good Ethernet octets per second counted on the port s segment, sent to broadcast destinations.

The TCP/UDP port number indicates how to apply an application layer protocol to the data at the receiving end. For example, port 25 is associated with the SMTP application protocol, and port 23 is associated with the Telnet application protocol. A single application protocol may use several different TCP/UDP port numbers for various kinds of communication functions it performs. Avaya M770 and M-MLS SMON User Guide 49

58 Chapter 8 There are three ranges of TCP/UDP port numbers: Using Protocol Directory TCP/UDP ports Well Known Port Numbers. Well Known Port Numbers represent basic network services that are widely available using standard TCP/UDP port numbers. Well Known Port Numbers are assigned by the IANA (Internet Assigned Numbers Authority). On many platforms, the ways in which these TCP/UDP ports can be used are restricted by the system. TCP/UDP ports Registered Port Numbers. Registered Port Numbers represent specific network services that have been registered by the IANA at the request of a vendor or organization. TCP/UDP ports Private Port Numbers. Private Port Numbers are available for unrestricted use by applications. The same Private Port Number might be used for different purposes by different applications. To access the Protocol Directory window, click in the Device SMON control panel. The Protocol Directory window opens. * Note: Close all other AnyLayer SMON tool windows before opening Protocol Directory.
