6 Introduction SolarWinds VoIP and Network Quality Manager offers an easy-to-use, scalable IP SLA network monitoring solution that can integrate seamlessly with other SolarWinds products on the Orion Platform. Why install SolarWinds VoIP and Network Quality Manager Internet Protocol Service Level Agreement (IP SLA) technology offers a cost-effective and efficient response to the needs of enterprises of all sizes. As a network manager, you face more than the simple question of whether your network is up or down. You need to know specific quality of service measurements for your network. SolarWinds VoIP and Network Quality Manager gives you the tools to quickly test the fitness of your current network, and then determine and track quality of service on your network over time. SolarWinds VoIP and Network Quality Manager collects IP SLA-specific data and provides presentation tools that enable IP SLA network monitoring and real-time status reporting. SolarWinds VoIP and Network Quality Manager can also be used in integration with SolarWinds Network Performance Monitor, leveraging the SolarWinds NPM monitoring options to provide a better overview of your network. How SolarWinds VoIP and Network Quality Manager Works SolarWinds VoIP and Network Quality Manager builds upon the proven technology of the Orion Platform to give you monitoring, alerting, and reporting abilities for your network. After installation and initial configuration, SolarWinds VoIP and Network Quality Manager deploys Cisco IP SLA operations to generate various types of network traffic including DNS requests, DHCP IP allocation, FTP and HTTP requests, TCP connect, ICMP and UDP Echo, and simulated VoIP traffic between devices on your network using the jitter codec you specify. Cisco IP SLAs provide real-time and historical performance statistics that SolarWinds VoIP and Network Quality Manager presents in the readily customizable Orion Web Console. SolarWinds VoIP and Network Quality Manager downloads CDR/CMR data from your Cisco call manager and uses your AXL credentials to pull region information to provide detailed call record information about every call in your network. You can also monitor Avaya Communication and Media Server devices with SolarWinds VoIP and Network Quality Manager. VNQM intercepts the CDR packets sent by the TCP protocol, as well as the RTCP data sent through UDP, and based on these data, it provides information about the call details and the call quality. IP SLA operations SolarWinds VoIP and Network Quality Manager only work with Cisco IOS devices that support the RTT MIB. For more information about the MIBs VNQM uses, see MIBs Maintained by VNQM. 5

7 For VoIP statistics, SolarWinds VoIP and Network Quality Manager uses simulated VoIP traffic, instead of real VoIP traffic. This ensures the continuous collection of performance statistics so you can know the state of your network at any time, regardless of whether the network is actually being used to complete a call. What SolarWinds VoIP and Network Quality Manager Does With SolarWinds VoIP and Network Quality Manager you can monitor and report both real-time and historical performance statistics for your IP SLA-capable network. SolarWinds VoIP and Network Quality Manager offers the following features to help you manage your entire network: Quality of Service (QoS) Monitoring with Cisco IP SLA Operations SolarWinds VoIP and Network Quality Manager uses Cisco IP SLA operations to measure network performance. Specifically, IP SLA operations provide immediate insight into network Quality of Service (QoS), including packet loss, latency, jitter, and mean opinion score (MOS) metrics. SolarWinds VoIP and Network Quality Manager collects IP SLA data and then presents it in the easyto-use Web Console environment. With SolarWinds VoIP and Network Quality Manager and IP SLA operations, you know at a glance exactly how well your network is and has been performing. For more information about Cisco IP SLA operations, see VoIP Phone Troubleshooting SolarWinds VoIP and Network Quality Manager uses Call Detail Records (CDR) and Call Management Records (CMR) data from your call managers to help you identify possible affected calls and patterns of affected calls. CDR/CMR data provides region information per call record in addition to the call source and destination, MOS, latency, packet loss, termination call code, and more. With SolarWinds VoIP and Network Quality Manager, you can drill in to problem areas to start identifying the underlying problems. Custom Charts and Gauges SolarWinds VoIP and Network Quality Manager provides easy-to-read charts and gauges that you can customize to suit your monitoring requirements. You can quickly determine the current status and performance of your network using custom gauges of key IP SLA metrics such as jitter, latency, packet loss, and MOS. With custom charts, you can easily track the historical performance of all the paths on your network. Custom Alerts and Actions SolarWinds VoIP and Network Quality Managerenables you to create custom alerts for your network in the same way you create alerts and actions in SolarWinds Network Performance Monitor. Specifically, you can configure IP SLA-related alerts with a variety of corresponding actions to notify you of events on your network. For more information, see Creating and Managing Alerts. 6

8 Custom Reporting With Orion Report Writer, SolarWinds VoIP and Network Quality Manager provides real-time and historical statistics reporting for the IP SLA-specific network statistics. When you install VNQM, several predefined reports become available within Report Writer. By using custom properties, you can also generate custom reports to specifically communicate the historical condition of your network. For more information about data reporting, see Reports. Gateway Monitoring SolarWinds VoIP and Network Quality Manager provides comprehensive resources that enable you to monitor your VoIP gateways, giving you an overview of individual PRI trunks of your gateways. Call Manager Monitoring Call manager devices are scalable call processing solutions for managing IP-based telecommunications networks. These devices provide VoIP networks with the features and functions of more traditional telephony. SolarWinds VoIP and Network Quality Manager uses the SNMP and ICMP monitoring technology and the AXL API of Cisco to interact with call managers and to persistently track call manager performance. With the addition of SolarWinds VoIP and Network Quality Manager, you immediately know the status of your VoIP network and all of its components at any time. SolarWinds VoIP and Network Quality Manager comes with presets that allow you to monitor Cisco CallManager and CallManager Express, and Avaya Call Manager devices. You can also define custom Management Information Base (MIB) pollers to monitor call managers from other manufacturers. Call managers by other manufacturers are monitored like other nodes and cannot be added as call managers. For more information, consult the following table. TOPIC REFERENCE Custom MIB Pollers Cisco CallManager Supported Devices Adding Cisco CallManager Devices Adding Avaya Call Manager Devices Monitoring CallManager Devices from Other Manufacturers See Monitoring MIBs with Universal Device Pollers. Search for "CallManager" at See Managing Call Managers. See Adding Avaya Call Manager devices to VoIP and Network Quality Manager. See Adding Call Manager devices from other manufacturers. 7

9 Understanding Quality of Service and IP SLAs IP Service Level Agreements (IP SLAs) are a diagnostic method developed by Cisco that generates and analyzes traffic between Cisco IOS devices on your network. By using SolarWinds VoIP and Network Quality Manager to implement IP SLA operations between your network devices, you can acquire real-time and historical statistics that give you accurate Quality of Service (QoS) measurements over designated network paths between a source device and a target device. For a better understanding of individual quality of service and IP SLAs, it is necessary to understand the following concepts: Source A device that creates and inserts IP SLA packets into the network. The source is where all IP SLA operation tests are initiated. Target The ultimate destination of the packets created and sent by the source. Operation The type of test being performed on the network. IP SLA Operations in VNQM The following operations are supported by SolarWinds VoIP and Network Quality Manager. DHCP Dynamic Host Configuration Protocol (DHCP) IP SLA operations measure the response time taken to discover a DHCP server, and then obtain a leased IP address from it. DNS Domain Name Server (DNS) IP SLA operations measure the difference in time from when a DNS request is sent and when the reply is received. FTP File Transfer Protocol (FTP) IP SLA operations measure the response time between a Cisco device and an FTP server to retrieve a file. HTTP Hypertext Transfer Protocol (HTTP) IP SLA operations measure distributed web services response times. ICMP Echo Internet Control Message Protocol (ICMP) Echo IP SLA operations measure round trip time between nodes on the network. 8

10 ICMP Path Echo ICMP Echo IP SLA operations measure round trip time hop-by-hop between nodes on the network. ICMP Path Jitter ICMP Path Jitter IP SLA operations measure WAN quality by testing connection times hop-by-hop between two devices. TCP Connect Transmission Control Protocol (TCP) Connect IP SLA operations measure WAN quality by testing connection times between two devices using a specific port. UDP Echo User Datagram Protocol (UDP) Echo IP SLA operations measure round trip time between nodes on the network. UDP Jitter UDP Jitter IP SLA operations measure WAN quality by testing connection times between two devices using a specific port number. VoIP UDP Jitter Voice over Internet Protocol (VoIP) UDP Jitter IP SLA operations measure call path metrics on the VoIP network. 9

11 Getting started with VoIP and Network Quality Manager SolarWinds VoIP and Network Quality Manager provides a wizard-driven installation process. The installation is powered by the following tools: 1. The VNQM Installation Wizard installs VNQM and launches the installation of the corresponding.net framework requirements. 2. The VNQM Licence Activation Wizard deals with the activation of your license, you can temporarily skip this step. 3. The SolarWinds Configuration Wizard takes care of the basic configuration of VNQM. You can find more installation related details in the following sections. Installation requirements The following requirements are based on a minimum installation of SolarWinds VoIP and Network Quality Manager with SQL Server on a separate database server. To optimize database scalability, SolarWinds recommends that you maintain your SQL Server installation on its own server. If you must host your SQL server on the same server, SolarWinds recommends a quadprocessor, 2.67 GHz, 64-bit CPU and at least 16 GB of RAM.

We do not support more than six million calls per month. If you are installing SolarWinds VoIP and Network Quality Manager with SolarWinds NPM, see NPM Requirements. SolarWinds VoIP and Network Quality Manager licensing SolarWinds VoIP and Network Quality Manager uses four different license types and is licensed on the IP SLA site level, the IP Phone level, and the node level. 11

13 The following license types are available: SLA 5 5 IP SLA sites, 300 IP Phones, and 40 nodes SLA IP SLA sites, 1500 IP Phones, and 200 nodes SLA IP SLA sites, 3000 IP Phones, and 400 nodes SLA X Unlimited IP SLA sites, unlimited IP Phones, and 1000 nodes IP SLA sites Any device that has at least one monitored operation counts toward your IP SLA site count. IP phones Any IP phone connected to your network when the network is polled counts toward your IP phone count. Phones can be registered or unregistered. Registered phones are connected, take precedence over unregistered phones, and count toward your license. Unregistered phones are disconnected and do not count toward your license. If you have more registered IP phones than the number granted to you by your license, only the latest registered phones will be monitored, up to the number of phones granted by your license. Registered and unregistered phones after that number will not be monitored. Nodes Any SNMP-enabled device that you monitor counts toward your node count. Each monitored call manager typically consumes a node license. Each source node counts towards your node count. In a bidirectional setup, each node is both a source and target node, and they both count towards your license. Licensing example If your network uses four IP SLA sites, 45 nodes, and 700 IP Phones, you may decide to purchase the smallest license. The number of IP SLA sites fall within your license count, but the number of nodes and IP Phones do not. When you configure SolarWinds VoIP and Network Quality Manager, you must choose 40 out of your 45 nodes to monitor, including the call managers you want to monitor. SolarWinds VoIP and Network Quality Manager automatically monitors only 300 registered IP Phones at a time of the 700 on your network. Each time your network is polled, a different 300 registered IP Phones may be monitored.

VoIP Infrastructure You can define the devices whose status you want to monitor in the VoIP Infrastructure resource. For more information, see Selecting VoIP infrastructure. Discovering your network SolarWinds VoIP and Network Quality Manager provides the easy-to-use Network Sonar Wizard to direct you in the discovery of devices on your network. Before using the Network Sonar Wizard, consider the following points about network discovery: Discovery does not add devices that are already in your database. Network Sonar recognizes and adds only new network devices. The community strings you provide in the Network Sonar Wizard are only used for SNMP GET requests, so read-only strings are sufficient. To begin discovering your network: 1. If the discovery wizard does not start automatically after configuration, click Settings > All Settings > Discover Network, and click Start. 17

19 2. To discover devices located on your network, complete the following procedure. You can choose to discover devices based on IP ranges, subnets, IP addresses and information from Active Directory Only one selection method can be used per defined discovery. In this example, IP ranges are used for discovery. For information about the different discovery methods, see Network Discovery using the Network Sonar Wizard. a. Go to IP Ranges on the Network Selection page, and click Add Range. b. For each IP range, specify both a Start address and an End address. c. Click Add Range to add more IP address ranges. Click X to delete an incorrect IP address range. d. If you have added all the IP ranges you want to poll, click Next. 3. To check the nodes polling with agents for updates, select Check all existing nodes, and click Next. For more information, see Using the Network Sonar Wizard to check agent polled nodes. 4. If the devices on your network do not require community strings other than the default strings public and private, click Next. 18

20 5. If any of your network devices require community strings other than public and private or if you want to use an SNMPv3 credential, complete the following steps to add the required SNMP credential. Repeat the procedure in this step for each new community string you want to add. When you have added all your community strings, you can highlight them, and then move them up or down in the list by using the arrows. To speed up discovery, move the most commonly used community strings on your network to the top of the list. a. Click Add New Credential. b. Select the SNMP Version of your new credential. c. If you are adding an SNMPv1 or SNMPv2c credential, provide the new SNMP Community String, and click Add. d. If you are adding an SNMPv3 credential, provide the following information for the new credential: User Name Context Authentication Method and Password/Key Privacy/Encryption Method and Password/Key e. Click Add, and click Next. 6. To discover WMI-enabled Windows devices, complete the following steps: a. Click Add New Credential. b. Choose <New credential>, and provide a Credential Name, User Name, and Password. c. Confirm the password, and click Add. d. Click Next on the Windows Credentials view. 7. On the Monitoring Settings tab, specify whether you want to include devices or nodes that only respond to ICMP, specify your preferred polling method, and click Next. By default, Network Sonar uses ICMP ping requests to locate devices. Most information about monitored network objects is obtained using either SNMP queries or, in the case of some Windows devices, WMI queries. 19

21 8. Configure the options on the Discovery Settings view, and click Next. 9. If you want the discovery you are currently defining to run on a regular schedule, select Daily or Advanced as the discovery Frequency, as shown in the following steps: a. To define a custom discovery schedule to perform the currently defined discovery repeatedly in the future, select Advanced, click Add frequency, and then provide the frequency for the discovery. b. To run the scheduled discovery daily, select Daily, and then provide the time at which you want your discovery to run every day, using the format HH:MM AM/PM. Scheduled discovery profiles should not use IP address ranges that include nodes with dynamically assigned IP addresses (DHCP). Default Discovery Scheduling settings execute a single discovery of your network that starts immediately once you click Discover. Results of scheduled discoveries are maintained on the Scheduled Discovery Results tab of Network Discovery. 10. Click Discover to start your network discovery. Because some devices may serve as both routers and switches, the total number of Nodes Discovered may be less than the sum of reported Routers Discovered plus reported Switches Discovered. Adding discovered nodes to the VNQM database Whenever the results of a discovery are requested, either at the conclusion of the Network Sonar Wizard or when Import All Results or Import New Results is clicked for a selected discovery, the Network Sonar Results Wizard opens automatically. The Network Sonar Results Wizard directs you through the process of adding discovered devices to your database. Devices must be Cisco IP SLA-capable routers that support SNMP v2 or v3. To confirm that the Cisco IOS release for your device supports IP SLA operations, visit the Cisco Feature Navigator. The following steps detail the process of selecting discovered devices for monitoring. To add the results of a network discovery for monitoring: 1. On the Device Types to Import page, select the device types you want to monitor, and click Next. 2. On the Volume Types to Import page, select the volume types you want to monitor, and then click Next. 3. Confirm that all the devices that you want to import are selected in the Import Preview list, and then click Import. 4. After the import is completed, click Finish. Imported devices are displayed in the All Nodes resource. Monitoring Call Manager Health SolarWinds VoIP and Network Quality Manager references the Cisco Management Information Base (MIB) CISCO-CCM-MIB to provide out-of-the-box monitoring capability for Cisco CallManager and CallManager Express devices. 20

22 You can also monitor Avaya Communication and Media Server devices with SolarWinds VoIP and Network Quality Manager. VNQM intercepts the CDR packets sent by the TCP protocol, as well as the RTCP data sent through UDP, and based on these data, it provides information about the call details and the call quality. To track the performance of call managers from other manufacturers, you can use universal device pollers in connection with SolarWinds Network Performance Monitor. After a call manager device has been added to the database for management, you can use the intuitive interface of SolarWinds VoIP and Network Quality Manager to track and report call-processing performance statistics for your VoIP network. Only Cisco CallManager, CallManager Express, and Avaya Communication and Media Server devices can be added to SolarWinds VoIP and Network Quality Manager as CallManager nodes. Call management devices from other manufacturers can only be monitored as a part of your VoIP infrastructure. Cisco CallManager, CallManager Express, and Avaya Communication and Media Server devices provide a different level of details: For Cisco CallManagers, you can see all information from the device Call Detail Records, such as the call source, destination, duration, or the call quality indicators. For Cisco CallManager Express devices, the information about CDR is not available, thus giving you only the details about the device status and its phone devices count. For Avaya Communication and Media Server devices, you can see information such as the call source, destination, duration, and certain call quality indicators. Adding Cisco CallManager devices Add or delete Cisco CallManager and CallManager Express devices on the Manage CallManager Nodes section of the VoIP and Network Quality Manager Settings page. The following procedure adds a Cisco CallManager device to SolarWinds VoIP and Network Quality Manager. To exercise the full benefits of monitoring Cisco CallManager devices, you can provide AXL credentials and FTP credentials to the CDR/CMR data. By downloading CDR/CMR data from CallManager devices, SolarWinds VoIP and Network Quality Manager can track the region information of each call made through your monitored Cisco CallManager device. AXL refers to Cisco's Administration XML API, which provides a mechanism to receive and modify data in the call manager's database. SolarWinds VoIP and Network Quality Manager queries the database for region information. No information is modified in the database. You can create a read only AXL account specifically for VNQM. To monitor CDR/CMR data, you must perform the following tasks to both publisher and subscriber Cisco CallManager Devices. 1. Configure the Cisco CallManager to monitor calls. For more information, see the SolarWinds Knowledge Base article, How do I configure the Call Manager for FTP. 21

23 2. Enable the AXL API. For more information, see your manufacturer's documentation. 3. Create an AXL account. For more information, see your manufacturer's documentation. The following sections give procedures for adding Cisco CallManager devices. Adding CallManager Devices to SolarWinds VoIP and Network Quality Manager The following procedure adds a Cisco CallManager device to SolarWinds VoIP and Network Quality Manager. Call managers from manufacturers other than Cisco can be monitored with VNQM if you use a custom management information base (MIB) poller specifically configured for your non-cisco call manager. For more information, see the relevant section in the Administrator Guide. To add a CallManager device to SolarWinds VoIP and Network Quality Manager: 1. In the Orion Web Console, click Settings > All Settings > VoIP & Quality Settings. 2. Click Add CallManager nodes. 3.

28 end-date(4d), end-date, or date end-time, or time cond-code If your Avaya setup makes it necessary, you can substitute certain parameters with different ones, and use them in the following way: Instead of the start-time parameter, you can use the time and sec-dur parameters. Instead of the start-time parameter, you can use the end-time and sec-dur parameters. Instead of the end-time parameter, you can use the start-time and sec-dur parameters. Instead of the time parameter, you can use the start-time and sec-dur parameters. The order in which you configure CDR parameters is not relevant. To be able to use the start-date, start-date(4d), end-date(4d), start-time, and end-time CDR custom fields, you must enable the SA8201-Start Time and the 4-Digit Year CDR Custom fields special application. You must also enable the SA8202-Intra-switch CDR by COS special application. Adding Avaya Call Manager devices to VoIP and Network Quality Manager Before adding Avaya Communication and Avaya Media Server devices, make sure that you configure the device for VNQM. For detailed information, see Managing Avaya Call Managers. When you add an Avaya call manager device, SolarWinds VoIP and Network Quality Manager uses the value of the OID (sysdescr) to identify an Avaya Communication and Media Server. Adding an Avaya Communication and Media Server to VNQM The following procedure adds an Avaya Communication and Media Server device to SolarWinds VoIP and Network Quality Manager. Call managers from manufacturers other than Cisco and Avaya can be monitored with SolarWinds VoIP and Network Quality Manager if you have SolarWinds Network Performance Monitor installed, and use a custom management information base (MIB) poller specifically configured for your call manager from other manufacturers. You cannot monitor call manager specific data, such as VoIP phones, region information, or call data. Adding Call Manager Devices from Other Manufacturers. To add an Avaya Call Manager device to SolarWinds VoIP and Network Quality Manager: 1. Log in to the Orion Web Console as an administrator. 2. Click Settings > All Settings > VoIP & Quality Settings. 3. Click Add CallManager Nodes. 4. Select an available CallManager-hosting device, and click Next. If you do not see an expected call manager device, use the Orion Web Console to add it. Make sure that you enable SNMP on the call manager device. 27

29 5. Decide whether you want to collect information about calls on this call manager. To collect information about calls on this call manager, select Enable CDR/CQR polling for this Call Manager, and click Next. If you do not want to collect information about calls on this call manager, select Add Call Manager without CDR/CQR monitoring, and click Next. For information about the configuration of the necessary CDR parameters, see Avaya CDR parameters. 6. Define the CLI credentials that let you log in to the SAT console of the Avaya Call Manager by either selecting an existing credentials set from the Select Credentials list, or by creating a new set. To create a new set, complete the following procedure: a. Enter the user name and password. b. Select the enable level from the list. c. Enter the enable password. d. In the Advanced section, select either the Telnet or the SSH protocol from the list. e. Specify the Connection Timeout. 7. Click Test to test the credentials. If the SAT account has a PIN code defined for additional authentication, the CLI credential test will fail. PINs are not supported by SolarWinds VoIP and Network Quality Manager. Disable the PIN in the Avaya Call Manager, or use a credential set for which a PIN code is not defined. 8. Click Next, and click Add Call Manager. Restrictions: The Avaya CDR/CQR Polling configuration grouping describes the configuration settings that are applicable to the Avaya Call Manager. To emit CDR or CQR (RTCP) data, use the listening ports that are displayed. The port numbers cannot be further configured through the user interface of SolarWinds VoIP and Network Quality Manager. SolarWinds VoIP and Network Quality Manager does not support the usage of survivable processors on Avaya. If you have set up survivable processors on your Avaya Communication and Media Server, VNQM does not accept CDR data. Use an NTP server to synchronize the time settings of the Avaya Communication and Media Server and the VNQM pollers. The synchronization is necessary to make sure that the CDR data and the call quality data match each other. If the time settings of the call manager and the VNQM pollers are not synchronized, the call quality data may not be displayed. Requirements for Handling RTCP Data If VNQM does not handle RTCP data correctly, the following causes are possible. Make sure that you fix these issues in order for VNQM to be able to process RTCP data. RTCP is already pointing to a different target than your VNQM instance. Both channels for CDR data are already occupied. You are using a customized data format for the CDR channel, which does not comply with the requirements of VNQM. 28

30 Adding gateways To monitor your gateways with SolarWinds VoIP and Network Quality Manager, you have to add them to VNQM as gateway nodes first. The Add VoIP Gateway page provides a wizard which helps you to add a gateway node to SolarWinds VoIP and Network Quality Manager as a gateway. Gateway nodes require CLI credentials. To add a gateway device to SolarWinds VoIP and Network Quality Manager: 1. Log in to the Orion Web Console as an administrator. 2. Click Settings > All Settings > VoIP & Quality Settings. 3.

Creating an IP SLA operation This section provides an example how you can create an HTTP IP SLA Operation on your devices and add it to VNQM for monitoring. Hypertext Transfer Protocol (HTTP) IP SLA operations measure distributed web services response times. These operations ensure that your HTTP servers are operational and performing as expected. You cannot add operations that have been previously created with SolarWinds VoIP and Network Quality Manager. If you have already created an operation with the same operation number, you must manually remove the operation from the device. To add HTTP IP SLA operations to your network devices: 1. Log in to your SolarWinds VoIP and Network Quality Manager server as an administrator. 2. Click Settings > All Settings > VoIP & Quality Settings. 3. Click Add new operations in the Manage IP SLA Operations section. 4. Select Create new operations, and click Next. 5. Select HTTP, and click Next. 6. Select the nodes you want to add to your new HTTP operations, and click Next. If you do not see your IP SLA routers in the list, you must add the devices before you can continue. For more information, see Adding Devices for Monitoring in the Web Console. 7. Enter the URL of the HTTP server, and click Next. 8. Enter the frequency for the operation to be performed. 9. Define your warning, critical, and maximum threshold values. 10. To assign a type of service (ToS) or Virtual Routing and Forwarding (VRF) name for this path, expand Advanced, and enter the type of service number and VRF name in the appropriate fields. The ToS octet is a decimal value (0-255) that sets the precedence for VoIP traffic monitored with Cisco IP SLA operations. The default ToS value used by SolarWinds VoIP and Network Quality Manager is 184, corresponding to Expedited Forwarding (EF) per hop behavior (PHB) and a Differentiated Service Code Point (DSCP) value of 46. For more information about the ToS octet, see Setting Traffic Precedence. VRFs only exist on provider edge routers (PE). A VRF is a routing and forwarding table instance, and you can have more than one VRF per PE. The VRF includes routes that are available to a certain set of sites. A VRF is named based on the VPNs it services and on the role of the CE in the topology. 11. Click Next. 12. To rename operations or edit any other operation properties, select the operations you want to modify, and click Edit. 30

32 13. Review the operations you want to create, and click Create Operations. Depending on the number of operations that are being created, this process can take several minutes. Selecting VoIP infrastructure In SolarWinds VoIP and Network Quality Manager you can monitor the health and status of your IP SLA and VoIP devices in the VoIP Infrastructure resource on the VoIP Summary View page.
