1 RADIO PMs General information on the radio performance monitoring process The performance monitoring (PM) gives indication on the quality of the service and the levels of the Tx power and Rx power. Quality of service PM is performed in accordance with G.826 and G.784. It is assumed that the quality of the single tributary (E1,...) can be derived from the quality of the aggregate signal, therefore no dedicated quality of service PM is foreseen on the single tributaries. Considering one section (see below figure), one current register is for 15 min report and one for 24 h report; 96 history data can be stored for 15 min report and 8 history data for 24 h report. N.B. The 15 min Performance Monitoring data are stored in the History Data report only if errors have been occurred. The 24 h Performance Monitoring data are always stored in the History Data report. Two different radio sections can be monitored: Radio Hop Section: the section between two radio stations inside the protection section Radio Link Section: the section identifying the protected section. Figure 296. Radio sections The performance reports can be of 2 different types: 15 minutes 24 hours The following description explains the functions to provide the PM process with a granularity period of 15 min. The same functions are provided for 24 h PM process. The PM are of HOP or LINK type: HOP refers to the PM before the RPS switch. LINK refers to Performance Monitoring after the RPS switch. The current report can be seen (and configured) and the history log can be seen. Two types of counters are supported: 1) Radio Counters 2) Analog Counters 3DB18809AAAA Issue 1 523/980

2 [1] The Radio counter parameters are the following: Errored Seconds Severely Errored Seconds (N.B.) Background Block Error Unavailable Seconds N.B. According to ITU-T G.826 a second is declared Severely Errored Second if it is a second period with more than 30 % of errored blocks or at least one defect. [2] The Analog counter parameters are the following: Minimum level: minimum power level during the elapsed time Avarage level: avarage power level during the elapsed time Maximum level: maximum power level during the elapsed time RADIO PMs performance monitoring procedures RADIO Performance Monitoring provides quality data regarding the radio channels. To the RADIO measurements thresholds can be associated. See procedure which follows. Only the quality of the aggregate signal is provided. 1) In the left area select bar RADIO PM. The selected bar is moved to the upper part of the left tree area. 2) Select the slot housing the MD300 or the MPTACC unit. 3) Select the Direction, in this example Direction #7.1/8.1 (MPT-HC). 4) Select the granularity tab-panel (15 min/24h).

26 3.22 VLAN management Two different ways to manage the Ethernet traffic are allowed: 802.1D (MAC Address Bridge) 802.1Q (Virtual Bridge) D When the NE is configured in this mode (default configuration), the Ethernet traffic is switched according to the destination MAC address without looking the VLAN. The packets from the user Ethernet ports having the VLAN ID out the allowed range (0 and ) are dropped. The packets having a VLAN ID already used for a TDM flow are accepted. Figure D VLAN management 548/980 3DB18809AAAA Issue 1

27 Q When the NE is configured in this mode, the management of Ethernet traffic looking the VLAN is enabled. In this modality, one VLAN will be assigned to all Ethernet frames inside the MPR network. WARNING: The VLAN ID values configurable must be in the range The VLAN IDs already defined to cross-connect internal flows (i.e. TDM2TDM, TDM2ETH) cannot be used. The management system prohibits the definition of VLAN ID already used. The VLAN ID must be different also from the Flow Id associated to E1 tributaries not yet cross connected Figure Q VLAN management (default VLAN only) Note on LAG: if a Radio LAG or an Ethernet LAG has been created, they will appear in the VLAN management, as shown in the next figure. 3DB18809AAAA Issue 1 549/980

28 Figure Q VLAN management (default VLAN only) with LAG VLAN 1 Management VLAN-ID 1 is automatically defined by the NE when the 802.1Q bridge type is selected. VLAN-ID 1 is shown to the operator, but it cannot be neither changed nor deleted. All the user Ethernet ports (enabled and disabled) and all the radio ports are members of the VLAN 1. In egress VLAN-ID 1 is always removed from all the ports. Buttons New: to create a new VLAN (refer to VLAN table management) Edit: to change the parameters of a VLAN (VLAN name, VLAN member ports, VLAN untagged ports in egress). Delete: to delete a VLAN-ID. It is possible to remove a VLAN-ID from the VLAN-ID table even if this VLAN-ID has been already configured on one or more user ports as Port VLAN to be added in ingress to untagged frames. As consequence, the VLAN-ID=1 and PRI=0 are added to the untagged frames received on this port. Before applying this deletion, a confirmation of the operation is shown to the operator. Export: to export the VLAN configuration in a file with extension CSV. The file can be stored in the PC to be read later. 550/980 3DB18809AAAA Issue 1

29 Filter: by inserting a name in the "Filter by Name" box and by clicking on Filter will be displayed in the table only the VLAN, which name corresponds (totally or partially) to the name written in the "Filter by Name" box. Clear Filter: by clicking this button all the VLAN created in VLAN table will again appear. Refresh: the VLAN table is updated VLAN Table Management Figure 320. VLAN Table Management [1] VLAN ID field: Enter the VLAN ID (the values configurable must be in the range ) N.B. The VLAN IDs already defined to cross-connect internal flows (i.e. TDM2TDM, TDM2ETH) cannot be used. [2] VLAN Name field: Enter the VLAN Name: a text string of up to 32 characters. N.B. There is no check on unambiguity name. [3] VLAN Ports field: Select the ports members of this VLAN by putting a check mark on the relevant check box. All the user Ethernet ports and all the Radio directions can be considered. Both enabled and disabled user Ethernet ports (radio ports when declared are implicitly enabled) can be member of a VLAN. This means that a disabled port can be configured as a member of a VLAN and a port already member of a VLAN can be disabled continuing to be a member of the same VLAN. [4] Untagged Ports field: Select, among the ports belonging to this VLAN (members), the untagged ports (in egress the VLAN will be removed from the frames). Only the user Ethernet ports, enabled and disabled, are manageable. The VLAN cannot be removed from the radio ports (with the exception of the VLAN 1). N.B. N.B. The VLAN-ID values allowed are in the range By default, for the VLAN IDs defined, all the ports are members and the Untag flag is set to False, which means all the frames are transmitted with Tag. Tagged frames If one tagged packet with VLAN-ID X is received on a port which is not member of the VLAN- ID X, the packet is dropped. 3DB18809AAAA Issue 1 551/980

30 In Figure 321 three VLANs have been created (VLAN 2, 3 and 4). Figure Q VLAN management N.B. When an ODU300/MPT-HC or MPT-MC port which is member of a VLAN, is unconfigured, the operation is denied stating that "Operation not permitted: the board <board no> is member of a static VLAN". To unconfigure this board, the user must first navigate to VLAN Configuration window and remove this port from the static VLAN. 552/980 3DB18809AAAA Issue 1

31 Ethernet Ring If an Ethernet Ring has been created, the VLAN ID of the R-APS relevant to the ERP Instances must be inserted in the VLAN Configuration as shown in the next figure. Figure 322. R-APS VID 3DB18809AAAA Issue 1 553/980

32 3.23 Annex A: Network Element Overview The Network Element Overview (NEtO) is the starting point of the WebEML application. NEtO functions require to know the NE identity by means the related IP Address. Only one NE can be managed in a NEtO session. The User Interface is provided by the NEtO Main View described below Main view When NEtO starts, the main view screen is shown in Figure 323. This screen has three specific areas: Figure 323. NEtO main view: initial screen NE Configuration area: displays NE general information (left side); Status & Alarms area: reports supervision status and alarms (right side); Discovered NEs: in the lower part is shown the list of the discovered NEs. With a double click on a row the IP address of the NE in the row automatically is written in the NE Info field "Show" and "Alarm Monitor" buttons are enabled when a NE is supervised only. Supervision starts as soon as the operator writes an IP address in the specific field and press the "OK" button. Note: For more information on the Alarm Monitor application refer to Menu Diagnosis > Alarms in the NE. NEtO Main view can also be reduced by using the shrink glass ( ) button in the Menu Bar. Figure 324 shows the reduced NEtO view, allowing the operator to save screen space while continuously checking supervision and alarms status. Gray icons mean that supervision is not active. The magnifying glass ( ) button allows to show the normal NEtO main view (see Figure 323). The alarm severity icon (shown in Figure 323 and Figure 324) appears in operating system "tray bar", close to system clock and other system software icons. 554/980 3DB18809AAAA Issue 1

33 Figure 324. NEtO main view: reduced screen This icon also has a specific tooltip, visible when mouse cursor is moved over it, that will show: name of application, NE IP address, and highest severity alarms number. The tray-bar icon is present in the Windows system bar (in the lower part of the screen). The tray-bar icon takes the color of the most severe alarm. The tray-bar icon is not interactive and does not present any menu or executable command if clicked either with left or right mouse button NE Configuration area The panel is divided in three sections: [1] NE Info section, containing information related to NE addressing; [2] NE Description section, with information about NE characteristics; [3] Command Buttons section, providing buttons to manage NEtO functions NE Information This area is related to wanted NE identification (Figure 325). Figure 325. NEtO NE Configuration View: NE Information "IP Address or DNS name" field: insert the NE IP address or DNS name, if the network can provide this facility. "OK" button will start supervision on specified NE, if reachable. Keyboard shortcut "Alt + o" behaves as clicking on "OK" button with mouse. Whether the IP address is correctly written, other than clicking on "OK" button, supervision process will start on specified NE by pressing "enter" (carriage return) key on keyboard. 3DB18809AAAA Issue 1 555/980

34 NE Description This area contains some parameters displaying general information about the supervised NE (Figure 326). Figure 326. NEtO NE Configuration View: NE Description Note: If you are connected to an ETSI equipment the type is 9500 MPR-E. If you are connected to an ANSI equipment the type is 9500 MPR-A.

35 Status & Alarms area Information on supervision status and active alarms are shown in this area (Figure 328). Figure 328. Main View: Status & Alarms Round-shaped icons change their colours according to current NEtO functions and situation. With respect to "Supervision" status: green colour means that supervision function is ongoing, red colour means that NE link does not work, gray icons mean that supervision is not active (to be started). Alarm synthesis contains the list of the alarms listed by severity: whether an icon is not grey, means that such kind of severity contains one alarm at least. The round-shaped icons change the colour and the letter inside according to the severity of the active alarms: orange (letter M): Major alarm yellow (letter m): Minor alarm blue (letter W): Warning alarm Note: the Indeterminate alarms are not supported Supervision Function The supervision function allows operator registering a new manager inside NE MIB and performing cyclic (periodic) monitoring on connection. To start supervision, the operator must specify NE IP address in the "IP Address" field and then simply press "OK" button. If supervision succeeds, screen is updated with information retrieved from NE and supervision icon changes its colour from gray to green stating NE is correctly supervised. When a supervision error, a link down or other problems arise during supervision, icon will become red. Alarm Synthesis area will be updated as well. Clicking on "Show" button, NEtO will open the WebEML (JUSM/ WebEML) for MPR equipment. To close an ongoing supervision, simply click on "Exit" button (this will also close NEtO) or change NE IP address and click "OK" button to start supervision procedure on a different NE (this will stop previous supervision). 3DB18809AAAA Issue 1 557/980

36 Menu bar (New) (Open) (Community String): refer to par NEtO can manage and organize a list of favorite NEs by showing operator a table containing such data. Using both (New) and (Open) icons, the operator will be able to open NEs table modal window (see Figure 329). "Open" icon allows opening a previously saved file containing a list of NEs. "New" icon allows creating a new list, specifying the file name containing its data, only when those data will be saved. Window allows the operator managing its NEs data by: "Get Current" button is used to read information from main NEtO view. This operation will always add a new line in NE list table with all information related to currently supervised NE. This happens even though a NE with corresponding IP address is still present in the list; "New" button, adding a new NE from scratch. This allows the operator to fill the "IP Address" field only with its needed NE. "Remove" button, removing a selected NE; "Set Current" button, filling main NEtO view IP address with datum from selected NE. The operator must previously select a valid line in NEs table and then click on "Set Current" button so filling NEtO main window data. This operation will automatically close the NE list window but does not start supervision on set NE; "Save" button, saving table list in a specified file. All data are saved in a custom XML format called "NEtO" and this structured file will contain all data shown in Figure 323 related to all NEs added to the list. Figure 329. NEtO List Management 558/980 3DB18809AAAA Issue 1

37 The operator can have its own NEs lists repository, containing all.neto files that it produced with NEs information inside. To close this window click on "Close" button. The operator can see the data related to NEs as shown in Figure 329. As for NEtO main window, even NE list window allows using keyboard and hotkeys to perform operations. Through: Keyboard shortcut "Alt + g" behaves as clicking on "Get Current" button with mouse; Keyboard shortcut "Alt + s" behaves as clicking on "Set Current" button with mouse; Keyboard shortcut "Alt + n" behaves as clicking on "New" button with mouse; Keyboard shortcut "Alt + r" behaves as clicking on "Remove" button with mouse; Keyboard shortcut "Alt + v" behaves as clicking on "Save" button with mouse; Keyboard shortcut "Alt + c" behaves as clicking on "Close" button with mouse. This icon opens the current list of the favourite NEs, if the list has been previously saved. (Magnifying glass) NEtO Main view can also be reduced by using the shrink glass ( ) button. Suggested usage sequence for NEtO interface and NE list 1) Fill NEtO main view "IP Address" field with NE IP address; 2) Start supervision by clicking "Ok" button; 3) Open the NEs table (any method, through "New" or "Open" button); 4) Click on "Get Current"; 5) "Save" the list and "Close" the list window. This operation will produce a clean and up-to-date NEs table list. The NE table lists are not updated, if the operator will modify, NE site name site location or even IP address. Such data are used for references purposes, but the operator must take care to keep them updated. 3DB18809AAAA Issue 1 559/980

38 CS (Community String) To access the Community String menu click on the CS icon on the right corner on the upper part of NEtO. The menu Community String Request allows to get/change the data regarding the Community String, if necessary, and only if the NE Administrator has defined a community string (different from the default value) for the specific NE you want to login. To proceed, you must know this string, and you must write it before to start the Supervision of such NE. Insert the Community String (1) then click OK (2). Figure 330. Community String request step 1 Button Use Default resets the community string at the default value, at NEtO side only. Figure 331. Community String request step 2 Now, insert the NE IP address in the NE Info area, click on OK to start the Supervision of such NE. Warning: The same Community String must be inserted in the NE by using the WebInterface. Open a WEB_browser and enter address of the NE. The following screen opens. 560/980 3DB18809AAAA Issue 1
