Procedure 11-12: Establish a dedicated multiple point private line UPSR protected GbE service (transparent mode)

- Overview

This procedure provides an example for configuring a dedicated multiple point private line UPSR protected GbE Ethernet service using the Transparent tagging mode.

This procedure illustrates a dedicated bandwidth, private line service with per link bandwidth granularity with multiple connections. Although this procedure uses the transparent mode, this configuration could use the 802.1q tagging mode with VLAN assignments. Cross-connections and VCG assignments are the major considerations in this type of configuration. See Figure 11-9, Dedicated multiple point GbE using transparent tagging mode and Figure 11-10, Dedicated multiple point GbE private line cross-connections.

This procedure uses TL1 commands and specific WaveStar® CIT menu selections to illustrate the detailed provisioning parameters. If you prefer, you can use the Data Provisioning Wizard to perform the provisioning in this procedure. From the System View menu, select Configuration → Ethernet Service to invoke the wizard.

- Privilege level

You must login as either a Privileged or General user to complete this procedure.

Important!

On connected Gigabit Ethernet devices with autonegotiation turned on/enabled, if transmission is interrupted in one direction of transmission on a Gigabit Ethernet device, then transmission will also be disabled in the other direction. For example, if one fiber in a transmit/receive pair is cut, then one-way transmission on the other fiber can be maintained only if autonegotiate is turned off/disabled and the link state is forced good at the transmit source equipment.

- Before you begin

Prior to performing this procedure, refer to Before you begin and Required equipment n this chapter and you must have complete work instructions for this procedure that detail:

  • The network configuration and the terminating Ethernet nodes.

  • The shelf slots, circuit packs, ports, and VCGs being provisioned.

  • The number and type of cross-connections to be made at each node.

  • The tagging mode (transparent) and virtual switch ID.

Steps

Use this procedure as an example for configuring a dedicated multiple point private line UPSR protected GbE Ethernet service using the Transparent tagging mode.

 
1

Use the WaveStar® CIT to log in to each of the terminating nodes, if not already performed.

Reference:

Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar® CIT session


2

On the System View menu, select Administration → OSI Neighbor Map command and note the NEs connected to Main 1 and Main 2.

Access each of the NEs identified and select the Administration → OSI Neighbor Map command and note the NEs connected to Main 1 and Main 2.

Repeat the above until the backbone ring can be sketched.

Important!

If a drawing of the network is not provided with the work instructions, it is recommended that you draw a simple diagram of the ring (indicating node-to-node connections) and list each node's TID.

Result:

The OSI Neighbor Map window opens.


3

Verify that the system configuration is the same as specified on your work instructions.


4

From your work instructions, determine the circuit pack, port, and cross-connections to be made at each node associated with the service to be established. Refer to Figure 11-9, Dedicated multiple point GbE using transparent tagging mode and Figure 11-10, Dedicated multiple point GbE private line cross-connections for provisioning at each node.


5

At each node in the network, use the View → Cross-Connections command from the System View menu at each node to verify that the new cross-connections are available for assignment at each NE. If any of the new cross-connections are already assigned, you must resolve the problem before continuing with this procedure.

DANGER 

NOTICE

Service-disruption hazard

Once a virtual switch is created and service has been established on the circuit pack, you cannot delete the virtual switch without interrupting service.

If the service you are establishing in this procedure is a second service on an existing GbE circuit pack with all LAN/WAN ports in the same virtual switch, then the existing virtual switch ID must be retained or the ports not in service must be removed from the existing virtual switch and added to a new virtual switch ID.

ASSIGN VIRTUAL SWITCH ID

  • For circuit packs not yet in service with no virtual switch assigned:
    • Use the TL1 ent-vrtsw command to create an assigned virtual switch ID or select Configuration → Data → Create Virtual Switch command from the CIT System View menu.

      For the LNW70/LNW170 circuit pack, select Transparent for the Virtual LAN Tagging Mode.

  • For circuit packs not yet in service with a virtual switch assigned:
    • Use the TL1 dlt-vrtsw command to delete an assigned virtual switch ID or select Configuration → Data → Delete Virtual Switch command from the CIT System View menu, if a different virtual switch ID is required.

    • Use the TL1 command ent-vrtsw command or select Configuration → Data → Create Virtual Switch to create a new virtual switch ID containing the selected LAN/WAN ports.

      For the LNW70/LNW170 circuit pack, select Transparent for the Virtual LAN Tagging Mode.

  • For circuit packs in service with a virtual switch assigned:
    • Use the TL1 ed-vrtsw command or select Configuration → Data → Provision Virtual Switch command from the CIT System View menu to remove the required ports from a virtual switch.

    • Use the TL1 command ent-vrtsw command or select Configuration → Data → Create Virtual Switch to create a new virtual switch ID containing the required LAN/WAN ports.

      For the LNW70/LNW170 circuit pack, select Transparent for the Virtual LAN Tagging Mode.

ESTABLISH SONET CROSS-CONNECTIONS

Determine the necessary cross-connections to be made at each terminating and non terminating node in the network.

Important!

Note that cross-connections at the terminating nodes are add/drop and cross-connections at the non terminating nodes are pass-through.


15

One at a time at each node in the network, use the TL1 ent-crs-sts1 command to provision the pass-through and add/drop cross-connections. Or, select Configuration → Cross-Connections from the System View menu to start the Cross-Connection Wizard. Use the Cross-Connection Wizard at each of the nodes in the network to provision the cross-connections.

Note that the sum of the three individual STS-1 links in an OC-12 ring configuration cannot exceed a total of 12 STS-1s.

Reference:

Procedure 11-15: Make cross-connections for Ethernet service


16

From the System View menu, select View → Cross-Connections at each node to verify that the proper connections have been made.


17

Important!

For LNW70/LNW170 circuit packs, each tributary cross-connected to a VCG must be Enabled before it becomes an active member of the VCG. Select View → Data → Ethernet/Data/VCG Port to verify that VCG Membership has been Enabled in both Input and Ouput Direction.

If required, use the TL1 ed-vcgtrib command to enable tributaries, or from the System View menu at each node, select Configuration → Equipment. Expand the details for the circuit pack and VCGs being used. Highlight the tributary (Trib) being enabled then click Select.

Select Enabled for the VCG Membership in both the Input and Output Direction. Click Apply, read the warning message, then click Yes to execute the command. Repeat this step for each tributary being enabled. Click Close to exit.

When Input VCG Membership (source) (inmbs) is enabled, the VCG tributary is a member of the VCG in the source direction (towards the SONET network). When Output VCG Membership (sink) (outmbs) is enabled, the VCG tributary is a member of the VCG in the sink direction (away from the SONET network).

22

Click on the VCG Data tab. Under the Fault section of the parameter display, verify the VCG Monitoring Mode is IS (in service). If the VCG Monitoring Mode is IS, proceed to Step 23.

  • If the VCG Monitoring Mode is NMON (Not Monitored),

    Perform the following:
    1. Click Close to exit this window. From the System View menu, select Configuration → Equipment. Expand the details for the circuit pack being used, then select the required VCG v( ) port and click Select at the bottom of the window.

    2. In the parameters display area, click the VCG Data tab. Under the Fault section, select AUTO for the VCG Monitoring Mode.

    3. Click Apply at the bottom of the window then click Yes in the warning message to execute the command.

    4. Click Close to exit the window, then repeat this procedure from Step 20.

  • If the VCG Monitoring Mode is AUTO:

    Look for missing or improperly made cross-connections. Verify that the proper cross-connections were made to the correct VCG at each terminating node.

    If proper cross-connections have been made, then indications are that either the far-end or near-end circuit pack at each end of the span has failed or must be reset. If the circuit pack already has service established on another pair of VCGs, the following will interrupt service.
    • Log in to the NE at the far end of the span that connects to the near-end VCG not in service. Select the Fault → Reset → Smart Pack command from the System View menu, then select the circuit pack to be reset. Click Apply. Read the warning message, then click Yes. Wait until the alarms clear, then check the VCG Monitoring Mode again. If the VCG Monitoring Mode does not go in service (IS), then reset the near-end circuit pack and check the VCG Monitoring Mode.

    • If, after resetting the circuit packs, the VCG is still not in service, replace, one at a time, the far-end and near-end circuit packs.
