CONFIGURE TAGGING MODE

Determine the existing tagging mode for the circuit pack being provisioned. Use the TL1 rtrv-eqpt command or select View → Equipment from the System View menu, select the CP, then click Select. Note the VLAN Tagging Mode and other parameter values.

The VLAN Tagging Mode for the LNW66/67/68 circuit packs must be set to TRANS or 802.1TAG. The VLAN Tagging Mode for the LNW70/LNW170 circuit packs must be set to SWITCHED.

When GbE circuit packs are installed in the shelf, the default "NO TAG" mode is assigned to the circuit pack. When non private line FE circuit packs are installed in the shelf, the default "802.1TAG" mode is assigned to the circuit pack.

If you are going to change the VLAN Tagging Mode that presently exists AND a virtual switch ID already exists, you must delete the existing virtual switch ID before changing the tagging mode.

Determine if a virtual switch ID has already been assigned to the LAN/WAN ports used for this service. Use the TL1 rtrv-vrtsw command or select the View → Data → Virtual Switch command from the System View menu, select the GbE circuit pack being provisioned, then click Select. Note if a virtual switch ID has been assigned.

If required, use the TL1 dlt-vrtsw command or select the Configuration → Data → Delete Virtual Switch command from the System View menu, select the circuit pack being provisioned, then click Select. Highlight the VRTSW ID being deleted, then click Apply.

Read the warning message, then click Yes to execute the command. Click Close to exit.

Select the Configuration → Equipment command from the System View menu (or use the TL1 ed-eqpt command), select the circuit pack being provisioned, then click Select.

Verify/Select the tagging mode (802.1TAG, TRANS [LNW66,67,68], or SWITCHED [LNW70/LNW170]) in the VLAN Tagging Mode box.

Verify/Enter other parameter values (for example, Burst Size, Credit Interval[LNW66/67/68], Ethernet Cross Connect Mode and Port Configuration [LNW70/LNW170]), as required, then click Apply. Read the warning message, then click OK to make your changes. Click Close to exit.

Procedure 11-10: Provision Ethernet circuit pack parameters

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 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.

Creating virtual switches using the ent-vrtsw TL1 command or Configuration → Data → Create Virtual Switch command from the System View menu requires you to select the circuit pack and provision the following parameters :

• Virtual Switch ID (vrtswid) - Value in the range of 1–4095 for the LNW66/67/68 circuit packs. Value in the range of 1–16 for the LNW70/LNW170 circuit packs.

• Virtual LAN Tagging Mode (tagmd) - Value of 802.1TAG or Transparent. Applies to LNW70/LNW170 only.

• Ethernet (LAN) Ports (eplst) - List or selection of LAN ports associated with the virtual switch ID.

• VCG (WAN) Ports (vcglst) - List or selection of VCG ports associated with the virtual switch ID.

ASSIGN VIRTUAL SWITCH ID

• For circuit packs not yet in service with no virtual switch assigned:

  • Select Configuration → Data → Create Virtual Switch command from the CIT System View menu (or use the TL1 ent-vrtsw command) to create an assigned virtual switch ID or

    For the LNW70/LNW170 circuit pack, select the required Virtual LAN Tagging Mode (802.1TAG or Transparent).

• For circuit packs not yet in service with a virtual switch assigned:

  • Select Configuration → Data → Delete Virtual Switch command from the CIT System View menu (or use the TL1 dlt-vrtsw command) to delete an assigned virtual switch ID, if a different virtual switch ID is required.

  • Select Configuration → Data → Create Virtual Switch command from the CIT System View menu (or use the TL1 ent-vrtsw command) to create a new virtual switch ID containing the selected LAN/WAN ports.

    For the LNW70/LNW170 circuit pack, select the required Virtual LAN Tagging Mode (802.1TAG or Transparent).

• For circuit packs in service, on only one set of ports, with a virtual switch assigned:

  • select Configuration → Data → Provision Virtual Switch command from the CIT System View menu (or use the TL1 ed-vrtsw command) to remove the required ports from a virtual switch.

  • Select Configuration → Data → Create Virtual Switch command from the CIT System View menu (or use the TL1 ent-vrtsw command) to create a new virtual switch ID containing the required LAN/WAN ports.

    For the LNW70/LNW170 circuit pack, select the required Virtual LAN Tagging Mode (802.1TAG or Transparent).

ESTABLISH SONET CROSS-CONNECTIONS

Determine the necessary cross-connections to be made at each Ethernet terminating node and any pass-through cross-connections to be made at any non terminating nodes in the network.

One at a time at each node in the network, use the TL1 ent-crs-sts1 command to provision the 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 non terminating node to provision the 2-Way Point-to-Point, Through pass-through cross-connections. Use the Cross-Connection Wizard at each terminating node to provision the Ethernet Multipoint (unswitched) cross-connections. For example, see Figure 11-4, Ethernet packet ring on a UPSR.

Reference:

Refer to Procedure 11-15: Make cross-connections for Ethernet service for cross-connection examples.

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

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).

Reference:

Procedure 11-25: Provision LCAS, add/enable/remove tributaries

After all cross-connections are made, click on the Alarm List button on the System View window and verify no alarms are present.

If alarms are present, look for missing or improperly made cross-connections.

Reference:

Alcatel-Lucent 1665 Data Multiplexer Extend (DMXtend) Alarm Messages and Trouble Clearing Guide, 365-372-326

Important!

For LNW70/LNW170 circuit packs, at least one tributary at each end of the circuit must be Enabled in order for the VCG to go in service.

If required, after all cross-connections have been made, verify that the WAN (VCG) Ports being used have gone in service at each terminating node. From the System View menu at each terminating node, select View → Data → Ethernet/Data/VCG Port.

Result:

The View LAN (Ethernet) WAN (VCG) Port window opens.

Expand the details for the circuit pack being used. Select the required VCG v( ) port, then click Select at the bottom of the window. Verify the VCG AID is correct at the top of the parameter display.

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),

  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.

CREATE SPANNING TREE GROUP

If required, determine a preferred spanning tree configuration (span to be blocked under nominal conditions), the preferred root node, and spanning tree root priorities for this service.

Note that it is not necessary to determine a preferred spanning tree configuration. A default spanning tree configuration is configured when you establish the spanning tree group.

Reference:

Procedure 11-16: Create preferred spanning tree configuration

Select Configuration → Data → Create Spanning Tree Group command from the CIT System View menu (or use the TL1 ent-stgrp command) to assign and provision the parameters for the ports involved in the spanning tree group. For example, see Figure 11-4, Ethernet packet ring on a UPSR.

Important!

Networks running 802.1d STP support a maximum of up to nine nodes participating in a spanning tree. Networks with more than nine nodes will not reconfigure properly. Spanning tree default parameters support a network of up to nine nodes.

Networks running 802.1w rapid spanning tree protocol support more than nine nodes participating in a spanning tree. To support more than nine nodes in the spanning tree, the maximum age timer must be increased. Note that spanning tree restoration time increases as the number of nodes increase.

If the network consists of more than nine (9) nodes which are participating in the spanning tree configuration, use the following formula to determine the proper setting for the spanning tree maximum age timer (stmaxage): 2N + 6, where N equals the number of nodes.

Example

If the network consists of 20 nodes, then the stmaxage timer should be set to 46 seconds: 2 x (20) + 6 = 46.

Repeat all the assignments in this procedure at each Ethernet node in the network.
