CONFIGURE FE TAGGING MODE

Determine the existing tagging mode for the FE circuit pack being provisioned. Use the TL1 rtrv-eqpt command or select View → Equipment from the System View menu, select the FE CP, then click Select. Note the VLAN Tagging Mode, Burst Size, and Credit Interval parameters.

Important!

The tagging mode must be the same on both circuit packs being connected.

When FE circuit packs are installed in the shelf, the default 802TAG mode is assigned to the circuit pack.

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 FE circuit pack being provisioned, then click Select. Note if a virtual switch ID has been assigned.

If a virtual switch ID already exists, you must delete the existing virtual switch ID before changing the tagging mode.

If a virtual switch has been provisioned, delete it by using 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.

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

Verify/Select the tagging mode (802.1TAG) in the Select VLAN Tagging Mode box.

Verify/Enter the Burst Size and Credit Interval parameter values as required, then click Apply. Read the warning message, then click OK to make your changes. Click Close to exit.

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.

ASSIGN VIRTUAL SWITCH ID TO FE PORTS

• 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.

    Note that the Virtual Switch ID for this example should be set to 123, the same ID as in the GbE circuit pack on the packet ring. Also note that LAN ports d1-2 and d1-3, and VCG d1-v1 are assigned to the virtual switch.

• 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.

    Note that the Virtual Switch ID for this example should be set to 123, the same ID as in the GbE circuit pack on the packet ring. Also note that LAN ports d1-2 and d1-3, and VCG d1-v1 are assigned to the virtual switch.

Add VCG port to Virtual Switch ID on GbE, if required.

Note that in this example, Figure 11-11, Ethernet packet ring on a UPSR, we only assigned VCGs g1-v1 and g1-v2 to virtual switch ID 123 when we created the packet ring. We now need to add VCG g1-v3 to the same virtual switch ID. Note that we should have added g1-v3 to the virtual switch when we established the packet ring.

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. Determine if VCG g1-v3 is already assigned to virtual switch ID 123.

If VCG g1-v3 is not assigned to virtual switch ID 123, use the TL1 ed-vrtsw command or select the Configuration → Data → Provision Virtual Switch command from the System View menu, select the circuit pack being provisioned, then click Select. Highlight and Select the Available AID g1-v3 to move the VCG (WAN) Port g1-v3 to the Selected AID column. Click Apply, then click Close to exit.

ESTABLISH HAIRPIN CROSS-CONNECTIONS

Determine the necessary 2-Way Hairpin STS-1 cross-connections to be made between the FE circuit pack and the GbE circuit pack.

Note that the 2-Way Hairpin cross-connections between the FE and GbE in this example must be made between the FE and GbE v3(v4) since the GbE VCG group v1 and v2 are part of the multipoint packet ring cross-connection.

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 to provision the 2-Way Hairpin cross-connections. For example, see Figure 11-12, FE to GbE Ethernet hairpin cross-connections and provisioning on packet ring.

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.

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

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 24.

• 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 21.

• 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 IS (in service), 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.

ASSIGN VLAN IDs TO ESTABLISH SERVICE

Use the TL1 ent-vlan command to assign the default VLAN ID for customer untagged frames or the customer VLAN ID for tagged frames to the associated LAN ports and VCG WAN ports on the FE and GbE circuit packs. Or, select Configuration → Data → Create VLAN command from the CIT System View menu, refer to Figure 11-12, FE to GbE Ethernet hairpin cross-connections and provisioning on packet ring.

PROVISION LAN PORTS

Use the TL1 ed-eport command to provision the LAN port parameters, or select Configuration → Equipment from the System View menu, expand the details for the Ethernet circuit pack, highlight the LAN port, then click Select. Provision parameters as required.

Reference:

Procedure 11-8: Provision Ethernet LAN port parameters

PROVISION VCGS

Use the ed-vcg TL1 command to provision the WAN (VCG) port parameters, or select Configuration → Equipment from the System View menu, expand the details for the Ethernet circuit pack, highlight the VCG port, then click Select. Provision the parameters as required.

Important!

Enable full rate end-to-end flow control for the VCGs involved in the hairpin cross-connection by setting Pause Control (psctl) to TRANSPARENT for the VCGs involved in the hairpin cross-connection. In this example you would set Pause Control to TRANSPARENT for VCG d1-v1 on the FE circuit pack, and for VCG g1-v3 on the GbE circuit pack.
