Procedure 11-38.1: Create/Modify/Delete LAG on LNW70/LNW170 (unprotected)

- Overview

Use this procedure to create/modify/delete LAG groups on the LNW70 or an unprotected LNW170.

The Configuration → Data → Create/Modify/Delete LA Group command ( ent-lagrp/ed-lagrp/dlt-lagrp TL1 command) from the System View menu allows you to create/delete or modify a LAG on the LNW70 or an unprotected LNW170. LAN ports are managed using the Configuration → Equipment command ( ed-eport TL1 command) from the System View menu.

See Link Aggregation, LAG rules for unprotected LNW70/LNW170, LAG rules for protected LNW170 and LAG definitions for additional information.

Important!

It is recommended that cables associated with members of a LAG not be connected until the group is defined, else a loop may be formed.

DANGER 

NOTICE

Service-disruption hazard

If the Ethernet circuit pack is already providing service, changing tagging mode will take down any existing service. The existing tagging mode cannot be changed without removing all existing cross-connections and virtual switch provisioning.

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 LNW70/LNW170 circuit packs must be set to SWITCHED.

Changing the vlantagmd is service affecting. Changing from NOTAG mode to another mode may result in an inconsistency between the mode and cross-connects that have been set. This will cause a tag-mode and cross-connect inconsistency alarm.


4

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.


5

Verify/Select the tagging mode SWITCHED in the VLAN Tagging Mode box..


6

Verify/Enter other parameter values (for example, Ethernet Cross Connect Mode and Port Configuration, as required, then click OK.

Reference:

Procedure 11-10: Provision Ethernet circuit pack parameters


7

Determine the LAN ports required for the LAG group(s). LAN ports must be the same rate.


8

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

Reference:

Procedure 11-8: Provision Ethernet LAN port parameters

Important!

The first LAN port (leadport) assigned to the LAG group being created must already be a member of a virtual switch. The second member port of the LAG must NOT be a member of a virtual switch.

Use the rtrv-vrtsw TL1 command or View → Data → Virtual Switch to determine the assignment of virtual switches for the port(s) being provisioned.

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 1-16 for the LNW70/LNW170 circuit packs.

  • Virtual LAN Tagging Mode (tagmd) - Value of 802.1TAG or Transparent.

  • 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/ports 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 for the LAG leadport.

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

  • For circuit packs/ports not yet in service with a virtual switch assigned:
    • If a different virtual switch ID is required or to remove a member port from the virtual switch, select Configuration → Data → Delete Virtual Switch command from the CIT System View menu (TL1 dlt-vrtsw command) to delete an assigned virtual switch ID, or select Configuration → Data → Provision Virtual Switch command from the CIT System View menu (TL1 ed-vrtsw command) to remove a member port from the existing 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 for the selected LAG leadport, if required.

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


10

The first LAN port (leadport) assigned to the LAG group being created must already be a member of a virtual switch. The second member port of the LAG must NOT be a member of a virtual switch.

Select Configuration → Data → Create/Modify/Delete LA Group command from the CIT System View menu (or use the TL1 ent-lagrp command) to create the LAG group. Select the circuit pack and provision the parameters as required.

Reference:

Table 11-15, ENT-LAGRP command provisionable parameters


11

If required, use the TL1 ed-eport command to provision the LAN port and LAG port parameters, or select Configuration → Equipment from the System View menu. Expand the details for the circuit pack, select the LAG group or expand the details for the LAG group, highlight the member LAN port, then click Select. Provision the parameters as required.

Note that these parameters may have already been inherited from the leadport when the LAG was created. The lead port's membership in the VS is transferred to the LAG, as well as VLAN memberships and QoS services. Other Layer 2 provisioning (ed-eport) is also copied to the LAG. Use the View → Equipment command from the System View menu to select the port and verify provisioning.

Reference:

Procedure 11-8: Provision Ethernet LAN port parameters


12

A default port tag (Virtual LAN tagging mode Transparent) or default VLAN (Virtual LAN tagging mode 802.1 Tag) must be provisioned for the LAG group in order to pass any untagged frames.

Note that these parameters may have already been inherited from the leadport when the LAG was created. The lead port's membership in the VS is transferred to the LAG, as well as VLAN memberships and QoS services. Other Layer 2 provisioning (ed-eport) is also copied to the LAG. Use the View → Equipment command from the System View menu to select the port and verify provisioning.

Perform one of the following as required:

  • Virtual LAN tagging mode — 802.1 Tag: Use the TL1 ent-vlan command or Configuration → Data → Create VLAN command from the System View menu to create the default VLAN for untagged traffic for the selected LAG group.

  • Virtual LAN tagging mode — Transparent: Use the TL1 ed-eport command or Configuration → Data → Create Port Tag command from the System View menu to create the default Port Tag for untagged traffic for the selected LAG group.


13

If required, use the TL1 ent-erate command to provision/adjust the LAG related QoS parameters, or select Configuration → Data → Provision QoS Service from the System View menu. Expand the details for the circuit pack, highlight the LAG port, then click Select. Provision the parameters as required.

Note that these parameters may have already been inherited from the leadport when the LAG was created. The lead port's membership in the VS is transferred to the LAG, as well as VLAN memberships and QoS services. Other Layer 2 provisioning (ed-eport) is also copied to the LAG. Use the View → Equipment command from the System View menu to select the port and verify provisioning.
