Important!

All virtual switches and cross-connections must be removed from ports 3, 4, 7 and 8 on the installed “working” circuit pack. If service is being provided on those ports, the service must be moved/removed before continuing with this procedure.

If required, use the Configuration → Data → Delete Virtual Switch and/or Configuration → Cross-Connections command to delete the required virtual switches or cross-connections on ports 3, 4, 7 and 8.

Important!

Any PTMs installed in ports 3, 4, 7, or 8 must be removed.

Remove any PTM’s from ports 3, 4, 7, or 8 on both LNW170 circuit packs.

Important!

No provisioned Link Aggregation Groups can exist on the installed working LNW170 100/1G FXS circuit pack.

From the System View, select View → Data → LA Group, select (highlight) the working LNW170 100/1G FXS circuit pack, then click Select. Verify that no Link Aggregation Groups exist on the circuit pack.

If required, select Configuration → Data → Create/Modify/Delete LA Group to delete any Link Aggregation Groups on the working LNW170 100/1G FXS circuit pack.

Procedure 11-38: Create/Modify/Delete link aggregation group (LAG)

NOTICE Service-disruption hazard

Changing the Slot Protection State of the LNW170 100/1G FXS circuit pack causes a circuit pack reset which may take up to several minutes to complete and disrupt service.

Wait until the circuit pack reset is complete before performing additional provisioning.

From the System View, select Configuration → Equipment, select the working LNW170 100/1G FXS circuit pack, then click Select. Provision the Slot Protection State to PROT.

Result:

The VLAN Tagging Mode on the unequipped companion slot becomes SWITCHED. The Ethernet Cross Connect Mode, Transmission Audit, Port Configuration, and VCG parameters become the same as on the equipped slot.

• The services and L2 provisioning on working circuit pack ports 1, 2, 5, and 6 are transferred to LAG groups 1, 2, 3, and 4, respectively.

• The same port numbers on the companion slot are members of those LAG’s.

• Any ports not in use on the working circuit pack remain so but are members of their preassigned LAG’s.

• A protection group is created and the Switch State of the working circuit pack addressed by the Configuration Equipment command (ed-eqpt) becomes Active-WAN.

Install an LNW170 in the unequipped companion slot.

Procedure 4-14: Install Gigabit Ethernet circuit packs

Select View → Equipment to access the affected circuit packs and verify that the Slot Protection State changed to Protected.

If required, use the TL1 ed-eport command to provision the LAG member LAN ports 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.

Reference:

Procedure 11-8: Provision Ethernet LAN port parameters

If required, use the TL1 ent-erate command to provision 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.

Reference:

Procedure 11-23: Provision Ethernet quality of service (QoS) - LNW70/LNW170

If required, use the TL1 ed-lagrp command to modify the LAG, or select Configuration → Data → Create/Modify/Delete LA Group from the System View menu. Select (highlight) the circuit pack, then click Select.

Modifying a LAG consists of changing the hashtype, or changing the protocol parameter.

• Hash Type

  The basis for assigning a conversation to a link.

  . Valid values are:

  • MAC - Use Source Address/Destination Address (SA/DA) (initial value)

  • IP - Use Source IP Address/Destination IP Address (SIP/DIP). This may allow better load distribution when connected to a router where the MAC SA/DA are constant or nearly constant and the traffic is IP.

• Protocol.

  The protocol used for Link Aggregation.

  Valid values:

  • LACP - IEEE Std 802.3™-2002 Link Aggregation Control Protocol (initial value).

  • NONE - Aggregation among members is forced. Any Link Aggregation protocol messages received are ignored and none are sent.

Click twice in the Hash Type or Protocol box. Select the Hash Type or Protocol value, as required. Click Apply, read the warning message then click Yes to execute the command. Click Close to exit.

As required, complete other L2 provisioning (for example, virtual switch, vlan, spanning tree groups, cross-connections) using the procedures in this chapter.

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.

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.
