To create an MC LAG group

Purpose

Perform this procedure to create an MC LAG group. Consider the following before you create an MC LAG group:

  • You can create an MC LAG member only on an Ethernet MDA.

  • MC LAG member ports must be in Access mode.

  • The NFM-P assigns the same LACP key, system ID, and system priority to each MC LAG member.

  • MC LAGs are not supported when MAC subnetting is enabled.

Steps
 

Choose Manage→Redundancy→Node Redundancy from the NFM-P main menu. The Manage Node Redundancy form opens.


Choose MC Peer Group (Multi-Chassis) and click Search.


Select an MC peer group and click Properties. The MC Peer Group (Edit) form opens.


Click on the Associated Groups tab.


Right-click on the MC Lag object in the navigation tree and choose Create MC LAG Group. The MC LAG Group (Create) form opens.


Configure the required parameters.

The LACP Key, System ID, and System Priority parameters must be left at the default when the Standby Signalling parameter is set to Power Off.


Configure the Use LACP Key and MAC LSB (hex) parameters.

Note: The parameters are configurable only on the 7750 SR, 7750 SR-c12, 7750 SR-12E, 7450 ESS, and 7950 XRS. The NE must also be configured with an IOM 3 MDA or an XMA.

The parameters are displayed and configurable only when both MC LAG members are PBB-capable.


Choose the LAG for the first MC LAG member in the First Site panel.

Note: If you are configuring access dual homing with local switching over PBB tunnels, the L2 access interfaces must be on LAGs that participate in the MC LAG.


Choose the LAG for the second MC LAG member in the Second Site panel.
