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
 
1 

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

2 

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

3 

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

4 

Click on the Associated Groups tab.

5 

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

6 

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.

7 

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.

8 

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.

9 

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

10 

Save your changes and close the forms.
