Link aggregate configured?

YES

Failover group UP?

YES

Correct ports in failover group?

YES

Verify that the failover group is configured by issuing the following NO command:

# lanadmin -x -i linkAggPPA

If the failover group is not configured (Link Aggregation Mode is MODE_UNDEFINED), edit the configuration files to configure it. For more information, see “Editing Configuration Files for Failover Groups” (page 107).

Verify that the failover group is up by issuing the following command:

NO	# lanadmin -g linkAggPPA

If the failover group (LAN_MONITOR mode) is enabled, the Operation Status is up.

If the Operation Status is down, do the following:

1.Check that all ports in the failover group are connected to the switch.

2.Verify that the link partner is configured for no trunking. Make any changes, if necessary, and wait 10 seconds. Then, verify that the failover group is up.

Verify the ports in the failover group by issuing the following NO command:

# lanadmin -x -i linkAggPPA

The Active Port PPA #, Port(s) ready, and Port(s) not ready fields show the ports that compose the failover group.

If the failover group contains ports that you do not want, edit the configuration files and delete the ports from the failover group. For more information, see “Editing Configuration Files for Failover Groups” (page 107).

If any ports you wanted in the failover group are members of another link aggregate, delete the ports in the other aggregate by editing the configuration files and removing the ports from the link aggregate.

For more information, see “Editing Configuration Files for Failover Groups” (page 107).

If there are ports in the failover group that are not members of the failover group, verify the type, speed, duplex mode, MTU size, and checksum offload capability of each port you want with the following command:

#lanadmin -x -g portPPA

All ports must have the same values. To change a port attribute, edit the configuration file and make any changes. For more information, see “Editing Configuration Files for Failover Groups” (page 107).

Verify that the port is in LAN_MONITOR mode with the following command:

#lanadmin -x-pportPPA linkAggPPA

If the port is not in LAN_MONITOR mode, possible reasons are:
