HP Auto Port Aggregation Administrator's Guide for HP-UX 11i v1 and 11i v2 September 2008

Link aggregate
configured?
NO
YES
Verify that the failover group is configured by issuing the following
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).
Failover group
UP?
NO
YES
Verify that the failover group is up by issuing the following command:
# 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.
Correct ports in
failover group?
NO
YES
Verify the ports in the failover group by issuing the following
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 -p portPPA linkAggPPA
If the port is not in LAN_MONITOR mode, possible reasons are:
