Solving Link Aggregate Problems (MANUAL Mode)
Link partner
configured?
NO
YES
Do the following:
• Verify that the switch is configured correctly with the appropriate
ports enabled. See the appropriate switch documentation to
determine if the switch ports connected to the server are
configured correctly for manual link aggregation (trunking) and
do not run FEC or LACP.
Link aggregate
configured?
NO
YES
Verify that the link aggregate is configured by issuing the lanscan
command. Link aggregate names begin with LinkAgg.
If the link aggregate is not configured, use the SAM to configure it. See
“Configuring a Link Aggregate” (page 36) for more information.
Link aggregate
enabled?
NO
YES
Verify that the link aggregate is enabled by issuing the following
command:
# lanadmin -x -i linkAggPPA
If the aggregate is enabled, the Link Aggregation Mode is MANUAL.
If the aggregate is not enabled, do the following:
1. Check the cabling between the NIC and the switch.
2. Verify that the link partner is configured to run manual trunks.
Make any changes, if necessary. Then, verify that the link aggregate
is enabled.
3. Verify that all ports in the aggregate are set to the same MANUAL
mode by using the following command for each port:
# lanadmin -x -p portPPA linkAggPPA
If they are not, use the SAM to modify the link aggregate.
Correct ports in
link aggregate?
NO
YES
Verify the ports in the link aggregate by issuing the following
command:
# lanadmin -x -i linkAggPPA
The Active Ports PPA # entry shows the ports that compose the
link aggregate.
If the link aggregate contains ports that you do not want in the
aggregate, delete the ports by issuing the following command:
# lanadmin -X -d portPPA linkAggPPA
where portPPA can be a list of multiple ports numbers separated by
a space.
If any ports you wanted in the link aggregate are members of another
link aggregate, delete the ports in the other aggregate by issuing the
following command:
