HP Auto Port Aggregation Administrator's Guide for HP-UX 11i v1 and 11i v2 September 2008
# lanadmin -X -d -portPPA linkAggPPA
If there are ports you wanted in the link aggregate that are not members
of the link aggregate, do the following:
1. If FEC or LACP is enabled on the port, stop autonegotiation with
the following command:
# lanadmin -X -p portPPA MANUAL linkAggPPA
2. Verify the type, speed (including duplex), and MTU size of each
port you want with the following command:
# lanadmin -g portPPA
All ports must have the same values. If they do not, make any
changes as necessary on the server and the switch.
3. Add each port to the aggregate with the following command:
# lanadmin -X -a portPPA linkAggPPA
where portPPA can be a list of multiple ports numbers separated
by a space.
NOTE: Use SAM or edit the configuration files to make the
configuration changes permanent.
4. Check if there is an IP address or a VLAN on the port.
All ports active?
NO
YES
Verify the active ports in the link aggregate by issuing the following
command:
# lanadmin -x -i linkAggPPA
The Active Ports PPA # field lists the active ports.
If there are ports in the Port(s) not ready field, verify the port's
operation status by issuing the following command:
# lanadmin -g portPPA
If the Operation Status is up, check the speed (including duplex) and
MTU for the port and another active port in the link aggregate with
the following command:
# lanadmin -s -m portPPA
If they do not match, correct the settings on the server and the switch.
See the steps for Link partner configured?. If they match, reset
the port.
If the status is DOWN, check the cabling from the NIC to the switch
and see the steps for NIC operating?.
On the switch, verify that all ports you expect to be in the link aggregate
are in the same MANUAL trunk.
NOTE: If you are using the HOT_STANDBY load distribution
algorithm, be sure the switch side port is not in any trunk.
Network
reachable?
NO
YES
If a remote host's network is not reachable, the following message is
displayed in response to the ping command:
network is unreachable
