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

3. Verify that the port's group capability value matches the value of
the link aggregate. If it does not, do the following:
a. Set the port mode to MANUAL with the following command:
# lanadmin -X -p MANUAL portPPA
b. Set the group capability and mode values with the following
commands:
# lanadmin -X -g value portPPA
# lanadmin -X -p FEC_AUTO portPPA
The ports then negotiate with the link partner (approximately
10 seconds) and join the link aggregate. Repeat this step for
each port you want in the aggregate.
c. Verify that the ports are in the link aggregate with the
lanadmin -x -i command.
d. Save the current configuration either by using SAM or editing
the configuration files.
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, see the steps for Link partner
configured?.
If the status is down, check the cabling from the NIC to the switch and
see the steps for NIC operating?.
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
Complete the following steps:
1. Ensure that the network devices are configured properly on the
local host, using the netstat -i command.
2. Verify that the routing tables on the local host are correct, using
the netstat -r command.
Host known?
NO
YES
If a host is not known, the following message is displayed:
unknown host
Complete the following steps:
1. Verify that the user is trying to reach the remote host using a valid
host name.
2. Verify that the remote host is in another name domain and that
the user specified the full domain name.
3. If your site uses the Domain Name System (DNS) for
name-to-address translation, look in the /etc/nsswitch.conf
file to see if nis is specified as a service for the hosts database
