HP UX Auto Port Aggregation (APA) Software Set the key value and mode with the following commands

All ports active?

YES

Network reachable?

YES

Host known?

YES

NO

NO

NO

# lanadmin -X-kvalue linkAggPPA

3.Verify that the port's key 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 key value and mode with the following commands:

#lanadmin -X -k value portPPA

#lanadmin -X -p LACP_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.

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?.

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 -icommand.

2.Verify that the routing tables on the local host are correct, using the netstat -rcommand.

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
