messages are a subset of the messages APA logs to the nettl log file, but are reworded for readability and understandability.

For information on configuring APA to log status messages to the /var/adm/syslog/ syslog.log file, see “Modifying HP APA Global Parameters” (page 63).

Examples

This section contains sample status messages that might appear in the syslog.log file. In these examples, a link is considered UP:

•If its Operation Status (ifOper) is UP (the link can carry network traffic) and

•If the link is part of a link aggregate and it has successfully negotiated via the protocol with the link partner to become a member of the link aggregate.

A link is considered DOWN:

•Anytime its Operation Status (ifOper) status is DOWN (the link cannot carry network traffic) or

•If the link is part of an automatic link aggregate and the protocol has failed to maintain the membership of the port in the link aggregate.

1The /sbin/init.d/hpapa start command was issued, for example, at system boot time.

2The /sbin/init.d/hpapa stop command was issued.

3Link aggregate (LA) 900 was created with three links 7, 8, and 9.

4 Link 8 is not operational.

5 Link 9 was removed from lan900; for example, by issuing the following command:

#lanadmin -X -d 9 900

6Link 7 and link aggregate 900 are not operational.

7Link aggregate 900 was cleared; for example, by issuing the following command:

# nwmgr -X -c 900

If link aggregate 900 is a failover group, lan900 has a FOG: prefix instead of LA: as shown in the previous example.

For failover groups and Hot-standby mode link aggregates, the current active link is also displayed as in the following example:

Mar 3 08:58:03 hpserver1 vmunix: APA/LM: FOG:lan900 - lan1 is up (lan1 is active)

Mar 3 08:58:03 hpserver1 vmunix: APA/LM: FOG:lan900 is up (lan1 is active)

Mar 3 08:58:03 hpserver1 vmunix: APA/LM: FOG:lan900 - lan2 is up (lan1 is active)

.

Mar 3 08:58:03 hpserver1 vmunix: APA/LM: FOG:lan900 - lan2 now receiving poll \
