HP Auto Port Aggregation Administrator's Guide HP-UX 11i v3 (766140-001, March 2014)

Verifying the configuration
The APA main page displays all configured link aggregates and failover groups, and any available
ports on the system. Alternatively, you can view all configured link aggregates by issuing the
following command:
# nwmgr -S apa
What happens during start up?
During the system boot-up, the following events occur:
1. HP APA software initializes
All the internal housekeeping initialization (for example, allocation of memory) for the software
is done. During this step, the default values are assigned for all the properties on each port
and link aggregate.
2. hp_apaportconf file is processed
Contains customization variables for each physical port. The features that can be set on each
port are Group Capability, Port Priority, and Configuration Mode. If no value is specified for
a given feature for a given port, the software assumes a default value for the same. The port's
mode is set at this stage.
3. hp_apaconf file is processed
The /etc/rc.config.d/hp_apaconf file contains customization variables for each link
aggregate. The features that can be set on each link aggregate are Load Balancing mode,
Hot Standby mode, and ports in a Manual link aggregate. The last feature allows manual
configuration of a link aggregate with the port(s) specified.
4. HP APA software starts
Cisco's FEC or IEEE 802.3ad LACP protocol is started on the ports that have been marked as
such. No action is taken for the ports that have Cisco's FEC or IEEE 802.3ad LACP turned
off.
5. LAN Monitor ASCII file is processed
Process /etc/lanmon/lanconfig.ascii to create failover groups. If this file has not been
created, no action is taken.
After the system is up and running, you can distinguish a link aggregate from a normal
(unaggregated) port by running the nwmgr command. For more information, see Chapter 5
(page 41).
