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

Rapid ARP Interval
The number of microseconds between rapid gratuitous ARP messages. The range of valid values
is 1000000–4000000, inclusive (1 second to 4 seconds). The default value is 1000000 (1 second).
Specify a whole number of seconds because the value you specify is rounded up to the next
whole number of seconds. The value must be a valid integer. The rapid ARP interval multiplied
by the rapid ARP count must be less than or equal to 60 seconds.
Rapid ARP Count
The number of gratuitous ARP packets sent rapidly. The valid range is 5–60, inclusive. The
default value is 10. The value must be a valid integer. The rapid ARP interval multiplied by the
rapid ARP count must be less than or equal to 60 seconds.
Configuring a Link Aggregate
This section shows how to configure the following using SAM:
• FEC_AUTO mode link aggregates
• MANUAL mode link aggregates
For information on configuring link aggregates by editing configuration files, see “Editing
Configuration Files for Link Aggregates” (page 105).
Configuring an FEC_AUTO Mode Link Aggregate
When configuring an automatic link aggregate (FEC_AUTO or LACP_AUTO) using SAM, you
configure the link aggregation characteristics first, followed by the port's modes and characteristics.
NOTE: Although this example shows how to configure an FEC_AUTO mode link aggregate,
you can use these steps to configure an LACP_AUTO link aggregate. Substitute LACP_AUTO
for FEC_AUTO, and key for group_capability.
Complete the following steps:
1. Log in as superuser.
2. Enter sam at the HP-UX system prompt.
3. Double-click Networking and Communications, and then Auto Port Aggregation. A
window like the one in Figure 3-10 appears. The Networking and Communications screen's
List pull-down menu displays one of the following:
• Link Aggregates supported by HP APA. This is the list of all available link aggregates
in the system.
• Network Physical Ports that Support HP APA. This is the list of all physical ports in
the system that support HP APA.
