HP UX Auto Port Aggregation (APA) Software manual Configuring a Link Aggregate, Rapid ARP Interval

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-clickNetworking and Communications, and then Auto Port Aggregation. A window like the one in Figure 3-10appears. 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.
