1Connectivity among links in the failover group was lost.

2The link in the failover group started receiving poll packets; it has recovered connectivity.

3 Proactive failover occurred in the failover group.

For detailed log messages, use the NetTL subsystem. See nettl(1M) for more information.

Viewing HP APA Statistics

The link aggregate software keeps a counter for each statistic defined in RFC 1213 MIB II for

32-bit statistics or RFC 2863 for 64-bit statistics. Each counter is set to the negative of the sum of all the physical ports in the link aggregate when it is created. When reporting the value of a statistic, the sum of all the physical ports corresponding statistic counter is added to the link aggregates counter.

For a detailed description of the statistics fields, see RFC 1213 for 32-bit statistics and RFC 2863 for 64-bit statistics.

When a physical port is removed from a link aggregate, each of its statistics is added to the corresponding link aggregate statistic. When a physical port is added to a link aggregate, its current statistics are subtracted from the link aggregates statistics.

NOTE: Cisco's Fast EtherChannel (FEC) packets are not counted in the link aggregate statistics. This is required because the FEC packets never traverse the link aggregate, they only traverse the port.

For the September 2004 release (B.11.23.05) and later of HP APA for HP-UX 11i v2 and the May 2005 release (B.11.11.20) and later of HP APA for HP-UX 11i v1, link aggregates support 64-bit statistics based on the following rules:

Aggregates support the 64-bit MIB (Management Information Base) if all the member links are capable of 64-bit statistics when the aggregate is created.

The 64-bit statistics capability will be downgraded to 32 bits if the aggregate membership changes to include one or more links that are not 64-bit MIB capable. After the aggregate's 64-bit MIB capability is downgraded, it will never be upgraded again for the life of the aggregate.

To display statistics, use the lanadmin -glinkAggPPA command. Example 5-1shows 32-bit MIB statistics returned from this command.
