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 -g linkAggPPA command. Example 5-1 shows 32-bit MIB statistics returned from this
command.
