1.1 Link Aggregation
Link aggregation aggregates multiple physical Ethernet ports into one logical link, also
called a logical group, to increase reliability and bandwidth. Link aggregation allows you
to increase bandwidth by distributing traffic on the member ports in an aggregation
group. In addition, it provides reliable connectivity because these member ports can
dynamically back up each other.

Consistency Considerations for Ports in an Aggregation
Note:
Note the following when employing link aggregation on an S9500 routing switch:
z
Up to 31 link aggregation groups are supported on a switch.
z
Up to 31 link aggregation groups are supported on XP4B boards. However, ports
on boards of this type cannot be added to aggregation groups.
z
Up to seven link aggregation groups are supported on XP4CA boards. However,
ports on boards of this type cannot be added to aggregation groups.
z
Up to 7 link aggregation groups are supported on boards with their models suffixed
with “C”, “CA”, “CB”, and boards that are of 100 Mbps and of class B.
z
For boards other than the above mentioned, up to 31 link aggregation groups are
supported.
z
To enable load being properly shared among ports in an aggregation group, make
sure the number of the aggregation groups created on a board is not larger than that
the board can accommodate.
