Dynamic Link Aggregation; Configuration Example - Foundry Networks FESX Manual

Dynamic Link Aggregation

Foundry software supports the IEEE 802.3ad standard for link aggregation. This standard describes the Link
Aggregation Control Protocol (LACP), a mechanism for allowing ports on both sides of a redundant link to
configure themselves into a trunk link (aggregate link), without the need for manual configuration of the ports into
trunk groups.
When you enable link aggregation on a group of Foundry ports, the Foundry ports can negotiate with the ports at
the remote ends of the links to establish trunk groups.

Configuration Example

Foundry ports follow the same configuration rules for dynamically created aggregate links as they do for statically
configured trunk groups. See "Trunk Group Rules" on page 10-3 and "Trunk Group Load Sharing" on page 10-6.
Figure 10.5 on page 10-14 shows some examples of valid aggregate links.
