show vsf trunk-designated-forwarder

Syntax

show vsf trunk-designated-forwarder

Description

Show the designated forwarders for each trunk.

For each trunk, only one member of the trunk will forward L2 flood traffic (unknown destination, Broadcast & Multicast). Use the show vsf trunk-designated-forwarder command to know which member will forward flood frames for a given trunk.

For known unicast traffic, trunks will always forward using local member links when possible and traffic will cross the VSF links to the other member only when local links of a trunk are down.
