VLANs Traversing a Network

By daxm (December 2nd, 2009)

A quick note on VLANs traversing trunk links between switches:

Even though VLANs 1-4094 are allowed, by default, across a trunk link the remote switch will NOT process the encapsulated frame if that switch is not made aware of the incoming VLAN tag.

Therefore, ALL switches within a broadcast domain need to be made aware of ALL VLANs that will/can traverse their trunked ports.
