Configuring VTP Snooping
VTP is a Layer 2 protocol developed by Cisco to maintain VLAN
configuration consistency among its switches. this protocol only
runs over trunk ports that have enabled either Cisco ISL or IEEE
802.1Q tagging. VTP Snooping allows a Cajun switch to synchronize
its VLAN configuration with that of a Cisco switch running VTP in
the same network. VLAN additions, deletions, and name changes
made on the network’s Cisco VTP server will be automatically
updated on Cajun switches that have VTP Snooping enabled and
have connectivity to the Cisco VTP server. VLAN changes made on a
Cajun switch are not automatically updated on any other switch.
* Note:
VTP Snooping is enabled by default. You would only
need to change VTP Snooping port settings if you
wanted to disable its ability to learn VLAN changes on
the network’s Cisco VTP server.
