What is the purpose of having VLAN 666 (This is a VLAN that does not have an ip address) being used for Vacant and Unused ports? Why not just shutdown the ports that are not being used?
I was received a recommendation from a CCIE consultant to use VLAN 666 as a vacant and unused port VLan and assign all vacant ports to it. I dont understand the benefit of it.
Here is an example of what he wanted me to configure as VLAN 666
interface vlan 666
description Penalty Box vlan, Assign all unused/vacant ports here
no ip address
no ip redirects
no ip proxy-arp
no ip mask-reply
no ip directed broadcast
no ip forward-protocol (etc)
Thank you for all responses to this post!!!
