Solved: Changing native vlan on running network

a.yazdani · ‎04-26-2015

I want to change the native vlan on running network. a network include 30 switches . there is loop free topology .

unfortunately native vlan is vlan 1 and also management network .

in my test environment :

if I go to a switch and change native vlan from 1 to 100 the stp will Block the link for vlan 1 and i lose my access to the switch and then i should go to other side and change the native vlan to 100.

i just want to know the best practice for this situation.

Thanks !

Correct. As soon as you change it to 100, you will lose access to the devices since vlan 1 is used for management. To shorten the down time, you can create vlan 100 and all the SVIs on all switches ahead of time and than change it form 1 to 100 in a maintenance window.
