Solved: Cisco Voice VLAN and disable data vlan.

Darshan Argekar · ‎03-04-2015

The existing running setup having Voice VLAN configured with data vlan 2012 and Voice vlan 2046. Now we want to disable data vlan to avoide all data activitiess and to have only Voice Vlan enabled on the port. To accomplish this planning to remove command " Switchport access vlan 2012" with "Switchport access vlan 2012"

The ask here is once we disable will it cause any impact for voice service ? Voice should work as normal.

Existing Configuration.

Sw1(config-if)#switchport mode access

Sw1(config-if)#Switchport access vlan 2012

Sw1(config-if)#switchport voice vlan 2046

To remove that vlan from your port you will need to issue the command:

config t

int XXXX(this is the interface that you will be connecting to)

shutdown(to bring the port down to make changes)

no switchport access vlan 2012 (to take out the access vlan)

no shutdown (to open the port back up after all changes have been made)

If you remove this only the voice vlan will be able to pass traffic on the port that you in currently.

As long as the voice vlan is still on that port then voice traffic will be able to come out of that port assuming all other configuration upstream is correct
