Unable to clear VLAN on port

TexasMirty@gmail.com · Guest

I have set up a VLAN on a Cisco Catalyst 3560 switch. I want ports
20-23 in the VLAN. However, the ports are showing up as belonging to
two VLANs. I want them to be on just one VLAN.

The CLI commands:

no switchport mode access
no switchport access vlan 100

is not clearing the association to VLAN_VOICE (Vlan 100) from the
ports.

The "show vlan" command shows this. You can see my VLAN conf20 is set
up, but the ports in that VLAN are also in the VOICE_VLAN .

did you config the port usinbg the switchport voice vlan command

if so then use "no switchport voice vlan" command to remove

MdV · Guest

you can try this to default the ports

default interface fa0/20 - 23

this command will default the ports to its original settings.

Thank you for responding! I'm new at this and have been thrown into the
deep end of the pool. I appreciate the help very much.

I set the ports back to default and that did fix the problem.
