Unable to remove a port from default VLAN

Question

I am unable to remove a port from my default VLAN.

I've tried:

Switch(config)#interface FastEthernet 0/1
Switch(config-if)#no switchport access vlan 1

It has no errors but when I check it using:

#show vlan brief

Then the port I try to remove is still in vlan 1.

I'm using a Cisco Catalyst 3550.

• Is it possible to remove a port from this VLAN?

Solution

A port must have a VLAN assignment. If you need it to be completely disconnected, set it to a nonexistent VLAN and shut down the port.

interface fa0/1
switchport access vlan 901
no switchport access vlan 1
shutdown

(I'm not sure if the "no" is required. Don't have a switch at my fingers with an open port to test).

That said, shutdown should be sufficient in and of itself.

AFAIK, It cannot not be a member of any VLAN. If you don't want the port in VLAN 1 then you need to assign it to another VLAN. A port cannot be removed from the Native/Default VLAN without being assigned to another VLAN.

Like Joe says...if you don't want it in any vlan then just disable the port, it'll still be a member of VLAN 1 but won't pass traffic.

Depending on the switch you could set the interface to no switchport, but you would need to remember to set it back when configuring as a L2 interface. Also the no switchport access vlan 1 is not required, as you have set it do a different vlan already.
