How to Change a VLAN Assignement for an Interface on a Cisco 3750

Question

I'm having some trouble trying to figure out how to Change a VLAN Assignement for an Interface on a Cisco 3750.

I want to change:

!
interface GigabitEthernet1/0/3
switchport access vlan 2
switchport mode access
spanning-tree portfast
!

Into:

!
interface GigabitEthernet1/0/3
 switchport access vlan 3
 switchport mode access
 spanning-tree portfast
!

However I haven't been able to do it successfully.

Any suggestions?

Thanks!

Solution 1

conf t
int g1/0/3
switchport access vlan 3
do wr mem

Solution 2

What have you tried? It should go something like this:

switch# config t
switch(config)#  int gi1/0/3
switch(config-if)#switchport access vlan 3

Then ctrl-z and write mem

it should be 'swichtport access vlan 3' he wants to change from 2 to 3

shouldn't there be a space in there as well? Or am I forgetting IOS quicker than I thought.

If you aren't used to it forgetting what mode you're in is a pretty easy mistake. Especially if you're trying to do a change during a 3am outage.
