Solved: Changing a port from a vlan to another

waguilar71 · ‎04-19-2012

Hi everyone,

I have a 3560 switch with the following ports config

interface FastEthernet0/43
description : Link to PC + ShoreTel IP Phone
switchport access vlan 120
switchport trunk encapsulation dot1q
switchport trunk native vlan 120
switchport mode access
service-policy input VOICE

interface FastEthernet0/25
description : Link to PC + ShoreTel IP Phone
switchport trunk encapsulation dot1q
switchport mode trunk
service-policy input VOICE

interface FastEthernet0/28
description : Link to PC + ShoreTel IP Phone
switchport trunk encapsulation dot1q
switchport mode access
service-policy input VOICE

interface FastEthernet0/46
description : Link to PC + ShoreTel IP Phone
switchport trunk encapsulation dot1q
switchport mode trunk
service-policy input VOICE

I would like to use theses ports on a different vlan to connect 4 pc's to them. Can I just remove them from the vlan, remove the trunk switchport and set up on the vlan i want them on with no trunking?

Thanks

Wilfredo

Quick answer is yes. Just do the following for each port

conf t

default interface Fx/x

interf fx/x

switchport

switchport access vlan X

switchport host

Here is how I do it when I re-provision ports

This part sets the interfaces to default config.

config t

default int fa0/43

default int fa0/25

default int fa0/28

default int fa0/46

Now you can configure the ports

interface faX/X <---- substitute the X/X with the port number

description PC

switchport

switchport mode access

switchport access vlan XXX <------ substitute the XXX with the Vlan you want to assign

spanning-tree portfast

no shut

then save the configuration by issuing the command write mem

Hope this helps.

Thanks for your reply Grant, what do you mean by default interface

glen.grant · ‎04-19-2012

Default interface fx/x will set that port back to factory defaults without having to do a "no" command for each line in the port config.

Thanks guys,

The instructions worked that both of you provided. One more detailed than the other but they worked. I did use the command

spanning-tree host and it setup the port at portfast by default. I will be making the connections tonight of the pc's and all should be well.
