Add port to VLAN - very basic question

james_pethigal — Thu, 05 Dec 2019 21:34:42 GMT

This a pretty basic questions, but I just want to confirm when I add a port to a VLAN that is already setup... I don’t have to add all the ports already configured?

Seems a stupid questions... but have a bunch of production switches & no test platform.

Have VLAN 75

From Config:

vlan 75 by port

tagged ethe 1/1/20 to 1/1/24 ethe 1/1/48 ethe 1/2/1 to 1/2/2

spanning-tree 802-1w

Want to add ethernet 1/1/37

device(config)# vlan 75

device(config-vlan-75)#tagged ethernet 1/1/37

exit..

Or do I need to included all the ports already setup?

Cheers & thanks for the help!

James

@DeathAndGravity,

You tag ADDITIONAL ports every time.

Cheers,

That is correct. If you tag 1/1/37 to vlan 75, all of the original ports in vlan 75 will stay and you will simply add port 1/1/37 as well. You will see this reflected once you issue a 'show run' or 'show vlan' after you enter the command.

It is enough to add the additional port 1/1/37 like you did.

"device(config-vlan-75)#tagged ethernet 1/1/37"

In order to confirm if the port is added to the VLAN, you can use "Show running-config vlan 75"

Hope that helps,

Hey,
Quick way to see the port membership is to run the following command;
`sh vlan brief ethernet`

SSH@Main-ICX-ST#sh vlan brief ethernet 1/1/7

Port 1/1/7 is a member of 2 VLANs
VLANs 1 3
Untagged VLAN : 1
Tagged VLANs : 3

SSH@Main-ICX-ST#

Hope that helps!

Yes what you did is the right step .Just tagging to the existing VLAN will add the new port into the VLAN. You can verify using "show vlan XX"
