I've created a vlan and assigned an interface to that vlan as well as ve and assigned it an ip. however when i show interface brief it shows the pvid as vlan 1. Shouldn't it automatically assign the vlan id of the untagged port assigned to it?

Hey John, 

Can you provide the following output and note the port:

show run
show vlan 
show vlan brief

Did you apply that interface as tagged or untagged? Depending on the code level you are on, even if you tag a port to a vlan, it will still exist in the default vlan as untagged (think native vlan or our old method known as dual-mode). This allows untagged traffic to pass on the interface.

Hey John,

I don't think the PVID display is a problem or unexpected based on your configuration.

Should all those ports be tagged or untagged?
Are we learning mac addresses?

It would probably be a lot easier to open a support case and have one of our engineers assist live.

vlan 100 should be untagged, vlan 101 should be untagged on 1/1/2 and tagged on 1/1/3 to 1/1/12. dont have support for the switch. this is a simple 2 vlan voice and data configuration. Not sure why this config isn't working seems like it should. yes its learning the mac's.

Hey John, 

You may just be learning macs in vlan 1 based on the configuration you sent in. You may need to remove the tagged ports in the data vlan and make then untagged (tagged for voice, untagged for data).

if I run the command to untag it says the port is already an untagged member. I don't know...

It looks like the ports are tagged in vlan 100. I don't see them untagged anywhere else. You would need to do something like this:

conf t
vlan 100
no tagged eth <phone ports>
untagged eth <phone ports>
