Created vlan but no PVID is assigned to interface?

unknown

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.

unknown

thx for the reply. dont have access to the switch at the moment. here s a copy of the config tho. also its SW: Version 08.0.80dT213 - so no dual-mode. both tagged and untagged as needed.

show run

Got it. So are you seeing pvid 1, correct? This would be expected as that column is showing you the untagged vlan more or less. All of your tagged ports there still exist in vlan 1 untagged since it is the default vlan. The 'show vlan' would confirm that I believe.

unknown

the problem is i can't ping anything on either vlan. can't ping the router 1/1/1 can't ping the voice server in port 1/1/2. the arp table shows nothing. I figured the PVID not showing the vlan member meant something was wrong with config or switch.
