access port - tagged or untagged?

david_wheeler_e — Tue, 23 Jun 2020 15:57:47 GMT

I want to set one port on my switch to vlan 20. In doing so I am hoping the port will acquire an ip address from my vlan 20 dhcp scope. It works fine on a cisco switch port as an access port.

My understanding is I need to set the port to untagged on vlan 20 but I get an error that the port in a dual-mode port. What do I need to do to make this port get only vlan 20? thanks.

Hi Dave.

This Is hapening because the Port Is already Tagged in a VLAN AND Is also in dual mode.

Go to the interface configuration and do no dual-mode.

After that you can go to the VLAN configuration and add the Port as untagged.

Hi Dave,

That means that the Port 3/1/1 Is Tagged in a VLAN. You cant untag a Port un More than one VLAN so first you need to remove the Port from the VLAN.

With a show VLAN, you can check which porta are assigned to which vlans, Tagged or untagged.

Go to that VLAN and do "no tag eth 3/1/1" after it is removed. You can add it as untagged un the required VLAN.

I got it to work with your help of course! I did a sho vlan brief e 3/1/1 and it showed that it was still in the voice vlan 200. Once I removed it from 200 and remove the dual-mode, I was able to "untagged" the port in vlan 20. Thanks for your help.
