I was checking the VLAN’s on one of my switches. It’s two stacked Catalyst C9200L-24P-4X.

There is one port that I didn’t see on any VLAN, neither is it a trunk. So I went config t, port, switchport access VLAN 2, then I check the VLANs again and the port still doesn’t appear on any VLAN. The switch takes the command, meaning there are not error messages.

Any ideas?

Thanks

Not in config t mode, but at the # type this command. → interface “your port #info” swithport, then hit enter and review the displayed information. You should see the information regarding the assigned vlan.

at the # prompt, interface is an unrecognized command

Is the port shut down? It might not appear in that output if it is shut down.

Your port information is specific to your device. Just replace it with the port that you are trying to configure.

I hope that helps, if not hit me up on a DM and I can help walk you through it. Cheers!

The port is assigned to VLAN 9, but VLAN 9 doesn’t show the port

You’re missing a command

default int

I don’t know what you mean that I’m missing a command. I ran the command you suggested (show int xxx switchport) at the # prompt. Now you are showing me a different one (do sh run int xxx) at the config-if prompt, but that comes back as invalid command:

Maybe we have different iOS versions?

These are do subcommands

I don’t know what you mean.

Exit configuration mode to use the show commands.

The output from ‘sh int gi1/0/10 switchport’ shows that the port IS in trunk mode.

try again the “switchport mode access” on the interface.
If not as agenglercain suggests default the port and reconfigure it.

conf t
default int gi 1/0/10
int gi 1/0/10
switchport mode access
switchport access vlan 9
no shut
end

Good morning, I want to apologize for my informtion. I over looked the fact that you were using IOS XE. I the command that you are missing is “switchport mode access” while you are in configuration mode within the specific interface config.

I have no idea what happened other than me being brain fried yesterday because I listed the trunks and this int was not there. I also ran the switchport mode access command twice. And the screenshot that I posted shows that it was on VLAN 9. Yet, today I listed the trunks again and lo and behold, I saw it. And now I ran switchport mode access again and this time “it took” and the port is now in the VLAN that I wanted. So either yesterday I ran all the commands wrong and saw all the results wrong, or I don’t know what the heck happened.

Nonetheless, I’m good now.

Thanks!

No worries. I did run that command yesterday, twice. One of the few things that I’ve been doing for decades is assigning ports to VLANs on Cisco switches. Since the Catalyst 1900!
