2960S trunking issue after IOS upgrade.

[richard klein]

Hi,

I have done this a few times and am missing something but cant figure out what it is. I think I should have set Gi2/0/1 with trunk for Vlan 1 & 50 - it shows no trunk at all.

Any ideas what i am doing wrong?

Thanks, Rich

Port 1 will have both Vlan 1 & Vlan 50 trunking - Port 14 says all Vlan enabled but Vlan 50 doesnt actually work.

I have a Ubi wifi access point looking for Vlan 1 & 50 - it works on Port 1, but not port 14.

In the past prior to this upgrade it would work with the top commands.

What am I doing wrong?

Thanks,
Rich

Try this

config t

interfaces gi2/0/14

switchport access vlan 50

!

end

test it

[richard klein]

Wouldnt that make the port only access Vlan50?  

Should I do a factory reset on the switch (how do i do that?)

[balaji.bandi]

If you looking to port to be in Access vlan that command i gave you to work ?

But you looking for trunk ? as suggested on other post can you post full configuration.

[Leo Laohoo]

The port is down. Is anything connected to it?

[Leo Laohoo]

Post the complete output to the command "sh interface G1/0/14 controll".
