2960 port is disabled

[GuidoBarendse88]

Hello,

In the web-interface of the switch port Fe0/4 shows up orange an the description says that it is disabled.

When I use the show interface fa0/4 command it says the port is up

Which one is the correct one?

I would always trust the actual CLI on the switch. However the easiest solution is what is connected to fa0/4 and is it working ?

What VLAN is the port configured on? Is that VLAN active and created?

Hi,

The indication that port is disabled in Cisco Device Manager ("web-interface") is very often due to the spanning-tree port blocking status. In this case you can still see "interface up, line protocol up (connected)" status in the "sh int" command output. You can easily check if this is your case via the "sh spanning-tree" command.

Best regards,

Antonin

Hi,

you can issue show spanning-tree interface to see the stp status for all vlans.

Hope this helps

Cheers

Does this mean there is no network connection on the 0/4 port? or that STP is nog working on this port?

[amikat]

Hi,

If there is nothing connected to Fa0/4 port the interface should not stay at "line protocol up (connected)" status. Also LRN (learning) is STP only transition state and as such the interface should not stay at this one. Would you mind to post your interface Fa0/4 and STP configuration?

Best regards,

Antonin

I allready had edited my post by saying there is something connected on the port. It is an camera.

[Guilherme Batistelli]

shutdown / no shutdown  ?

[Somasundaram Jayaraman · Accepted solution]

Hi,

Make that interface as port-fast and check

Thanks

This works perfect.

What is the command the return to the original state?

Is it: no spanning-tree portfast?
