Cisco 2960-S Switch

[Adrian Castro]

Hi Guys,

The switch port of the 2960-S switch turns amber after accidentally connected the cable to the uplink port, I already perform shut and no shut command and still the port was still amber, what do I need to do? Please help. Thanks!

BTW here's the config FYR:

interface GigabitEthernet1/0/33
 switchport access vlan 38
 switchport mode access
 switchport voice vlan 16
 mls qos trust cos
 spanning-tree portfast
 spanning-tree bpduguard enable
 spanning-tree guard root

Interface status:

Bad cable.

Do this:  

1.  Command:  test cable tdr interface GigabitEthernet1/0/33;

2.  Wait for about 5 to 7 seconds; 

3.  Command:  sh cable tdr interface GigabitEthernet1/0/33; and

4.  Post the output to #3.

Thanks, I'll try to do this. 

Btw. There is no cable on the switch port when I perform the interface status and even without  cable it was still amber, I didn't know why reliability becomes like that.

Did you tried rebooting the switch?

This means you've got a line fault.

605 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 

And this confirms you've got a line fault. 

Last input never, output 5d03h, output hang never

This means the last traffic sent by the switch was 5 days ago. 

   0 packets input, 155098 bytes, 0 no buffer
467 packets output, 50189 bytes, 0 underruns

This tells me of a short burst of traffic before the interface went down. 

Don't worry about the amber LED.  Connect a working client with a known working cable and the LED should turn to green.
