Disabled:TD code on show interface status on Cisco 9200 switch

[Gustavo Javier Chiarelli]

Hi everyone. Does someone know what is the meaning of "TD" code after the status "disabled" on show interface status?

This is the original output from switch:

#sh int status | i 3/0/2
Gi3/0/2 connected 120 a-full a-100 10/100/1000BaseTX
Gi3/0/20 connected 120 a-half a-100 10/100/1000BaseTX
Gi3/0/21 disabled: TD 120 auto auto 10/100/1000BaseTX

Thank you so much in advance for your help

Gustavo,

I'm not sure what that could be. However, could you share the outputs of the following commands please?

• show interface gi3/0/21
• show interface gi3/0/21 switchport
• show interface status err-disabled

Thank you!

Best regards,
Peter

Gustavo,

It could in fact be an incomplete string from "disabled: TDR running". Is it possible that this interface is currently running the TDR test (from test cable diagnostics)?

Best regards,
Peter

The TDR function has crashed.  

Re-run the TDR test, command: test cable tdr interface Gi3/0/21

If the problem does not fix itself, reboot stack member 3.
