UDLD on CX Gigastack

[g.schaarup]

Is it possible to run UDLD on a CX Gigastack port ?

Hello,

I think it does. Just make sure that you run udld aggressive, this is for copper ports.

Hi,

Could you provide some more information to see

what might be the problem:

1) what type of switch are you using

2) what IOS version are you running

3) what exactly is the problem you are seeing.

Problems with the operation, or just no CLI

to configure UDLD

Thanks,

/Michel

Hi Gert,

if you enable UDLD globally it only get's enabled

on fiber ports. Try enabling it on the gi 0/2 port

as well as this is a copper port

Thanks
