can't access switch even on console

[GRANT3779]

Hi,

I believe you are using the wrong interface -

You should be using the local interface address of the switch you are connected to. In your case - examples

sh cdp neigh Gig 2/1/2 det

sh cdp neigh Gig 1/0/1 det

[Mohd Khairul Nizam]

i must be wrong then, i will try again

but what if i sh cdp neig <local interface> detail , but also not showing anything

does it mean the neighbor not turn on cdp neighbor?

CDP is working as that is why you can see the attached neighbours.

Here is some output from my own switch as an example -

UK-CORE-01#sh cdp neighbors

                 Ten 1/5/5         130              S I   WS-C3650- Ten 3/1/4
