IOS prbs cable diagnostics

[Usjes0000]

Hi,

I have been trying to use the IOS 'prbs' cable diagnostics on a Catalyst 2960S switch but I can't figure out the correct syntax. I have tried a number of things:

test cable-diagnostics prbs start ?

  interface  Specify an interface for test

This is indicating that the 'start' must be followed by 'interface' indicating the interface to be tested so I tried:

Switch#test cable-diagnostics prbs start int Gi0/1

                                                                ^

% Invalid input detected at '^' marker.

I simply copied the 'int Gi0/1' syntax from the 'test cable-diagnostics tdr' command. But clearly it is not correct, so can anyone tell me what the correct syntax is to test the 'prbs' cable-diagnostics on port 1 ?

Thanks,

Usjes.

The PRBS test can only be executed for TenG interfaces:

For example,

SWITCH# test cable-diagnostics prbs start interface TenGigabitEthernet ?

<1-9> TenGigabitEthernet interface number

PRBS is for fibre optic.  Not yet supported.

If you want copper, then try this.
