Local port mirroring works but Remote port mirroring does not

[WTIB54]

Hello,

I am struggling trying to set up a remote mirroring port on a procurve switch but I am unable to get it working.

I’ve followed the configuration manual of how to set it up from CLI, and also I’ve tried using PCMv4 but the traffic is not being seen on selected port.

However Local mirroring works as expected for the "same ports".

I am using Procurve switches 5406zl as source and destination, and any other switch between is also a 5406zl switch.

I don’t know how to troubleshoot if the source switch is even sending the mirrored traffic to the destination switch.

Any help would be appreciated.

Thanks.
