Port mirroring on FEX (Catalyst 6880x)

[g.ska]

Hello everybody,

I try to configure "port mirroring" on a Catalyst 6880x with FEX (6800ia) but it doesn't work. I don't receive data in wireshark. Could you tell me if something is missing in my configuration:

monitor session 1 source interface gi108/1/0/13 both (source)

monitor session 1 destination interface gi101/1/0/25 (laptop with wireshark)

I don't know if I have to configure SPAN or RSPAN with FEX on catalyst switch. Can you help me?

Thanks in advance.

Best regards,

Gregory.

Hello Gregory,

I belive FEX port cannot be configured as a SPAN destination. Switch port can be configured as a SPAN destination

Check out the below link for information.

Hope it Helps..

Hi Ganesh,

Thank you for the answer. Do you know if it's the same behavior with FEX in Catalyst or Nexus switches?

Best regards,

Greg.

Hello Gregory,

I would like to answer this , the behaviour is stil lthe same for the Nexus switches. You cannot have fex port as a SPAN destination.
