Destination port not responding over SPAN

[Arshad Khan]

HI,

i have configured SPAN over cisco 2960 to monitor source port traffic but after configuration i dont able to get response from destination port  as my NMS is attached on destination port so i lost its web interface.

Configuration is as under.

monitor session 1 source interface gigabitEthernet0/5  (Source Port on Vlan 100)

monitor session 1 destination interface gigabitEthernet0/1 (Destination Port on Vlan 200)

Kindly advice in this regard.

Regards,

Arshad Ahmed

Hello Arshad Ahmed,

I suppose that you want the SPAN destination port to continue communicating according to its own configuration.

In that case, the monitor session 1 destination command has to be modified to also allow ingress traffic on the destination port to be processed, as follows:

monitor session 1 destination interface gigabitEthernet0/1 ingress untagged vlan 200

Best regards,

Peter

Hello Peter,

I have also issued said command but unable to ping / communicate with my NMS (connected to destination port).
