Re: Cisco 2950 SPAN session

There is a limitation of one active SPAN session on 2950s.

Check the Configuration Guidelines:

Re: Cisco 2950 SPAN session

So is there any workaround for this issue to overcome the limitation

Re: Cisco 2950 SPAN session

You can specify as source ports those two ports and send that traffic to same destination port.

One workaround is by using one SPAN and for the other port you want to monitor, connect a Hub to that port and on the hub connect the device you want to monitor and the box that is going to receive all that traffic (not a very nice workaround by the way).

The other way is by using a Remote SPAN session and send that to another capable RSPAN switch.
