I am running 2 span sessions on my Cisco 3750:
monitor session 1 source interface fastethernet 1/0/3
monitor session 1 destination interface fastethernet 1/0/6
monitor session 2 source interface fastethernet 1/0/3 , 1/0/9
monitor session 2 destination interface fastethernet 1/0/48 encapsulation replicate
Now I want to add more source ports to session 2 is this OK to do?
Currently it is monitoring the inside and outside of our firwall VLANS 1/0/3 and 1/0/9, I have a few other VLAN's on the 3750 that I would like to span to port 48 which is where our packet capture server is (Observer).
