Ports on your Server Switch that grant the initiator of the IT pair access to storage. Using the below setup I see no traffic on the laptop connected to port 17. I am trying to configure a simple SPAN session on a local switch. The restrictions for SPAN are as follows: On each switch, you can configure a maximum of 4 source sessions and 64 RSPAN destination sessions. Mixing ports and VLANs is not possible in the same session, another restriction is that you cannot use a destination port as a source port. Essentially, you can take whatever ports you want and “mirror” them to another, allowing the computer at the other end to receive traffic not originally intended for it (much like how a hub operates). 2(x) .
