Switched Port Analyzer (SPAN)

The analyzer is locally connected to the SPAN destination interface of the SLX device. Unlike a hub, which broadcasts any incoming traffic to all ports, the SLX device forwards traffic accordingly. If you want to snoop on the traffic that passes through a specific port, use port mirroring to copy the packets to a port connected to the analyzer.

You use the monitor session command to enable a SPAN session. With this command, you can set the packet source, the packet destination, and the packet direction (egress, ingress, or both).
