SPAN - PORT MIRRORING - CONFIGURATION ON CISCO PACKET TRACER

 SPAN - Switched Port Analyzer 

Allows you to monitor and capture network traffic 😊

Traffic is flowing from source (client) to destination (server)

and we need to monitor and capture the same on the monitoring device -sniffer

 

Once we enable span the initiate the traffic from client to server - a copy of traffic is sent on the switchport connected to sniffer.

Switch(config)#monitor session 1 source interface fa0/1
Switch(config)#monitor session 1 destination interface fa0/3
Switch#sh monitor
