Telnet to the switch

You will need the port you want to enable span on. Do show interface to find the port number if you don't know. In following example we are assuming it is port fa 0/2 which will be monitoring port fa 0/5


enable
config term
interface fa 0/2
port monitor fa 0/5
end

what does spanning mean or do?  For example if I span the port that means I can use it to monitor the other ports?

Hi g000se, looking for a deep understanding or a simple breakdown?  Basically, by spanning a port, it allows you to plug in a packet analyzer into one port for example, and see all the traffic to/from the other port that you are specifically monitoring.
