span port equivalent on catalyst 3548

[phalin]

Hello ..

Is there an equivalent command (from cli) to configure span ports? I am familiar with the higher end cat switches (ie "set span" on the 65xx series) but have not been able to find a similar function on the 3548.

Thanks.

interface SuperFastInterface0/1

port monitor OtherInterface 0/2

where SuperFastInterface 0/1 is the interface which will be the interface where you send all your duplicate traffic; the interface to which you connect your "listening" equipment

OtherInterface 0/2 is the interface from which you wish to copy traffic.

hope it makes sense ;)
