Local SPAN configuration, go to this link for config example..

http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_12c_ea1/configuration/guide/swspan.html#wp1036829

Basic script.

Switch(config)# monitor session 1 source interface fastEthernet0/9 both

Switch(config)# monitor session 1 destination interface fastEthernet0/5 ( This is where sniffer is connected )

to see active monitor sessions issue " show monitor "

to kill the monitor issue " no monitor session 1 "
