This should get you started:

Please see this link,
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/31sg/configuration/guide/span.html
Step 1.
Switch(config)# vlan 901
Switch(config-vlan)# remote span
Switch(config-vlan)# end
Step 2. Assuming gigabitethernet0/1 is the port that you want to sniff
Switch(config)# monitor session 1 source interface gigabitethernet0/1 both
Switch(config)# monitor session 1 destination remote vlan 901
Switch(config)# end
To get the information that is flowing to the remote VLAN (on our case 901), this needs to be done on the switch where you have the device that will receive the RSPAN traffic.
Step 3.
Switch(config)# vlan 901
Switch(config-vlan)# remote span
Switch(config-vlan)# end
Step 4. Assuming gig0/5 is the port where you have the PC/server with the shiff capture software.
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface gig0/5
Switch(config)# end
All the switches on the path between initial switch and ending switch should have the remote VLAN, follow step 3 , also VTP pruning should be disable in order to allow the VLAN to be enabled and present on all the switches.
