When configuring SPAN , if I understand it involves just one switch . Correct ?
(config)#monitor session 1 source interface fa0/20
(config)#monitor session 1 destination interface fa0/25
** in case fa0/20 and fa0/25 are in separate VLANs, would the packets capturing work?
** I also would like to know when configuring RSPAN to capture traffic from source port or source Vlan on Switch1 and Destination port or Vlan on Switch 25, when there is a chain of switches between Swith1 and Switch 25, do we need to configure RSPAN on all 25 switches ?
How can this be configured ?
