span port destination vlan

Hi All, I need to span a port for sniffer. Src port where server is located : gi 1/11(vlan 100) Dest port where sniffer pc is located: gi 1/25 My question is does the port gi1/25 needs to ve on a specific vlan? Can it be on the same vlan as source port I.r. vlan 100 ? Or should it be on any non-source vlan? thanks in advance

Hi Thomas,Which model of

Hi Thomas,

Which model of switch are you enabling this span?

Anyways you can have the destination port on any vlan depending on what interface you are monitoring. Only problem is that when you are monitoring a  VLAN rather than physical interface you need to be aware that "A destination port that belongs to a source VLAN of any SPAN session is excluded from the source list and is not monitored"

Hope that helps.

Regards

Najaf
