First of all you have to create a vlan which will be only used for carrying the RSPAN traffic.Create a dedicated vlan on both the switches:


Conf t

vlan xx

remote-span


On the source switch i.e 6506 you have to run the following command:


conf t


monitor session 1 source < Define the interfaces or source vlan that you want to monitor>

monitor session 1 destination remote vlan xxx


On you destination switch i.e 3750:


conf t


monitor session 1 source vlan xxx

monitor session 1 destination interface fa X/x -> port connected to the monitoring server.
