to use RSPAN on LAN, I used two Catalyst 3560.
on the first I did the configuration:
monitor session 1 source vlan 1
monitor session 1 destination remote vlan 901
on the second switch I did the config:
monitor session 1 source remote vlan 901
monitor session 1 destination interface FastEthernet 0/23
I can ping the two VLANs as the switch can did the layer 3 functions.
but the first switch cannot support the command "reflector-port".
on the remote port (Fa0/24) I cannot capture the ping between the VLANs, is it due to the reflector-port command??
