Oops sorry I forgot to add the "send traffic to tap" on the second 3550 where your Monitoring device is plugged into
Cisco-3550-2#sh run | i monitor
monitor session 1 source vlan 40, 50 , 60, 991
monitor session 1 destination interface Gi0/10

Then what "I" do is trunk my remote span across its own link on the 3550 (since I have Fiber to burn).
For instance on my 3550 switches......
Cisco3550-1#sh vlan remote-span
Remote SPAN VLANs
------------------------------------------------------------------------------
991
!
Cisco3550-1#sh run | i monitor
monitor session 1 source vlan 10 , 20 , 30 rx
monitor session 1 destination remote vlan 991 reflector-port Gi0/6
!
Cisco3550-1#sh run int gi0/6
Building configuration...
Current configuration : 123 bytes
!
interface GigabitEthernet0/6
description PORT UNUSABLE - DUE TO REFLECTOR RSPAN
switchport mode dynamic desirable
end
interface GigabitEthernet0/5
description - RSPAN UPLINK ONLY
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 991
switchport mode trunk
Cisco3550-1#sh int gi0/6
GigabitEthernet0/6 is up, line protocol is down (monitoring)
Mirrored on the other 3550, there are a couple of different ways to accomplish this but this way works perfect for the solution I needed to solve.
Hope this helps or gets your started!

My RSPAN VLAN is 6
Switch A & Switch B are connected thru ports 1,2,3 & 4, configured as
ether-channel. (trunk port)
port 10 on switch A is the source port
port 10 on switch B is the destination port
When using the refelector-port command on Switch A, which port no. should I
use.
Thanx in advance.
