Brian,
I don't understand. How are you going to monitor f0/3 on switch A and send
to f0/3 on switch B. If you only do the configuration on one switch.
Wouldn't that just be considered SPAN?
This is what I'm thinking a config would look like... I apologize if my
syntax is off I'm doing it from memory:
SwA#
Vlan 100
Remote-span
!
monitor session 1 source int f0/3
monitor session 1 source int f0/2
monitor session 1 destination remote vlan 100 reflect f0/24
!
SwB#
Monitor session 1 source remote vlan 100
Monitor session 1 destination interface f0/3
I mean yes, there's no question you can configure only one switch. But if
you want a source to get the data you have to configure the switch.
I guess you can configure this all on one switch - but why go through all
this extra effort if you can just use span.
Thanks,
Joe

RSPAN is an attribute that is propagated via VTP. Therefore
assuming you are running VTP you only need to define it on a VTP server
in the network.
BTW Tim, it's not a "gotcha", but instead just a requirement of
the configuration ;)
