Re: Trouble configuring RSPAN

   SW1 is the has the source port that I want SW2 to be able to view
traffic from. The source port is 1/0/1. I am definitely confused on
the reflector port. What I want to so is monitor traffic from port
1/0/1 to a port on sw2. From reading what the reflector port does it
"SPAN traffic from the sources is copied onto the RSPAN VLAN through
a reflector port and then forwarded over trunk ports that are
carrying the RSPAN VLAN to any RSPAN destination sessions monitoring
the RSPAN VLAN" So I think I need to add the reflector port command
using the same interface 1/0/1 instead of 1/0/10. But the problem is
the switch is not allowing me to add the reflector port command. So
I am sure I am missing something just do not know what it is.

    Thanks,
