It could also be that on the 3750 the port is showing 100 full but is actually 
half duplex. The switch seems to be very buggy.

The reason is that auto mode uses fast link pulses in order to negotiate speed 
and duplex settings.  If the client is hard coded to 100 full, there are no 
fast link pulses going between the client and switch.  The switch decides that 
nothing else will do in our technologically advanced world besides 'half 
duplex' - leading to duplex mismatch problems beween the workstation and the 
switch.

        Does anyone know the exact reason why if a switchport is set to auto 
and a pc is hard set to anything it negotiates but gets errors?

        They are synonyms in a sense. CAR is a policing method, but one of many.

        Can some one explain when to use policing and when to use CAR. The 
question said policing and the proctor guide used CAR.

        Robert,

        R4 does not need to join. Can you post your config?
        If I get packet loss, I usually join the group manually and test using 
pings, debugging along the way.

               The MRM configuration is pretty straight forward.  Does R4 need 
to join the group 230.230.230.230 for this to have a successful test?  I do a 
mtrace from R2 for 230.230.230.230 and there's nothing there.

               I watched the video solution, I have everything in place as 
instructed, but no love.

               Please help.
               Cheers!
