implement a successful workaround, so I do have recording operational right now.
I just don't like leaving things like this unresolved! Also, IPCCx 4.x
upgrade is in the planning stages, but I'm just trying to figure this out
because it seems like the switch is not operating as it should. I admit it could
be my config, but it's only two lines!</FONT></SPAN></DIV>

the transmit packets, resulting in only recording one side of the

and NO packets were mirrored whatsoever. From what I can tell, it seems I
can't SPAN packets coming from the CMM.</SPAN></FONT><o:p></o:p></P>
