Actually what happens is this, let's say 2 MPP users connect to the system
both dialing the separate chassis. The first client connects, and his second
channel is connected via USR's MPIP (Multilink PPP Interchassis Protocol).
For the second channel, the authentication request comes from the 2nd chassis
but the accounting start record comes from the first chassis reporting it as
Port 6000. Now when the second person connects to the 2 chassis, the second
channel will report the same and what will occur within Radius is that the
first client's second channel lost connection (but his second channel is still
up) and starts the record for the second client's second channel on port 6000.
This seems like a bug with the MPIP Radius interaction. I am currently
talking with USR on this issue.
