Have a look at the CISCO-VPDN-MGMT-MIB which might provide what you
We graphed per-user utilization stats for a somewhat special VPDN dialup
solution at one time with this MIB. This was just a dialup service
coming in from AS5300s and L2TP-tunneled to a 7206VXR LNS. We don't use
any PPPoE at all, so I don't know if this will work for your environment
You should be able to see the username associated with a session on the
LNS walking cvpdnSessionAttrUserName, and various associated counters
are available (cvpdnSessionAttrBytesIn/Out,
We used a perl script to fetch this data and store the results in
per-username RRDs, but I guess you could be able to hack this into
But again - never done this with PPPoE, so ymmv.
