RE: Problem traffic shaping individual PPPoE sessionson a Cisco 2621 XM running c2600-telco-mz.123-7.T3.bin
|
|
We managed to get rate-shaping working using RADIUS....
We're terminating PPPoE on a 7301. We solved this by having the radius server pass back rate-limit attributes in the reply. Applying templates won't work. I spent quite a bit of time getting this right :-)
e.g. Cisco-AVpair = "lcp:interface-config=traffic-shape rate 200000"
If you look back through the threads on this list, you'll see a previous thread on PPPoE
Several people here were instrumental in getting this working
Cheers,
Gordon
