Hello everyone,

We have Juniper ERX as BRAS for ADSL, its GigE interface is on an old Cisco 3508 switch with an old IOS, its gateway to the internet is a 7609, our transit internet links terminate on GigaE, Flexwan on the 7600

The links are now almost always fully utilized, we want to do some QoS to cap our ADSL downstream, to give room for the Corp. customers traffic to flow without pain.

I'm here to collect ideas, comments, advises and experiences for such situations.

Our humble approach was to collect some p2p ports and police traffic to these ports, but the traffic wasnt much, one other thing is rate-limiting per ADSL customers IPs, but that wasnt supported by management, so we thought of matching ADSL www traffic and doing exceed action is transmit, and police other IP traffic.

Doing so on the ERX wasnt a nice experience, so we're trying to do it on the cisco.
