LAC/LNS Sync Speed

[ar]

Hi.

I am trying to implement auto qos via radius on the LNS depending on the negotiated sync speed for ADSL.

RFC2661 AV type 24/38 seems to be the way to get the sync speed value from the LAC.

Anyone knows how to get this?

anyone familiar?

Hi Allan

Those av-pair should be update by the LAC, we have a feature which provide this function

http://www.cisco.com/en/US/docs/ios/bbdsl/configuration/guide/bba_cfg_ucst_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1055019

Now as you will see this is a manual configuration under a PVC, which potentially would be in my opinion

pretty much the same amount of work than to configure this manually in the radius (qos cisco av-pair)

Potentially if you have a DSLAM acting as LAC that can fill these l2tp av-pair you might be more accurate
