Before I start, let me just ask if there are any already created attributes that control bandwidth rates in the Tx and Rx directions which take a string as a value? I found USR-Initial-Tx-Link-Data-Rate and USR-Initial-Rx-Link-Data-Rate, but they take enumerated values that will not allow me to set up generic service rate (like 256Kbps or 1Mbps). I found a couple of other attributes that specific just "Data-Rate", but I can't find any that do Rx and Tx data rates. So, barring the existence of already created attributes, I'd like to set up my own vendor specific attributes -- which leads me to my main question: How do I choose a number for the Vendor-Id? For instance, Bristol's vendor ID is: VENDOR Bristol 4363 Do we have to request these from somewhere? Or, can we just pick a free one? Our AS number from ARIN is free (11541); can I just use that? Also, I have a secondary question related to this. I am setting up some bandwidth limiting scripts on our router that will limit customers' bandwidth usage. The idea is to execute a script when they authenticate which receives the AVPs from the Access-Accept packet (which would include the above mentioned Rx and Tx data rates). The script would take those attributes and instate some tc and iptables rules to shape the customers' bandwidth. When the user logs off, or the AP notices the client is gone, the AP sends an Accounting-Stop record FreeRADIUS. FreeRADIUS would then execute a cleanup script which brings down the rules that the first script instated. So, my second question is: When FreeRADIUS calls that second script, can/does it send the original Access-Accept attributes to the cleanup script? Thanks for any and all help.
