Table F.8. Change-of-Authorisation

AVP	No.	Usage
Acct-Session-Id	44	Unique ID for session
Chargeable-User-Identity	89	This is used as CQM graph name.
Framed-Route	22	May appear more than once. Text format is IPv4-Address/Bits 0.0.0.0 metric. The target IP is ignored but must be valid IPv4 syntax. The metric is used as localpref in routing.
Delegated-IPv6-Prefix	123	IPv6 prefix to be routed to line. Maximum localpref used.
Framed-IPv6-Prefix	97	IPv6 prefix to be routed to line. Maximum locapref used.
Framed-IPv6-Route	99	May appear more than once. Text format is IPv6-Address/Bits :: metric. The target IP is ignored but must be valid IPv6 syntax. The metric is used as localpref in routing. Alternative format IPv6/Bits IPv4-Address metric defines that prefix is to be protocol 41 IPv4 tunneled to specified target via this link.
Session-Timeout	27	Absolute limit on session, in seconds
Terminate-Action	29	If not specified, or 0, then terminate on Session-Timeout or Quota reached, else send RADIUS Interim accounting update (not an Access Request)
Connect-Info	77	Text tx speed limit to apply to session
Filter-Id	11	See filter ID section

The session is identified by Acct-Session-Id if present, else by Chargeable-User-Identity. No other identification parameters are supported. If sent then they are ignored.

Parameters are left unchanged if not specified.

If any route entries (IPv4 or IPv6) are present then the existing routing (apart from the PPP endpoint address) are all removed and replaced with what has been sent. To clear all routes send a framed route with a blank string. The Framed-IP-Addreess cannot be changed.
To clear the session timeout send a value of 0.
To clear outbound shaping send connect speed of "0".

No other parameters are supported, and if sent then they are ignored
