[RADIATOR] CoA / Change-of-Authorization / Change-Filter-Request

[Michael]

I give up.  I've searched for hours for a hint at what this CoA / 
Change-of-Authorization / Change-Filter-Request is.  I think it is what 
i'm looking for.

I have the usual problem of too much info on the internet, and not 
enough of it makes sense to me.  For radiator specific, i can only find 
1 mention for Change-Filter-Request in the manual and it only says 
radpwtst can send this code.  The website says in the changelog there's 
a fix for a bug.

i've run across a couple examples for radpwtst:
-code Change-Filter-Request User-Name=whatever Message-Authenticator=xxxxx

and

-code Change-Filter-Request Account-Info="Sx.x.x.x" Command-Code="04 20"


I'm just looking to know if you can change the rate limit of a current 
session on a cisco device.

I was kinda hoping something like this would work:
-code Change-Filter-Request User-Name="test" cisco-Policy-Down="rate1M"
or:
code Change-Filter-Request Acct-Session-Id="00000012" 
cisco-Policy-Down="rate1M"

if also tried with the cisco-avpair attr.


all I ever get in the cisco debug is:

...
++++++ CoA Attribute List ++++++
84F09FA4 0 00000009 string-session-id(339) 8 00000005
...
COA: No matching entry found
COA: Added Reply Message: No Matching Session
...


why nothing matches, i don't know. the session-id is correct. but since 
i don't know anything about the COA, i'm not even sure if i'm barking up 
the right tree.

My Disconnect-Request process works fine which uses a similar process.
