CoA on a 7206


I'm trying to get CoA working on a 7206, and although it seems a fairly staright forward setup, I just can't make it work.  Here are the following details that I have.

I'm using CoA Client (version 2.6) to do the testing.   From the 7206 I get the following output from the debug.

Aug  2 15:16:46:  ++++++ CoA Attribute List ++++++

Aug  2 15:16:46: 57259958 0 00000001 addr(7) 4 x.x.x.x (client session)

Aug  2 15:16:46:

Aug  2 15:16:46: COA: No matching entry found

Aug  2 15:16:46: COA: Added Reply Message: No Matching Session

Aug  2 15:16:46: COA: Added NACK Error Cause: Session Context Not Found

Aug  2 15:16:46: COA: Sending NAK from port 1700 to x.x.x.x/1700   (from server sending CoA request)

Aug  2 15:16:46: RADIUS:  18  21  4E6F204D61746368696E672053657373696F6E

Aug  2 15:16:46: RADIUS:  101 6   000001F7

and here's what I'm sending from the server sending the CoA requests: - when I use the same tool and try and disconnect the same session it works... 

coa_w32.exe -n <coa server IP> -p 1700 -s 1700 -k secret123 -1 8,IP<client's IP>

IOS:  12.4(24)T7 advanced services

CoA config: 

aaa server radius dynamic-author

  client x.x.x.x server-key xxxxxxxx

server-key xxxxxxx

auth-type any

AAA config:

aaa new-model



aaa authentication username-prompt "Username: login: "

aaa authentication login go-radius group radius local

aaa authentication login console-logins line

aaa authentication ppp default none

aaa authentication ppp go-radius if-needed group radius

aaa authorization network default group radius none

aaa authorization network go-radius group radius

aaa authorization network permit none

aaa accounting delay-start

aaa accounting nested

aaa accounting update periodic 10

aaa accounting network default

action-type start-stop

group radius

aaa session-id common

RADIUS config:

radius-server attribute nas-port format e UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

radius-server dead-criteria tries 20

radius-server host x.x.x.x auth-port 1812 acct-port 1813

radius-server source-ports extended

radius-server timeout 30

radius-server deadtime 10

radius-server key x.x.x.x

radius-server vsa send cisco-nas-port

radius-server vsa send accounting

radius-server vsa send authentication

Any help would be appreciated.

CoA on a 7206

I suspect my problem is that the IOS version I have doesn't support the feature - it will do PoD, but not CoA.  I'm going to need to move to an ISG IOS.
