I configured the HTTP auth-proxy on a cisco router 2611XM (IOS 12.2 11T). The configuration is attached. Among them, 192.168.75.100 is the ACS server, 192.168.75.151 is the client machine, 192.168.75.11 is the router.
The issue is when I tried to http to 192.168.75.11 from the client, there's no aaa traffic between the router and ACS server (however, AAA works when I log in to the router).
It will highly appreciated if anyone can give me some hints.
