I'm doing a migration from ACS 3.x to 5.3, which basically means to rebuild everything from scratch.
The authenication client is in this case an 2G/3G gprs/umts operator.
The real client is a cisco router with a 3G wic, dialing into the operators network with ppp/chap and dynamic (on the router dialer) ip address.
Talking aganst the old 3.x acs this works fine, but when switching over to the new acs 5.3 the router authenticates but can not build an ip link for some - so far unknown - reason.
I sniffed the radius communication and i notice that the reply from the acs3 is different from the acs 5.3 system.
acs 3 replies with av-pairs:
- framed-ip-address(8)
- class(25)
acs 5.3 replies with av-pairs:
- user-name(1)
- framed-ip-address(8)
- class(25)
Could this be the reason tham my remote router will not build ip connectivity over 3G with acs 5.3?
And if so - how do i remove the user-name av-pair?
Thanks,
