AAA Server IP Pool based on AAA Client

Andy Robinson · ‎05-21-2007

Hi,

I have a scenario where I need to be able to allocate an IP address to a user group from a pool on the AAA server based on the AAA client that the user authenticates against.

So for example if the user comes in on CPE1 they get assigned an address from Pool A, if they come in on CPE2 they get an address assigned from Pool B.

Any pointers on how to do this (if possible) would be greatly appreciated.

Thanks in advance

Andy

With ACS v4 you could do this....

Define your pools and add your devices to their own NDGs. Then define a NAP which is triggered off each NDG. Each NAP can use its own group mapping scheme which each target group using a different IP pool.

Probably only works when users are external as you need group mapping to make it work.

A bit cludgy.. but should work.
