You may not have to completely dump your cisco 2511, the new cisco IOS
will support radius but will probably require more system flash. We are in the
process of moving all 100+ of of our cisco term-servers to radius from tacacs.
We got the flash upgrades from Ingram-Micro which was a heck of a lot cheaper
than from a cisco dealer.
