I hate the Cisco MICA modems. Very bad. The auto re-download of
modem firmware after a certain number of connect failures, during which it
may busy out several modems for hours, has got to be the stupidest thing
I've ever seen. Make sure you install at least 8 extra modems in Cisco to
make sure you don't have problems with this. Oh wait, most Cisco RASes
don't have slots for extra modems!
I have also have seen every single modem in the box suddenly fail to
complete modem handshaking with everything. A reload fixed it.
If you want to talk about non-modem Cisco issues, lets talk about RADIUS
attributes. IOS's handling of RADIUS attributes will change unpredictable
between IOS versions. I currently have a 5200 running a version of IOS
that will refuse logins for any user with "Idle-Timeout = 0", but if the
value is > 0, that user can login. But that only holds true for modem
calls! For ISDN calls, logins are refused for all values of
"Idle-Timeout"! This is truly bizare. So much for per-user idle-timeout
settings.
