For those saying Cisco is so great, it's still fucked up pretty bad. IOS
12.1 and later doesn't allow an MTU > 1460 on L2TP, while 12.0.7(T) works
fine with a 1492 MTU that my PPPoE customers expect. Every rev I've tried
from 12.0 and up has problems with CEF when using ISL VLAN sub-interfaces,
and without CEF, mac-accounting is screwed up.
Now if they charged 1/5th of what they do, I'd say you're getting
reasonable value for your dollar...

I believe this is an operational issue list and not a flame / bash Cisco
list. Instead of looking at the glass half full, look at it as half
empty and look at how far IOS has come in the past two years. Sure they
have some bugs and shortcomings, but if you think anyone else out there
is any better at this game, drop Cisco and go with them. Or maybe the
best thing to do is keep pushing your TAC case until they resolve the
problem and relate your problems to open cases on the bug tracker.
IMHO if you look at IOS as a whole and compare the good with the bad,
it's hardly "fucked up pretty bad".
If thats the worst Cisco bug you've got, you are the luckiest man on the
face of the earth. Everyone has bugs, but Cisco has better excuses to go
along with them.
