Also, IP1 cards only shipped with 4MB of SSRAM vs the 8MB or higher in all 
the IP II cards I know of, so you get less capacity to hold routes in the 
PFE.

I've seen people keep SSB non-E's around in their M20s as a "cheap backup" 
so that incase the primary SSB fails the router keeps working, you just 
lose your filtering etc capabilities.

Some very anemic pages in need of more content:

There is a reference to CoS functionalities in there, but I'm not sure 
what that is about specifically.
