The RSM is a separate blade that fills one of the catalyst slots, and 
contains what is about as powerful as a Cisco 7500 RSP2 (100 MHz R4700).

IOS for RSM is available up to 12.2 main line.


The RSFC is a daughter card for some supervisors, e.g. the Sup III G.
It's more powerful than the RSM (200 MHz R5000), but unfortunately it's
only supported up to IOS 12.1 - resulting in the perverse situation
that you can't really use the faster board for interfaces with higher
throughput (= requiring a faster router...) if you need interface-based 
accounting, as the RSFC has no 64 bit counters, while the RSM has...

The RSFC could have been a *really* nice engine, but Cisco product 
marketing has effectively made it much less useful than it could be.
