I know that it has been asked before, but either I've never seen the
answer, or forgotten what it was - in that case, sorry.

What exactly is the switch processor DRAM used for?  Why could it want
to have 1 Gb memory?

I assume route processor DRAM is used for IOS, BGP tables (RIB), CEF
tables (FIB), and all the other things IOS wants memory for.

TCAM space is needed for FIB and ACLs.

switch processor DRAM?  IOS, CAM tables (mac addresses), ...?
