Can somebody tell me the difference between RSM or SupIII netflow for a Cat5000 switch? I know both can do multi-layer switching. Which is better for inter-vlan routing? Its seem to me the RSM is hardware and the SUPIII is software. Does anybody have comparasions? Thank you

RSM or SupIII

The RSM is a router on a blade.. it uses the backplane as the interface.. When used with CatOS 4.1 or newer, it can play the role of the Route Processor and the Cat5K is the Switch Engine. With the SupIIG or SupIIIG, you could use an external 4000 series router and up to be an external Route Processor instead of using an RSM.
The NFFC is a *daughter* card for some of the IIs and IIIs. The IIG and the IIIG has the NFFC Daughter card already built in. With the G's you have the optional Route Switch Feature Card (RSFC) that can be installed which takes the place of the RSM blade.
Switching requires silicon.. so multilayer switching requires both the special hardware AND the correct version of software.
I'm sure I've missed a few details so if anyone has pearls of wisdom, please add to the thread.
