[j-nsp] spmb/ssb/feb/... memory usage details?

[Pekka Savola]

Hi,

You can use the 'show chassis spmb/feb/ssb/...' to view DRAM memory 
utilization on the switch board.

How can you find out what's taking DRAM memory?  'show route summary' 
on 'vty ssb' (or similar) shows how much your routing table takes but 
that's all I can find out.

This is a timely topic because if you have 64MB of memory, the full 
DFZ table and some features enabled (RPF?) result in memory running 
out.

So it'd nice to figure what's taking all the memory so you could which 
features you must not enable if you don't want to break your network 
(this feels somehow familiar...)

Similarly, figuring out the SRAM usage might be interesting.
