[c-nsp] Which switch can do what we need?

[Tom Storey]

Hey Skeeve,

Re config size, have you thought about using "service compress-config"?

This might help to reduce the config size by about 25-30%, which may
or may not be enough, or may not be enough for long enough.

Just a quick dir I did before adding command:

Router#dir nvram:
Directory of nvram:/

  237  -rw-        1292                    <no date>  startup-config

And after:

Router#wr
Building configuration...

Compressed configuration from 1316 bytes to 829 bytes[OK]
Router#dir nvram:
Directory of nvram:/

  237  -rw-         829                    <no date>  startup-config

Though if your config is that big, maybe it is just worth finding a
box with bigger NVRAM anyway. :-)

Also I wonder, on some Cat switches NVRAM is just flash emulated
anyway (which might explain why some of them write their config so
quickly...) I wonder if theres some special command that can increase
the amount allocated to the virtual NVRAM?
