[c-nsp] Really need help with atm vc-per-vp on NM-4T1 3640

[Brian Turnbow]

Hi Ruben
>From sh atm int 
  0VCIs per VPI: 1024,
>From sh int 
 1024 VCs per VP,

So 1024 vc per VP is configured. 
I think where you are getting confused is the max active vcs
The nms support max 256 per interface 1024 per card.

Ruben,

what does "show atm int atm x/y" tell you? It should print the current
setting of the VC-PER-VC value..
