[c-nsp] Limits on virtual-access interfaces ?

[Mike]

Howdy,

	I have a 7201 terminating pppoe sessions. I ran the following command 
and saw that the max virtual-access interface number was 900, per below:

sh int virtual-access ?
   <1-900>  Virtual-Access interface number

	I am wondering if this is actually a dynamic number?
My high water pppoe sessions (max up at one time) is 898, and so I am 
wondering if I will hit this limit or if it will grow once I cross that 
threshold?

Thanks.

Mike-
