[nsp] Dynamically changing virtual-access interface configuration

[leon.c at staff.ihug.co.nz]

We have a couple of 7301s terminating PPPoE sessions. We are using RADIUS
to apply per-user rate limit sessions on each virtual-interface.

Eg:
interface Virtual-Access9
 ip unnumbered Loopback0
 rate-limit input 256000 16000 16000 conform-action transmit exceed-action
drop
 rate-limit output 256000 16000 16000 conform-action transmit
exceed-action drop
 no logging event link-status

The question is, is there a way at all to change the rate-limit for
individual virtual-access interfaces without having to disconnect the
users to apply another RADIUS profile.

We are currently using Version 12.3(5). The older 12.2 version we were
testing on a 7200 used to allow manual changing of virtual-access
interface configurations just like any other interfaces. However, this
seems to have been disabled in 12.3.

#int virtual-access 16
% Please use virtual template to configure your virtual access

This is what I see every time this is attempted. Is there a way around
this? Since which version was this feature disabled?

Regards,
