Cisco-NAS-Port in ios 12.3

[aaanet]

Hi folks,

I would like to know how to find out name(or number)

of virtual interface when pppoe client authenticates on server.

With ios version 12.2 our radius got right attributes

from pppoe server like:

NAS-Port = 11

Cisco-NAS-Port = "Virtual-Access11"

NAS-Port-Type = Virtual

But after upgrading ios to 12.3

pppoe server send different attributes to radius:

NAS-Port-Type = Virtual

Cisco-NAS-Port = "1/0/0/40"

NAS-Port = 0

How can i restore old behavior

or find out right virtual-access?

Thanks

I think the command show vpdn-group command specifies the interface on which the PPOE auhtenticates can be found.
