unlang substring with nas-port-id

[Kris]

Hi,

Not sure about it but I think you might be able to use regex to do that.
It may be something like:

if("%{NAS-Port-Id}" =~ / \b[1-4][0-9]{3}/) { #this to extract the vlan

         switch "%{1}" { #this to refer to the matched vlan tag substring

                 case 1000 {
                         ....
                 }

                 case 1001 {
                         ....
                 }
                 ....
         }
}

But you might need to double check the syntax in man unlang. Hopefully 
someone will correct me on this.

Regards,
Krzysztof
