Hi, Just agreeing with Arran really, we've got 5406 procurve switches, which I believe are similar in software terms to the 2910s and we do the unlang string Arran has presented here : update reply { Egress-VLANID += "%{expr:822083584 + %{Tagged-VID}}" } It works fine, although that may not help you too much. I had some 2910s around here somewhere, maybe I'll test one..

I'm honestly not entirely sure why the freeradius dictionary has the attribute as an unsigned int

That's what the RFCs say. And the server doesn't really have a way of packing arbitrary structures from attributes.

It says the value is 4 octets. That's not quite saying it's an integer, was there a later one? I think it's arguably more useful as an integer though, for the reasons listed previously, and because you can use expr to build the bit string easily. For example: update reply { Egress-VLANID += "%{expr:822083584 + %{Tagged-VID}}" } With hex you need to manually pad the VID out to 12 bits.
