IAS - What is "Tunnel-Tag"?

I am reading through MS's white paper "Deploying Windows Server 2003
Internet Authentication Service (IAS) with Virtual Local Area Networks
(VLANs)" and came across this term (see below):

Click Edit Profile, and then click the Advanced tab. By default, the
Service-Type attribute appears in Attributes with a value of Framed. By
default, for policies with access methods of VPN and dial-up, the
Framed-Protocol attribute appears in Attributes with a value of PPP. To
specify additional connection attributes required for VLANs, click Add, and
then add the following attributes:

. Tunnel-Medium-Type. Select a value appropriate to the previous
selections you have made. For example, if the remote access policy you are
configuring is a wireless policy, select: Value: 802 (Includes all 802 media
plus Ethernet canonical format).

. Tunnel-Pvt-Group-ID. Enter the integer that represents the VLAN
number to which group members will be assigned. For example, if your Sales
VLAN is on VLAN 4, type the number 4.

. Tunnel-Type. Select the value Virtual LANs (VLAN).

. Tunnel-Tag. Obtain this value from your hardware documentation.

What hardware is this refering to? NIC? I did a search on Technet for
"tunnel-tag" and came up with no definition.
