Вот это я нашел в документе Cisco IOS Wireless LAN Commands
match vlan
To define the VLAN match criteria, use the match vlan command in class-map configuration mode. To remove the match criteria, use the no form of this command.
match vlan {vlan-id | vlan-range | vlan-combination}
no match vlan

The VLAN identification number. Valid range is from 1 to 4094; do not enter leading zeros.
vlan-range
A VLAN range. For example, 1 - 3.
vlan-combination

Command History
Release Modification

Usage Guidelines
Use the match vlan command to specify which fields in the incoming packets are examined to classify the packets. Only the IP access group or the MAC access group matching the Ether Type/Len field are supported.
Examples
The following example shows how to classify traffic by VLAN:
Router(config-cmap)# match vlan 2
Короче нужен IOS с поддержкой данной функции, но для Cisco 2821.
Причем я даже не знаю имеется ли таковой для данной железяки...
Всем заранее спасибо за ссылки или комметарии.
