Доброго времени суток.Есть Freeradius 2.1.6 on Debian Lenny, Cisco Catalyst 2950, Win XP Home как supplicant. Надо на этом добре поднять 802.1x таким образом, чтобы при аутентификации пользователь в соответствии со своим логином и паролем попадал в нужный ему VLAN.
Аутентификация пользователей на Win XP Home (как ни странно но у хомяка есть 802.1x supplicant; к сожалению другой винды с поддержкой данного стандарта нет) проходит нормально и порт переходит в состояние "UP". Только вот остается в 1-м VLAN.

Из манов кашководов:
To configure VLAN assignment you need to perform these tasks:
• Enable authentication, authorization, and accounting (AAA) authorization.
• Enable IEEE 802.1x authentication (the VLAN assignment feature is automatically enabled when
you configure IEEE 802.1x authentication on an access port).
• Assign vendor-specific tunnel attributes in the RADIUS server. The RADIUS server must return
these attributes to the switch:
– [64] Tunnel-Type = VLAN
– [65] Tunnel-Medium-Type = IEEE 802
– [81] Tunnel-Private-Group-ID = VLAN name or VLAN ID
Attribute [64] must contain the value VLAN (type 13). Attribute [65] must contain the value
IEEE 802 (type 6). Attribute [81] specifies the VLAN name or VLAN ID assigned to the
IEEE 802.1x-authenticated user.
This example shows how to specify an authorized VLAN in the RADIUS server database:
cisco-avpair= ”tunnel-type(#64)=VLAN(13)”
cisco-avpair= ”tunnel-medium-type(#65)=802 media(6)”
cisco-avpair= ”tunnel-private-group-ID(#81)=vlanid”

Конфиг пользователей freeradius:
/usr/etc/raddb/users
...
user1 Cleartext-Password := "test8021x"
cisco-avpair = "tunnel-type=VLAN",
cisco-avpair = "tunnel-medium-type=802 media",
cisco-avpair = "tunnel-private-group-id=100"
...
Поскольку RADIUS работает нормально, прочих конфигов не привожу.
Спасибо
