For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN
Membership and VLAN Port" pages. These pages show which modules have
(temporarily) overridden the current Port VLAN configuration.
RADIUS attributes used in identifying a VLAN ID:
RFC2868 and RFC3580 form the basis for the attributes used in identifying a VLAN
ID in an Access-Accept packet. The following criteria are used:
• The Tunnel-Medium-Type, Tunnel-Type, and Tunnel-Private-Group-ID attributes
must all be present at least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that have the same Tag value
and fulfil the following requirements (if Tag == 0 is used, the
Tunnel-Private-Group-ID does not need to include a Tag):
- Value of Tunnel-Medium-Type must be set to "IEEE-802" (ordinal 6).
- Value of Tunnel-Type must be set to "VLAN" (ordinal 13).
- Value of Tunnel-Private-Group-ID must be a string of ASCII chars in the range '0'
- '9', which is interpreted as a decimal string representing the VLAN ID. Leading '0's
are discarded. The final value must be in the range [1; 4095].
Guest VLAN Enabled :
When Guest VLAN is both globally enabled and enabled (checked) for a given port,
the switch considers moving the port into the Guest VLAN according to the rules
outlined below.
This option is only available for EAPOL-based modes, i.e.:
• Port-based 802.1X
• Single 802.1X
• Multi 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN
Membership and VLAN Port" pages. These pages show which modules have
(temporarily) overridden the current Port VLAN configuration.
Guest VLAN Operation:
When a Guest VLAN enabled port's link comes up, the switch starts transmitting
