VLAN tag is the RADIUS-assigned VLAN or the unauthenticated VLANs.
See the
command to enable RADIUS VLAN
assignment at a port.
The switch removes from the FDB all MAC addresses learned on a port when
its authentication status is changed from authorized to unauthorized.
Multi-Host Mode
The multi-host mode manages the authentication status of the port: the port
is authorized after at least one host is authorized.
When a port is unauthorized and the guest VLAN is enabled, untagged traffic
is remapped to the guest VLAN. Tagged traffic is dropped unless the VLAN
tag is the guest VLAN or the unauthenticated VLANs. If guest VLAN is not
enabled on the port, only tagged traffic belonging to the unauthenticated
VLANs is bridged.
When a port is authorized, untagged and tagged traffic from all hosts
connected to the port is bridged, based on the static VLAN membership
configured at the port.
A user can specify that untagged traffic from the authorized port will be
remapped to a VLAN that is assigned by a RADIUS server during the
authentication process. In this case, tagged traffic is dropped unless the
VLAN tag is the RADIUS-assigned VLAN or unauthenticated VLANs. See
the
command to enable RADIUS VLAN
assignment at a port.
The switch removes from FDB all MAC addresses learned on a port when its
authentication status is changed from authorized to unauthorized.
Multi-Sessions Mode
Unlike the single-host and multi-host modes (port-based modes) the multi-
sessions mode manages the authentication status for each host connected to
the port (session-based mode). If the multi-sessions mode is configured on a
port, the port does have any authentication status. Any number of hosts can
be authorized on the port. The
command can limit the
maximum number of authorized hosts allowed on the port.
Each authorized client requires a TCAM rule. If there is no available space in
the TCAM, the authentication is rejected.
When using this command to change the port mode to single-host or multi-
host when authentication is enabled, the port state is set to unauthorized.
