•When the port detects a client, it automatically becomes an untagged member of this VLAN. To limit security risks, the network services and access available on this VLAN should include only what a client needs to enable an authentication session. If the port is statically configured as an untagged member of another VLAN, the switch temporarily removes the port from membership in this other VLAN while membership in the
•After the client is authenticated, and if the port is statically configured as an untagged member of another VLAN, the port’s access to this other VLAN is restored.
Note: If RADIUS authentication assigns a VLAN to the port, this assignment overrides any statically configured, untagged VLAN membership on the port (while the client is connected).
•If the port is statically configured as a tagged member of a VLAN that is not used by 802.1X Open VLAN mode, the port returns to tagged membership in this VLAN upon successful client authentication. This happens even if the RADIUS server assigns the port to another, authorized VLAN. Note that if the port is already configured as a tagged member of a VLAN that RADIUS assigns as an authorized VLAN, then the port becomes an untagged member of that VLAN for the duration of the client connection. After the client disconnects, the port returns to tagged membership in that VLAN.
