802.1X Open VLAN Mode
Open VLAN Mode with Only an Authorized-Client VLAN Configured:
802.1X Per-Port Configuration Port Response
• Port automatically blocks a client that cannot initiate an
authentication session.
• If the client successfully completes an authentication session, the
port becomes an untagged member of this VLAN.
• If the port is statically configured as a tagged member of any other
VLAN, 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. 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.
Note: An authorized-client VLAN configuration can be overridden
by a RADIUS authentication that assigns a VLAN. (Refer to figure
12-1 on page 12-11.)
