Configuring Port-Based and Client-Based Access Control (802.1X)
802.1X Open VLAN Mode
802.1X Per-Port Configuration Port Response
Open VLAN Mode with Only an Authorized-Client VLAN Configured:
• 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. After the client disconnects, the port returns to
tagged membership in that VLAN.
Note: An authorized-client VLAN configuration can be overridden
by a RADIUS authentication that assigns a VLAN. (Refer to figure
10-1 on page 10-10.)
