Security Commands 1110
• auto — Enables 802.1x authentication on the interface and causes the
port to transition to the authorized or unauthorized state based on the
802.1x authentication exchange between the switch and the client. Once
the first data client is authenticated, any other clients on the interface
have access to the data VLAN. This is equivalent to IEEE 802.1X port-
based mode. VLAN assignment is allowed on the port if it is not
configured in trunk mode. This is the default port-control authentication
method.
• force-authorized — Disables 802.1x authentication on the interface and
causes the port to transition to the authorized state without any
authentication exchange required. The port sends and receives normal
traffic without 802.1x-based authentication of the client. VLAN
assignment is not supported in this mode.
• force-unauthorized — Denies all access through this interface by forcing
the port to transition to the unauthorized state, ignoring all attempts by
the client to authenticate. The switch cannot provide authentication
services to the client through the interface. VLAN assignment is not
supported in this mode.
Default Configuration
The default port-control mode is auto (N1100, N1500, N2000, N2100,
N3000E, N3100 switch models). The default port-control mode is force-
authorized (N2200, N3200 switch models).

User Guidelines
Interface configuration takes precedence over the global port-control setting.
It is recommended that you disable spanning tree or enable spanning-tree
portfast mode on 802.1x edge ports (ports in auto state that are connected to
end stations) in order to go immediately to the forwarding state after
successful authentication. Edge ports are ports connected to end stations that
do not forward traffic to other stations and do not participate in spanning-
tree.
