User Guidelines
The N1100-ON and N1500 Series switches support up to 32 users per
interface.
Example
The following command limits the number of devices that can authenticate
on port gigabitethernet 1/0/2 to 3.
console(config-if-Gi1/0/2)#dot1x max-users 3
dot1x port-control
Use the dot1x port-control command in Interface Configuration mode to
configure the 802.1x mode of authentication on the port. Use the no form of
the command to return the mode to the default.
Syntax
dot1x port-control {force-authorized | force-unauthorized | auto | mac-
based}
no dot1x port-control
• 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.
