802.1X Port Authentication
Command Usage
• The “max-count” parameter specified by this command is only effective if the dot1x mode is
set to “auto” by the
dot1x port-control command.
• In “multi-host” mode, only one host connected to a port needs to pass authentication for all
other hosts to be granted network access. Similarly, a port can become unauthorized for all
hosts if one attached host fails re-authentication or sends an EAPOL logoff message.
• In “mac-based-auth” mode, each host connected to a port needs to pass authentication. The
number of hosts allowed access to a port operating in this mode is limited only by the available
space in the secure address table (i.e., up to 1024 addresses).
Example
Console(config)#interface eth 1/2
Console(config-if)#dot1x operation-mode multi-host max-count 10
Console(config-if)#
dot1x port-control
This command sets the dot1x mode on a port interface. Use the no form to restore the default.
Syntax
dot1x port-control {auto | force-authorized | force-unauthorized}
no dot1x port-control
auto – Requires a dot1x-aware connected client to be authorized by the RADIUS server.
Clients that are not dot1x-aware will be denied access.
force-authorized – Configures the port to grant access to all clients, either dot1x-aware
or otherwise.
force-unauthorized – Configures the port to deny access to all clients, either dot1x-aware
or otherwise.
Default
force-authorized

Example
Console(config)#interface eth 1/2

Console(config-if)#
dot1x re-authentication
This command enables periodic re-authentication for a specified port. Use the no form to disable
re-authentication.
Syntax
[no] dot1x re-authentication
