802.1X Port Authentication
21-27
21
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 (page 4-105).
• 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.
Example
dot1x re-authenticate
This command forces re-authentication on all ports or a specific interface.
Syntax
dot1x re-authenticate [interface]
interface
• ethernet unit/port
- unit - Stack unit. (Range: 1)
- port - Port number. (Range: 1-28)
Command Mode
Privileged Exec
Command Usage
The re-authentication process verifies the connected client’s user ID and
password on the RADIUS server. During re-authentication, the client remains
connected the network and the process is handled transparently by the dot1x
client software. Only if re-authentication fails is the port blocked.
Example
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
