Show Client Status

Show Client Status

The table below shows the possible client status information that may be reported by a Web-based or MAC-based ‘show... clients’ command.

Reported Status	Available Network		Possible Explanations
	Connection

authenticated	Authorized VLAN		Client authenticated. Remains
			connected until logoff-period or
			reauth-period expires.
authenticating	Switch only		Pending RADIUS request.
rejected-no vlan	No network access	1.	Invalid credentials supplied.
		2. RADIUS Server difficulties. See log
			file.
		3. If unauth-vid is specified it cannot be
			successfully applied to the port. An
			authorized client on the port has
			precedence.
rejected-unauth vlan	Unauthorized VLAN only	1.	Invalid credentials supplied.
		2. RADIUS Server difficulties. See log
			file.
timed out-no vlan	No network access		RADIUS request timed out. If unauth-
			vid is specified it cannot be
			successfully applied to the port. An
			authorized client on the port has
			precedence. Credentials resubmitted
			after quiet-period expires.
timed out-unauth vlan	Unauthorized VLAN only		RADIUS request timed out. After the
			quiet-period expires credentials are
			resubmitted when client generates
			traffic.
unauthenticated	Switch only		Waiting for user credentials.
