Active
Select this check box to permit MAC authentication on the Switch.
Note: You must first enable MAC authentication on the Switch before configuring it
on each port.
Name Prefix
Type the prefix that is appended to all MAC addresses sent to the RADIUS server for
authentication. You can enter up to 32 printable ASCII characters.
If you leave this field blank, then only the MAC address of the client is forwarded to the RADIUS
server.
Password
Type the password the Switch sends along with the MAC address of a client for authentication
with the RADIUS server. You can enter up to 32 printable ASCII characters.
Timeout
Specify the amount of time before the Switch allows a client MAC address that fails
authentication to try and authenticate again. Maximum time is 3000 seconds.
When a client fails MAC authentication, its MAC address is learned by the MAC address table
with a status of denied. The timeout period you specify here is the time the MAC address entry
stays in the MAC address table until it is cleared. If you specify 0 for the timeout value, the
Switch uses the
Ag ing Tim e
configured in the
Switc h Se tup
screen.
Note: If the
Ag ing Tim e
in the
Switc h Se tup
screen is set to a lower value, then it
supersedes this setting. See
Section 8.5 on page 82
.
Port
This field displays a port number.
