Table 40 Advanced Application > Port Authentication > MAC Authentication
LABEL DESCRIPTION
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, then this entry will not be deleted from the MAC
address table.
Note: If the Aging Time in the Switch Setup screen is set to a
lower value, then it supersedes this setting. See Section 7.5
on page 81.
Port This field displays a port number.
