The following table describes the labels in this screen.
Table 45 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.
* Use this row to make the setting the same for all ports. Use this row first
and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
Active Select this checkbox to permit MAC authentication on this port. You must
first allow MAC authentication on the Switch before configuring it on
each port.
Apply Click Apply to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
