The following table describes the labels in this screen.
Table 51
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
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.
