85.3 Activate MAC Authentication
Use this screen to activate MAC authentication. Click SECURITY > Port Authentication > MAC
Authentication to display the configuration screen as shown.
Active Select this to permit 802.1x authentication on this port. You must first allow 802.1x
authentication on the Switch before configuring it on each port.
Max-Req Specify the number of times the Switch tries to authenticate clients before sending
unresponsive ports to the Guest VLAN.
This is set to 2 by default. That is, the Switch attempts to authenticate a client twice. If the client
does not respond to the first authentication request, the Switch tries again. If the client still does
not respond to the second request, the Switch sends the client to the Guest VLAN. The client
needs to send a new request to be authenticated by the Switch again.
Reauth Specify if a subscriber has to periodically re-enter his or her user name and password to stay
connected to the port.
Reauth-period
secs Specify the length of time required to pass before a client has to re-enter his or her user name
and password to stay connected to the port.
Quiet-period secs Specify the number of seconds the port remains in the HELD state and rejects further
authentication requests from the connected client after a failed authentication exchange.
Tx-period secs Specify the number of seconds the Switch waits for client’s response before re-sending an
identity request to the client.
Supp-Timeout
secs Specify the number of seconds the Switch waits for client’s response to a challenge request
before sending another request.
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.
