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.
