Chapter 16 Port Authentication

The following table describes the labels in this screen.

Table 41 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.
