Chapter 16 Port Authentication Figure 71 Advanced Application > Port Authentication > MAC 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. Name Prefix Password Timeout Note: You must first enable MAC authentication on the Switch before configuring it on each port. 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. 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. 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.
