536CHAPTER 23: MANAGING 802.1X ON THE WX SWITCH

„Supplicant timeout (configured by the set dot1x timeout supplicant command)

„RADIUS session-timeout attribute

If both of these timeouts are set, MSS uses the shorter of the two. If the RADIUS session-timeout attribute is not set, MSS uses the timeout specified by the set dot1x timeout supplicant command, by default 30 seconds.

Managing 802.1X Reauthentication of 802.1X wireless supplicants (clients) is enabled on

Clientthe WX switch by default. By default, the WX switch waits 3600 seconds

Reauthentication (1 hour) between authentication attempts. You can disable reauthentication or change the defaults.

You also can use the RADIUS session-timeout attribute to set the reauthentication timeout for a specific client. In this case, MSS uses the timeout that has the lower value. If the session-timeout is set to fewer seconds than the global reauthentication timeout, MSS uses the session-timeout for the client. However, if the global reauthentication timeout is shorter than the session-timeout, MSS uses the global timeout instead.

Enabling and

Disabling 802.1X

Reauthentication

The following command enables or disables the reauthentication of supplicants (clients) by the WX switch:

set dot1x reauth {enable disable}

Reauthentication is enabled by default.

Type the following command to reenable reauthentication of clients:

WX1200# set dot1x reauth enable success: dot1x reauthentication enabled.

Setting the Maximum

Number of 802.1X

Reauthentication

Attempts

The following command sets the number of reauthentication attempts that the WX switch makes before the supplicant (client) becomes unauthorized:

set dot1x reauth-max number-of-attempts
