■
Specifies the interval of multicasting 802.1x request packets periodically. In
order to be compatible with clients who do not send EAPoL-Start frames
actively, Switch 8800 Family switches will multicast 802.1x request packets
periodically. The clients will respond after receiving these packets. tx-period
specifies the period of multicasting 802.1x request packets.
tx - period - value : Specifies how long the duration of the transmission timeout timer
is. The value ranges from 10 to 120 in units of second and defaults to 30.

It is recommended to configure different handshake period value and handshake
timeout times according to the number of users:
■
When the number of users is 2048, the handshake period value should be no
smaller than 2 minutes, and the handshake timeout times should be no less
than 3 times;
■
When the number of users is 1024, the handshake period value should be no
smaller than 1 minutes, and the handshake timeout times should be no less
than 3 times
■
When the number of users is 512, the handshake period value should be no
smaller than 30 seconds, and the handshake timeout times should be no less
than 2 times.
Enabling/Disabling
Quiet-Period Timer You can use the following commands to enable/disable a Quiet-Period timer of an
Authenticator (such as a 3Com Series Switch). If an 802.1x user has not passed the
authentication, the Authenticator will keep quiet for a while (which is specified by
dot1x timer quiet-period command) before launching the authentication again.
During the Quiet Period, the Authenticator does not do anything related to 802.1x
authentication.
Perform the following configuration in system view.
By default, Quiet-Period timer is disabled.
