authentication mode is set to “auto” or “macbased” (using the dot1x
state command described on page 269).
EXAMPLE

dot1x
reauthentication
This command displays or sets periodic re-authentication for all ports.
SYNTAX
dot1x reauthentication [enable | disable]
enable - Schedules reauthentication to whenever the quiet-period
of the port runs out (port-based authentication). For MAC-based
authentication, reauthentication will be attempted immediately. The
process only effects successfully authenticated ports/clients and will
not cause the port/client to be temporarily unauthorized.
disable - Disables 802.1X reauthentication.
DEFAULT SETTING
Disabled
COMMAND USAGE
◆ For port-based authentication, the re-authentication process verifies
the connected client’s user ID and password on the RADIUS server.
During re-authentication, the client remains connected to the network
and the process is handled transparently by the dot1x client software.
Only if re-authentication fails is the port blocked.
◆ The connected client is re-authenticated after the interval specified by
the dot1x period command (see page 272). The default is 3600
seconds.
◆ This command is only effective when 802.1X is globally enabled (using
the dot1x mode command described on page 269) and the port's
authentication mode is set to “auto” or “macbased” (using the dot1x
state command described on page 269).
