Parameter

List of Ethernet ports, expressed as
interface-list
= {

[
to
interface-name
] } & < 1-10 >. The
interface-name
argument specifies the port index of
an Ethernet port and can be specified in this form:
interface-name
= {
interface-type
interface-num
}, where
interface-type
specifies the type of a port and
interface-num
identifies the port number. "&<1-10>" means that up to 10 port indexes/port index lists
can be provided.
Description
Use the
dot1x re-authenticate
command to enable 802.1x re-authentication on the
specified port or on all Authenticator ports of the switch.
Use the
undo dot1x re-authenticate
command to disable 802.1x re-authentication on
the specified port or on all Authenticator ports of the switch.
By default, 802.1x re-authentication is disabled on all ports.
When you use this command in system view, if you do not specify a port, this command
will enable 802.1x re-authentication on all ports; if you provide a value for the
interface-list
argument, this command will enable 802.1x on the specified port.
When you use this command is Ethernet port view, the
interface-list
argument is not
available and 8021.x re-authentication is enabled on the current port only.
802.1x must be enabled globally and on the current port before 802.1x
re-authentication can be configured on the port.
Example
# Enable 802.1x re-authentication on the port Ethernet 3/0/1.
<3Com>system-view
