dot1x multiple-authentication

dot1x multiple-authentication
Sets the IEEE 802.1X authentication submode to terminal authentication mode. The
command performs authentication for each terminal and the authentication result
determines whether communication is possible. Accordingly, multiple terminals can be
connected.
If terminal authentication mode is not set as the authentication submode, single mode is
used as the submode. Single mode authentication permits connection of only one terminal.
When multiple terminals are connected, the status of the interface that has been set
changes to no authentication.
Syntax
To set information:
dot1x multiple-authentication
To delete information:
no dot1x multiple-authentication
Input mode
(config-if)
Parameters
None
Default behavior
The authentication submode is single mode.
Impact on communication
If the authentication submode is changed, the authentication status of the interface that has
been set is initialized. As a result, authenticated terminals must be re-authenticated. Until
the terminals are re-authenticated, communication is impossible.
When the change is applied
The change is applied immediately after setting values are changed.
Notes
1. All IEEE 802.1X settings take effect when the dot1x system-auth-control
command is set.
2. See Table 22-1 Configuration commands and IEEE 802.1X authentication modes for
the authentication mode in which the command's settings are operable.
3. This command takes effect only when
auto is set for the dot1x port-control
command.
4. If the authentication submode is changed, the authentication status of the interface
that has been set is initialized. As a result, authenticated terminals must be
re-authenticated.
5. Behavior of a terminal configured by using the
mac-address-table static
command is as follows:
 When this
command has not been set (single mode)
Communication is impossible as long as a terminal subject to authentication
has not been authenticated successfully.
