server.
1. Default value when this parameter is omitted:
The number of times set by using the
radius-server retransmit command
is used. If no value is set, the initial value is 3.
2. Range of values:
0 to 15 (times)
key <String>
Specifies the RADIUS key used for encryption or for authentication of
communication with the RADIUS server. The same RADIUS key must be set for the
client and the RADIUS server.
1. Default value when this parameter is omitted:
The RADIUS key set by using the
radius-server key command is used. If
no key is set, the RADIUS server is disabled.
2. Range of values:
Specify a character string that has no more than 64 characters. For details
about the characters that can be specified, see Any character string in
Specifiable values for parameters.
Default behavior
The RADIUS server settings registered by using the radius-server host command are
used.
If the
radius-server host command is not registered, authentication cannot be
performed.
Impact on communication
None
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. When this command is set, the setting information of the RADIUS server referenced
by IEEE 801.X authentication has precedence over the information set by the
radius-server host command (the settings of the radius-server host command
are not applied). For details about the settings of general-use RADIUS server
information and the IEEE 802.1X authentication RADIUS server information, see
Configuration Guide Vol. 2.
4. A maximum of 4 IEEE 802.1X authentication RADIUS servers can be specified for
each Switch.
5.
127.*.*.* cannot be set as an IPv4 address.
6. If the
key parameter is omitted and the radius-server key command is not set, the
RADIUS server is disabled.
7. If multiple IEEE 802.1X authentication RADIUS servers are configured, the address
displayed first by using the
show radius-server operation command is the address
of the primary RADIUS server. The primary IEEE 802.1X authentication RADIUS
