Chapter 17 Configuring RADIUS
Configuring RADIUS Servers
To configure periodic RADIUS server monitoring, perform this task:
The following example shows how to configure periodic RADIUS server monitoring:
switch# configure terminal
switch(config)# radius-server host 10.10.1.1 test username user1 password Ur2Gd2BH
idle-time 3
switch(config)# radius-server deadtime 5
switch(config)# exit
switch# show radius-server
switch# copy running-config startup-config
Configuring the Dead-Time Interval
You can configure the dead-time interval for all RADIUS servers. The dead-time interval specifies the
time that the Nexus 5000 Series switch waits after declaring a RADIUS server is dead, before sending
out a test packet to determine if the server is now alive. The default value is 0 minutes.
Note When the dead-time interval is 0 minutes, RADIUS servers are not marked as dead even if they are not
responding. You can configure the dead-time interval for a RADIUS server group (see the “Configuring
RADIUS Server Groups” section on page 17-7).
To configure dead time interval, perform this task:
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# radius-server host
{ipv4-address | ipv6-address | host-name}
test {idle-time minutes | password
password [idle-time minutes] | username
name [password password [idle-time
minutes]]}
Specifies parameters for server monitoring. The
default username is test and the default password is
test. The default value for the idle timer is 0 minutes.
The valid range is 0 to 1440 minutes.
Note For periodic RADIUS server monitoring,
you must set the idle timer to a value greater
than 0.
Step 3
switch(config)# radius-server deadtime
minutes
Specifies the number of minutes before the Nexus
5000 Series switch checks a RADIUS server that
was previously unresponsive. The default value is 0
minutes. The valid range is 1 to 1440 minutes.
Step 4
switch(config)# exit
Exits configuration mode.
Step 5
switch# show radius-server
(Optional) Displays the RADIUS server
configuration.
Step 6
switch# copy running-config startup-config
(Optional) Copies the running configuration to the
startup configuration.
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
#switch(config)# radius-server deadtime
Configures the dead-time interval. The default value is
0 minutes. The range is from 1 to 1440 minutes.
