DESCRIPTION
You can use the radius component to configure a custom monitor, or you can use the default RADIUS monitor that
the Local Traffic Manager provides. This type of monitor verifies the RADIUS service by attempting to
authenticate the specified user.
You can test a custom monitor configuration against a specified target destination by using the run command,
and view the results of such a test by using the show command with the test-result option.
The following user roles (in addition to the root user) have permissions to run and stop an ltm monitor test:
admin, application-editor, manager, operator, resource-admin
EXAMPLES
create radius my_radius defaults-from radius
Creates a monitor named my_radius that inherits properties from the default RADIUS monitor.
list radius
Displays the properties of all of the RADIUS monitors.
run radius my_radius destination 10.10.10.10:80
Runs a one-shot test of the custom monitor my_radius against a target node at 10.10.10.10:80.
stop radius my_radius
Cancels a one-shot test of the custom monitor my_radius in progress.
show radius my_radius test-result
Displays the result of the most recent one-shot test of the custom monitor my_radius.
OPTIONS
app-service
Specifies the name of the application service to which the monitor belongs. The default value is none.
Note: If the strict-updates option is enabled on the application service that owns the object, you cannot
modify or delete the monitor. Only the application service can modify or delete the monitor.
debug
Specifies whether the monitor sends error messages and additional information to a log file created and
labeled specifically for this monitor. You can use the log information to help diagnose and troubleshoot
unsuccessful health checks. The default value is no.
The options are:
no Specifies that the system does not redirect error messages and additional information related to
this monitor.
yes Specifies that the system redirects error messages and additional information to the
/var/log/monitors/--.log file.
defaults-from
Specifies the name of the monitor from which you want your custom monitor to inherit settings. The
default value is radius.
description
User defined description.
destination
Specifies the IP address and service port of the resource that is the destination of this monitor. The
default value is *:*.
Possible values are:
*:* Specifies to perform a health check on the IP address and port supplied by a pool member.
*:port
Specifies to perform a health check on the server with the IP address supplied by the pool member
and the port you specify.
IP address:port
Specifies to mark a pool member up or down based on the response of the server at the IP address and
port you specify.
This option is required for the command run, unless an IP address and service port are specified in the
destination option for the specified custom monitor.
glob Displays the items that match the glob expression. See help glob for a description of glob expression
syntax.
interval
Specifies, in seconds, the frequency at which the system issues the monitor check when either the
resource is down or the status of the resource is unknown. The default value is 10 seconds.
Important: F5 Networks recommends that when you configure this option and the up-interval option,
whichever value is greater be a multiple of the lesser value to allow for an even distribution of monitor
checks among all monitors.
manual-resume
Specifies whether the system automatically changes the status of a resource to up at the next successful
monitor check. The default value of the manual-resume option is disabled.
Note that if you set the manual-resume option to enabled, you must manually mark the resource as up
before the system can use it for load balancing connections.
name Specifies a unique name for the component. This option is required for the commands create, delete,
modify, run and stop.
nas-ip-address
Specifies the network access server IP address that the system uses to identify itself to the RADIUS
server. With this option, multiple BIG-IP systems can appear as a single network access device to the
RADIUS server. The default value is none.
partition
Displays the administrative partition within which the component resides.
password
Specifies the password if the monitored target requires authentication. The default value is none.
regex
Displays the items that match the regular expression. The regular expression must be preceded by an at
sign (@[regular expression]) to indicate that the identifier is a regular expression. See help regex for
a description of regular expression syntax.
secret
Specifies the secret the monitor must use when contacting the resource. The default value is none.
test-result
Displays the result of the most recent one-shot test of the specified monitor(s), if any such test has
been performed since BIG-IP was started.
time-until-up
Specifies the amount of time, in seconds, after the first successful response before a node is marked up.
A value of 0 (zero) causes a node to be marked up immediately after a valid response is received from the
node. The default value is 0 (zero).
timeout
Specifies the number of seconds the target has in which to respond to the monitor request. The default
value is 31 seconds.
If the target responds within the set time period, it is considered up. If the target does not respond
within the set time period, it is considered down. Also, if the target responds with a RESET packet, the
system immediately flags the target as down without waiting for the timeout interval to expire.
up-interval
Specifies, in seconds, the frequency at which the system issues the monitor check when the resource is
up. The default value is 0 (zero), which specifies that the system uses the value of the interval option
whether the resource is up or down.
Important: F5 Networks recommends that when you configure this option and the interval option, whichever
value is greater be a multiple of the lesser value to allow for an even distribution of monitor checks
among all monitors.
username
Specifies the username, if the monitored target requires authentication. The default value is none.
