Configuring Probes for Health Monitoring
After you configure a probe, associate single or multiple probes with a server farm. All servers in the
server farm receive probes of the probe types that are associated with that pool.
Note If you associate a probe of a particular type with a server farm containing real servers that are not
running the corresponding service, the real servers send error messages when they receive a probe of
that type.
To specify a probe type and name, perform this task:
Note When you specify a probe name and type, it is initially configured with the default values. Enter the
probe configuration commands to change the default configuration.
This example shows how to configure a probe:
Router(config)# ip slb probe probe1 tcp
Router(config-slb-probe-tcp)# interval 120
Router(config-slb-probe-tcp)# retries 3
Router(config-slb-probe-tcp)# failed 300
Router(config-slb-probe-tcp)# open 10
Router(config-slb-probe-tcp)# receive 10
Command Purpose
Router(config)# ip slb probe
probe-name [http | icmp |
telnet | tcp | ftp | smtp |
dns]
Specify a probe type and a name1.
•probe-name is the name of the probe being configured; it has
a character string of up to 15 characters.
•http creates an HTTP probe with a default configuration.
•icmp creates an ICMP probe with a default configuration.
•telnet creates a Telnet probe with a default configuration.
•tcp creates a TCP probe with a default configuration.
•ftp creates an FTP probe with a default configuration.
•smtp creates an SMTP probe with a default configuration.
•dns creates a DNS probe with a default configuration.
1. The no form of this command removes the probe type from the configuration.
Router# show ip slb probe Display all probes and their configuration.
