Configuring Probes for Health Monitoring
Commands Available to all Probe Configurations
These commands are common to all probe types:
HTTP Probe
An HTTP probe establishes an HTTP connection to a real server and then sends an HTTP request and
verifies the response. The ip slb probe probe-name http command places the user in HTTP probe
configuration submode.
To configure an HTTP probe, perform this task:
Command Purpose
Router(config-slb-probe)#
interval seconds
Set the interval between probes in seconds (from the end of the
previous probe to the beginning of the next probe)1.
Range = 5–65535
Default = 120 seconds
1. The no form of this command restores the defaults.
Router(config-slb-probe)#
retries retry-count
Set the number of failed probes that are allowed before marking
the server as failed1.
Range = 0–65535
Default = 3
Router(config-slb-probe)#
failed failed-interval
Set the time, in seconds, to wait before probing a failed server1.
Range = 5–65535
Default = 300 seconds
Router(config-slb-probe)# open
open-timeout
Set the maximum time to wait for a TCP connection. This
command is not used for any non-TCP health checks (ICMP or
DNS1).
Range = 1–65535
Default = 10 seconds
Router(config-slb-probe)#
receive receive-timeout
Set the maximum time in seconds to wait for a reply from the
real server1.
Range = 1–65535
Default = 10 seconds
Command Purpose
Step1 Router(config)# ip slb probe
probe-name http
Configure an HTTP probe and enter the HTTP probe
submode1.
Step2 Router(config-slb-probe-http)#
credentials username [password]
Configure basic authentication values for the HTTP SLB
probe1.
