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
Step 1
Router(config)# ip slb probe
probe-name http
Step 2
Router(config-slb-probe-http)#
credentials username [password]
