ExtremeWare Software 7.3.0 Command Reference Guide 511
configure slb vip service-check http
configure slb vip <vip name> service-check http {url <url> match-string
[any-content | <alphanumeric string>]}
Description
Configures layer 7 HTTP service checking for a specific virtual server.
Syntax Description
Default
N/A.
Usage Guidelines
This command automatically enables service checking.
The HTTP service check provides a more thorough check than ping check, because the HTTP service
check connects to a specific URL and checks for a specific text string. Extreme Networks recommends
that you create a specific URL dedicated to this check.
Do not include “http://” in the URL. To check a URL beyond the root directory, include the path in the
specified URL. The maximum length of a URL is 255 characters.
To configure the frequency and timeout of service checks, use the following command:
configure slb global service-check
To configure the global parameters, use the following command:
configure slb global http
Example
The following command configures service check to access http://www.checktest.com and look for the
text “test” on the virtual server “httpvip”:
configure slb vip httpvip service-check http url www.checktest.com match-string test
