462 ExtremeWare Software 7.3.0 Command Reference Guide
SLB Commands
configure slb global http
configure slb global http url <url> match-string [any-content |
alphanumeric string]
Description
Configures the default parameters for layer 7 HTTP service checking.
Syntax Description
Default
The default value for url is /.
The default match string is any content.
Usage Guidelines
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 enable service checking, use the following command:
enable slb vip <vip name> service-check
To configure the frequency and timeout of service checks, use the following command:
configure slb global service-check
To configure the parameters for a specific virtual server, use the following command:
configure slb vip <vip name> service-check ftp
Example
The following command configures service check to access http://www.checktest.com and look for the
text “test”:
configure slb global http url www.checktest.com match-string test
