Description

Syntax Description

Usage Guidelines
This command automatically enables HTTP check. The HTTP requests the designated URL from each
next hop specified in the flow redirection policy and checks for the specified alphanumeric string in the
first 5000 bytes. 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.
For ExtremeWare 6.2.0 and prior, the frequency of the HTTP check is 60 seconds, the timeout of the
HTTP check is 180 seconds, and you cannot configure these times.
For ExtremeWare 6.2.1 and later, configure the frequency and timeout using the following command:
configure flow-redirect timer service-check
Example
The following command configures (and enables) HTTP check for the flow redirection policy named
“http_flow” and checks http://www.checktest.com for the string “test”:
configure flow-redirect http_flow service-check http url www.checktest.com
match-string test
