Severity: 4-Minor


If iRule with HTML commands inside is attached to Virtual server which has not HTML profile, this iRule may fail with 'Unknown error' message in the log.


iRule does not work as expected


- iRule with HTML commands - Virtual server without HTML profile - the iRule is attached to this server


If Virtual server uses iRule with HTML commands, this server should use HTML profile.

Fix Information

If BIGIP configuration contains iRule with HTML commands which is used by Virtual server without HTML profile, then the following error is logged at configuration load time: HTML::<command name> in rule (<rule name>) requires an associated HTML profile on the virtual server (<server name>)

Behavior Change

BIGIP configuration can not be loaded if it contains: - iRule with HTML command(-s) inside AND - Virtual server without HTML profile which uses this iRule.
