A virtual server stops DNS response and its status on GUI is yellow.


Virtual server stops all DNS response, and the virtual server state in the GUI turns yellow. Yellow is intended to signify that the virtual server is serving connections but should not receive any further traffic until it goes green. In this case, however, yellow indicates that traffic is OK, as long as it is not from a given client (or to a given destination).


-- LTM virtual server (or Pool Member or Node) is over the limit. -- The Connection Rate Limit Mode is rate limited by source or destination.



Fix Information

A new variable, Ignore LTM Rate Limit Modes, has been added to allow optionally ignoring LTM virtual server yellow state caused by connection/rate limit reached in GUI. It can be found in DNS :: Settings : GSLB : General.
