BIG-IP may fail to update configuration of a virtual server when disabling or enabling spanning on the virtual address.


Disabling or enabling spanning on a virtual address has no effect on the virtual-server configuration. Depending on the configuration, virtual server may or may not forward the traffic when expected.


Spanning is disabled or enabled on a virtual address.


Enable/Disable spanning together with changing a traffic-group (both options have to be changed simultaneously): > modify ltm virtual-address traffic-group traffic-group-2 spanning disabled > modify ltm virtual-address traffic-group traffic-group-1 spanning enabled
