Unexpected traffic handling and disruption
Changing virtual-server configuration when using traffic-matching-criteria.
Avoid using TMC (port lists and address lists). When in a 'faulty' state you can try changing vlan-enabled on and changing it back on the virtual server, you might need to clear existing connections afterwards. Follow below articles.
