Queens Series Release Notes¶
Added new param for puppet to set ovn_openflow_probe_interval which is inactivity probe interval of the OpenFlow connection to the OpenvSwitch integration bridge, in seconds. If the value is zero, it disables the connection keepalive feature, by default this value is set on 60s. If the value is nonzero, then it will be forced to a value of at least 5s.
This parameter sets inactive probe interval of the JSON session from ovn-controller to the OVN SB database. By default this it is 5s which not be sufficient in loaded systems or during high control-plane activity spikes, leading to unnecessary reconnections to OVSDB server. Now it is extended by default to 1 min and it is configurable.
