Hi All: I am working on bug [1] removing "link capacity of interface" configuration in config_controller, config_validator and config_gui. Reason: the link capacity is set to 10G only when doing traffic control[2], it is unnecessary to input 'link capacity' during controller configure. Impact: 1) all 'link capacity' related configure input option is removed. 2) it is compatibility with old *.ini configure file: when "INTERFACE_LINK_CAPACITY=10000", it is compatible. For other values, you will see following errors: "Invalid link-capacity value for XXX". Relax. Just edit "INTERFACE_LINK_CAPACITY" to 10000 and retry "config_controller". Feel free to reply if you any idea about this. Any response is welcome. [1] https://bugs.launchpad.net/starlingx/+bug/1805320 [2] https://storyboard.openstack.org/#!/story/2003087 Thanks Ran
