For more information, see13"z/VM Connectivity, SC24-6174".14 15When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state16of some configured Bridge Port device on the channel changes, a udev17event with ACTION=CHANGE is emitted on behalf of the corresponding18ccwgroup device. The event has the following attributes:19 20BRIDGEPORT=statechange21 indicates that the Bridge Port device changed22 its state.23 24ROLE={primary|secondary|none}25 the role assigned to the port.26 27STATE={active|standby|inactive}28 the newly assumed state of the port.29 30When run on HiperSockets Bridge Capable Port hardware with host address31notifications enabled, a udev event with ACTION=CHANGE is emitted.32It is emitted on behalf of the corresponding ccwgroup device when a host33or a VLAN is registered or unregistered on the network served by the device.34The event has the following attributes:35 36BRIDGEDHOST={reset|register|deregister|abort}37 host address38 notifications are started afresh, a new host or VLAN is registered or39 deregistered on the Bridge Port HiperSockets channel, or address40 notifications are aborted.41 42VLAN=numeric-vlan-id43 VLAN ID on which the event occurred.
