11 To generate the events the device must be assigned a role of either
12 a primary or a secondary Bridge Port. For more information, see
13 "z/VM Connectivity, SC24-6174".
15 When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state
16 of some configured Bridge Port device on the channel changes, a udev
17 event with ACTION=CHANGE is emitted on behalf of the corresponding
18 ccwgroup device. The event has the following attributes:
20 BRIDGEPORT=statechange
21 indicates that the Bridge Port device changed
24 ROLE={primary|secondary|none}
25 the role assigned to the port.
27 STATE={active|standby|inactive}
28 the newly assumed state of the port.
30 When run on HiperSockets Bridge Capable Port hardware with host address
31 notifications enabled, a udev event with ACTION=CHANGE is emitted.
32 It is emitted on behalf of the corresponding ccwgroup device when a host
33 or a VLAN is registered or unregistered on the network served by the device.
34 The event has the following attributes:
36 BRIDGEDHOST={reset|register|deregister|abort}
38 notifications are started afresh, a new host or VLAN is registered or
39 deregistered on the Bridge Port HiperSockets channel, or address
40 notifications are aborted.
43 VLAN ID on which the event occurred. Not included
44 if no VLAN is involved in the event.
47 MAC address of the host that is being registered
48 or deregistered from the HiperSockets channel. Not reported if the
49 event reports the creation or destruction of a VLAN.
52 device bus ID (CSSID, SSID and device number).
63 Note that the `NTOK_*` attributes refer to devices other than the one
64 connected to the system on which the OS is running.
