      8Uevents
      9-------
     10
     11To generate the events the device must be assigned a role of either
     12a primary or a secondary Bridge Port. For more information, see
     13"z/VM Connectivity, SC24-6174".
     14
     15When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state
     16of some configured Bridge Port device on the channel changes, a udev
     17event with ACTION=CHANGE is emitted on behalf of the corresponding
     18ccwgroup device. The event has the following attributes:
     19
     20BRIDGEPORT=statechange
     21  indicates that the Bridge Port device changed
     22  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 address
     31notifications enabled, a udev event with ACTION=CHANGE is emitted.
     32It is emitted on behalf of the corresponding ccwgroup device when a host
     33or 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 address
     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.
     41
     42VLAN=numeric-vlan-id
     43  VLAN ID on which the event occurred. Not included
     44  if no VLAN is involved in the event.
     45
     46MAC=xx:xx:xx:xx:xx:xx
     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.
     50
     51NTOK_BUSID=x.y.zzzz
     52  device bus ID (CSSID, SSID and device number).
     53
     54NTOK_IID=xx
     55  device IID.
     56
     57NTOK_CHPID=xx
     58  device CHPID.
     59
     60NTOK_CHID=xxxx
     61  device channel ID.
     62
     63Note that the `NTOK_*` attributes refer to devices other than  the one
     64connected to the system on which the OS is running.
