b4d72c08 EC |
10 | |
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". | |
14 | ||
9c23f4da | 15 | When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state |
b4d72c08 EC |
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: | |
19 | ||
8b4a503d MCC |
20 | BRIDGEPORT=statechange |
21 | indicates that the Bridge Port device changed | |
b4d72c08 EC |
22 | its state. |
23 | ||
8b4a503d MCC |
24 | ROLE={primary|secondary|none} |
25 | the role assigned to the port. | |
b4d72c08 | 26 | |
8b4a503d MCC |
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: | |
35 | ||
8b4a503d MCC |
36 | BRIDGEDHOST={reset|register|deregister|abort} |
37 | host address | |
9f48b9db EC |
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 | ||
8b4a503d MCC |
42 | VLAN=numeric-vlan-id |
43 | VLAN ID on which the event occurred. Not included | |
9f48b9db EC |
44 | if no VLAN is involved in the event. |
45 | ||
8b4a503d MCC |
46 | MAC=xx:xx:xx:xx:xx:xx |
47 | MAC address of the host that is being registered | |
9f48b9db EC |
48 | or deregistered from the HiperSockets channel. Not reported if the |
49 | event reports the creation or destruction of a VLAN. | |
50 | ||
8b4a503d MCC |
51 | NTOK_BUSID=x.y.zzzz |
52 | device bus ID (CSSID, SSID and device number). | |
9f48b9db | 53 | |
8b4a503d MCC |
54 | NTOK_IID=xx |
55 | device IID. | |
9f48b9db | 56 | |
8b4a503d MCC |
57 | NTOK_CHPID=xx |
58 | device CHPID. | |
9f48b9db | 59 | |
8b4a503d MCC |
60 | NTOK_CHID=xxxx |
61 | device channel ID. | |
9f48b9db | 62 | |
8b4a503d | 63 | Note that the `NTOK_*` attributes refer to devices other than the one |
9f48b9db | 64 | connected to the system on which the OS is running. |
