11.4. Naming Scheme for Network Devices Available for Linux on System z
Use the bus-ID to create predictable device names for network interfaces in Linux on System z instances. The bus-ID identifies a device in the s390 channel subsystem. A bus ID identifies the device within the scope of a Linux instance. For a CCW device, the bus ID is the device's device number with a leading
0.n, where n is the subchannel set ID. For example, 0.1.0ab1.
Network interfaces of device type Ethernet are named as follows:
enccw0.0.1234
CTC network devices of device type SLIP are named as follows:
slccw0.0.1234
Use the
znetconf -c command or the lscss -a command to display available network devices and their bus-IDs.
