NAME¶

ifcfg-ipoib - Infiniband interface configuration

SYNOPSIS¶

/etc/sysconfig/network/ifcfg-*

Infiniband/IPoIB Interfaces¶

To identify an interface configuration as Infiniband/IPoIB you either need a config file with the IPOIB=yes variable set or one using a config file name ifcfg-ibN or ifcfg-ibN.XXXX (e.g. ifcfg-ib0 or ifcfg-ib0.8001).

IPOIB <yes|no>

This option must be set to yes to identify this configuration as Infiniband/IPoIB, regardless of the configuration file name.

IPOIB_DEVICE

Used to create a child-/sub-interface of the given physical Infiniband interface with partition key as specified in IPOIB_PKEY section. The physical infiniband interface name is also read from the ifcfg-ibN.XXXX config file name, but the IPOIB_DEVICE variable has precedence.

IPOIB_PKEY

Specify the partition key of the child-/sub-subinterface. The child-/sub-interface will be created if it does not exists. The partition key is also extracted from the ifcfg-ibN.XXX config file name, but the IPOIB_PKEY variable has precedence.

IPOIB_MODE

Configure the transport mode of the Infiniband interface by setting this variable to connected (CM - Connected Mode) or datagram (UD - Unreliable Datagram).

IPOIB_UMCAST

Configure the user-multicast permission of the Infiniband interface by setting this variable to allowed or disallowed.

EXAMPLE¶

Examples of Infiniband/IPoIB interface config files:

ifcfg-ib0

IPOIB=yes
STARTMODE=auto
BOOTPROTO=static
IPADDR=10.0.0.100/24
    

ifcfg-ib0.8001

IPOIB=yes
STARTMODE=auto
BOOTPROTO=dhcp
    

ifcfg-custom1

IPOIB=yes
IPOIB_DEVICE=ib0
IPOIB_PKEY=8002
STARTMODE=auto
BOOTPROTO=dhcp
