💖 ifcfg-ipoib(5) 💖

okay bestie, welcome to the Wicked User Manual page for Infiniband interface configuration — yes, the manual name is folded in right here, cute and cozy 🫶

✨ NAME ✨

ifcfg-ipoib — Infiniband interface configuration. That's the whole vibe: this is the page for setting up Infiniband/IPoIB interface configs. 💅

✨ 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). No cap, that's the whole identification situation. ✨

  • IPOIB <yes|no> — this one must be set to yes to identify this configuration as Infiniband/IPoIB, regardless of the configuration file name. Literally required, bestie. 💖
  • IPOIB_DEVICE — used to create a child-/sub-interface of the given physical Infiniband interface, with the partition key as specified in the 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 — specifies 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 — configures the transport mode of the Infiniband interface. Set this variable to connected (CM - Connected Mode) or datagram (UD - Unreliable Datagram). ⭐
  • IPOIB_UMCAST — configures the user-multicast permission of the Infiniband interface. Set this variable to allowed or disallowed. 🦋

🍓 EXAMPLE 🍓

Examples of Infiniband/IPoIB interface config files — here they are, looking iconic:

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
