IB Bonding
Interface Configuration Scripts
Create interface configuration scripts for the ibX and bondX interfaces. Once the
configurations are in place, perform a server reboot, or a service network restart.
For SLES operating systems (OS), a server reboot is required. Refer to the
following standard syntax for bonding configuration by the OS.
NOTE:
For all of the following OS configuration script examples that set MTU,
MTU=65520 is valid only if all IPoIB slaves operate in connected mode and
are configured with the same value. For IPoIB slaves that work in datagram
mode, use MTU=2044. If the MTU is not set correctly or the MTU is not set
at all (set to the default value), performance of the interface may be lower.
