Running ifup ib-interface or service network restart reports the following error:

/etc/sysconfig/network-scripts/ifup-ib: line 357: /sys/class/net/ib0/acl_enabled: Permission denied

This error is reported, even though the InfiniBand interface is brought up successfully.

The workaround for this issue is to change from using the older configuration method, where you manipulate sysfs files to the newer ibacl tools that are provided. (Bug ID 26197105)
