Fence Agents for Red Hat Cluster - IF-MIB SNMP agent

 Red Hat Fence Agents is a collection of scripts to handle remote power
 management for several devices. They allow failed or unreachable nodes to be
 forcibly restarted and removed from the cluster.
 .
 fence_ifmib is an I/O Fencing agent which can be used with any SNMP IF-MIB
 capable device.
 .
 It was written with managed ethernet switches in mind, in order to fence iSCSI
 SAN connections. However, there are many devices that support the IF-MIB
 interface. The agent uses IF-MIB::ifAdminStatus to control the state of an
 interface.
