fence_ifmib (8)

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.

fence_ifmib accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_ifmib can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
