NAME¶

fence_ifmib - Fence agent for IF MIB

DESCRIPTION¶

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.

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

-p, --password=[password]

Login password or passphrase

-S, --password-script=[script]

Script to run to retrieve password

-n, --plug=[id]

Physical plug number on device, UUID or identification of machine This parameter is always required.

-b, --snmp-auth-prot=[prot]

Set authentication protocol (MD5|SHA)
