NAME

fence_ifmib - I/O Fencing agent for IF-MIB capable SNMP devices

SYNOPSIS

fence_ifmib [OPTION]...

DESCRIPTION

fence_ifmib is an I/O Fencing agent which can be used with any IF-MIB capable SNMP 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.

OPTIONS

-a IPaddress

IP address or hostname of the SNMP agent to be written.

-h

Print out a help message describing available options, then exit.

-c community

The write community string to be used in the request.

-i iIindex

The ifIndex of the interface to be acted upon. This will need to be determined manually prior to configuration.

-o action

The action required. off (default), on, or status. off sets ifAdminStatus down, on sets ifAdminStatus up, and status returns the current state.

-V

Verbose. Print informational messages to standard out.
