SNMP-BRIDGE-MIB(1)			     Net-SNMP			       SNMP-BRIDGE-MIB(1)

NAME
       snmp-bridge-mib - provide Linux bridge information via SNMP

SYNOPSIS
       snmp-bridge-mib {bridge}

ARGUMENTS
       The following arguments are required:

       bridge
	   The name of the Linux bridge for which you want to provide information via SNMP, e.g.
	   br0.

DESCRIPTION
       The snmp-bridge-mib is an extension to net-snmp. It collects information about a bridge in
       a Linux system and exports them for query from other (remote) systems for management
       purposes.

CONFIGURATION:
       The preferred method of snmp-bridge-mib to attach to net-snmp is agentx. For this to work,
       you will have to add the following line to /etc/snmp/snmpd.conf,

	       master agentx

       restart snmpd and start snmp-bridge-mib. snmp-bridge-mib will then connect to the running
       snmpd daemon.

       Another way of attaching snmp-bridge-mib to is to run it as an embedded perl module. You
       have to add

	       perl do "path to location of snmp-bridge-mib"

       and restart snmpd.

EXAMPLE:
       Follow the instructions in this manpage and type

	       perl /usr/bin/snmp-bridge-mib br0

       You'll get the following output:

		registering at .1.3.6.1.2.1.17
		running as a subagent.
		dot1qbridge agent started.
		NET-SNMP version 5.4.2.1 AgentX subagent connected

       Now it's time for a first test:

	       $ export MIBS=+BRIDGE-MIB
	       $ snmpwalk localhost .1.3.6.1.2.1.17

       The output produced should look like

	       BRIDGE-MIB::dot1dTpPortInDiscards.3 = Counter32: 0 frames

BUGS
	1. snmp-bridge-mib currently only supports one bridge which has to be specified on the
	   commandline.

	2. Not all elements of RFC 4188 because they are either not available in sysfs or
	   difficult to extract from the existing data.
