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::dot1dStpBridgeHelloTime = INTEGER: 199 centi-seconds

	       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.
