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

       The following arguments are required:

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

        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.

       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.

http://www.ibm.com/ v6                             26 Mar 2010                                SNMP-BRIDGE-MIB(1)

       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.

       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
