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

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.
