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.
