snmp-bridge-mib1
Provide linux bridge information via snmp
Usage
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.
Overview
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
