1SNMP-BRIDGE-MIB(1) Net-SNMP SNMP-BRIDGE-MIB(1)
2
6 snmp-bridge-mib - provide Linux bridge information via SNMP
7
9 snmp-bridge-mib {bridge}
10
12 The following arguments are required:
13 bridge
15 The name of the Linux bridge for which you want to provide
16 information via SNMP, e.g. br0.
17
19 The snmp-bridge-mib is an extension to net-snmp. It collects
20 information about a bridge in a Linux system and exports them for query
21 from other (remote) systems for management purposes.
22
24 The preferred method of snmp-bridge-mib to attach to net-snmp is
25 agentx. For this to work, you will have to add the following line to
26 /etc/snmp/snmpd.conf,
27 master agentx
29 restart snmpd and start snmp-bridge-mib. snmp-bridge-mib will then
32 connect to the running snmpd daemon.
33 Another way of attaching snmp-bridge-mib to is to run it as an embedded
35 perl module. You have to add
36 perl do "path to location of snmp-bridge-mib"
38 and restart snmpd.
41
43 Follow the instructions in this manpage and type
44 perl /usr/bin/snmp-bridge-mib br0
46 You´ll get the following output:
49 registering at .1.3.6.1.2.1.17
51 running as a subagent.
52 dot1qbridge agent started.
53 NET-SNMP version 5.4.2.1 AgentX subagent connected
54 Now it´s time for a first test:
57 $ export MIBS=+BRIDGE-MIB
59 $ snmpwalk localhost .1.3.6.1.2.1.17
60 The output produced should look like

107 1. snmp-bridge-mib currently only supports one bridge which has to be
108 specified on the commandline.
109 2. Not all elements of RFC 4188 because they are either not available
111 in sysfs or difficult to extract from the existing data.
