SNMP Data Query with snmpget and snmpwalk
A typical query with "snmpget" might look like this (in this, requesting the OID for the BalanceNG version):
snmpget -v1 -c public tklb1 .188.8.131.52.4.1.2771.1.1
Querying (and outputting) the entire BalanaceNG 2.x management information base (MIB) might be performed as follows:
snmpwalk -v1 -c public tklb1 .184.108.40.206.4.1.2771.1
The BALANCENG-MIB.txt file can be copied into the /usr/share/snmp/mibs directory on the client. The following environment is used to inform local tools like snmpget and snmpwalk) where to find the BalanceNG MIB:
The following output clarifies the difference:
$ snmpget -v1 -c public tklb1 .220.127.116.11.4.1.2771.1.1 SNMPv2-SMI::enterprises.2771.1.1 = STRING: "2.228" $ export MIBS=+BALANCENG-MIB $ snmpget -v1 -c public tklb1 .18.104.22.168.4.1.2771.1.1 BALANCENG-MIB::Release = STRING: "2.228"
The following command makes this setting permanent for the current user:
$ echo "mibs +MY-MIB" >> $HOME/.snmp/snmp.conf
