# Using OID netSnmpExampleHeartbeatRate (1.3.6.1.2.3.2.1) to send a trap using MIB If you prefer the GUI version of SNMPwalk on Windows please check out SnmpB MIB browser instead to test SNMP and manage MIB files on Windows.īefore you continue, make sure that the host or network firewall is not blocking UDP port 161.Įxamples # Using OID netSnmpExampleHeartbeatRate (1.3.6.1.2.3.2.1) to send a trap using numeric OID On Windows, download and install net-snmp-5.5.0-2.圆4.exe, leave default directory “ C:\usr“, then run the CMD tool and when calling snmpwalk tool use a full path like this “ C:\usr\bin\snmpwalk.exe -v2c -c public localhost 1.3.6.1.2.1.1“ On Ubuntu/Debian/Rasbian you can install Net-SNMP tools with one simple command: “ apt-get install snmp“, or if you have CentOS/RHEL/Oracle Linux/Fedora you can use “ yum install net-snmp net-snmp-utils“. However, if you have a basic understanding of SNMP then continue with reading.
In this tutorial, I will show you how to use that command using various snmpwalk examples (v3 and v2c), and also examples of other commands from the Net-SNMP toolkit: SnmpGet, SnmpSet, and SnmpTrap.Īre you familiar with the SNMP protocol? No? Don’t worry, I got you covered with my post – What is SNMP protocol? How does it work? Learn with examples. The snmpwalk command is one of the most used tools on Linux and Windows for testing SNMP on the network devices.
