1. Overview
------------
  SNMP is  a unified protocol  of network monitoring  and network  device
  management.  All active  network  devices  support SNMP.  Besides  that,
  SNMP is supported  by major operational  systems and a large  number of
  network applications.

  SnmpWalk allows you to detect a set of variables that are available for
  reading  on a certain device. You can obtain  a full list  or just part.
  By  analyzing  the  results  of a network  device  scan  obtained  with
  SnmpWalk  you  can develop a list  of supported MIBs  and,  in this way,
  obtain full descriptions of variables and possible values. Besides that,
  MIB  documents  contain  information  about  SNMP  variables  that  are
  available only for writing.  After analyzing information retrieved with
  SnmpWalk  from hardware  or software SNMP sources,  you can use SnmpSet
  and SnmpGet tools to change and obtain values.

  The value  of SnmpWalk  is  not limited  to only  the SNMP analysis  of
  supported features.  This tool can effectively  obtain SNMP tables  and
  read whole sections  of variables.  This particularly  refers to tables
  that are  often used for presenting statistical  and status information.

  SnmpWalk  is  a command-line  tool,  which  makes  possible  its use in
  scripts.  This tool  supports modern IPv6  in addition to  the standard
  IPv4.  Moreover,  SnmpWalk  allows  you  to  use  a simple  version  of
  SNMPv1/SNMPv2c and also supports a safe version of SNMPv3.
  

2. Features

What is SNMP?

SNMP also known as “Simple Network Management Protocol” is an application-layer protocol used to measure and monitor the performance of the devices within a network. It helps the system administrator to ensure that networks stay up and running. Today, SNMP is one of the most popular networking protocols in the world. All modern manufacturers create SNMP-enabled devices that enterprises can use to obtain performance data from the devices.

How SNMP Works?

SNMP uses the device’s Management Information Database (MIB) to collect the performance data. The MIB is a database that records information about the hardware and contains MIB files. The MIB resides within the SNMP manager designed to collect information and organize it into a hierarchical format. SNMP uses this information from the MIB to interpret messages before sending them onwards to the end-user.

There are different types of queries managers used to poll the information from the SNMP agent including, GET or GET-NEXT commands. The GET command uses the agent’s hostname and Object Identifiers (OID) to obtain the information from the MIB. The GET-NEXT command obtains the data from the next OID.

What is SNMPWALK?

SNMPWALK is a command-line utility used to collect the information from remote SNMP-enabled devices including, routers and switches. It allows you to see all the OID variables available on remote devices. It sends multiple GET-NEXT commands to OIDs then the manager collects the data from all OIDs. SNMPWALK is a command-line utility that can be installed on Linux and Windows operating systems.

In this guide, we will show you how to install SNMPWALK on Windows and Linux. We will also explain how to use it to get the information from the remote devices.

Install SNMP and SNMPWALK on Linux

In this section, we will show you how to install SNMP and SNMPWALK on Debian and RPM-based Linux operating systems.

For RPM-based operating system including, RHEL/CentOS/Fedora, install the SNMP and SNMPWALK using the following command:

yum install net-snmp net-snmp-libs net-snmp-utils -y

For Debian based operating system including, Debian/Ubuntu, install the SNMP and SNMPWALK using the following command:

apt-get install snmpd snmp libsnmp-dev -y

Once the installation has been finished, start the SNMP service and enable it to start at system reboot with the following command:

systemctl start snmpd
systemctl enable snmpd

You can check the status of the SNMP with the following command:

systemctl status snmpd

You should get the following output:

● snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
Loaded: loaded (/lib/systemd/system/snmpd.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2021-05-14 06:36:48 UTC; 3min 22s ago
Main PID: 36724 (snmpd)
Tasks: 1 (limit: 4691)
Memory: 8.7M
CGroup: /system.slice/snmpd.service
└─36724 /usr/sbin/snmpd -LOw -u Debian-snmp -g Debian-snmp -I -smux mteTrigger mteTriggerConf -f -p /run/snmpd.pid

May 14 06:36:48 ubuntu2004 systemd[1]: Started Simple Network Management Protocol (SNMP) Daemon..

By default, SNMP does not allow retrieving all available SNMP information. So you will need to edit the SNMP default configuration file and make some changes so we can retrieve all information using the SNMPWALK command.

nano /etc/snmp/snmpd.conf

Find the following lines:


rocommunity public default -V systemonly
rocommunity6 public default -V systemonly

And, replace them with the following lines:

rocommunity public default
rocommunity6 public default

Save and close the file then restart the SNMP service to apply the changes:

systemctl restart snmpd

Now, open your command-line interface and print help information of SNMPWALK command as shown below:

snmpwalk -h

You should get the following output:

SNMPWALK FAQs

What is a snmpwalk tool?

SNMPWALK is a process of exploring the Management Information Base (MIB) structure of an SNMP report. The MIB has a tree structure that is denoted by a dot-notation number and the “walk” crawls through these numbers, recreating the tree. An SNMPWALK tool can construct a MIB tree by mapping the relationship between the values in a MIB. Each number that identifies a node on the MIB tree will have a label and a value. The OID (Object ID) is a reference code for the label.

Is SNMP v3 TCP or UDP?

All versions of SNMP use the same ports – there are two and they are both UDP. Regular SNMP transactions involve the SNMP Manager sending out a broadcasted request, to which the SNMP device agents reply with a MIB. This communication occurs on UDP port 161. The SNMP agent can send out a warning message without waiting for a request. This is called a Trap and it goes to UDP port 162.

What is OID in Linux?

OID is short for Object ID. It is the level code that identifies a node in a tree structure that is used for reporting in SNMP. An SNMP report is called a Management Information Base (MIB). It has a set number of fields that are identified by OIDs. The OID uses a dot-notation format to indicate the inheritance of a node on the tree.
