Do you know what is snmp? if you have not any idea about SNMP then go-through our blog what is snmp command.


In this blog, We will show you quick and clear examples on how you can use snmpwalk command



SNMPWALK command


Snmpwalk uses the “SNMP GETNEXT” message type to collect multiple information from a network device in a single SNMP query.



snmpwalk v3 example


Examples


# snmpwalk v3 example with authentication and encryption


snmpwalk -v3 -l authPriv -u UserMe -a SHA -A AuthPass1 -x AES -X PrivPass2 192.168.1.1:161 1.3.6.1.2.1.1


# snmpwalk v3 example with authentication, but no encryption


snmpwalk -v3 -l authPriv -u UserMe -a SHA -A AuthPass1 192.168.1.1:161 1.3.6.1.2.1.1


# snmpwalk v3 example with no authentication and no encryption but you still needs a username


snmpwalk -v3 -l noAuthNoPriv -u UserMe 192.168.1.1:161 1.3.6.1.2.1.1


# Using OID dot1dTpFdbAddress and SNMPv3 context name to get mac addresses in VLAN 32


snmpwalk -v3 -l authNoPriv -u UserMe -a MD5 -A AuthPass1 -n vlan-32 192.168.1.1 dot1dTpFdbAddress


Syntax:


snmpwalk -v3 -l <noAuthNoPriv|authNoPriv|authPriv> -u <username> [-a <MD5|SHA>] [-A <authphrase>]

[-x <DES|AES>] [-X <privaphrase>] <ipaddress>[:<dest_port>] [oid]



snmpwalk v2c example


Examples


# Using OID system (1.3.6.1.2.1.1) to get basic system information about host

snmpwalk -v2c -c public 192.168.1.1:161 1.3.6.1.2.1.1


Syntax:


snmpwalk -v2c -c <community> <ipaddress>[:<dest_port>] [oid]


SNMPGET command


A snmpget command is same as snmpwalk, just replace “snmpwalk” with “snmpget” when you run the command like this:


# Using OID sysDescr (1.3.6.1.2.1.1.1) to get system description


snmpget -v3 -l authPriv -u UserMe -a SHA -A AuthPass1 -x AES -X PrivPass2 10.1.1.1 1.3.6.1.2.1.1.0

What is STP? - Explain Advantages and Disadvantages

The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. STP is a protocol. It actively monitors all links of the network. To finds a redundant link, it uses an algorithm, known as the STA (spanning-tree algorithm). The STA algorithm first creates a topology database then it finds and disables the redundant links. Once redundant links are disabled, only the STP-chosen links remain active. If a new link is added or an existing link is removed, the STP re-runs the STA algorithm and re-adjusts all links to reflect the change. STP (Spanning Tree Protocol) automatically removes layer 2 switching loops by shutting down the redundant links. A redundant link is an additional link between two switches. A redundant link is usually created for backup purposes. Just like every coin has two sides, a redundant link, along with...
