snmpwalk

$ snmpwalk -v3 -l ${noAuthNoPriv} -u ${username} ${ip} ${oid}

try on your machine

This command is used to perform an SNMP walk operation with SNMP version 3 (SNMPv3). SNMP walk is a command used to gather data from SNMP-enabled devices in a hierarchical manner.

Let's break down the command:

snmpwalk: It is the command used to initiate an SNMP walk operation.
-v3: Specifies that SNMP version 3 should be used for the operation.
-l ${noAuthNoPriv}: Specifies the SNMPv3 security level. In this case, it is set to "noAuthNoPriv", meaning there is no authentication or encryption used. It indicates that the communication between the SNMP manager and device does not require a password or any privacy mechanisms.
-u ${username}: Specifies the SNMPv3 username to be used for authentication. The ${username} is a placeholder that needs to be replaced with an actual username.
${ip}: Specifies the IP address or hostname of the SNMP-enabled device. This is the target device from which you want to retrieve SNMP data.
${oid}: Specifies the object identifier (OID) to start the SNMP walk operation at a specific point in the device's hierarchy. The OID is a unique identifier for each managed object in the SNMP MIB (Management Information Base). This allows you to retrieve specific information about a device. The ${oid} is another placeholder that should be replaced with the actual OID.

Overall, this command initiates an SNMP walk operation with SNMPv3, using the specified security level, username, target device IP address, and the starting point in the device's hierarchy (OID) for data retrieval.
