How to Use SNMPWALK to Retrieve the System Information
In this section, we will show you how to use the SNMPWALK command in Linux to retrieve the system information.
You can use the following options with the SNMPWALK command to retrieve system information, this with snmp version 1 and 2:
- -v: Specify the SNMP version.
- -c: Specify the community string which you have configured on the SNMP.
- hostname: Specify the hostname or IP address of the system where the SNMP agent is installed.
- OID: Specify the OID to return all SNMP objects.

The following example CLI command will return the IPS temperature information:
Command:snmpwalk -v 2c -c tinapc <IP address> 1.3.6.1.4.1.10734.3.5.2.5.5
Command Explanation:
In this case the CLI command breaks down as following;
snmpwalk = SNMP application
-v 2c = specifies what SNMP version to use (1, 2c, 3)
-c tinapc = specifies the community string. Note: The IPS has the SNMP read-only community string of "tinapc"
<IP address> = specifies the IP address of the IPS device
1.3.6.1.4.1.10734.3.5.2.5.5 = OID parameter for the IPS temperature information
Results:
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.1.0 = INTEGER: 27
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.2.0 = INTEGER: 50
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.3.0 = INTEGER: 55
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.4.0 = INTEGER: 0
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.5.0 = INTEGER: 85
Results Explanation:
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.1.0 = INTEGER: 27 = The chassis temperature (27° Celsius / 80.6° Fahrenheit)
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.2.0 = INTEGER: 50 = The major threshold value for chassis temperature (50° Celsius / 122° Fahrenheit)
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.3.0 = INTEGER: 55 = The critical threshold value of chassis temperature (55° Celsius / 131° Fahrenheit)
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.4.0 = INTEGER: 0 = The minimum value of the chassis temperature range ( 0° Celsius / 32° Fahrenheit)
SNMPv2-SMI::enterprises.10734.3.5.2.5.5.5.0 = INTEGER: 85 = The maximum value of the chassis temperature range (85° Celsius / 185° Fahrenheit) |
