How to snmpwalk a device – walk a device with snmp

By admin On March 17, 2010 · 1 Comment

Searching on goolge there is no easy explanation on how to make an snmpwalk on a device, thus I decided to describe how to walk the snmp tree of a device.

I suggest you to use one of 3 different tools:

snmputil
snmpwalk
snmpbulkwalk.exe

You can find snmputil on this site and snmpwalk and snmpbulkwalk on this site.

Both of the programs need to run via command line CMD. What you need is the IP address of the device, the SNMP community string (at least RO – read only).

The syntax of snmputil is:

Code:

usage:  snmputil [get|getnext|walk] agent community oid [oid ...]
        snmputil trap

let’s say that the device is a Cisco device and has IP address 192.168.12.12 and community string public the command would be:
snmputil walk 192.168.12.12 public 1.3

If you use snmpwalk and the device has snmp V1 the command would be:

snmpwalk -v1 -c public -On 192.168.12.12 1.3

If you use snmpbulkwalk and the device has snmp V2 the command would be:
snmpbulkwalk -v2c -c public -On 192.168.12.12 1.3

It should help.
