Some network administrators use snmpwalk to collect data from lots of different OIDs efficiently with a single command, rather than having to poll all OIDs manually with the GET command. Before we look at snmpwalk examples we must first install snmpwalk. On Windows you can install snmpwalk by following these steps:. To use the snmpwalk command all you have to do is enter the command alongside your chosen parameters. For example, you can specify what version of SNMP you want to use to poll a device.
The range of parameters available means there are many ways to use the command. The simplest option would be to specify the SNMP version, community string whether public or private , and IP address you want to poll. You can run an snmpwalk with those parameters by entering the following:. The command will start walking and will list all existing OIDs on the network. Simply add the OID you want to monitor to the command below:. If the connection was successful you will see lots of OID output generated, but if there was a problem you will see a timeout message like the one shown below:.
Whenever you receive an error message double-check to make sure the community string you entered was correct before investigating further to identify the root cause. There are two main ways to combat this: by setting a new timeout -t and default retry count -r. Setting a new timeout will change the default value to determine how long the snmpwalk command will wait for a response from the polled systems. Similarly, setting a retry count will resend the request once a specific timeout value is reached.
You can use the timeout and default retry settings together. Learn More About walk through. Share walk through Post more words for walk through to Facebook Share more words for walk through on Twitter.
