Summary:
This article demonstrates how to get an OID to monitor the PMP450 radios.
Solution:
The free iReasoning MIB browser is a convenient way to explore the MIB file and find out the OIDs for almost all the parameters of the PMP radio.
iReasoning MIB browser is a powerful and easy-to-use tool, powered by iReasoning SNMP API which helps to manage SNMP enabled network devices and applications. It allows users to load standard, proprietary MIBs, and even some mal-formed MIBs. It also allows them to issue SNMP requests to retrieve agent's data, or make changes to the agent.
Please download the iReasoning software from the below link and install it the Laptop/PC

Download the MIB files (PMP450x MIBS) of PMP450 radios from the below link:
https://support.cambiumnetworks.com/files/pmp450/
It is recommended to use the MIB version similar to the PMP450 radio software version.
Below is the MIB file for the latest software version 16.1.
For example: To see or monitor, the “max range” and “channel bandwidth” configured on the radio and if needed to change the channel bandwidth of the radio, please follow the below steps and get the OID values.
Step-1:
Double click on the iReasoning software Icon and the below window will appear. If you load the PMP450x MIB file into a browser, you can view the MIB as a tree structure.
Step-2:
Load the MIB files by navigating to File>>Load MIBs and unload the MIBs if there is any existing.
Step-3:
Select all the MIB Files present in the MIB folder and upload into the iReasoning tool.
Step-4:
Once you load the MIB files, you will see a folder shown below which contains all the OIDs of the radio parameters.
Step-5:
Configure the IP address of the radio which you want to monitor through SNMP and click on advance properties to configure the SNMP Port (Default port-16) and read/write community string configured on the PMP450 radio.
Step-6:
Make sure the read/write option is checked and community strings are configured correctly on the radio and iReasoning tool advance settings.
Step-7:
Use CTRL+F to open a window shown below and enter the variable like “maxrange” without any space and uncheck the box (Match whole word only) below it and click on “find next” to get the max range. Double click on the “maxrange” to get the OID and max range value highlighted below:
Step-8:
Use CTRL+F to open a window as step-7 and enter the variable like “channelbandwidth” without any space and uncheck the box (Match whole word only) below it and click on “find next” until you get the desired “channel bandwidth” parameter. Double click on the “Channelbandwidth” to get the OID and channel bandwidth value configured on the radio and choose the operation “set” to change the value.
Step-9:
Once you Double click on the “Channelbandwidth” to get the OID and channel bandwidth value configured on the radio and choose the operation “set” to change the value suppose from 30 MHz to 20 MHz. Make sure you select the correct data type which we need to enter in the “value” field, depending on the parameter you want to change.
