1. Configuring NMS to monitor the RSSI of 615M 1 cellular modem routers Technical Application Note Purpose This application note describes how to configure the Network Management System NMS to monitor the received signal strength RSSI of 615M 1 routers You may need to monitor RSSI to find out why a 615M is dropping connections Monitoring can reveal that the 615M has poor RF reception in some areas or interference from other devices at particular times conditions that may cause unstabile connections The 615M has built in SNMP functionality for remote monitoring and NMS can track and monitor devices over time This combination provides a powerful solution for monitoring RSSI Data is reported systematically and graphically allowing you to quickly identify the cause of a signal strength issue Before you begin This document assumes that you have already installed and configured NMS version 1 0 7 or earlier and have added the 615M devices you want to monitor to the NMS system For installation and setup instructions refer to the NMS installation guide and the NMS quick start guide Figure 1 Configuration Setup PC running NMS virtual machine Ethernet connection 615M 1 Cellular 615M 1 Cellular Modem and Modem and Router Router E N Powering Business Worldwide Ethernet connection wired or wireless To configure NMS to monitor RSSI you need e PC with Ethernet or wireless network access2. a Open VMware Player b On the Virtual Machine menu click Virtual Machine Settings c Click the Option tab and then click Shared Folders in the Settings column d Verify the following folder settings e Under Folder Sharing make sure that the Always enabled option is selected e Under Folders make sure that the check box for the CooperNMS folder is selected Log on to the NMS virtual machine a From the main VMware Player window click the cooperNMSvx x x image on the left b Click Play virtual machine c At the localhost login type root and press Enter and then type the password cooperadmin and press Enter For detailed instructions on running the NMS virtual machine see the NMS installation guide Enter the following command to change the directory to the mibfiles shared directory cd mnt hgfs mibfiles Enter the following command to list the directory contents Verify that the MIB file appears in the list 1s Enter the following command to install the MIB file in this example 615 5 0 2 A final txt into the NMS Linux system addmib addmib addmib 615 5 0 2 A final txt The SNMP OID entries are now ready to use for 615M RSSI monitoring Setting up and testing email and SMS notification In this step you will set the notification options in NMS to receive alerts when a problem is detected during RSSI monitoring There are two notification options S
