APPENDIX D
Simple Network Management 
Protocol (SNMP) 
The PinPoint can be configured as an SNMP agent and supports SNMPv2c and SNMPv3.  
SNMP Overview
The Simple Network Management Protocol (SNMP) was designed to allow remote management 
and monitoring of a variety of devices from a central location.  The SNMP management system is 
generally composed of agents (such as your PinPoint, a router, a UPS, a web server, a file server, or 
other computer equipment) and a Network Management Station (NMS) which monitors all the 
agents on a specific network.  Using the management information base (MIB), an NMS can include 
reporting, network topology mapping, tools to allow traffic monitoring and trend analysis, and 
device monitoring.
Authentication ensures SNMP messages coming from the agent, such as the PinPoint, have not 
been modified and the agent may not be queried by unauthorized users.   SNMPv3 uses a User-
Based Security Model (USM) to authenticate and, if desired or supported, message encryption.  
USM uses a user name and password specific to each device.
Management Information Base (MIB) 
The management information base (MIB) is a type of database used to compile the information 
from the various SNMP agents.  Reports from various agents, such as the PinPoint, are sent as data 
in form designed to be parsed by the NMS into its MIB.  The data is hierarchical with entries 
addressed through object identifiers. 
SNMP Traps 
SNMP traps are alerts that can be sent from the managed device to the Network Management Sta-
tion when an event happens. Your PinPoint is capable of sending the linkUp trap when the network 
connection becomes available.
PinPoint SNMP Configuration 
To configure your PinPoint to work as an SNMP agent, you can use either Wireless Ace, or a termi-
nal connection to configure the modem using AT commands. In Wireless Ace, the SNMP com-
mands are all on the Other menu option.
