Management (SNMP)

The Simple Network Management Protocol (SNMP) is designed to allow for
remote management and monitoring of a variety of devices from a central
location. It is generally used to monitor conditions that may require attention.
The SNMP management system is composed of:
• One or more managers (administrative computers)
• SNMP-compliant devices (such as your AirLink gateway, a router, a UPS, a
web server, a file server, or other computer equipment)
• An agent (data collection software running on the SNMP-compliant devices)
• A Network Management System (NMS) that monitors all the agents on a
specific network.
The agent stores information about the device in a Management Information Base
(MIB). The manager can send messages to this database to configure and query
the status of the device. In addition, the agent running on the device can send
traps (unsolicited messages) to the manager on startup, on status change, or
when an error condition occurs.
AirLink gateways supports configuring SNMPv2 and SNMPv3 as SNMP agents.
Authentication ensures SNMP messages coming from the AirLink gateway have
not been modified and the device cannot 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.
A reboot is required after configuring SNMP.
