5.10.7 Management (SNMP)
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 RLXIC-EV, 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
RLXIC-EV, 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.
The RLXIC-EV can be configured as an SNMP agent and supports SNMPv2c
and SNMPv3.
Field AT Command Description
SNMP Port *SNMPPORT This controls which port the SNMP Agent listens on.
 SNMP is disabled
 65535
SNMP Security
Level
*SNMPSECLVL
Selects the security level requirements for SNMP
communications.
 n=0: No security required. SNMPv2c and SNMPv3
communications are allowed.
 n=1: Authentication equivalent to "authNoPriv"
setting in SNMPv3. SNMPv3 is required to do
authentication, SNMPv2c transmissions will be
silently discarded.
 n=2: Authentication and encryption, equivalent to
"authPriv"' setting in SNMPv3. SNMPv3 is required
to do authentication and encryption, SNMPv2c and
SNMPv3 authNoPriv transmissions will be silently
discarded. Messages are both authenticated and
encrypted to prevent a hacker from viewing its
contents.
