13 SNMP Manager
The Simple Network Management Protocol (SNMP) is an Internet standard protocol, widely
used for a network management station (NMS) to access and operate the devices (SNMP
agents) on a network, regardless of their vendors, physical characteristics and interconnect
technologies.
SNMP enables network administrators to read and set the variables on managed devices to
monitor their operating and health state, diagnose network problems, and collect statistics for
management purposes.
SIGNAMAX 065-7909HPOE industrial switch SNMP agents support three SNMP versions:
SNMPv1, SNMPv2c, and SNMPv3.
SNMPv1 uses Community Name authentication to control access to SNMP agents. SNMPv1
Community Name falls into “read only” passwords and “read and write” passwords.
A read Community Name enables reading data from an SNMP agent.
A read and write Community Name enables reading data and setting variables on an SNMP
agent.
SNMPv2c also uses Community Name authentication for SNMP agent access control. It is
compatible with SNMPv1, but supports more operation modes, data types, and error codes.
SNMPv3 uses a user-based security model (USM) to secure SNMP communication. You can
configure authentication and privacy mechanisms to authenticate access and encrypt SNMP
Note:
An NMS and an SNMP agent must use the same SNMP version to communicate with
each other.
SNMP management frame includes three network elements: SNMP Management Station,
