Introduction
Simple Network Management Protocol (SNMP) is used in network management systems to
monitor network-attached devices for conditions that warrant administrative attention. SNMP is a
component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF).
It consists of a set of standards for network management, including an application layer protocol,
a database schema, and a set of data objects.
SNMP exposes management data in the form of variables on the managed systems, which
describe the system configuration. These variables can then be queried (and sometimes set) by
managing applications.
Support below MIBs:
» RFC 1157 A Simple Network Management Protocol
» RFC 1213 MIB-II
» RFC 1493 Bridge MIB
» RFC 1643 Ethernet Interface MIB
» RFC 1757 RMON Group 1,2,3,9
SNMP community act like passwords and are used to define the security parameters of SNMP
clients in an SNMP v1 and SNMP v2c environments. The default SNMP community is “public”
for both SNMP v1 and SNMP v2c before SNMP v3 is enabled. Once SNMP v3 is enabled, the
communities of SNMP v1 and v2c have to be unique and cannot be shared.
Network ID of Trusted Host:
The IP address is a combination of the Network ID and the Host ID.
Network ID = (Host IP & Mask).
User need only input the network ID and leave the host ID to 0. If user has input the host ID, such
as 192.168.1.102, the system will reset the host ID, such as 192.168.1.0
Note: Allow user to configure the community string and rights only.
