SNMP Device Management
Introduction The STB NIP 2212 contains a Simple Network Management Protocol (SNMP)
Version 1.0 agent that is capable of supporting up to three concurrent SNMP
connections.
User Datagram
Protocol (UDP)
On the STB NIP 2212, SNMP services are delivered via the UDP/IP stack. UDP is
the transport protocol used by the SNMP application in its communications with the
STB NIP 2212.
SNMP Agents
and Managers
The SNMP network management model uses the following terminology and
definitions:
manager—the client application program running on the master
agent—the server application running on a network device, in this case, the
STB NIP 2212
The SNMP manager initiates communications with the agent. An SNMP manager
can query, read data from and write data to other host devices. An SNMP manager
uses UDP to establish communications with an agent device via an "open" Ethernet
interface.
When the STB NIP 2212 is successfully configured with SNMP, the STB NIP 2212
agent and the SNMP manager devices can recognize one another on the network.
The SNMP manager can then transmit data to and retrieve data from the
STB NIP 2212.
Network
Management
Application
SNMP software allows an SNMP manager (remote PC) to monitor and control the
STB NIP 2212. Specifically, SNMP services are used to monitor and manage:
performance
faults
configuration
security
Note: BootP and the DHCP applications also use UDP as their transport layer
when communicating with the STB NIP 2212.
