SNMP Management
C.1 Scope
This appendix provides the specific information required for the management of
the MX-2100 equipment by means of the Simple Network Management Protocol
(SNMP).
C.2 SNMP Environment
General
MX-2100 SNMP management functions are provided by an internal SNMP agent,
located in the KCL.2 module.
SNMP management uses the User Datagram Protocol (UDP), which is a
connections-mode transport protocol, part of the Internet Protocol (IP) suite of
protocols. This section covers the information related to the SNMP environment.
SNMP Principles
The SNMP management protocol is an asynchronous command/response polling
protocol: all the management traffic is initiated by the SNMP-based network
management station (except for trap messages), which addresses the managed
entities in its management domain. Only the addressed managed entity answers
the polling of the management station.
The managed entities include a function called an SNMP agent, which is
responsible for interpretation and handling of the management station requests to
the managed entity, and the generation of properly-formatted responses to the
management station.
SNMP Operations
The SNMP protocol includes four types of operations:
•
getRequest - Command for retrieving specific management information from
the managed entity. The managed entity responds with a getResponse
message.
•
getNextRequest - Command for retrieving sequentially specific management
information from the managed entity. The managed entity responds with a
getResponse message.
