Appendix B 
SNMP Management 
Appendix B provides specific information for IPmux-16 management by SNMP 
(Simple Network Management Protocol). 
The SNMP management functions of IPmux-16 are provided by an internal SNMP 
agent. The SNMP management communication uses UDP (User Datagram 
Protocol), which is a connectionless-mode transport protocol, part of the IP 
(Internet Protocol) protocol suite. 
This appendix covers the information related to the SNMP environment.  
B.1 SNMP Environment 
SNMP Principles 
The SNMP management protocol is an asynchronous command-response polling 
protocol. All management traffic is initiated by the SNMP-based network-
management station, which addresses the managed entities in its management 
domain. Only the addressed managed entity answers the polling of the 
management station (except for trap messages). 
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.
