FCD-E1LC Ver. 1.0 SNMP Environment B-1
Appendix B
SNMP Management
This appendix provides specific information related to the management of
FCD-E1LC units by means of the Simple Network Management Protocol (SNMP).
Some of the information presented in this Appendix is also applicable for
management using Telnet.
The information presented in this Appendix is organized as follows:
• Description of SNMP environment –
Section
B.1
• SNMP traps supported by FCD-E1LC –
Section B.2
• Information on the handling of inband and out-of-band SNMP and Telnet
management traffic by the FCD-E1LC internal SNMP agent –
Section B.3.
B.1 SNMP Environment
General
The SNMP management functions of the FCD-E1LC are provided by an internal
SNMP agent, which can use inband and out-of-band communication (see
Section B.3
).
The SNMP management communication uses the User Datagram Protocol (UDP),
which is a connectionless-mode transport protocol, part of the suite of protocols
of the Internet Protocol (IP).
Telnet management uses the TCP protocol over IP for management
communication. After a Telnet session is started, the management interface is
similar to that used for the supervision terminal.
SNMP Principles
The SNMP management protocol is an asynchronous command/response polling
protocol: the SNMP-based network management station, which addresses the
managed entities in its management domain, initiates all the management traffic.
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 the interpretation and handling of the management station
requests to the managed entity, and the generation of properly-formatted
responses to the management station.
