Media Flow Controller Overview : Management Interfaces : SNMP Interface to Network Management System

SNMP Interface to Network Management System
The Simple Network Management Protocol (SNMP) is used by network management systems (NMS) to communicate with properly configured network elements. Media Flow Controller can be integrated with 3rd party network management systems via its built-in SNMP agent. The Media Flow Controller SNMP agent provides the following functions:
SNMP Messages (TRAPs, GETs, and SETs)
SNMP messages may be initiated by either the network management system (NMS) or by the Media Flow Controller. An SNMP TRAP is a message initiated by a Media Flow Controller and sent to the NMS; for example, a message that one of its redundant power supplies failed. An SNMP GET is a message initiated by the NMS when it wants to retrieve some data from a network element; for example, the network management system might query a Media Flow Controller for the utilization on a WAN link every 5 minutes. It could then create graphs from that data, or warn the administrator when the link was overutilized. An SNMP SET is a message initiated by the NMS when it wants to change data on a network element (i.e. alter a static route); in Release 2.0.2 Media Flow Controller does not support SNMP SET.
The SNMP MIB
The SNMP MIB, or Management Information Base, is a collection of variables shared between the NMS and the Media Flow Controller. The MIB is extensible, which means that hardware and software manufacturers can add new variables to the MIB. These new MIB definitions must be added both to the Media Flow Controller and the network management system. See Appendix C, “Media Flow Controller MIB Definitions for details.
SNMP Community Strings
The most basic form of SNMP security is the Community String. SNMP Community Strings are like passwords for network elements. Most often, there is one community string which is used for read-only (ro) access to a Media Flow Controller. The default value for this community string is public. Using this community string like a password, the NMS can retrieve data from Media Flow Controllers. Less often, there is also a read-write (rw) community string. The default value for this is private. Using this community string, the NMS can change MIB variables on a network element. In Release 2.0.2 only SNMP ro (Read-Only) is supported.
