SNMP Configuration 

 

28-1 

Simple Network Management Protocol is a protocol used for exchanging management 
information between network devices. SNMP is a member of the TCP/IP protocol suite. Your 
HomeSafe supports SNMP agent functionality, which allows a manager station to manage and 
monitor the HomeSafe through the network.  The HomeSafe supports SNMP version one 
(SNMPv1) and version two c  (SNMPv2c). The next figure illustrates an SNMP management 
operation. SNMP is only available if TCP/IP is configured. 

 

An SNMP managed network consists of two main components: agents and a manager.  

An agent is a management software module that resides in a managed device (the HomeSafe). An 
agent translates the local management information from the managed device into a form 
compatible with SNMP. The manager is the console through which network administrators 
perform network management functions. It executes applications that control and monitor 
managed devices.  

The managed devices contain object variables/managed objects that define each piece of 
information to be collected about a device. Examples of variables include the number of packets 
received, node port status etc. A Management Information Base (MIB) is a collection of managed 
objects.  SNMP allows a manager and agents to communicate for the purpose of accessing these 
objects. 

SNMP itself is a simple request/response protocol based on the manager/agent model. The 
manager issues a request and the agent returns responses using the following protocol operations: 
•  Get - Allows the manager to retrieve an object variable from the agent.
