MAX-207HW2R User’s Guide

• GetNext - Allows the manager to retrieve the next object variable from a table 

or list within an agent. In SNMPv1, when a manager wants to retrieve all 

elements of a table from an agent, it initiates a Get operation, followed by a 

series of GetNext operations. 

• Set - Allows the manager to set values for object variables within an agent. 
• Trap - Used by the agent to inform the manager of some events.

The MAX-207HW2R sends traps to the SNMP manager when any of the following 
events occurs:
