SNMP Get Bulk Action-Setting Properties

The SNMP get Bulk action issues an SNMP GETBULK message to an SNMP agent in order to inspect a group of variables in a single transaction. This action is particularly useful for retrieving large amount of data, particularly from large tables.

The GETBULK operation was implemented to allow Network Management Systems (NMS) to obtain multiple pieces of information from a managed device in a single request. The SNMP GETBULK operation performs a simple GETNEXT operation for the initial number of variable bindings in the request and performs a GETNEXT operation (continuous) for each of the remaining variable bindings in the request list.

NOTE: This action iss only compatible with SNMP v2c.

  1. From the Task Builder Available Actions pane, open the SNMP folder and double-click the SNMP Get Bulk action or drag it into the Steps pane.
