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.
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.
In the Agent IP address field located in the General tab properties, enter the IP address or host name of the agent to communicate with.
In the parameter labeled Return variable for the first [ ] variable bindings enter the number of variables for which a simple GETNEXT operation will be performed.
In the parameter labeled Max number of variables to be returned for the rest of the variable bindings enter the amount of variables for which a GETNEXT operations will be performed.
In the Community box, enter the SNMP community.
In the Create and populate dataset box, enter the name of a dataset to be created and populated with the results of the request.
Select the Advanced tab.
If you want to use a different TCP/IP port than the default 161, enter it in the Remote port box.
If you want to specify a time out, enter the value and select the increment in the Time out after boxes. If the action is not complete before this time elapses, the step fails. The default is 30 seconds.
Select the Data Bindings tab. This is used to enter variable bindings.
To add a variable name, click the Add button. This will present a dialog titled Define variable binding in which the proper variable can be entered. Added variable bindings are displayed in the Variable name parameter. Variables can be moved up or down the list with the use of “drag and drop.”
To edit or delete an existing variable, highlight the desired variable and click Edit or Delete.
