Task SNMP - SNMP Get Bulk

Issues a 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 tables. The GETBULK operation performs a GETNEXT operation for the first 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 that the SNMP GETBULK command is not supported on devices using SNMPv1.
