If GETBULK returns less (no) variable bindings than you expect it to return then check
- the maxRepetitions parameter of the GETBULK request PDU
- the maxSizeRequestPDU parameter of the Target
- whether the agent has local limits (i.e., memory) that do not allow to return a bigger GETBULK response PDU. In that case, the GETBULK response will contain less variable bindings than .
- whether the expected response PDU exceeds the MTU size of the used UDP network. In that case, the request will time out because UDP packets are usually not reassambled.
