InvalidResponseHandling

Remarks

This tag can only be used for table parameters.

SLSNMPManager has a safeguard mechanism to prevent endless polling in case polling a table results in an infinite loop. When SLSNMPManager detects an infinite loop while polling a table, the response will be rejected by default. To override this default behavior, InfiniteLoop can be configured. If you want SLSNMPManager to accept a response in case of an infinite loop, specify <InfiniteLoop>success</InfiniteLoop>.

Note

Regardless of the InvalidResponseHandling setting, when an infinite loop is detected, a message will be logged in the element's log file (type ERROR, level 0):

  • If the response is accepted, the following message is logged: Detected an infinite loop when polling parameter with ID=<tableId>, InvalidResponseHandling was set to accept the data.
  • If the response is rejected, the following message is logged: Detected an infinite loop when polling parameter with ID=<tableId>, rejected the polled data.
