The notification information includes the following two types:
Trap ： Trap is the information that the managed device initiatively sends to the Network
management station without request.
Inform：Inform packet is sent to inform the management station and ask for the reply. The switch
will resend the inform request if it doesn’t get the response from the management station during
the Timeout interval, and it will terminate resending the inform request if the resending times reach
the specified Retry times. The Inform type, employed on SNMPv2c and SNMPv3, has a higher
security than the Trap type.
