Non-alarm trap. The non-alarm trap including the maintain, test, topology and datachange trap, options as: maintain(2), standard(12), topo(13), test(14) and datachange(15). The format of a non-alarm trap is as follows: | PDU Type | RequestID | ErrorStatus | ErrorIndex | Variable-bindings | The format of Variable-bindings in non-alarm trap is as follows: | sysUpTime | snmpTrapOID | TrapSN | InfoLevel | Specific-trap | Agent-addr | TrapID | Para-0 | Para-1 | Paras... |
