Re: About Snmp trap OID mean

Hi Castle,

OID is object identifier in the MIB hierarchy. This is something like path to variables in our device - i.e. temperature, limits, alarms, etc.

"Values" OIDs' for Tx5xx (T7511, T3511, T4511, T2514) are:
Temperature    .1.3.6.1.4.1.22626.1.2.3.1.0
Humidity          .1.3.6.1.4.1.22626.1.2.3.2.0
Comp. quant.   .1.3.6.1.4.1.22626.1.2.3.3.0
Pressure          .1.3.6.1.4.1.22626.1.2.3.4.0

Every Tx5xx "alarm trap" has two items (String message + xxxx alarm description).

Trap OID's (Tx5xx):
String message (Alarm Temperature High, Alarm Humidity High, Clearing Pressure Alarm, etc.)   .1.3.6.1.4.1.22626.1.2.5.1.0

xxxx alarm description:
Temperature alarm description (0 = OK, 2 = low, 1 = high)                                                       .1.3.6.1.4.1.22626.1.2.5.2.0
Humidity alarm description (0 = OK, 2 = low, 1 = high)                                                             .1.3.6.1.4.1.22626.1.2.5.3.0
CV alarm description (0 = OK, 2 = low, 1 = high)                                                                     .1.3.6.1.4.1.22626.1.2.5.4.0
Pressure alarm description (0 = OK, 2 = low, 1 = high)                                                             .1.3.6.1.4.1.22626.1.2.5.5.0

All OIDs' you can learn from our MIB tables. For more information about SNMP you can read on http://en.wikipedia.org/wiki/SNMP .
