The Type / Units column identifies the data type or units of measure. This is useful in interpreting alarm settings and the nature of reports that can be generated. If the type is “Enumerated text”, the enumerated values that the attribute can have are listed with the description of the attribute. Note that some attributes have enumerated values that can only occur under software control.
For units of “Duration” or “Bytes”, the values displayed in the NMS are scaled to a suitable unit. For example, durations scale to seconds, minutes, hours, or days; bytes scale to Kilobytes, Megabytes, or Gigabytes.
The scale of bytes displayed by the NMS uses the “natural” measure of powers of 10. For example 3 MBytes = 3 x 106 = 3,000,000 bytes. This is not the same as powers of 2 normally used for computing, where 3 MBytes =
3 x 220 = 3,145,728 bytes.The three columns on the right indicate if the attribute can be reportedin chart form (C) and text form (T), and the alarm attribute code (Alarm) used to monitor the attribute where available. In the PDF
edition of this document, the alarm code is a hyperlink to the entry in Chapter 7, “Troubleshooting Alarms”.
