The MIB access used in subsequent explanations is described below.

- MIB access classification

  Access name | Description
  --- | ---
  R/O | Access to the MIB is read-only

The relational formula is as follows: pethMainPseUsageThreshold = ROUND (100 * (pethMainPsePower - Guard band value) / pethMainPsePower) The minimum value that can be specified is calculated using the following formula. Minimum = ROUND ((pethMainPsePower - 30) / pethMainPsePower) Note: ROUND indicates rounding off to the nearest whole number. If the calculation result is 100, the value of this MIB will be regarded as 99.
