Configuring Intelligent Power Monitoring for Microbranch APs
The Intelligent Power Monitoring (IPM Intelligent Power Monitoring. IPM is a feature supported on certain APs that actively measures the power utilization of an AP and dynamically adapts to the power resources.) feature actively measures the power utilization of an AP and dynamically adapts to the power resources. IPM allows you to define the features that must be disabled to save power, allowing the APs to operate at a lower power consumption.
IPM dynamically limits the power requirement of an AP as per the available power resources. IPM applies a sequence of power reduction steps in a prioritized order until the AP functions within the power budget. This happens dynamically as IPM constantly monitors the AP power consumption and applies the next power reduction step in the priority list, if the AP exceeds the power threshold. To manage this prioritization, you can create IPM policies to define a set of power reduction steps and associate each step with a priority. The IPM policies, when applied to the AP, are based on IPM priorities. The IPM policy can be configured to disable or reduce certain features in a specific sequence, to reduce the AP power consumption below the power budget. IPM priority settings are defined by integer values, where the lower values have the highest priority and are implemented first.
To configure IPM for Microbranch APs:
Points to remember
- By default, IPM is disabled.
- When enabled, IPM enables all AP functionalities initially. IPM then proceeds to shut down or restrict the functionalities if the power usage of the AP goes beyond the power budget of the AP.
- Although AOS 10 allows flexible configuration of the radio band Band refers to a specified range of frequencies of electromagnetic radiation. on some APs, the radio index always remains fixed.
- Some reduction steps are available only for select AP platforms. For example, radio_2_disable step is applicable to any AP that has three radios such as AP-555 and AP-655, irrespective of the frequency band under which they operate.
- To reduce the CPU Central Processing Unit. A CPU is an electronic circuitry in a computer for processing instructions. power gradually, the smallest reduction is allocated a higher priority value so that the minimum reduction step is implemented first. For example, the cpu_throttle_50 parameter should have a higher priority value than the cpu_throttle_25 parameter, so that IPM gradually reduces the CPU throttle or power usage based on the priority list.
