IPM Profile

The Intelligent Power Monitoring (IPM) 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, where 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.

By default, IPM is disabled. When disabled, the static power management method limits the operation and performance of an AP based on the worst case power usage model where the power profiles are hard-coded for each AP. In order to manage this prioritization, you can define a set of power reduction steps and associate them with a priority. IPM applies a sequence of power reduction steps as defined by the priority definition until the AP is functioning within the power budget. This happens dynamically as IPM constantly monitors the AP power consumption and reacts to over-consumption by applying the next power reduction step in the priority list if the AP exceeds the power threshold.

Creating an IPM Profile

To create an IPM server profile, complete the following steps:

  1. In the HPE Aruba Networking Central landing page, click the configurationicon.
    The Profiles tab is displayed.

  2. In the left navigation menu, select one of the following options:

    • Library—This is the default selection. If you create profiles in the Library, then you must assign scope and device functions to the profiles. For more information, see Assigning Scope to an IPM Profile.

    • Global—If you create profiles at the Global level, then the profiles have Global scope assigned by default.

    • Site Collections—If you create profiles at the Site Collections level, then the profiles have site collection scope assigned by default.

    • Sites—If you create profiles at the Site level, then the profiles have site scope assigned by default.

    • Devices—If you create profiles at the Device level, then the profiles have device scope assigned by default.

    • Device Groups—If you create profiles at the Device Group level, then the profiles have device group scope assigned by default.

    Note:

    • To create profiles at the Global level, select the device type from the Device Function drop-down list before step 4.
    • To create profiles at the Site Collections, Sites, Devices, and Device Group level, complete the following steps before step 4:
      1. Select Site Collection, Site, Device, or Device Group in the left navigation menu.
      2. Select a Site Collection, Site, Device, or Device Group from the list view depending on the level where you are creating the profile.
      3. Select the device type from the Device Function drop-down list.

  3. On the System card, click the second radio button, and then click IPM.

    Alternatively, you can complete the following steps:

    1. On the System card, click Manage.

    2. On the IPM card, click Manage.

    The IPM page is displayed.

  4. Click Create Profile.
    The Create Profile side panel is displayed.

  5. Configure the following IPM profile parameters:

    • Create as a local profile—Select this option if you want to configure this profile as local.

      Note:

      The Create as a local profile option is available at the Global, Site Collections, Sites, Devices, and Device Groups levels; it is not available at the Library level.

    • Name—Enter the name of the IPM profile.

    • Description—Enter the description for the IPM profile.

    • IPM Activation— Select the check box to enable IPM.

  6. Click the Add icon on the IPM Step table.

    The Create IPM Step pane is displayed.

  7. Configure the following IPM Step parameters:

    • Step—Select the IPM reduction step from the drop-down list.

    • Priority—Enter a value from 1 to 16 to define IPM priority.

  8. Click Add to add the IPM.

  9. Click Create.

    The newly created IPM profile is displayed in the IPM list.

  10. To edit a profile, complete the following steps:

    1. Click anywhere on the row of the profile in the list view.

      The profile edit view is displayed in the side panel.

    2. Edit the required parameters.

    3. Click Update.

  11. To delete an IPM server profile, hover on the profile name, and click the delete icon.

  12. To search for a profile, type the profile name in the search bar.
    The search bar displays dynamic results as soon as you start typing.

The following image displays the Create Profile side panel of an IPM profile.

Assigning Scope to an IPM Profile

For profiles created under Library, you must assign a scope and device function to be able to use its features and functionality.

To assign scope to a profile, complete the following steps:

  1. In the HPE Aruba Networking Central landing page, click the configurationicon.
    The Profiles tab is displayed.

  2. Ensure that the default option Library is selected in the left navigation menu.

  3. On the System card, click the second radio button, and then click IPM.

    Alternatively, you can complete the following steps:

    1. On the System card, click Manage.

    2. On the IPM card, click Manage.

    The IPM page is displayed.

  4. Hover on the profile to which you want to assign a scope and click the ellipsis icon.

  5. Select Assign.

    The Assign Profile side panel is displayed.

  6. Select the device types from Device Function list.

  7. To add a scope, click the Addicon on the Scopes table.

  8. Select a scope from the following Scope Level options in the drop-down list.

    • Global—Selecting this option assigns the scope at the Global level.

    • Site Collections—Select the site collections from the Assign to Scope drop-down list.

    • Sites—Select the sites from the Assign to Scope drop-down list.

    • Devices—Select the devices from the Assign to Scope drop-down list.

    • Device Groups—Select the device groups from the Assign to Scope drop-down list .

  9. Click Add.

    The Scopes table displays the newly added scopes.

  10. Click Assign.

    The IPM list displays the device functions and number of scopes assigned to the profile.

  11. To unassign a scope from a profile, complete the following steps:

    1. Hover on the profile name and click the ellipsis icon.

    2. Select Unassign. The Unassign pop-up window is displayed.

    3. Select the required scope and click Unassign.

  12. To customize the IPM profile list, click the Customize Columns icon . For more information, see Customizing List.
