MGMD Global Profile

The MGMD Global profile defines how multicast traffic is managed across the fabric. It controls IGMP and MLD snooping behavior, ensuring efficient replication, filtering, and synchronization of multicast streams.

Note:

This profile is supported only on Aggregation Switch and Core Switch device functions.

Creating an MGMD Global Profile

To create an MGMD Global 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 MGMD Global 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 VLANs & Networks card, click MGMD Global.
    Alternatively, you can complete the following steps:

    1. On the VLANs & Networks card, click Manage.

    2. On the MGMD Global card, click Manage.

    The MGMD Global list view is displayed.

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

  5. Configure the MGMD Global profile parameters:

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

      Note:

      The Create as a local profile checkbox 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 MGMD Global profile.

    • Description—Enter the description for the MGMD Global profile.

    • Querier offload— Select the checkbox to enable the IGMP/MLD querier (mgmd) offload feature. When the querier offload is enabled, during a VSX software upgrade or a VSX querier node reboot, the querier responsibility is offloaded to the VSX peer that is up and running. This is enabled by default.

  6. Under IGMP and MLD, configure the following parameters:

    • Filter unknown multicast—Select the checkbox to avoid initial flooding of unknown multicast traffic on IGMP or MLD snooping enabled VLANs. When enabled, multicast packets for groups without registered members are blocked instead of being flooded across the VLAN. This option is enabled by default.

    • Drop unknown multicast—Select one of the following options from the drop‑down list to configure how unknown multicast traffic is dropped:

      • Across All VLANs—Applies globally

      • Per VLAN—Applies individually per VLAN

  7. Click Create.

  8. To delete an MGMD Global profile, hover over the profile name, and click the delete icon.

  9. 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.
