Through device groups, switch port management enables you to monitor and analyze the complement of Ethernet trunks and switch ports in their network. Switch port information gathering, or polling, is the key tool for doing this. Device groups can specify unique switch port management polling settings. Polling settings that are located under the **Settings** icon > **Setup** > **Collection** **and** **Groups** > **Groups** tab take precedence over the global settings defined in the **Settings** icon > **Setup** > **Collection and Groups** > **Global** > **Switch Port Management**.

To poll a device group or create custom settings for polling, perform the following:

1. In the Device Group Selector, right-click the **Switching** device group and select **Edit** ** Device ** **Group**. The Edit Device Group dialog opens. The **Switching** device group is an extended device group that provides several features designed for Ethernet switching devices management.
2. Open the **Switch** **port** ** data** ** Collection** dropdown. Select from the following options:

> Macro (legacy-content)

3. Click **Save** **&** **Close** or **Save** **&** **New**.

The settings you define here apply only to the chosen device group.
