The VLANs page (**Network** **Analysis** tab > **Performance** tab > **History** section > **VLANs**) is a network-wide or device-group-specific view of the collection of distinct VLANs in the discovered network. The table shows the total of active VLAN networks in the L3-switched environment. For more information, see *[Inspecting Ethernet Switches and VLANs](https://infoblox-docs.atlassian.net/wiki/spaces/netmri760/pages/357566174)*.
