    Understanding VLAN Profiles

    A virtual LAN (VLAN) is a Layer 2 broadcast domain that can span multiple wired or wireless LAN segments. Each VLAN is a separate logical network, grouping hosts with common requirements, regardless of their physical location.

    VLAN profiles in Network Director enable multiple VLAN configuration from a single profile. Each VLAN profile is specific to a device family: EX Switching, Wireless, Campus Switching ELS, or Data Center Switching Non-ELS. In addition, the VLANs are created for different purposes at different levels, as shown in Figure 1.

    After a VLAN profile is created, you assign it to either wireless ports, switches, controllers, custom groups, port groups with wireless ports, or access points that are managed by controllers or clusters. You can also assign VLAN profiles to controller-managed access points and cluster-managed access points for local switching on the access points.

    For EX Series Switches and Campus Switching ELS, apart from the basic settings, you can specify:

    • MAC parameters
    • Switching and routing parameters
    • L2 and L3 Filters
    • VLAN security DHCP, ARP inspection, and MAC movement.

    For controllers, apart from the basic settings, you can specify:

    • Filter details
    • Routing
    • DHCP enabled
    • IGMP settings
    • Spanning tree protocol settings

    For data center switching devices, apart from the basic settings, you can specify:

    • MAC parameters
    • Switching and routing parameters
    • Filters
    • VLAN security settings
    • Fibre Channel over Ethernet (FCoE) Initialization Protocol (FIP) settings

    Tip: Single VLAN IDs can be configured for all products and circumstances. VLAN lists or VLAN ranges of IDs are available for some products, depending on the technology used for implementation. For example, EX Switching does not support a VLAN list. Campus Switching ELS supports a VLAN ID range only as part of a VLAN ID list. You will only see the available configurations for the selected device family.
