Enabling the MUX VLAN Function on a Port

Enabling the MUX VLAN Function on a Port


After the MUX VLAN function is enabled on a port, the principal VLAN and subordinate VLAN can communicate with each other; ports in a group VLAN can communicate with each other; ports in a separate VLAN cannot communicate with each other.

Pre-configuration Tasks

Before enabling the MUX VLAN function on a port, complete the following task:
  • Adding the port to a principal or subordinate VLAN as an access, hybrid, or trunk interface


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run port link-type { hybrid | access | trunk }

    The port link-type is set.

  4. Run port mux-vlan enable vlan { vlan-id1 [ to vlan-id2 ] } &<1-10>

    The MUX VLAN function is enabled.

    After the MUX VLAN function is enabled on an interface, VLAN stacking and VLAN mapping cannot be configured on the interface.

    • Access interfaces can be added to only one MUX VLAN group. Trunk and hybrid interfaces can be added to multiple MUX VLAN groups. An interface can be added to a maximum of 32 MUX VLAN groups.

    • The interface enabled with the MUX VLAN function cannot be added to other VLANs of the MUX VLAN group.
    • Disabling MAC address learning or limiting the number of learned MAC addresses on an interface affects the MUX VLAN function on the interface.

    • The MUX VLAN and port security functions cannot be enabled on the same interface.

    • In a cascading scenario, the MUX VLAN cannot be enabled between interfaces connecting access and aggregation devices.

  5. Run commit

    The configuration is committed.
