Configuring the Control VLAN

Control and member VLANS are configured normally for Layer 2. Their status as control or member is determined at the FRRP group commands.

For more information about configuring VLANS in Layer 2 mode, refer to Layer 2.
Be sure to follow these guidelines:
  • All VLANS must be in Layer 2 mode.
  • You can only add ring nodes to the VLAN.
  • A control VLAN can belong to one FRRP group only.
  • Tag control VLAN ports.
  • All ports on the ring must use the same VLAN ID for the control VLAN.
  • You cannot configure a VLAN as both a control VLAN and member VLAN on the same ring.
  • Only two interfaces can be members of a control VLAN (the Master Primary and Secondary ports).
  • Member VLANs across multiple rings are not supported in Master nodes.

To create the control VLAN for this FRRP group, use the following commands on the switch that is to act as the Master node.

  1. Create a VLAN with this ID number.
    CONFIGURATION mode.
    interface vlan vlan-id
    VLAN ID: from 1 to 4094.
  2. Tag the specified interface or range of interfaces to this VLAN.
    CONFIG-INT-VLAN mode.
    tagged interface {range}
    Interface:
    • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport] information.
    • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
  3. Assign the Primary and Secondary ports and the control VLAN for the ports on the ring.
    CONFIG-FRRP mode.
    interface primary interface secondary interface control-vlan vlan id
    Interface:
    • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport] information.
    • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
  4. Configure the Master node.
    CONFIG-FRRP mode.
    mode master
  5. Identify the Member VLANs for this FRRP group.
    CONFIG-FRRP mode.
    member-vlan vlan-id {range}
    VLAN-ID, Range: VLAN IDs for the ring’s member VLANS.
  6. Enable FRRP.
    CONFIG-FRRP mode.
    no disable
