  • Page 5: Configuring Vlan Termination

    Configuring VLAN termination Overview VLAN termination typically processes packets that include VLAN tags. A VLAN termination-enabled interface performs the following tasks when receiving a VLAN-tagged packet: Assigns the packet to an interface according to its VLAN tags. Removes the VLAN tags of the packet. Delivers the packet to Layer 3 forwarding or other processing pipelines.
  • Page 6 As shown in Figure 1, Host A and Host B are in dif ferent VLANs. The two host s can communicate with each other after you perform the following tasks: Specify 1.1.1.1/24 and 1.1.2.1/24 as the gateway IP addresses for Host A and Host B, respectively.

  • Page 7: Configuration Restrictions And Guidelines

    Configuration restrictions and guidelines When you configure VLAN termination, follow these restrictions and guidelines: • On a portal-enabled interface, log off all portal users before you change the VLAN termination type, for example, from Dot1q termination to QinQ termination. Any portal users who remain online after the change cannot be logged off or reauthenticated.

  • Page 8: Configuring Dot1Q Termination

    Configuring Dot1q termination Based on the range of outermost VLAN IDs in the VLAN-tagged packets that can be terminated by a subinterface, the following types of Dot1q termination are available: • Ambiguous Dot1q termination—Terminates VLAN-tagged packets whose outermost VLAN IDs are in the specified range. Any other VLAN-tagged packets are not allowed to pass through this subinterface.
