VLAN Interfaces

VLANs are logical interfaces and are, by default, in Layer 2 mode. Physical interfaces and port channels can be members of VLANs.

For more information about VLANs and Layer 2, refer to Layer 2 and Virtual LANs (VLANs).
  • NOTE: To monitor VLAN interfaces, use Management Information Base for Network Management of TCP/IP-based internets: MIB-II (RFC 1213).
  • NOTE: You cannot simultaneously use egress rate shaping and ingress rate policing on the same VLAN.

The Dell Networking OS supports Inter-VLAN routing (Layer 3 routing in VLANs). You can add IP addresses to VLANs and use them in routing protocols in the same manner that physical interfaces are used. For more information about configuring different routing protocols, refer to the chapters on the specific protocol.

A consideration for including VLANs in routing protocols is that you must configure the no shutdown command. (For routing traffic to flow, you must enable the VLAN.)

  • NOTE: You cannot assign an IP address to the default VLAN, which is VLAN 1 (by default). To assign another VLAN ID to the default VLAN, use the default vlan-id vlan-id command.

To assign an IP address to an interface, use the following command.

Configure an IP address and mask on the interface. INTERFACE mode ip address ip-address mask [secondary]

  • ip-address mask : enter an address in dotted-decimal format (A.B.C.D). The mask must be in slash format (/24).

  • secondary: the IP address is the interface’s backup IP address. You can configure up to eight secondary IP addresses.

Example of a Configuration for a VLAN Participating in an OSPF Process 

interface Vlan 10
                                 ip address 1.1.1.2/24

                                 tagged TenGigabitEthernet 5/0
                                 ip ospf authentication-key Dell force10
                                 ip ospf cost 1
                                 ip ospf dead-interval 60
                                 ip ospf hello-interval 15
                                 no shutdown
