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 on VLANs and Layer 2, refer to Chapter 10, Layer 2, on page 47. Refer also to Chapter 18, VLAN Stacking, on page 367. Note: To monitor VLAN interfaces, use the Management Information Base for Network Management of TCP/ IP-based internets: MIB-II (RFC 1213). Monitoring VLAN interfaces via SNMP is supported only on E-Series. FTOS 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 on configuring different routing protocols, refer to the chapters on the specific protocol. A consideration for including VLANs in routing protocols is that the no shutdown command must be configured. (For routing traffic to flow, the VLAN must be enabled.) Note: An IP address cannot be assigned to the Default VLAN, which, by default, is VLAN 1. To assign another VLAN ID to the Default VLAN, use the default vlan-id vlan-id command. Assign an IP address to an interface with the following command the INTERFACE mode: Command Syntax ip address ip-address mask [secondary] Command Mode Purpose INTERFACE Configure an IP address and mask on the interface. • ip-address mask: enter an address in dotted-decimal format (A.B.C.D) and 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. The following example shows a sample configuration of a VLAN participating in an OSPF process. interface Vlan 10 ip address 1.1.1.2/24 tagged GigabitEthernet 2/2-13 tagged TenGigabitEthernet 5/0 ip ospf authentication-key force10 ip ospf cost 1 ip ospf dead-interval 60 ip ospf hello-interval 15 no shutdown !
