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 (VLAN). Note: To monitor VLAN interfaces, use the 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. 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 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, the VLAN must be enabled.) Note: You cannot assign an IP address 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 in the INTERFACE mode: Command Syntax ip address ip-address mask [secondary] Command Mode INTERFACE Purpose 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. Figure 13-9 shows a sample configuration of a VLAN participating in an OSPF process. Figure 13-9.
