Interfaces

www.dell.com | support.dell.com

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

. See also 

Chapter 18, VLAN Stacking, on page 367

. 

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 

 command must be 

configured. (For routing traffic to flow, the VLAN must be enabled.) 

Assign an IP address to an interface with the following command the INTERFACE mode: 

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.

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 

 

 command.

INTERFACE

Configure an IP address and mask on the interface.

•

 enter an address in 

dotted-decimal format (A.B.C.D) and the mask 
must be in slash format (/24).

•

 the IP address is the interface’s 

backup IP address. You can configure up to eight 
secondary IP addresses.
