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.
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 conguring dierent routing
protocols, refer to the chapters on the specic protocol.
A consideration for including VLANs in routing protocols is that you must congure the no shutdown command. (For routing
trac to ow, 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.
• Congure 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 congure up to eight secondary IP addresses.

Loopback Interfaces
A Loopback interface is a virtual interface in which the software emulates an interface. Packets routed to it are processed locally.
Because this interface is not a physical interface, you can congure routing protocols on this interface to provide protocol stability.
You can place Loopback interfaces in default Layer 3 mode.
To congure, view, or delete a Loopback interface, use the following commands.
• Enter a number as the Loopback interface.
CONFIGURATION mode
interface loopback number
The range is from 0 to 16383.
