VLAN interface configuration
NOTE:
For more information about VLANs, see the chapter “VLAN configuration.”
For hosts of different VLANs to communicate, you must use a router or Layer 3 switch to perform layer 3
forwarding. To achieve this, VLAN interfaces are used.
VLAN interfaces are virtual interfaces used for Layer 3 communication between different VLANs. They do
not exist as physical entities on devices. For each VLAN, you can create one VLAN interface. You can
assign the VLAN interface an IP address and specify it as the gateway of the VLAN to forward the traffic
destined for an IP subnet different from that of the VLAN.
Configuring VLAN interfaces
Configuration task list
Perform the tasks in Table 55 to configure a VLAN interface:

see the chapter “VLAN configuration.”
Modifying a VLAN interface
