Assigning an IP Address to a VLAN
VLANs are a Layer 2 feature. For two physical interfaces on different VLANs to
communicate, assign an IP address to the VLANs to route traffic between the
two interfaces.
The shutdown command in INTERFACE mode for a VLAN does not affect
Layer 2 traffic on the VLAN.
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 from the configuration
mode.
