Core issue

These are the requirements for the VLAN interface to be up/up:

  • The VLAN must exist in the VLAN database and must be active.
  • At least one port must be assigned to the VLAN.
  • The VLAN must contain an active device.

Resolution

For information on how to configure layer 3 interfaces on a Cisco Catalyst 4500 series switch, refer to Configuring Layer 3 Interfaces.
