How to Remove a VLAN

1. Assume the System Administrator role or become superuser.

   The System Administrator role includes the Network Management profile. To create the role and assign the role to a user, see Chapter 9, Using Role-Based Access Control (Tasks), in System Administration Guide: Security Services.

2. Determine which VLAN you want to remove.

   # dladm show-vlan

3. Unplumb the VLAN's IP interface.

   # ifconfig vlan-interface unplumb

   where vlan-interface is the IP interface that is configured over the VLAN.

   Note –

   You cannot remove a VLAN that is currently in use.

4. Remove the VLAN by performing one of the following steps:

   • To delete the VLAN temporarily, use the -t option as follows:

     # dladm delete-vlan -t vlan

   • To make the deletion persist, perform the following:

     1. Remove the VLAN.

        # dladm delete-vlan vlan

     2. Remove the /etc/hostname.vlan-interface file.
