Planning a VLAN Configuration

Planning a VLAN configuration involves the following steps:

1. Examine the LAN topology and determine where subdivision into VLANs is appropriate.

   For a basic example of such a topology, refer to Figure 3–1.

2. Create a numbering scheme for the VLAN IDs, and assign a VLAN ID to each VLAN.

   Note -  If VLAN numbering scheme already exists on the network, you must create VLAN IDs within the existing VLAN numbering scheme.

3. On each system, determine which interfaces are the components of a particular VLAN.

   1. Determine which links are configured on the system by using the dladm show-link command.

   2. Determine which VLAN ID will be associated with each datalink on the system.

   3. Create the VLAN.

4. Check the connections of the datalinks to the switches of the network.

   Note the VLAN ID of each datalink and the switch port where each interface is connected.

5. Configure each port on the switch with the same VLAN ID as the interface to which it is connected.

   Refer to the switch manufacturer's documentation for configuration instructions.
