To set up the switch shown in Figure 12-4to establish a management VLAN on port 1, use the following process:

1.Use the Static VLAN Configuration screen to define a new VLAN named “Management VLAN” (or other suitable name) and its VLAN ID. In this example, the VLAN ID is set to 2.

An FDB ID is automatically assigned by the switch, so that the Management VLAN has its filtering database to make the VLAN secure. In this example, the FDB ID is 2 and no other VLAN is assigned to this FDB ID. This keeps the new VLAN from sharing its filtering database with other VLANs in the switch.

2.Use the Static VLAN Egress Configuration screen to associate the ports to particular VLANs. For details on defining a Static VLAN, refer to Section 7.3.1.

3.Use the Static VLAN Egress Configuration screen to select the type of Egress setting for each port. When a port is set as Tagged, a VLAN tag is inserted into each frame transmitted out the port to associate it with the VLAN specified at the top of the screen.

4.Use the VLAN Port Configuration screen to enter the VLAN ID, 2, of the new Management VLAN as the Port VLAN ID (PVID) to a port. In this example, it is port 1. Leave the Acceptable Frame Types setting in the default value, ADMIT ALL FRAMES.

NOTE: It is not necessary to configure a physical port for management on each switch. Only those switches that will have a management station attached to it need a physical port assigned to the Management VLAN.
