CHAPTER 10: VLAN VLAN

10.3Configuring Port VLANs with EnerVista Secure Web Management software

10.3.1 Description

Port VLANs are rarely used, and are not recommended, in networks which use VLANs across multiple switches. Port VLANs are used when VLANs are setup up on a single switch and connectivity between the systems on different VLANs is needed; however, the broadcasts and multicasts are isolated to the specific VLAN.

Either port VLANs or Tag VLAN can be active at any given time on a switch. Only the default

VLAN (VLAN ID = 1) is active as a Tag VLAN as well as a port VLAN.

General steps for using port VLANs are

1.Plan your VLAN strategy and create a map of the logical topology that will result from configuring VLANs. Include consideration for the interaction between VLANs.

2.Configure at least one VLAN in addition to the default VLAN.

3.Assign the desired ports to the VLANs

4.Decide on trunking strategy – how will the VLAN information be propagated from one switch to another and also what VLAN information will be propagated across.

5.Layer 3 consideration – check to see if the routing between the VLANs is “working” by pinging stations on different VLANs

You can rename the default VLAN, but you cannot change its VID =1 or delete it from the switch.

Any ports not specifically assigned to another VLAN will remain assigned to the DEFAULT-

VLAN (VID=1).

Changing the number of VLANs supported on the switch requires the changes to be saved for future use. To eliminate the changes, reboot the switch without saving the changes.

For VLAN configuration use Configuration > VLAN menu items as shown below. The Port

VLANs are active by default.
