CHAPTER 10: VLAN VLAN

10.2 Configuring Port VLANs through the Command Line Interface

10.2.1 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 system on different VLANs is needed however the broadcasts and multicasts are isolated to the specific VLAN.

GE recommends using the set-port command for setting the port based VLAN as well.

The port-based VLAN feature supports a maximum of 1 VLAN per port. Any pre-existing

VLAN tags on traffic coming into the switch on a port-based VLAN port will be removed.

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

Changing the number of VLANs supported on the switch requires the SAVE command to save the new VLAN information

10.2.2 Commands

The following commands are used for VLANs. To define the VLAN type:

set vlan type=<porttagnone>

To configure a VLAN:

configure vlan type=port vlan type=port

To add VLANs:

add id=<vlan Id> [name=<vlan name>] port=<numberlistrange>

To start VLANs:
