Configuring VLANs
A virtual LAN (VLAN) is a group of network devices on one or more
network segments configured such that they can communicate as if they
are on the same LAN. VLANs are based on logical instead of physical
connections and so enable greater flexibility in network design.
The most fundamental benefit of VLANs is the ability to create
workgroups of users based on function rather than on physical location or
media. For further information, see Appendix D, “Virtual LANs (VLANs).”
To configure VLANs, do the following:
1.
Select Switch Configuration Menu from the Main Menu.
2.
Select VLAN Configuration Menu.
3.
Turn the global switch VLAN operation on or off by toggling the VLAN
Enable option by pressing a.
4.
Select VLAN Menu.
The VLAN Menu displays. This menu displays the current configura-
tion of VLANs in the system.
5.
To delete a current VLAN, select Delete, then enter the number of the
VLAN.
6.
To configure a VLAN, select Configure and enter a VLAN number. A
new VLAN can be created this way.
The VLAN #n Configuration Menu displays. From this menu, you can
configure VLAN names, add/delete ports in a VLAN, and add/delete
egress ports for a VLAN.
7.
From the main VLAN Configuration Menu, select VLAN Port Menu to
configure the VLAN port mode (hybrid or access) for individual ports.
Configuring Spanning Tree parameters from their de-
fault can cause serious deterioration of network per-
formance.
