62 Configuring & Monitoring the Switch ELS100-24TXM
Configuring VLANs
A virtual LAN (VLAN) is a group of devices on one or more LANs that are
configured such that they can communicate as if they were attach ed to
the same wire. Because VLANs are based on logical instead of physical
connections, they are extremely flexible.
The most fundamental benefit of VLAN technology is the ability to create
workgroups 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 Class of Service
You can configure Class of Service parameters using the Class of Servic e
Configuration Menu. This menu permits you to configure priority level s to
traffic being forwarded through the switch. During periods of congestion,
Class of Service settings ensure that traffic which has been assigned high
priority is forwarded through the switch ahead of normal priority traffic. For
further information, see Appendix E, “Class of Service.”
