Vlan Management Overview - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

Configuring VLANs

VLAN Management Overview

One of the main benefits of using VLANs to segment network traffic, is that VLAN configuration and port
assignment is handled through switch software. This eliminates the need to physically change a network
device connection or location when adding or removing devices from the VLAN broadcast domain. The
VLAN management software handles the following VLAN configuration tasks performed on an
Alcatel-Lucent switch:
•
Creating or modifying VLANs.
•
Assigning or changing default VLAN port associations (VPAs).
•
Enabling or disabling VLAN participation in the current Spanning Tree algorithm.
•
Enabling or disabling classification of mobile port traffic by 802.1Q tagged VLAN ID.
•
Enabling or disabling VLAN authentication.
•
Defining VLAN IPX router interfaces to enable routing of VLAN IPX traffic.
•
Enabling or disabling unique MAC address assignments for each router VLAN defined.
•
Displaying VLAN configuration information.
In addition to the above tasks, VLAN management software tracks and reports the following information
to other switch software applications:
•
VLAN configuration changes, such as adding or deleting VLANs, modifying the status of VLAN prop-
erties (e.g., administrative, Spanning Tree, and authentication status), changing the VLAN description,
or configuring VLAN router interfaces.
•
VLAN port associations triggered by VLAN management and other switch software applications, such
as 802.1Q VLAN tagging and dynamic mobile port assignment.
•
The VLAN operational state, which is inactive until at least one active switch port is associated with
the VLAN.
