Configuring Vlans; Chapter 4 Configuring Vlans; In This Chapter - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

In a flat bridged network, a broadcast domain is confined to a single LAN segment or even a specific
physical location, such as a department or building floor. In a switch-based network, such as one
comprised of Alcatel-Lucent switching systems, a broadcast domain—or VLAN— can span multiple
physical switches and can include ports from a variety of media types. For example, a single VLAN could
span three different switches located in different buildings and include 10/100 Ethernet, Gigabit Ethernet,
802.1q tagged ports and/or a link aggregate of ports.

In This Chapter

This chapter describes how to define and manage VLAN configurations through the Command Line
Interface (CLI). CLI commands are used in the configuration examples; for more details about the syntax
of commands, see the OmniSwitch CLI Reference Guide.
