Configuring Vlan Interfaces On Suse Linux - Novell LINUX ENTERPRISE SERVER 10 SP2 - INSTALLATION AND ADMINISTRATION Installation Manual

30.5 Configuring VLAN Interfaces on
SUSE Linux
VLAN is an abbreviation of Virtual Local Area Network. It allows the running of
multiple logical (virtual) ethernets over one single physical ethernet. It logically splits
the network into different broadcast domains so that packets are only switched between
ports that are designated for the same VLAN. If you intend to use VLAN in your network
setup, make sure that the package vlan is installed.
If the network connection of Linux is not dedicated to a specific logical LAN, you can
set up access to one or more of these logical LANs. The VLAN interface configuration
is supported via the normal ifup and ifdown scripts used for all other network interfaces,
as well. The setup of VLAN devices is supported by YaST.
