CHAPTER 16
VLAN
This chapter discusses how to configure VLAN on the ZyXEL Device.
16.1 VLAN
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network can belong to one or more groups.
Only stations within the same group can talk to each other.
16.1.1 Management VLAN ID
The Management VLAN ID identifies the “management VLAN”. A device must be a member
of this “management VLAN” in order to access and manage the ZyXEL Device. If a device is
not a member of this VLAN, then that device cannot manage the ZyXEL Device.
" If no devices are in the management VLAN, then you will be able to access the
ZyXEL Device only through the console port (not through the network).
16.1.2 VLAN Tagging
The ZyXEL Device supports IEEE 802.1q VLAN tagging. Tagged VLAN uses an explicit tag
(VLAN ID) in the MAC header of a frame to identify VLAN membership. The ZyXEL
Device can identify VLAN tags for incoming Ethernet frames and add VLAN tags to outgoing
Ethernet frames.
" You must connect the ZyXEL Device to a VLAN-aware device that is a member
of the management VLAN in order to perform management. See the Configuring
Management VLAN example BEFORE you configure the VLAN screens.
