Static Route Edit
Use this screen to configure the required information for a static route. Select a static route
index number and click
Edit
. The screen shown next appears.

LABEL
DESCRIPTION
Active
This field allows you to activate/deactivate this static route.
Route Name
Enter the name of the IP static route. The text may consist of up to 9 letters,
numerals and any printable character found on a typical English language
keyboard. Leave this field blank to delete this static route.
Destination IP
Address
This parameter specifies the IP network address of the final destination.
Routing is
always based on network number. If you need to specify a route to a single host,
use a subnet mask of 255.255.255.255 in the subnet mask field to force the network
number to be identical to the host ID.
IP Subnet Mask
Enter the IP subnet mask here.
Gateway Type
Use either
Gateway Address
or
Gateway Node
to configure a static route.
Gateway IP
Address
This field is available when you select
Gateway Address
from
Gateway Type
.
Enter the IP address of the gateway. The gateway is a router or switch on the same
network segment as the device's LAN or WAN port. The gateway helps forward
packets to their destinations.
Gateway Node
This field is available when you select
Gateway Node
from
Gateway Type
.
Select a remote node to set the static route. A remote note is a connection point
outside of the local area network. One example of a remote node is your connection
to your ISP. See
Section 5.3 on page 75
for details on configuring a remote node.

802.1Q/1P
14.1
Overview
This chapter describes how to configure the 802.1Q/1P settings.
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into
multiple logical networks. A VLAN group can be treated as an individual device. Each group
can have its own rules about where and how to forward traffic. You can assign any ports on the
ZyXEL Device to a VLAN group and configure the settings for the group. You may also set
the priority level for traffic trasmitted through the ports.

What You Can Do in the 802.1Q/1P Screens
Use the
Group Setting
screen (
Section 14.2 on page 219
) to activate 802.1Q/1P, specify
the management VLAN group, display the VLAN groups and configure the settings for
each VLAN group.
Use the
Port Setting
screen (
Section 14.3 on page 222
) to configure the PVID and assign
traffic priority for each port.
14.1.2
What You Need to Know About 802.1Q/1P
IEEE 802.1P Priority
IEEE 802.1P specifies the user priority field and defines up to eight separate traffic types by
inserting a tag into a MAC-layer frame that contains bits to define class of service.
IEEE 802.1Q Tagged VLAN
Tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN
membership of a frame across bridges - they are not confined to the device on which they were
created. The VLAN ID associates a frame with a specific VLAN and provides the information
that devices need to process the frame across the network.

PVC
A virtual circuit is a logical point-to-point circuit between customer sites. Permanent means
that the circuit is preprogrammed by the carrier as a path through the network. It does not need
to be set up or torn down for each session.
Forwarding Tagged and Untagged Frames
Each port on the device is capable of passing tagged or untagged frames. To forward a frame
from an 802.1Q VLAN-aware device to an 802.1Q VLAN-unaware device, the ZyXEL
Device first decides where to forward the frame and then strips off the VLAN tag. To forward
a frame from an 802.1Q VLAN-unaware device to an 802.1Q VLAN-aware switch, the
ZyXEL Device first decides where to forward the frame, and then inserts a VLAN tag
reflecting the ingress port's default VID. The default PVID is VLAN 1 for all ports, but this
can be changed.
Whether to tag an outgoing frame depends on the setting of the egress port on a per-VLAN,
per-port basis (recall that a port can belong to multiple VLANs). If the tagging on the egress
port is enabled for the VID of a frame, then the frame is transmitted as a tagged frame;
otherwise, it is transmitted as an untagged frame.
14.1.3
802.1Q/1P Example
This example shows how to configure the 802.1Q/1P settings on the ZyXEL Device.
Figure 126
802.1Q/1P Example
LAN1 and LAN2 are connected to ATAs (Analogue Telephone Adapters) and used for VoIP
traffic. You want to create high priority for this type of traffic, so you want to group these
ports into one VLAN (VLAN2) and then to a PVC (PVC1) where the priority is set to high
level of service.
