Application Notes

Setting up different DSL port speeds to different subscribers

An ISP may want to configure a different line speeds for each DSL port. This can be

easily and efficiently done in the ZyXEL IES-5000 using profiles. You can configure

line profiles with different parameter settings based on the user requirements and

apply the profile to one or more subscriber ports.

In this application example, we will show you how to create two profiles -one for low

speed requirements with an upstream/downstream bandwidth of 2M/512Kbps and the

other for high speed requirements with an upstream/downstream bandwidth of

25M/1Mbps.

For this example, you want to provide low line speed to subscribers on ports 1 to 24

and high line speed to business subscribers on ports 25 to 48.

Configuring and applying the profiles to subscriber ports

For this example, we will use configure the profile on an IES-5000 that connects to

ADSL CPEs (ZyXEL Prestige 660R-61).

1. IES-5000

1.1 Profile Setup

Configure a profile to set low line speed. Enter a descriptive name for this profile (for

example, “Profile_LowSpeed”) and set the maximum upstream and downstream rates

(for example, 512Kbps and 2048Kbps).

Similarly, configure a profile to allow a high line speed. Enter a descriptive name for

the profile (for example, “Profile_HighSpeed”) and set the maximum upstream and

downstream rates (for example, 1280Kbps and 24992Kbps).

Configuration example using the CLI:

a.)High Speed (1M/24M) profile setup:

MSG1000G> profile adsl set 1_24M 1024 24576 minrate 64 64 delay 20 20 usmgn

310 0 60 dsmgn 310 0 60 usra startup 90 30 dsra startup 90 30

b.) Low Speed (512k/2M) profile setup:

MSG1000G> profile adsl set 512_2M 512 2048 minrate 64 64 delay 20 20 usmgn

310 0 60 dsmgn 310 0 60 usra fixed 90 30 dsra startup 90 30

Save current configuration

MSG1000G> config save

1.2 Profile Assignment

Select and assign Profile_LowSpeed to port 1. After setting port 1, copy the settings

of port 1 to ports 2 to 24.

Assign Profile_HighSpeed to port 25. You also can set the port to use the ADSL2+

mode. Then, similarly, copy the settings of port 25 to the ports 26 to 48.

CI command:

MSG1000G> port adsl set 7-1~24 512_2M auto

MSG1000G> port adsl set 7-25~48 1_24M auto

MSG1000G> port enable 7-1~48

MSG1000G> port pvc set 7-1~48-0/33 DEFVAL llc 1 0

MSG1000G> config save

2. Prestige 660R-61

Next configure the CPE device. Set the Prestige 660R-61 to work in bridge mode

using the VPI/VCI settings of 0/33 (the default on IES-5000). Since the Prestige

IES-5000 Support Notes

660R-61 has a built-in telnet server, you can telnet and log into the management

interface.

2.1 Menu 1: General Setup

Go to Menu 1 to set the Prestige 660R-61 in bridge mode. In this menu, select No in

the RouteIP field and Yes in the Bridge field.

2.2Menu4:InternetAccessSetup

For bridge mode, select RFC 1483 in the Encapsulation field with LLC-based

multiplexing. Also set the Prestige to use the same VPI and VCI settings as the

IES-5000 (the default is 0 and 33 respectively).

2.3 Menu11.1: Remote Node Profile

In menu 11.1, select Yes in the Active field to activate this remote node profile. Make

sure the encapsulation and multiplexing settings are the same as in menu 4. Select Yes

IES-5000 Support Notes

in the Edit ATM Options field and press [ENTER] to enter menu 11.6.

2.4 Menu11.6: Remote Node ATM Layer Options

Make sure the VPI and VCI settings are the same as on the IES-5000 (the default is 0

and 33 respectively).

Configuring 802.1Q VLAN

A VLAN (Virtual Area Network) allows a physical network to be partitioned into

multiple logical networks. Stations on a logical network belong to one group called

VLAN group. A station can belong to more than one group. The stations on the same

VLAN group can communicate with each other. With VLAN, a station cannot directly

talk to or hear from stations that are not in the same VLAN groups.

In this application, we will show you how to configure an 802.1q VLAN. The

following figure shows a VLAN network example where two computers (PC1 and

PC2) are connected to ports 1 and 2 on the line card. Each computer belongs to a

different VLAN (VLANs 10 and 20). Therefore the computers cannot communicate

directly to each other. However, PC1 and PC2 still need connection to the Internet.

Setting up a VLAN

For this application, we will use an IES-5000 and Prestige ADSL660R-61 CPE (any

DSL CPE or P791 if you have the SLC-1248G line card installed on the IES). Since

the two ports belonging to different VLANs need Internet access via the Uplink port

on the IES-5000, another VLAN (to which the two ports are a member of) need to be

configured.

1. IES-5000 Settings

1.1 VLAN settings

Create a VLAN group with VID 10 and set Port 1, ENET1 and ENET2 to be members

of this VLAN.

CI command:

TGE1> vlan set 10 up1 fix untag

TGE1> vlan set 10 up2 fix untag

TGE1> vlan name 10 VLAN10

TGE1> port pvc vlan 7-1-0/33 10 join untag

Create a VLAN group with VID 20 and set Port 2, ENET1 and ENET2 to be members

of this VLAN.

CI command:

TGE1> vlan name 20 VLAN20

TGE1> vlan set 20 up1 fix untag

TGE1> vlan set 20 up2 fix untag

TGE1> port pvc vlan 7-2-0/33 20 join untag

Create a VLAN group with VID 200 and set slot 7, Port 1, Port 2, ENET1 and ENET2

to be members of this VLAN.

CI command:

TGE1> vlan name 200 VLAN200

TGE1> vlan set 200 up1 fix untag

TGE1> vlan set 200 up2 fix untag

TGE1> port pvc vlan 7-1-0/33 200 join untag

TGE1> port pvc vlan 7-2-0/33 200 join untag

1.2 PVID settings

After creating the three VLANs, you need to set the PVID on the ports.

IES-5000 Support Notes

For this example, assign VLAN 200(PVID) to ENET1 and ENET2. Also, assign

VLAN 10 and VLAN 20 to Port1 and port2 respectively.

CI command:

TGE1> switch port pvid up1 200

TGE1> switch port pvid up2 200

TGE1> port pvc set 7-1-0/33 DEFVAL llc 10 0

TGE1> port pvc set 7-2-0/33 DEFVAL llc 20 0

1.3 Port Isolation

On the IES-5000, you can isolate ports without configuring VLAN groups in the CLI.

CI command:

TGE1> switch isolation enable

2. Prestige 660R-61(P791) Settings

Please refer to the steps in the previous application.

Triple play Application

On the IES-5000, you can use different channels (also known as Permanent Virtual

Circuits or PVCs) for different services. Define channels on each DSL port for

different services and assign each channel a priority, VLAN and ATM Quality of

Service (QoS). The ATM QoS allows you to regulate the average rate and fluctuations

in data rates. This helps eliminate congestion and to allow smooth transmission of real

time data (such as audio and video).

In this application, we will show you how to set up multiple PVCs using the IES-5000.

The following figure shows a network example where the computers want to get

different services (data service for Internet access and video service) from two

networks. Since a smooth video streaming quality is desired, we want to give the

video service a higher priority. To do this on the IES-5000, create a different VLAN

for each service and configure the PVCs with a different VID, priority and ATM QoS.

This allows the video service to have a higher priority over the data service. You can

easily adapt this application for a triple-play service network.

IES-5000 Support Notes

Setting up Multiple PVCs

This section shows you how to configure settings on the devices for this application.

In this network application, we will use an IES-5000, a ZyXEL ES-2024

VLAN-aware switch and Prestige 660R-61 CPE (you may also use P791 if you have

the SLC-1248G line card installed on the IES).

1. IES-5000 Settings

1.1 VLAN setup

Follow the procedure as described in the VLAN Application section to configure the

VLAN settings on the IES-5000.

Create a VLAN with a VID of 10 and set Port 1 and ENET 1 to be members of this

VLAN. Also enable egress tagging on ENET 1.

TGE1> vlan name 10 VLAN10

TGE1> vlan set 10 up1 fix tag

TGE1> port pvc vlan 7-1-0/33 10 join untag

Create a VLAN with a VID of 20 and set Port 1 and ENET 1 to be members of this
