Application Notes

IES 1248 Support Notes

Provide Different DSL Port Speeds to different subscribers

An ISP may provide different Line speeds for each DSL port. In our IES-1248 have an easy way to configure the line speed for each port. It can create some profiles which can set different parameters to meet the different users’ requirement.

In this application, we will set up two profiles. One is for low speed requirement with upstream/downstream is 2M/512Kbps and the other is for high speed requirement with upstream/downstream is 25M/1.2Kbps. We suppose there are general subscribers from port 1 to port 24 with a low speed profile and some enterprise users from port 25 to port 48 with high speed profile.

2. Prestige 660R-61 Settings

We configure Prestige 660R-61 as bridge mode. The default VPI/VCI of

IES-1248 is 0/33. So we need to set up such values. Prestige 660R-61 has a

Telnet server inside. We need to configure it via Telnet.

2.1 Menu1: General Setup

Go to Menu 1. In this menu, we must set “Rout IP = NO” and “Bridge = YES”.

2.2 Menu4: Internet Access Setup

The encapsulation must be RFC 1483 for bridge mode. The Multiplexing should be the same as IES-1248. The LLC-based is default mode of IES1248. Additionally, we must check if the VPI/VCI is the same as IES-1248. The default VPI/VCI of IES1248 is 0/33.

How to configure 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.

We want to deploy VALN environment in this application. The following figure shows the VLAN example. Two PCs connect to the port 1 and port 2 of the line card

10

All contents copyright (c) 2006 ZyXEL Communications Corporation.

IES 1248 Support Notes and belong to different VLAN. One is VLAN 10 and the other is VLAN 20. So they can’t communication with each other. But both PC 1 and PC 2 can connect to Internet.

1.3 Port Isolation

If we just want to isolate ports of IES-1248 and don’t want to set any VLAN, there is another easy way to do this. Click Basic setting, Switch Setup in navigation panel to display configuration screen as shown. Check Port isolation Active check box.

2. Prestige 660R-61 Settings

Please refer to the procedures in previous application.

Triple play Application

The IES-1248 allows you to use different channels(also called Permanent Virtual

Circuits or PVCs) for different services. Define channels on each DSL port for different services and assign each channel a priority, a VLAN and ATM Quality of

Service (QoS). The ATM QoS allows you to regulate the average rate and fluctuations of data transmission. This helps eliminate congestion to allow transmission of real time data (such as audio and video).

14

All contents copyright (c) 2006 ZyXEL Communications Corporation.

IES 1248 Support Notes

In this application, we demonstrate how to set up the multiple PVCs environment.

From the figure below, the PC wants to access the two kinds of network services. One is the Internet service (data service) and the other is Video service. Because we hope we can see the video smoothly, we need to set the video service higher priority. In

IES-1248, we can set the two services with different VLANs and assign the PVCs with different VLAN, priority and ATM QoS. That will make the video traffic get the higher priority than data traffic. We also can expand this application to triple play environment.

IES 1248 Support Notes will go via 0/34. And the 0/33 get the higher priority. The video traffic will go first when the two traffics arrive at the same time.

802.1x Application

IEEE 802.1x port-based authentication is desired to prevent unauthorized ports

(clients) from gaining access to the network. It is an extended authentication protocol that allows support of RADIUS (Remote Authentication Dial in User Service,

RFC2138, 2139) for centralized user profile management on a network RADIUS server.

We want to deploy 802.1x environment in this application. The following figure shows the 802.1x example. PC1(supplicant) and PC2(supplicant) want to access to the application server. If PC1 is not unauthorized, the traffic from PC1 to application server will be blocked. If PC2 is an authorized client, then it can access to the application server. From the figure, IES1248 acts as an authenticator.

Setting up the IGMP Snooping/IGMP Filtering

Without IGMP snooping multicast traffic is treated in the same manner as broadcast traffic, that is, it is forwarded to all port. With IGMP snooping, multicast traffic of a group is only forwarded to ports that have members of that group. IGMP snooping generates no additional network traffic, allowing you to significantly reduce multicast traffic passing through the IP-DSLAM. IGMP filtering is for allowing a port to join some specific IGMP groups. This can be applied in Video service providers. They can only open some specific channels (groups) to specific ports.

How to set up IGMP snooping/IGMP filtering

IES 1248 Support Notes

Here, we only set up the IES1248 to support IGMP snooping and IGMP filtering.

Please refer to the user guide of the Video Server and the subscriber device. We assume the video server provides three channels, movie 1 on 240.10.10.8 group, movie 2 on 240.10.10.9 group and movie 3 on 240.10.10.10 group. And we assume the subscriber want to subscribe two channel, movie 1 and movie 2. If we don’t enable the IGMP snooping, every one can see all movies. If we don’t set the IGMP filtering on the port, the subscriber behind the port will receive all movies.

1. IES-1248 settings

1.1 Enable IGMP Snooping

Click IGMP setup on IGMP Snooping page and enable the IGMP snooping. After a while, you will see the number of Query will increase when IES-1248 receives the query packet from IGMP router.

Meanwhile, if the subscriber sends the join packet, we can see the number of Report will increase and the IGMP table will be created.

38

All contents copyright (c) 2006 ZyXEL Communications Corporation.

1.2 Set up IGMP Filtering

IES 1248 Support Notes

If we don’t set up IGMP filtering, the subscriber will receive all the movies. We set up a IGMP filter Profile and apply it to specific port to limit the channels subscriber can see. Click Basic Setting, xDSL Profiles Setup in the navigation panel to display configuration screen as shown. And click the IGMP Filter Profile to show the setup page.

In this case we only allow the subscriber to join movie 1 and movie 2. That means only the groups 240.10.10.8 and 240.10.10.9 can be forwarded this subscribed port.

After create this profile, there is a new profile added in the list.

Then we need to apply the profile to port 1. Click Basic Setting, xDSL Profiles

Setup in the navigation panel to display configuration screen as shown. Click the port index 1 to set up this port.

39

All contents copyright (c) 2006 ZyXEL Communications Corporation.

IES 1248 Support Notes

We select the Subscriber1 in IGMP Filter Profile Combobox. And click Apply to let the setting take effect.

Go back to check the IGMP Snooping table. We will see only two channels allowed to be forwarded to port 1.

Static Multicast

What is Static Multicast Filter?

Static Multicast Filter allow network administrator to configure multicast group consisting of one or more ranges of MAC multicast addresses. An administrator can control multicast traffic per-switch-port basis with static multicast filter. By default, all multicast traffic are dropped without static multicast filter setup or IGMP snooping which cause some routing protocol such as RIPv2 and OSPF can not be passed through IP DSLAM. So administrator must do any configuration of static multicast filter to pass such routing protocol and other related application smoothly.

Some Well-known multicast group address:

224.0.0.1---------all systems on this subnet

IES 1248 Support Notes

224.0.0.2---------all routers on this subnet

224.0.0.5---------all routers running OSPF

224.0.0.6---------all Designed Routers running OSPF

224.0.0.9---------for RIPv2

224.0.1.1---------for NTP

Before using static multicast filter, you must mapping Multicast IP address to

Multicast MAC address because IES IPDSLAM using Multicast MAC address to forwarding multicast traffic.

This feature can also be combined with IGMP Snooping feature to make ports know multicast traffic that are not learned by IGMP Snooping or forbid specified ports to receive multicast traffic learned by IGMP Snooping.

Application Scenario

Scenario Description

All contents copyright (c) 2006 ZyXEL Communications Corporation.

41

IES 1248 Support Notes

An ISP wants to provide multicast video service to end user and subscribes who with different pay enjoy different programs.

Client A (connect to ADSL port 1) is a normal subscribe, so he has no authority to access movie resource.

Client B (connect to ADSL port 2) is a pay subscribe, he has authority to access limited movie resource (for example, just only channel 1).

Client C (connect to ADSL port 3) is a VIP subscribe, so he has the highest authority to access all movie resource (for example, both channel 1 and 2)

Static Multicast Filters can specify which video channels (based on multicast

MAC addresses) are allowed or denied to be received by each subscribe.

The Multicast traffic MAC address of different channels as follows

IGMP Query: 01:00:5E:00:00:01 (224.0.0.1)

IGMP Report: 01:00:5E:00:00:02 (224.0.0.2)

Channel 1 multicast MAC address: 01:00:5E:01:01:01 (224.1.1.1)

Channel 2 multicast MAC address: 01:00:5E:02:02:02 (224.2.2.2)
