Network Diagram

Figure D-1 illustrates an example network of Ericsson DSL equipment. A Public Ethernet Manager (PEM) terminal communicates with an Ethernet Controller Node (here an ECN320), which in turn aggregates traffic from one or more Ethernet DSLAM Nodes (here an EDN312xp DSLAM). The DSLAM, in turn, communicates with an HM340d home access gateway (HAG).

Table D-1 lists the VLANs, their descriptions, and addresses for the ECN320 and EDN312xp DSLAM. Table D-2 lists the configuration parameters for the HM340d.

Note For more information on these configurations, see the document Ericsson EDA Network and System Administration.


Configuring the HAG

Two files are used to configure the Ericsson HM340d HAG:

atm.conf describes the ATM permanent virtual circuits (PVCs) that are configured in the HAG, allowing PVC Ethernet frames to be bridged in accordance with RFC 2684. This filed is used for both the user profiles that are created. (See Creating Services and Profiles.)

bridge.conf maps the ports on the HAG to a specific VLAN/PVC number. This filed is copied and edited as appropriate for both the user profiles that are created.


Note For HAG configuration parameters, see Table D-2. For more information, refer to the document Ericsson Service Gateway HM340d Operator's Guide.


Because the HAG configuration files used in the solution are not the Ericsson defaults, you must edit the default files to configure the HAG to forward the three VLANs and services. This information is part of the DSLAM service configurations, and must also be included in the HAG configuration.


Note Data is on port 1, voice is on port 2, and video is on ports 3 and 4. The DSLAM ports are physically labeled 1 through 4 on the outside of the HAG, although in the file bridge.conf these numbers correspond to 0 through 3.


Edit the default files to conform to the following.

atm.conf

The following shows the atm.conf file used for both user profiles.

# atm.conf -- ATM PVC configuration

# Each line in this file will result in a ATM PVC being configured, and on this PVC ethernet frames will be bridged (RFC 2684).


# ATM PVC Interface number 0 (zero) is the management PVC.

bridge.conf

The following shows the bridge.conf file used for Profile1.

# bridge.conf -- virtual/software ethernet bridge configuration


# The information in this file determines which logical ethernet bridges should be present.


# Each line is a bridge with the members as a space-separated list, were each member is either a PVC or a tagged or untagged ethernet port. A PVC member is listed as "pvcN" where N is the ATM PVC identifier from the /etc/atm.conf configuration file. An untagged port member is listed as "portN", and a tagged port as "tagged-portN", were N is the port number (0-3, inclusive).

Each logical port (PVC, tagged or untagged ethernet port) may only be a member of one bridge. If one untagged port (for example "port2") is used, the corresponding tagged port ("tagged-port2") may not be used, and vice versa.


# VLAN id Members

   90 port0           pvc1

   120 port2           pvc7

   121 port1           pvc4

The following shows the bridge.conf file used for Profile2. Note the addition of port 3.

# bridge.conf -- virtual/software ethernet bridge configuration


# The information in this file determines which logical ethernet bridges should be present.


# Each line is a bridge with the members as a space-separated list, were each member is either a PVC or a tagged or untagged ethernet port. A PVC member is listed as "pvcN" where N is the ATM PVC identifier from the /etc/atm.conf configuration file. A untagged port member is listed as "portN", and an tagged port as "tagged-portN", were N is the port number (0-3, inclusive).

Each logical port (PVC, tagged or untagged ethernet port) may only be a member of one bridge. If one untagged port (for example "port2") is used, the corresponding tagged port ("tagged-port2") may not be used, and vice versa.

EAN Name: ECN320-192-168-1-100

MDF Position: 1.0.1

e. Select Line Activate and Apply to activate User101 with the line and service configuration.


Note The connection status LED on the PEM should be green.

Step 4 Add data service.

a. In the Add Customized Services window, click Add.

b. From the drop-down menu, choose Data.

c. Under Bandwidth, choose DataBW.


Note No IP address is required because a transparent VLAN for data service is used. A filter is not applicable.


d. Set the EDN Name and EDF position used by the PEM to identify the line configuration for this user:

EDN Name: ECN320-192-168-1-100

MDF Position: 1.0.2

e. Select Line Activate and Apply to activate User102 with the line and service configuration.


Note The connection status LED on the PEM should be green.



Creating an IP Filter

If a static IP address is used as part of a video, voice, or data service configuration, an IP filter must be applied for the static IP address to work. Ericsson does not provide a default filter that allows all addresses in the downstream direction to be passed through to the HAG. At least one IP address must be entered into the filter, with that IP address to be marked as "allow" or "deny." Because the range command is not supported in the filter configuration in the downstream direction, each address through which traffic is allowed to pass must be entered individually into the filter.

A workaround is to create a filter that denies only one IP address in the downstream direction. The IP address to deny can be any IP address that will not be used to send to, or receive from, the HAG attached to the DSLAM line port for this service configuration. This solution is easier than attempting to add all the IP addresses of all devices that will be sending to, or receiving from, the device attached to the port of the HAG.

Do the following to create an IP filter.


Step 1 Using the Ericsson PEM configuration application, choose Service Configuration > New EDA Filter.

Step 2 Under Configuration name, enter FilterAll.

Step 3 Uncheck the box labeled "ICMP security enabled."

Step 4 Create an upstream filter to allow a range of IP addresses.

a. Select the Up Stream tab.

b. Enter 192.168.0.0 - 255.255.255.255

c. Click Allow.

d. Click OK.

Step 5 Create a downstream filter to deny one IP address and allow all other addresses.

a. Select the Down Stream tab.

b. To create a filter that allows any IP addresses except the following (any IP address not used in the system), enter 172.2.2.2.

c. Click Deny.

d. Click OK.

Step 6 Assign the filter to the desired service and line configuration.


Special Issues

Note the following special issues:

1. If multicast (broadcast) video is to be delivered to the STB through the DSLAM, the Service Configuration for Video must have IGMP snooping enabled.

2. At the time of this printing, Ericsson DSL equipment does not support IGMP version 3. If IGMPv3 commands are sent to the Ericsson equipment, messages are discarded and the broadcast is not played through the STB. Consequently, Cisco switches connected to the Ericsson ECN320 switch must send IGMPv2 commands to the Ericsson equipment.
