SC Connector
The trunk interface is made with the SC connector, which is available in two types:
Gigabits Ethernet optical long haul LX single mode interface.
Gigabits Ethernet optical short haul SX multimode interface.
For each type of optical transceiver, they should connect with corresponding optical
fiber with proper mode. Incorrect fiber mode may affect link distance or even link fail.
Fiber for long haul LX: Single-mode (SM), 9/125 micron.
Fiber for short haul SX: Multi-mode (MM), 50/125 or 62.5/125-micron.
The two types of interface are visually and functionally similar. Installation
procedures are the same. This dual port has both connectors on transmit (upstream)
and a receiving (downstream) as shown in Figure 1-18. There are warnings for the
optical fiber connection.
Warning
The laser energy of the fiber optic communication channels in the single-mode
will be harmful when operate, especially to the eyes. During normal operation
with cable connection, this energy is confined to the cable with no danger present.
Because the laser radiation is invisible and may be emitted from the aperture of
the port before connect the cable or protective cap, please avoid exposure to laser
radiation and also do not fix the gaze to open apertures.
The following precautions are to avoid injury when connecting or disconnecting
optical channel.
Always connecting optical cables before power on.
Always keep the protective cap on the optic connector.
Never stare into an optical cable or connector when the connector is not in use.
Connect the fiber channel using the following steps:
Step 1 Read and understand the previous warnings and alarm.
Step 2 Remove the protective caps from the fiber optic connector and from the
external data cable.
Step 3 Attach the external cable to the recessed connector on the faceplate as shown
on Figure 1-18.

IP DSLAM Product Feature
This chapter is divided into the following sections,
Section 3.1: Introduction
Section 3.2: Quality of Service (QoS)
Section 3.3: Security
Section 3.4: Packet Filtering
Section 3.5: ATM Features
Section 3.6: Miscellaneous
3.1 Introduction
CHAPTER
3
The IP DSLAM (Integrated Ethernet Switch) is an IP-based DSLAM (Internet Digital
Subscriber Line Access Multiplexer) that connects to 24 ADSL subscribers to the
Internet. When deployed together with DSL modems and WAN routers, the
combination forms are integrated solution for providing broadband services to
multiple tenants such as apartments, hotels, offices and campus buildings. IP DSLAM
supports a lot of features as listed below.
ADSL Access Module
The name marked “Line” on the front panel is a RJ-21 connector integrated 24 ADSL
ports internally. It aggregates traffic from 24 lines to Ethernet port(s) and has
integrated splitters to allow voice and ADSL to be carried over the same phone line
wiring.
10/100 Mbps Auto-negotiating Ethernet Port
IP DSLAM supports two 10/100/1000 Mbps auto-negotiate Ethernet ports connects to
an Ethernet network. It can be aggregated together as a logical port as the backbone,
and provide ADSL service to lots of subscribers.
There are three features supported for bridge function.
IEEE 802.1d STD transparent bridging
Up to 4000 MAC entries address table
Port-based VLAN
IEEE 802.1Q Tagged VLAN
IP DSLAM uses the IEEE 802.1Q Tagged VLAN; users can allow this device to
deliver tagged/untagged frames in these ports. The IP DSLAM supports up to 512
VLAN groups and can be applied up to 4094 VLAN identifications.
IEEE 802.1p Priority
IP DSLAM supports IEEE 802.1p to assign priority levels to all individual ports.
Users can set different quality of service for individual application.
For example, voice and video services can set high priority and Internet data service
will be lower priority.
Support 4 queues for per ATM port.
Support 8 queues for per physical Ethernet port.
MAC Address (Media Access Control) Filter
IP DSLAM can let users use the MAC filter for incoming frames based on MAC
(Media Access Control) addresses that specified by users. Users can enable/disable
this function on specific port.
Access Control List per port is up to 8 entries. If port receives a packet which
source MAC address is met with one of the 8 entries, this packet can be forwarded
to destination port.
46
Page 47
VigorAccess User Installation Guide
Access Control List per device is up to 1024 entries. If port receives a packet
which source MAC address is met with one of these entries, this packet would not be
forwarded to destination port.
The high priority of ACL rules is the allowing rule checking for per port.
MAC Address (Media Access Control) Count Filter
IP DSLAM supports users to limit the number of MAC addresses that may be
dynamically learned or statically configured on a port. Users can enable/disable this
function on individual ports.
The global static learning table has up to 512 entries. Each entry can be set to a
specific port. In dynamic learning mode, there are 16 MAC address entries in DSL
port and 256 entries in Ethernet uplink port.
Multi-Protocol Encapsulation
IP DSLAM supports multi-protocol encapsulation over ATM adaptation Layer 5
based on RFC2684.
Management
IP DSLAM supports some management method as listed below.
Remote configuration backup/restore via EMS client/server.
Remote firmware upgrade
SNMP management
Command Line Interface, it can be accessed by local Console or Telnet interface.
Multiple PVC on single port
IP DSLAM allows you to use different virtual connection also called PVC (Permanent
Virtual Circuits) for different services or subscribers. Users can define up to 8
connections on each DSL port for different services or levels of service, and users can
assign different priority for each connection.
IGMP Snooping
IGMP (Internet Group Management Protocol) snooping reduces multicast traffic for
maximum performance. The feature is very popular for video multicast application for
example IPTV service.
47
Page 48
VigorAccess User Installation Guide
3.2 Quality of Service (QoS)
Quality of Service (QoS) refers to the capability of a network to provide better service
to select network traffic over various technologies. The primary goal of QoS is to
provide priority including dedicated bandwidth, controlled jitter and latency (required
by some real-time and interactive traffic), and improved loss characteristics. Also it is
important to make sure that providing priority for one or more flows does not make
other flows fail. QoS technologies provide the elemental building blocks that will be
used for future business applications in campus, WAN and service provider networks.
3.2.1 Prioritized Bridging
IP DSLAM supports for multiple queues per port. There are different queues both on
ATM and Ethernet uplink.
Four queues supported per ATM port.
Eight queues supported per physical Ethernet port.
IP DSLAM supports rate-limiting function in input/output both direction.
Input Rate Limiting (IRL) on a per-AAL5 interface.
Output Rate Limiting (ORL) on a per ATM-port basis
Output Rate Limiting (ORL) on a per-physical Ethernet Interface basis.
One feature supports for buffer admission control triggered using IRL. Moreover, it
also supports for dynamic modification of ORL on ATM and Ethernet interfaces.
3.2.4 Mapping Table
IP DSLAM supports a packet priority to traffic class mapping table supported on a per
egress bridge port.
48
Page 49
VigorAccess User Installation Guide
3.2.5 Multiple Mechanisms
IP DSLAM supports two multiple mechanisms as below.
Multiple mechanisms of prioritizing incoming traffic are based on a per-bridge
port.
(1) Using Source Port configuration (for untagged packets)
(2) Using Packet Classifier actions
(3) Using priority regeneration table (mapping ingress priority to egress priority)
(4) Combination of the above
Multiple mechanisms of 802.1p re-tagging of outgoing traffic is based on a per
ingress bridge port.
(1) Using Source Port configuration (for untagged packets)
(2) Using Classifier actions
(3) Using priority regeneration table (mapping ingress priority to egress priority)
(4) Combinations of the above
3.2.6 Abilities
IP DSLAM can be able to create multiple scheduling profiles, either Strict Priority or
Probabilistic Priority. It also can be able to share the same profile across multiple
(similar) ports.
3.3 Security
IP DSLAM supports some different methods to implement this feature in following
sections.
3.3.1 Rate Limitation
IP DSLAM supports a function for throttling flooded packets. Users can configure
some limited rates by per-port.
49
Page 50
VigorAccess User Installation Guide
3.3.2 Static Mac Address
IP DSLAM supports this feature to be configured with certain ports to learn MAC
addresses on a semi-permanent basis. These learned entries would be treated similar
to the static entries, but will not be subject to aging or overwriting. These only may be
deleted explicitly by management or by making the ports, as non-static after aging
will happen normally.
3.3.3 FDB Conflicting Traps
IP DSLAM will transmit a trap packet to central manager when any MAC address
moves from one port to another port.
3.3.4 MAC Address Tracking
IP DSLAM can be configured to track a global list of MAC addresses. When these
MAC addresses move from one port to another port, a trap is generated. Whether
packets from a particular bridge port should be subjected to this tracking is
configurable. This may be used to prevent denial of service from certain MAC
addresses.
3.3.5 Access Control List by MAC address
This feature can be configured by per-port. It also supports a MAC address deny list,
the application of the MAC address deny list can be enabled/disabled on a per bridge
port basis.
3.3.6 Access Control List by IP Address
This feature still can be configured by per-port, and enabled/disabled on a per bridge
port basis.

VigorAccess User Installation Guide
3.4 Packet Filtering
This function is provided for users to setup some rules to filter the specific packets
while receiving packets from logical ports.
IP DSLAM supports for rule-based packet filtering, it can be used to implement
filtering required of NetBeui, NetBIOS, DHCP, 802.1x and other protocols.
3.4.1 Filtering Modes
IP DSLAM supports for independent rule ordering and rule ID. It means that rule ID
no longer determines the order in which the rule is applied. The rule can be modified
easily; users can replace a rule sequence of a stage on an interface by another
sequence in one step.
Moreover, IP DSLAM also supports for capturing unicast and multicast packets that
fail lookup in the forwarding database is provided. Users may write their own
applications to terminate and act on this information. On the other side, it also
supports for capturing packets coming to Control Plane that do not match any
registered filter.
3.4.2 Classifier Tree
IP DSLAM provides tree architecture for classification. This tree is now configurable
as a generic filter sub-rule.
3.4.3 Multiple Filter Stages
IP DSLAM supports a concept of multiple filter stages are provided for ingress and
egress filter rules. Moreover, IP DSLAM supports an Egress filtering for unicast,
broadcast and multicast traffic. It also supports multiple actions configurations by per
filter rule.
