Getting to Know Your
MSAP2000 AAM
This chapter introduces the main features and applications of the MSAP2000 AAM.
1.1 Introduction
The MSAP2000 AAM (ADSL Access Module) is an 12-port ADSL2+ multiplexer
network module that aggregates traffic from 12 lines to an Ethernet port and has
integrated splitters to allow voice and ADSL to be carried over the same phone
line wiring. The hot-swappable MSAP2000 AAM is designed to be installed in an
MSAP2000 SHELF, that connects ADSL subscribers to the Internet.
With its built-in web configurator, managing and configuring the switch is easy.
From cabinet management to port-level control and monitoring, you can configure
and manage your network via the web browser. In addition, the MSAP2000 AAM
can also be managed via Telnet, the console port, or third-party SNMP
management.
1.2 System Description
10/100 Mbps Ethernet Ports
The MSAP2000 AAM has two 10/100Mbps auto-negotiating, auto-crossover
Ethernet ports. That allow you to:
• Connect the MSAP2000 AAM to GbE (a second level switch) thru system
backplane
• Rear access wring to external switches
Wire-wrap post connector
There are twelve pairs of wire-wrap post connectors at the system backplane for
ADSL connection.

MSAP2000 AAM User’s Guide
IEEE 802.1p Priority
Your MSAP2000 AAM uses IEEE 802.1p Priority to assign priority levels to
individual PVCs.
Multiple PVC and ATM QoS
The MSAP2000 AAM allows you to use different channels (also called Permanent
Virtual Circuits or PVCs) for different services or subscribers. Define channels on
each DSL port for different services or levels of service and assign each channel
a priority. ATM Quality of Service (QoS) allows you to regulate the average rate
and fluctuations of data transmission. This helps eliminate congestion to allow the
transmission of real time data (such as audio and video).
IEEE 802.1x Port-based Authentication
The MSAP2000 AAM supports the IEEE 802.1x standard for centralized user
authentication and accounting management through an optional network
authentication (RADIUS) server or local user database.
Management
• Remote configuration backup/restore and firmware upgrade
• SNMP manageable
• Text-based management locally via console port and remotely via telnet
• Editable plain text based configuration file
Security
• Password protection for system management
• VLAN
MAC (Media Access Control) Count Filter
You can limit the number of MAC addresses that may be dynamically learned on
a port. You may enable/disable the MAC count filter on individual ports.
Static Multicast Filter
Use the static multicast filter to allow incoming frames based on multicast MAC
address(es) that you specify. This feature can be used in conjunction with IGMP
snooping to allow multicast MAC address(es) that are not learned by IGMP
snooping.
IGMP Snooping
With IGMP snooping, group multicast traffic is only forwarded to ports that are
members of that group. IGMP Snooping generates no additional network traffic,
allowing you to significantly reduce multicast traffic passing through your
MSAP2000 AAM.

MSAP2000 AAM User’s Guide
System Monitoring
• System status (link status, rates, statistics counters)
• Temperatures, voltage reports and alarms.
System Error Logging
The MSAP2000 AAM's system error log will record error logs locally. These
logs may be viewed again after a warm restart.
Alarm LED
An ALM (alarm) LED lights when the MSAP2000 AAM is overheated or the voltage
readings are outside the tolerance levels.
Bandwidth Control
The MSAP2000 AAM supports rate limiting in 64Kbps increments allowing you to
create different service plans.
Quality of Service
The MSAP2000 AAM has four priority queues so you can ensure missioncritical data gets delivered on time.
Follows the IEEE 802.1p priority setting standard.
1.3 Applications
1.3.1 MTU Application
These are the main applications for the MSAP2000 AAM:
• Internet access and multimedia services for Multiple Tenant Units (MTU).
• Other applications include telemedicine, surveillance systems, remote
servers systems, cellular base stations and high-quality teleconferencing.
The following diagram depicts a typical application of the MSAP2000 AAM with
ADSL modems, in a large residential building, or multiple tenant unit (MTU), that
leverages existing phone line wiring to provide Internet access to all tenants.
ADSL service can coexist with voice service on the same line.
22
MSAP2000 AAM User’s Guide
Figure 1 MTU Application
1.3.2 Curbside Application
The MSAP2000 AAM can also be used by an Internet Service Provider (ISP) in a
street cabinet to form a "mini POP (Point-of-Presence)" to provide broadband
services to residential areas that are too far away from the ISP to avail of DSL
services. Residents need an ADSL modem, connected as shown in the previous
figure.

AAM’s IP address, you must use the new IP address if you want to access the
web configurator again.
Figure 10 IP setup
6 Skip to step 15 if you have your subscribers use VPI 0 and VCI 33 (the
default for all of the ADSL ports). Otherwise, use the following steps to
change the VPI and VCI settings for all of the ADSL ports.
First you will delete the default virtual channel from all of the ADSL ports
(you cannot edit it).
Adding another virtual channel without deleting the default virtual channel is
not recommended since you cannot set the new channel to be the port's
super channel. The super channel can forward frames belonging to multiple
VLAN groups (that are not assigned to other channels). A channel that is
not the super channel can only forward frames with a single VLAN ID (that
is configured on that channel). The MSAP2000 AAM would drop any
frames received from the subscriber that are tagged with another VLAN ID.
Then you will configure a new virtual channel for a port and copy it to the other
ADSL ports

6.4 IGMP Snooping
IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to
establish membership in a multicast group - it is not used to carry user data.
Refer to RFC 1112 and RFC 2236 for information on IGMP versions 1 and 2
respectively.
A switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2)
packets transferred between IP multicast routers/switches and IP multicast hosts
to learn the IP multicast group membership. It checks IGMP packets passing
through it, picks out the group registration information, and configures
multicasting accordingly. IGMP snooping allows the switch to learn multicast
groups without you having to manually configure them.
The switch forwards multicast traffic destined for multicast groups (that it has
learned from IGMP snooping or that you have manually configured) to ports that
are members of that group. The switch discards multicast traffic destined for
multicast groups that it does not know. IGMP snooping generates no additional
network traffic, allowing you to significantly reduce multicast traffic passing
through your switch.

The switch has 4 physical queues that you can map to the 8 priority levels. On the switch, traffic
assigned to higher index queues gets through faster while traffic in lower index queues is dropped if
the network is congested.

ADSL Port Setup
This chapter explains how to configure settings for profiles and individual ADSL
ports. It also covers how to configure virtual channels and virtual channel profiles.
7.1 ADSL Standards Overview
These are the ADSL standards and rates that the MSAP2000 AAM supports at the
7.2 Downstream and Upstream
7.3 Profiles
time of writing.
Table 14 Maximum Transfer Rates of the ADSL Ports
STANDARD MAXIMUM DOWNSTREAM MAXIMUM UPSTREAM
G.dmt 8160 Kbps 1024 Kbps
ANSI T1.413 issue 2 8160 Kbps 1024 Kbps
G.lite 1536 Kbps 512 Kbps
ADSL2 12000 Kbps 1200 Kbps
ADSL2+ 24000 Kbps 1200 Kbps
Downstream refers to traffic going out from the MSAP2000 AAM to the
subscriber's ADSL modem or router. Upstream refers to traffic coming into the
MSAP2000 AAM from the subscriber's ADSL modem or router.
A profile is a table that contains a list of pre-configured ADSL settings. Each
ADSL port has one (and only one) profile assigned to it at any given time. The
profile defines the latency mode and upstream/downstream latency delay,
maximum and minimum upstream/ downstream rates, the target
upstream/downstream signal noise margins, and the maximum and minimum
upstream/downstream acceptable noise margins of all the ADSL ports that have
this profile. You can configure multiple profiles, including profiles for
troubleshooting.
Profiles allow you to configure ADSL ports efficiently. You can configure all of the
ADSL ports with the same profile, thus removing the need to configure the ADSL
ports one-by-one. You can also change an individual ADSL port by assigning it a
different profile.
57
C HAPTER 7
MSAP2000 AAM User’s Guide
For example, you could set up different profiles for different kinds of accounts (for
example, economy, standard and premium). Assign the appropriate profile to an
ADSL port and it takes care of a large part of the port's configuration maximum
and minimum transfer rates. You still get to individually enable or disable each
port, as well as configure its channels and operational mode. See later in this
chapter for how to configure profiles.
7.4 Interleave Delay
Interleave delay is the wait (in milliseconds) that determines the size of a single
block of data to be interleaved (assembled) and then transmitted. Interleave delay
is used when transmission error correction (Reed- Solomon) is necessary due to a
less than ideal telephone line. The bigger the delay, the bigger the data block size,
allowing better error correction to be performed.
Reed-Solomon codes are block-based error correcting codes with a wide range of
applications. The Reed-Solomon encoder takes a block of digital data and adds
extra "redundant" bits. The Reed-Solomon decoder processes each block and
attempts to correct errors and recover the original data.
7.4.1 Fast Mode
Fast mode means no interleaving takes place and transmission is faster (a "fast
channel"). This would be suitable if you have a good line where little error
correction is necessary.
7.5 Configured Versus Actual Rate
You configure the maximum rate of an individual ADSL port by modifying its
profile or assigning a different profile to the port. However, due to noise and other
factors on the line, the actual rate may not reach the maximum that you specify.
Even though you can specify arbitrary numbers for a profile, the actual rate is
always a multiple of 32 Kbps. If you enter a rate that is not a multiple of 32 Kbps,
the actual rate will be the next lower multiple of 32Kbps. For instance, if you
specify 60 Kbps for a port, the actual rate for that port will not exceed 32 Kbps,
and if you specify 66 Kbps, the actual rate will not be over 64Kbps.
Regardless of a profile's configured upstream and downstream rates, the
MSAP2000 AAM automatically limits the actual rates for each individual port to
the maximum speeds supported by the port's ADSL operational mode. For
example, if you configure a profile with a maximum downstream rate of 25000
Kbps, and apply it to a port set to use G.dmt, the MSAP2000 AAM automatically
uses a maximum downstream rate of 8160 Kbps. This means that if you
configure a profile with very high rates, you can still use it with any port. See Table
14 on page 83 for a list of the maximum rates supported by the different ADSL
standards.
58
MSAP2000 AAM User’s Guide
7.6 Default Settings
The default profile always exists and all of the ADSL ports use the default profile
settings when the MSAP2000 AAM is shipped. The default profile's name is set
to DEFVAL. The default profile's maximum downstream rate can only be obtained
when using the G.dmt standard. Configure a profile with a maximum downstream
rate of 1536 Kbps or less for use with G.lite.
Refer to the chapter on initial configuration for the settings of the default profile and
ADSL port default settings.

7.8 Virtual Channels
Defining virtual channels (also called Permanent Virtual Circuits or PVCs) allows
you to set priorities for different services or subscribers. You can define up to eight
channels on each DSL port and use them for different services or levels of service.
You set the PVID that is assigned to untagged frames received on each channel.
You also set an IEEE 802.1p priority for each of the PVIDs. In this way you can
assign different priorities to different channels (and consequently the services that
get carried on them or the subscribers that use them).
62
MSAP2000 AAM User’s Guide
For example, you want to give high priority to voice service on one of the ADSL
ports.
First configure a static VLAN on the MSAP2000 AAM for voice on the port.
Then do the following:
• Configure a channel on the port for voice service.
• Set the channel to use the PVID of the static VLAN you configured.
• Assign the channel a high priority.
7.8.1 Super Channel
The MSAP2000 AAM forwards frames belonging to VLAN groups that are not
assigned to specific channels to the super channel. Enable the super channel
option to allow a channel forward frames belonging to multiple VLAN groups
(that are not assigned to other channels). The super channel functions in the
same way as the channel in a single channel environment. One port can have
only one super channel.
7.8.2 LLC
LLC is a type of encapsulation where one VC (Virtual Circuit) carries multiple
protocols with each packet header containing protocol identifying information.
Despite the extra bandwidth and processing overhead, this method may be
advantageous if it is not practical to have a separate VC for each carried protocol,
for example, if charging heavily depends on the number of simultaneous VCs.
7.8.3 VC Mux
VC Mux is a type of encapsulation where, by prior mutual agreement, each
protocol is assigned to a specific virtual circuit, for example, VC1 carries IP, VC2
carries IPX, and so on. VC-based multiplexing may be dominant in environments
where dynamic creation of large numbers of ATM VCs is fast and economical.
7.8.4 Virtual Channel Profile
Virtual channel profiles allow you to configure the virtual channels efficiently. You
can configure all of the virtual channels with the same profile, thus removing the
need to configure the virtual channels one-by-one. You can also change an
individual virtual channel by assigning it a different profile.
The MSAP2000 AAM provides two default virtual channel profiles: DEFVAL (for
LLC encapsulation) and DEFVAL_VC (for VC encapsulation). By default, all
virtual channels are associated to DEFVAL.

7.11 ATM QoS
ATM Quality of Service (QoS) mechanisms provide the best service on a per-flow
guarantee. ATM network infrastructure was designed to provide QoS. It uses fixed
cell sizes and built-in traffic management (see the following section on traffic
shaping). This allows you to fine-tune the levels of services on the priority of the
traffic flow.
7.12 Traffic Shaping
Traffic shaping is an agreement between the carrier and the subscriber to regulate
the average rate and fluctuations of data transmission over an ATM network. This
agreement helps eliminate congestion, which is important for transmission of real
7.12.1 ATM Traffic Classes
7.12.1.1 Constant Bit Rate (CBR)
7.12.1.2 Variable Bit Rate (VBR)
time data such as audio and video connections.
These are the basic ATM traffic classes defined by the ATM Forum Traffic
Management 4.0
Specification.
Constant Bit Rate (CBR) is an ATM traffic class that provides fixed bandwidth. CBR
traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for
connections that continuously require a specific amount of bandwidth. Examples
of connections that need CBR would be high-resolution video and voice.
The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections.
Connections that use the Variable Bit Rate (VBR) traffic class can be grouped
into real time (rt-VBR) or non-real time (nrt-VBR) connections.
The rt-VBR (real-time Variable Bit Rate) type is used with bursty connections
that require closely controlled delay and delay variation. An example of an rtVBR connection would be video conferencing. Video conferencing requires realtime data transfers and the bandwidth requirement varies in proportion to the
video image's changing dynamics.
The nrt-VBR (non real-time Variable Bit Rate) type is used with bursty
connections that do not require closely controlled delay and delay variation. An
example of an nrt-VBR connection would be non-time sensitive data file
transfers.
70
MSAP2000 AAM User’s Guide
7.12.1.3 Unspecified Bit Rate (UBR)
The Unspecified Bit Rate (UBR) ATM traffic class is similar to the ABR traffic class
for bursty data transfers. However, while ABR gives subscribers a set amount of
bandwidth, UBR doesn't guarantee any bandwidth and only delivers traffic when
the network has spare bandwidth.
7.12.2 Traffic Parameters
These are the parameters that control the flow of ATM traffic.
7.12.2.1 Peak Cell Rate (PCR)
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells.
This parameter may be lower (but not higher) than the maximum line speed. 1
ATM cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a
maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is
dependent on the line speed.
7.12.2.2 Sustained Cell Rate (SCR)
Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It
specifies the maximum average rate at which cells can be sent over the virtual
connection. SCR may not be greater than the PCR.
7.12.2.3 Maximum Burst Size (MBS)
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at
the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages
to the SCR again. At this time, more cells (up to the MBS) can be sent at the
PCR again.
The following figure illustrates the relationship between PCR, SCR and MBS.
Figure 32 PCR, SCR and MBS in Traffic Shaping
71
MSAP2000 AAM User’s Guide
7.12.2.4 Cell Delay Variation Tolerance (CDVT)
Cell Delay Variation Tolerance (CDVT) is the accepted tolerance of the difference
between a cell's transfer delay and the expected transfer delay. CDVT controls
the time scale over which the PCR is enforced. CDVT is used to determine if a
cell arrived too early in relation to PCR.
7.12.2.5 Burst Tolerance (BT)
Burst Tolerance (BT) is the maximum number of cells that the port is guaranteed
to handle without any discards. BT controls the time scale over which the SCR is
enforced. BT is used to determine if a cell arrived too early in relation to SCR. Use
this formula to calculate BT: (MBS
- 1) x (1 / SCR - 1 / PCR) = BT.
7.12.2.6 Theoretical Arrival Time (T AT)
The Theoretical Arrival Time (TAT) is when the next cell (in an ATM connection's
stream of cells) is expected to arrive. TAT is calculated based on the PCR or
SCR.
The following figure illustrates the relationship between TAT, CDVT and BT. If a
cell arrives at time A, then according to PCR or SCR, the next cell is expected to
arrive at time B. If the next cell arrives earlier than time C, it is discarded or
tagged for not complying with the TAT. Time C is calculated based on the CDVT
or BT.

This chapter shows you how to configure 802.1Q tagged VLANs.
8.1 Introduction to VLANs
A VLAN (Virtual Local Area Network) allows a physical network to be
partitioned into multiple logical networks. Devices on a logical network belong
to one group. A device can belong to more than one group. With VLAN, a
device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and
security among the subscribers. When properly configured, VLAN prevents one
subscriber from accessing the network resources of another on the same LAN,
thus a user will not see the printers and hard disks of another user in the same
building. If you have enabled port isolation in the Switch Setup screen, you do
not need to configure the VLAN to isolate subscribers.
VLAN also increases network performance by limiting broadcasts to a smaller
and more manageable logical broadcast domain. In traditional switched
environments, all broadcast packets go to each and every individual port. With
VLAN, all broadcasts are confined to a specific broadcast domain.
Note that a VLAN is unidirectional; it only governs outgoing traffic.
8.2 Introduction to 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 switch
on which they were created. The VLANs can be created statically by hand or
dynamically through GVRP. The VLAN ID associates a frame with a specific VLAN
and provides the information that switches need to process the frame across the
network. A tagged frame is four bytes longer than an untagged frame and
contains two bytes of TPID (Tag Protocol Identifier, residing within the type/length
field of the Ethernet frame) and two bytes of TCI (Tag Control Information, starts
after the source address field of the Ethernet frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for
Ethernet switches. If a frame received at an Ethernet port has a CFI set to 1, then
that frame should not be forwarded as it is to an untagged port. The remaining
twelve bits define the VLAN ID, giving a possible maximum number of 4,096 (212)
VLANs. Note that user priority and VLAN ID are independent of each other. A
frame with VID (VLAN Identifier) of null (0) is called a
VLAN
84
MSAP2000 AAM User’s Guide
priority frame, meaning that only the priority level is significant and the default
VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs,
a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved, so
the maximum possible VLAN configurations are 4,094.
TPID
2 Bytes
User Priority
3 Bits
CFI
1 Bits
The MSAP2000 AAM handles up to 4094 VLANs (VIDs 1-4094). The switch
accepts incoming frames with VIDs 1-4094.
8.2.1 Forwarding Tagged and Untagged Frames
Each port on the switch is capable of passing tagged or untagged frames. To
forward a frame from an 802.1Q VLAN-aware switch to an 802.1Q VLANunaware switch, the switch first decides where to forward the frame and then
strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-unaware
switch to an 802.1Q VLAN-aware switch, the switch 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.
The egress (outgoing) port(s) of a frame is determined on the combination of the
destination MAC address and the VID of the frame. For a unicast frame, the
egress port based by the destination address must be a member of the VID, also;
otherwise, the frame is blocked. For a broadcast frame, it is duplicated only on
ports (except the ingress port itself) that are members of the VID, thus confining
the broadcast to a specific domain.
Whether to tag an outgoing frame depends on the setting of the egress port on
an individual VLAN and port basis (remember 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.
8.3 Automatic VLAN Registration
GARP and GVRP are the protocols used to automatically register VLAN
8.3.1 GARP
membership across switches.
GARP (Generic Attribute Registration Protocol) allows network switches to
register and de- register attribute values with other GARP participants within a
bridged LAN. GARP is a protocol that provides a generic mechanism for
protocols that serve a more specific application, for example, GVRP.

MSAP2000 AAM User’s Guide
8.3.1.1 GARP Timers
Switches join VLANs by making a declaration. A declaration is made by issuing a
Join message using GARP. Declarations are withdrawn by issuing a Leave
message. A Leave All message terminates all registrations. GARP timers set
declaration timeout values.
8.3.2 GVRP
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a
way for switches to register necessary VLAN members on ports across the network.
Enable this function to permit VLANs groups beyond the local switch.

This chapter describes the IGMP Snooping screen.
9.1 IGMP Snooping
IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to
establish membership in a multicast group - it is not used to carry user data.
Refer to RFC 1112 and RFC 2236 for information on IGMP versions 1 and 2
respectively.
A switch can passively snoop on IGMP Query, Report and Leave (IGMP version 2)
packets transferred between IP multicast routers/switches and IP multicast hosts
to learn the IP multicast group membership. It checks IGMP packets passing
through it, picks out the group registration information, and configures
multicasting accordingly. IGMP snooping allows the switch to learn multicast
groups without you having to manually configure them.
The switch forwards multicast traffic destined for multicast groups (that it has
learned from IGMP snooping or that you have manually configured) to ports that
are members of that group. The switch discards multicast traffic destined for
multicast groups that it does not know. IGMP snooping generates no additional
network traffic, allowing you to significantly reduce multicast traffic passing
through your switch.

which means that past addresses are “recycled” and made available for future
reassignment to other systems.

Spanning Tree
Protocol
This chapter introduces the Rapid Spanning Tree Protocol (RSTP).
13.1 RSTP (Rapid Spanning Tree Protocol) and STP
(Spanning Tree Protocol)
RSTP adds rapid reconfiguration capability to STP. The switch supports RSTP
and the earlier STP. RSTP and STP detect and break network loops and provide
backup links between switches, bridges or routers. They allow a device to
interact with other RSTP or STP-aware devices in your network to ensure that
only one path exists between any two stations on the network. The switch uses
RSTP by default but can still interoperate with STP switches
(although without RSTP's benefits).
The root bridge is the base of the spanning tree; it is the bridge with the lowest
identifier value
(MAC address). Path cost is the cost of transmitting a frame onto a LAN through
that port. It is assigned according to the speed of the link to which a port is
attached. The slower the media, the higher the cost - see the following table.
Table 33 STP Path Costs
LINK SPEED RECOMMENDED VALUE RECOMMENDED RANGE ALLOWED
RANGE
Path Cost 4Mbps 250 100 to 1000 1 to 65535
Path Cost 10Mbps 100 50 to 600 1 to 65535
Path Cost 16Mbps 62 40 to 400 1 to 65535
Path Cost 100Mbps 19 10 to 60 1 to 65535
Path Cost 1Gbps 4 3 to 10 1 to 65535
Path Cost 10Gbps 2 1 to 5 1 to 65535
On each bridge, the root port is the port through which this bridge communicates
with the root. It is the port on this switch with the lowest path cost to the root (the
root path cost). If there is no root port, then this switch has been accepted as the
root bridge of the spanning tree network.
For each LAN segment, a designated bridge is selected. This bridge has the
lowest cost to the root among the bridges connected to the LAN.
