for the P330 Stackable Switching System and G700 Gateway. The X330WAN is part
of Avaya’s Converged Networks Solution that includes IP telephones, data switches
and IP exchanges.
Each X330WAN access router module contains its own powerful onboard CPU and
software, which functions as a dedicated WAN Edge Router.
The X330WAN is designed around the following concepts:
• WAN access
•Routing
•Security
•Convergence
The first of the X330WAN series is the X330W-2DS1 access router module, with 2
E1/T1 interfaces, a single 10/100Base-T Fast Ethernet port, and a serial Console
port.
The primary uses of the X330WAN are the following:
• Branch Office connectivity to Headquarters.
• Small/Medium Business connectivity directly to an ISP (Internet Service
Provider).
Branch Office Connectivity to Headquarters
The X330WAN enables connecting the LAN of branch offices based on the P330
switch to the headquarters office, connecting to the corporate WAN. Each branch
office in this solution would use the Internet services supplied via the headquarters
ISP, or connect directly to the Internet independently.
Installing an X330 WAN Access Router in a a G700 Gateway, provides cost-effective
and space-saving IP Telephony and WAN routing for SMEs.
The G700 and P330 can be stacked together, to provide a comprehensive converged
solution.
Small/Medium Business Connectivity Directly to a Service Provider
The X330WAN access router enables SMEs (Small/Medium Enterprises) to connect
their LAN directly to an ISP using a P330 switch. This solution provides
independence and flexibility to the SMEs in the flow of data and other Internet
services.

Chapter 1 Overview
Functional Concepts
One basis for success in today’s business world is combining resources. The
X330WAN supplies you with combined required access functionality for branch
offices and SMEs. The X330WAN was designed and developed to include all of the
functions necessary for branch offices and SMEs.
The following sections describe the overall concepts that together comprise the
functioning of the X330WAN access router.
For examples of common configurations using the following concepts, refer to
Chapter 4: Common Configurations.
WAN Access
WAN access provides a link for routing packets between their WAN and
Ethernet/LAN interfaces, enabling heavy data transfer. WAN access can connect
branch offices to headquarters, and provide fast access to the Internet and e-mail.
When combined with the Avaya G700 Gateway or to the Avaya DEFINITY VoIP
services are provided.
Routing
The X330WAN access router modules provides routing capabilities in a P330
device. They route packets between their WAN and Ethernet/LAN interfaces.The
X330WAN access router modules’ routing software is based on the routing software
of the Avaya P333R and P333R-LB. It provides support for the major routing
protocols. It also provides a L3/L4 Policy classifier working per Layer 2
interface/direction, controlling access and QoS (tagging and mapping to internal
queuing mechanism). The X330WAN independently controls all traffic flow in the
P330 from the LAN to the WAN.
Security
The X330WAN currently contains the infrastructure for all security functionality
planned for future releases, such as Firewall and VPN. Licenses will be issued for
different security options, when development is completed.
Security currently can be achieved with the X330WAN for the initial release by
connecting the Fast Ethernet port of the X330WAN via an external firewall to a port
on the P330 switch. The X330WAN module is connected to the Internet via it’s
WAN ports.
Convergence
The X330WAN enables a combined data and VoIP solution when used in
conjunction with a VoIP gateway, such as the G700. This is achieved by connecting
the G700 to the LAN’s P330 stack, and inserting the X330WAN in one of the
2 Avaya X330W-2DS1 User’s Guide
expansion slots, either of the P330 stack or of the G700. Standard IP phones can be
connected to the P330 stack, or Avaya Legacy phones can be connected directly to
the G700 Gateway. In this solution the X330WAN provides access to the corporate
WAN, while end-to-end QoS and Policy ensure that the IP telephony functions
flawlessly.
Features
An Avaya P330 stack may have X330WAN access router modules inserted in each
of the switches in the stack with an expansion slot. A maximum stack configuration
of 10 P334T switches using the X330W-2DS1 provides 480 Ethernet 10/100 ports,
and 20 E1/T1 ports. The X330W-2DS1 is the first product of the X330WAN series.
The following is a list of X330W-2DS1 features.
Layer 1 Features
• 2 channelized/fractionalized E1/T1 ports, RJ-48 connectors.
• 10/100Base-T Auto Negotiation Fast Ethernet port.
• 100 Mbps, Full Duplex Fabric Fast Ethernet interface (for internal connection to
• Serial RS-232, RJ-45 port for console and dial-in modem connection.
Features
the P330).
Layer 2 Features
• PPP over channeled and fractional E1/T1. The X330WAN has the ability to map
several PPP sessions to a single E1/T1 interface.
• Support for up to 253 VLANs on the Fabric Fast Ethernet LAN interface. Any
combination of these VLANs can be configured to the X330WAN module.
• Auto-Negotiation - the 10/100 port on the X330WAN supports
Auto-Negotiation which automatically detects and supports the duplex mode
and speed of a connected device. This means that you can simply connect the
X330WAN to Ethernet or Fast Ethernet equipment at full or half duplex without
configuration.
• VLANs - VLANs assigned on the Fabric Fast Ethernet port enable the
X330WAN to perform inter-VLAN routing. This enables the user to configure
specific VLANs to access the X330WAN, while the remaining VLANs are
denied access to the WAN.

Chapter 1 Overview
Layer 3 Features
• Supports RIP v1/v2 routing protocols
• Supports Single Area OSPF routing protocol - the X330WAN can be configured
as an OSPF Autonomous System Boundary Router (ASBR) by configuration of
route redistribution. The X330WAN can be installed in the OSPF backbone area
(area 0.0.0.0) or in any OSPF area that is part of a multiple areas network. The
X330WAN cannot be configured to be an OSPF area border router itself.
• Supports VRRP redundancy protocol - supported only on the X330WAN’s LAN
(Fast Ethernet and Fabric Fast Ethernet) ports.
• Supports Equal-Cost MultiPath (ECMP) - allows load balancing by splitting
traffic between several equivalent paths.
• Supports Distribution Lists - these lists define which routers are trusted
regarding OSPF. Routing information is only allowed to be transmitted to or
received from the trusted routers.
Convergence Features
• Priority queueing - the X330WAN supports the ability to separate traffic into 4
strict priority queues per interface. The assignment of placement in the queues
is performed using Policy.
• Guaranteed delay for VoIP traffic - the X330WAN supports VoIP Queue mode.
In this mode traffic labelled as voice traffic receives preference to all other
traffic. The X330WAN default mode is optimized for the G.729 codec.
• Random Early Detect (RED) - the X330WAN uses RED in order to improve the
performance of the network when overloaded. RED sends signals to
transmitting hosts stating that the bandwidth is limited, and that they should
reduce their transmission speed.
• RTP Header Compression - The Real Time Protocol (RTP) is the basis of
common VoIP traffic. RTP runs over UDP, and incurs a 12-byte header on top of
other (IP, UDP) headers. Running on PPP or Frame-Relay, this protocol can be
compressed.
X330WAN RTP Header Compression process is based on the fact that the
packet order on a PPP link is preserved. As a result, many times only the
“deltas” from the previous packet’s header needs to be sent, and not the full
header. Moreover, since the “deltas” are often constant, the second order
“delta” is 0 and does not need to be transmitted. In many cases, all three
headers (IP+UDP+RTP~40 bytes) can be reduced to a size of 2-4 bytes.
• Fragmentation and Reassembly - the X330WAN supports:
— Fragmentation of IP packets according to RFC 791.
— Reassembly of IP packets destined only to the X330WAN (i.e., packets that
Fragmented IP packets with destinations other than this X330WAN will NOT be
reassembled by this X330WAN.
have its IP address as their destination address).

QoS Features
Features
Reassembly is associated with the following user configurable parameters:
— The number of maximum possible concurrent reassembled packets:
Min=0; Max=200; Default=100.
— The time, in seconds, to wait for a packet to be reassembled:
Min=5; Max=120; Default=10.
— The maximum number of fragments allowed per packet:
Min=2; Max=2048; Default=64.
In addition, it is possible to restore the reassembly parameters to their default
values. This discards all packets currently waiting to be reassembled.
• Access Control and QoS per interface and direction - the X330WAN supports
individual Access Control and QoS lists per interface, and per direction. This
enables the user to configure access and QoS for each direction
(transmit/receive) of each session.
Efficient use of QoS enables the X330WAN to assign the proper priority to different
incoming and outgoing traffic flows to minimize the affect of one flow on the other,
and to prevent a low priority traffic flow from affecting a high priority traffic flow
and the like. To achieve this, the X330WAN implements multiple receiving queues
and configurable transmitting queues (4 queues per interface).
Priority queuing is implemented among the four queues on each interface:
•Voice (highest priority)
• High priority data
•Better than best effort
• Best effort (low priority)
To insure minimal affect of one flow to the other, the following priority order (from
highest to lowest) is always maintained:
• Transmit tasks - highest priority.
• Receive tasks - medium priority.
• Router tasks - lowest priority.
Note: You can adjust the queue length for different needs. Queue length should
always be kept a small as possible, while still maintaining a flow. It is recommended
to always use the default queue length, as this is the optimal calculated length.
Policy
In the X330WAN a policy list contains:
• A set of classification rules based on a source IP, destination IP, source port,
destination port, protocol, and TCP Established bit. The IP addresses can
include wildcards.
Avaya X330W-2DS1 User’s Guide 5
Chapter 1 Overview
• A set of possible actions arranged in a Composite Operations Table.
• A set of DSCP mappings.
Several policy lists can be activated concurrently, with each list applied to a
different interface and direction.
Each Serial interface (PPP session), the Fast Ethernet port, and the
FabricFastEthernet interface can have an ingress and egress active Policy list. For the
FabricFastEthernet interface, this list applies to all L2 interfaces (VLANs) mapped to
this interface.
A default Policy list (list 0) is always present and active until a different Policy list is
activated. The default list has one rule (permit all), a default DSCP mapping, and a
default Composite Operations table.
Whenever a new Policy list is created, it contains a copy of the list 0 components.
Policy rules and the Composite Operations Table include the following actions:
• Access Control actions (for all types of interfaces):
—Drop
— Drop and Notify
—Forwarding
• QoS actions:
— DSCP coloring (value changing) for all types of interfaces.
— Priority tag modifications for:
The Composite Operation Table contains pre-defined entries for the basic policies
that existed in the P333R. These entries are created by the agent for each Access List
and are Read Only.
— Packets that traverse the inband LAN or the Ethernet port. This will be
marked as the IEEE 802.1p tag in the packet (only on the
FabricFastEthernet interface).
— Classification into one of the 4 transmit queues.
Controlling Network Access to the X330WAN
Using Policy lists, you can control all traffic designated to and from the X330WAN’s
CPU, including management and routing protocols traffic. By activating Policy
rules defined for a Loopback interface, you can control all traffic entering/leaving
the CPU from/to all X330WAN interfaces. Rules governing traffic to the CPU can be
defined at a single point, regardless of the actual interface which the packet entered
and the specific IP address being managed.
Note: A Policy list activated on a Loopback interface does not apply to packets
routed by the CPU.

Chapter 1 Overview
Interfaces
The X330WAN includes Physical and Virtual interfaces.
Physical Interfaces
The following are the X330WAN physical interfaces:
• WAN Interfaces – 2 ports, configurable for E1 or T1.
• LAN Interface – FastEthernet interface.
This interface is an autosensing 10/100Mbps Ethernet port. It can be used to
connect to a LAN or to a firewall/VPN.
• P330 Switching Fabric – FabricFastEthernet interface.
This is an internal 100Mbps connection to the P330 switching fabric. It supports
VLANs, and is compatible with the P330.
When connecting the X330WAN in Access-Router Only mode (e.g., no VPN or
firewall), this interface can be used to connect to the hosting P330 switch.
• Console Interface – used to connect a terminal for local management, or a
modem for remote management.
Virtual Interfaces
The following are the X330WAN virtual interfaces:
• Loopback – This interface is a logical interface that is not mapped to any
physical interface. Its purpose is to represent the router with an IP address that
is always reachable. This is mainly used for network troubleshooting. It also
provides a ‘Router ID’ in the OSPF routing protocol.
Since the Loopback Interface is not connected to any physical interface, an entry
in the routing table cannot have the loopback interface’s subnet as its next hop.
Note: The first interface created in the X330WAN should be an IP interface defined
over the Loopback interface.
• VLAN (on the FabricFastEthernet Interface) – The P330 can have multiple
VLANs defined within its switching fabric. To connect to the switching fabric,
the X330WAN supports up to 253 VLANs.
• Serial Link – This is a virtual interface that is created over a portion of an E1 or
a T1.
This interface is used to directly connect the X330WAN to another device at the
other end of a leased line, and supports Encapsulation PPP and Frame Relay
protocols.
