1.1 Product Positioning

CAUTION

AR G3 Series Enterprise Routers are class A products. Customers should take preventative

measures as the operating devices may cause radio interference.

AR series enterprise routers (ARs) include AR150, AR200, AR1200, AR2200, and AR3200.

They are the next-generation routing and gateway devices, which provide the routing, switching,

wireless, voice, and security functions.

As shown in Figure 1-1, the ARs are located between an enterprise network and a public

network, functioning as the only ingress and egress for data transmitted between the two

networks. The deployment of various network services over the ARs reduces operation &

maintenance (O&M) costs as well as those associated with establishing an enterprise network.

You can select ARs of different specifications as egress gateways based on the user quantity of

an enterprise.

The ARs provide the most economical enterprise network solutions.

The ARs support flexible slot combination. For example, two SIC slots can be combined into a

wide SIC (WSIC) slot, two WSIC slots are combined into an extra SIC (XSIC) slot, and two

XSIC slots can be combined into an extended extra SIC (EXSIC) slot. In addition, a SIC card

can be installed into a WSIC slot.

NOTE

AR150&200 series do not support subcards.

1.2.4 Remote Maintenance Capability

In addition to one-stop deployment, plug and play capability, and remote commissioning

2.1 WAN Access

Depending on the network environment provided by carriers, users can access the network by

using CE1/CT1, E1/T1-F, 3G, FE/GE, ADSL, VDSL, G.SHDSL, Integrated Services Digital

Network (ISDN), CPOS, AS, xPON or SA. The ARs provide dual-uplink to ensure service

reliability. The ARs provide the following services for access users:

As shown in Figure 2-1, enterprise A accesses the Internet using ADSL; enterprise B accesses

the Internet using FE and CE1 dual-uplink; enterprise C accesses the Internet using G.SHDSL;

enterprise D accesses the Internet using 3G.

2.2 VPN Access

The headquarters and branches use the ARs establish a VPN and connect to the Internet. The

enterprise establishes a VPN and uses GRE, MPLS, or IPSec VPN to ensure data security. The

employees on a business trip use IPSec VPN tunnels to communicate with the headquarters.

As shown in Figure 2-2, the headquarters is connected to the Internet by using the

AR2200&3200, and provides services for all employees. The LAN of the branch connects to

Huawei AR G3 Series Enterprise Routers

Product Description 2 Network Applications

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

the Internet by using the AR150&200&1200&2200, so the employees in the branch can access

the headquarters network.

The headquarters and branch use GRE VPN, MPLS/BGP IP VPNor IPSec VPN tunnels to

establish an intranet. The employees on a business trip set up IPSec VPN , L2TP VPN or SSL

VPN tunnels, and access the intranet after passing authentication.

2.3 Enterprise Intranet Security

The ARs, located between the enterprise intranet and the Internet, ensure information security

on the entire intranet and intranet LANs.

As shown in Figure 2-3, an intranet and the Internet are connected by the ARs. The users on

the Internet cannot access the intranet. To allow the users on the intranet to access the Internet,

configure network address translation (NAT) on the intranet. The financial department and

marketing department have individual LANs on the intranet. The ARs utilize a demilitarized

zone to protect the server on the external network. In addition, the application specific packet

filter (ASPF) firewall can be deployed to protect the intranet.

The ARs provide network access control (NAC) to restrict the access permissions of internal

users. This ensures that only authorized users can access the intranet.

2.4 Voice Application

NOTE

lAmong the AR200 series routers, only the AR207Vs and AR207V-Ps support the voice features.

Among the AR1200 series routers, only the AR1220Vs and AR1220VWs support the voice features.

The AR2200 and AR3200 series routers support the voice features only after a DSP module is installed.

lTo provide voice services for POTS users on AR1200, AR2200 ,and AR3200 series routers, 4FXS/

1FXO board is required.

lTo provide voice services for ISDN users on AR1200, AR2200 ,and AR3200 series routers, 2BST

board is required.

An enterprise can build a voice communication system over the IP network, reducing operating

expenses (OPEX).

Within the voice communication system, an AR can function as an IP PBX or SIP access gateway

(AG). The AR connects to POTS users (analog phones or fax machines) and SIP user equipment

(UE) users (IP phones or PC software terminals) through FXS or Ethernet interfaces. The AR

connects to the PSTN through FXO interfaces or to the IP network through Ethernet interfaces.

Based on branch locations, the centralized or distributed call control model can be used. If all

branches within an enterprise use the same number segment, the centralized call control model

is recommended. If an enterprise has many branches that use different number segments, the

distributed call control model is recommended.

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

As shown in Figure 2-4, the enterprise headquarters and branch A use different number

segments. The ARs working in IP PBX mode are deployed at the enterprise headquarters and

branch A as egress routers. Voice users in the enterprise headquarters are registered with the AR

in the enterprise headquarters, and voice users in each branch are registered with the AR in the

branch. Voice traffic is transmitted between the enterprise headquarters and branches over voice

routes. The AR of the enterprise headquarters provides voice routes to branches so that users in

different branches can call each other.

Branch B and the enterprise headquarters are connected through the MAN. An AR working in

IP PBX mode is deployed at the enterprise headquarters and an AR working in SIP AG mode

is deployed at branch B. All voice users at the enterprise headquarters and branches are registered

with the AR at the enterprise headquarters. The AR in the enterprise headquarters provides call

PBX

PBXs are widely used in enterprises. They manage incoming and outgoing calls of enterprises.

The AR as a PBX supports the following individual and group services.

Table 3-3 Individual Service supported by a PBX

Service Type Description

Abbreviated dialing Allows a user to dial an abbreviated code of

one or two digits instead of the original called

number.

Outgoing call barring Restricts call-out permissions of some

phones. For example, the outgoing call

barring service can prevent a phone from

making long-distance calls.

Call forwarding Allows a called user to transfer a call to a

specified third party if the called user has

activated the call forwarding service and the

call meets the call forwarding conditions.

Number barring Prevents a user from dialing a specified

number.

Do-not-disturb Rejects calls to a user. When other users call

a user that has subscribed to the do-not-

disturb service, they hear a do-not-disturb

tone or busy tone.

Reject anonymous call Allows a user to reject a call when the calling

number is not displayed and plays a voice

prompt to the calling user.

Remote office Allows a user to access the office telephone

network from any terminal and use original

services such as abbreviated dialing and call

transfer.

Secretary Allows a user to designate another phone

number (for example, the secretary's phone

number) to process all incoming calls. That

is, all incoming calls of the user are

transferred to the secretary's phone number

first, and only the secretary can call the user

directly.

Wake-up service Allows a phone to ring automatically at the

preset time.

Personal ring back tone (RBT) Uses user-defined music or sound effects to

replace the common ringback tone, and plays

the music or sound effects to calling users.

For details about voice features, see Feature Description - Voice.

3.2.2 WAN

WAN uses the interfaces such as Ethernet, E1, T1, ADSL, VDSL, G.SHDSL, CPOS, 3G, and

synchronous/asynchronous serial interfaces. The physical links on these interfaces can run the

FR, PPP, and HDLC protocols.

Frame Relay

Working at the data link layer of the Open System Interconnection (OSI) model, Frame Relay

(FR) uses simple methods to transmit and exchange data. On a frame relay (FR) network, virtual

circuits connect two FR devices. A physical line on the FR network provides multiple VCs. A

VC defines an FR channel by using the data link connection identifier (DLCI), and detects and

maintains the VC status by using the local management interface (LMI).

Multilink frame relay (MFR) is a cost-effective solution provided for FR users. MFR (FRF.16)

implements the multilink frame relay function on the user-to-network interfaces (UNIs).

The FR compression technologies compress FR packets to save network bandwidth, reduce

network load, and improve data forwarding on the FR network. The AR supports FRF.9 (FRF.

9 stac) and FRF.20 (FRF.20 IPHC).

PPP

The point-to-point protocol (PPP) is used at the data link layer of the OSI model as well as at

the link layer of TCP/IP. PPP transmits data from one point to another through synchronous

links and asynchronous links that support full duplex.

Huawei AR G3 Series Enterprise Routers

Product Description 3 Product Characteristics

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

PPP provides a complete authentication mechanism. To set up a PPP connection, users must

pass authentication, ensuring a secured connection.

Multilink PPP (MP) is a technique that bundles multiple PPP links together to increase

bandwidth. It can be applied to the interfaces that support PPP, such as serial interfaces and low-

speed Packet over SDH (POS) interfaces.

PPPoE

A Point-to-Point Protocol over Ethernet (PPPoE) network consists of an Ethernet containing

many hosts. It accesses the Internet through a remote access device.

An AR can create a PPP session with the remote end by using PPPoE, and implement access

control and accounting.

An AR can function as the PPPoE server to connect to different types of PPPoE clients on the

Ethernet or function as a dial-up PPPoE client.

ATM

ATM is connection-oriented. Each VC is identified by a Virtual Path Identifier (VPI) and a

Virtual Channel Identifier (VCI). One pair of VPI/VCI values is useful only on a link segment

between ATM nodes. If a connection is broken, the relevant VPI/VCI values are released.

The Asymmetric Digital Subscriber Line (ADSL) , VDSL and G.Single-pair High Speed Digital

Subscriber Line (G.SHDSL) interfaces of the ARs support the Asynchronous Transfer Mode

(ATM).

HDLC

The High-level Data Link Control (HDLC) is a typical bit-oriented synchronization data control

protocol. It adopts the full-duplex mode and CRC check. Its transmission control function is

independent of the processing function, and it features control capabilities and can be flexibly

used.

In HDLC, Keepalive packets are used to detect the link status. On the AR, you can set the interval

for sending Keepalive packets by setting the polling interval.

ISDN

The ISDN protocol references the Open Systems Interconnection (OSI) model and implements

functions of the physical layer, data link layer, and network layer on UNI interfaces.

ISDN physical interfaces are classified into ISDN BRI and ISDN PRI interfaces.When the AR

accesses an ISDN network by using an ISDN PRI interface, the AR is directly connected to an

ISDN network-side device. When the AR accesses an ISDN network by using an ISDN BRI

interface, the AR connects to an NT1 device, and the NT1 device connects to an ISDN network-

side device.

For details about WAN features, see Feature Description - WAN.

3.2.3 VPN

The ARs provide an IP security (IPSec) mechanism to ensure high quality, interoperable, and

cryptology-based security for communication processes. The two parties in communication can

Huawei AR G3 Series Enterprise Routers

Product Description 3 Product Characteristics

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

encrypt data and authenticate the data source at the IP layer to ensure the confidentiality and

integrity of the data and prevent replay on the network.

IPSec implements these functions by using two security protocols: Authentication Header (AH)

protocol and Encapsulating Security Payload (ESP). Internet Key Exchange (IKE) provides the

automatic key negotiation, SA establishment, and SA maintenance functions to simplify IPSec

use and management.

The AR supports IPSec VPN and provides high reliability transmission tunnels for users. In

addition, the AR uses Generic Routing Encapsulation (GRE) and Layer 2 Tunneling Protocol

(L2TP) to support the following VPN services:

lGRE VPN

lIPSec VPN

lBGP/MPLS IP VPN

lSSL VPN

lL2TP VPN

lDSVPN

lGRE over IPSec VPN

lL2TP VPN over IPSec VPN

For details about VPN features, see Feature Description - VPN.

3.2.4 Security

ACL

An access control list (ACL) defines a series of filtering rules based on certain policy, the ACL

permits or forbids the passage of data packets.

The ARs can use ACL rules to filter packets.

Firewall

lACL-based packet filtering

ACL-based packet filtering is used to analyze the information of the packets to be

forwarded, including source/destination IP addresses, source/destination port numbers, and

IP protocol numbers. The ARs compare the packet information with the ACL rules and

determine whether to forward or discard the packets.

In addition, the ARs can filter the fragmented IP packets to prevent the non-initial fragment

attack.

lASPF

Application Specific Packet Filter (ASPF) filters packets of the application layer based on

packet status. ASPF, used for security policies, detects the session information of the

application layer protocol packets, which attempt to pass the AR and prevent the unsatisfied

packets.

lAttack defense

With the attack defense feature, the ARs can detect various network attacks and protect the

internal network against attacks.

Network attacks are classified into three types: DoS attacks, scanning and snooping attacks,

and malformed packet attacks.

Huawei AR G3 Series Enterprise Routers

Product Description 3 Product Characteristics

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

–DoS attack

The DoS attack is an attack to a system by using a large number of data packets. This

prevents the system from receiving requests from authorized users or suspends the host.

DoS attacks include SYN Flood attacks and Fraggle attacks. DoS attacks are different

from other attacks because DoS attackers do not search for the ingress of a network, but

prevent authorized users from accessing resources or routers.

–Scanning and snooping attack

The scanning and snooping attack is to identify the existing systems on a network by

using ping scanning (including ICMP and TCP scanning), and then find out potential

targets. By using TCP scanning, attackers can identify the operating system and the

monitored services. By scanning and snooping, an attacker can know the service type

and security vulnerability of the system and prepare for further intrusion to the system.

–Malformed packet attack

The malformed packet attack is to send malformed packets to the system. If such an

attack occurs, the system breaks down when processing the malformed IP packets.

Malformed packet attacks include Ping of Death and Teardrop.

ARP Security

There are various ARP attacks on networks, including attacks targeting hosts and gateways,

address spoofing attacks and violent attacks, virus attacks, and malicious software attacks.

The ARs ensure ARP security by discarding untrusted ARP packets, suppressing ARP packets

by using timestamps, discarding invalid ARP packets, and performing dynamic CAR on the

packets sent to the CPU. In addition to preventing ARP protocol attacks, the ARs also prevent

ARP-based network scanning attacks.

IP Source Guard

Some attacks on networks aim at source IP addresses by accessing and using network resources

through spoofing IP addresses, stealing users' information or blocking authorized users from

accessing networks.

lThe AR2200 and AR3200 series routers support IP source guard. IPSG prevents source

address spoof attacks, so attackers cannot access network resources and authorized users'

rights are protected.

lUnicast Reverse Path Forwarding (URPF) blocks packets sent from bogus source

addresses.

Local Attack Defense

The Internet technology and size develop quickly and various network applications emerge.

Many enterprises try to boost their own development by using their networks. They are

concerned about how to protect confidential data and resources in an open network environment.

Some unconscious operations may attack network devices and degrade device performance or

even cause device failure.

A large number of packets including valid packets and malicious attack packets on a network

must be processed by devices' CPUs. The malicious attack packets affect services and may even

cause a system breakdown. In addition, excessive normal packets can also lead to high CPU

usage, which degrades the CPUs' performance and interrupts services. Therefore, protecting the

CPU is a necessary and important factor for processing services and system response.

Huawei AR G3 Series Enterprise Routers

Product Description 3 Product Characteristics

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

The local attack defense and source tracing functions protect the ARs against attacks. When an

attack occurs, these functions ensure non-stop service transmission and minimize the impact of

the attack on network services.

PKI

The public key infrastructure (PKI) is a system that generates public keys and digital certificates,

and verifies identities of certificate subjects to ensure information security. PKI issues digital

certificates that bind public keys to respective user identities by means of a certificate authority

(CA).

AAA

The ARs support Authentication, Authorization, and Accounting (AAA).

lAuthentication

Verifies users' identities.

lAuthorization

Grants different rights for different users to restrict the services that can be used by users.

lAccounting

Records information about network service usage of users, including service type, start

time, and traffic volume.

For details about security features, see Feature Description - Security.

3.2.5 QoS

Traffic Policing

Traffic policing discards excess traffic to limit the traffic within a specified range and to protect

network resources as well as the carriers' interests.

The ARs use committed access rate (CAR) to perform traffic policing. They support dual-rate-

three-color markers and precise bandwidth management.

Traffic Shaping

When the rate of an interface on a downstream device is slower than that of an interface on an

upstream device or burst traffic occurs, traffic congestion may occur on the downstream device

interface. Traffic shaping can be configured on the interface of an upstream device so that

outgoing traffic is sent at even rates and congestion is avoided.

The AR supportstraffic shaping adaptation and level-3 traffic shaping. Three-level shapers

include the flow queue shaper, subscriber queue shaper, and port queue shaper.

Congestion Management

If a network transmitting both delay-sensitive and delay-insensitive services is congested

intermittently, congestion management is required. However, if a network is always congested,

bandwidth needs to be increased. Congestion management sends packet flows by using queuing

and scheduling.

An interface on AR has four or eight default queues for outgoing packets. A fixed FE interface

on AR1220 has four default queues and each of other interfaces has eight. LAN-side interfaces

Huawei AR G3 Series Enterprise Routers

Product Description 3 Product Characteristics

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

support the scheduling modes of priority queuing (PQ), deficit round robin (DRR), weighted

round robin (WRR), PQ+DRR, and PQ+WRR. The AR150&200&1200 series routers do not

support the DRR mode. WAN-side interfaces support the scheduling modes of PQ, WFQ, PQ

+WFQ, and class-based WFQ (CBQ). Each scheduling algorithm schedules specific types of

traffic, and affects bandwidth allocation, delay, and jitter.

Congestion Avoidance

Congestion avoidance is a flow control mechanism. A system configured with congestion

avoidance monitors network resource usage such as queues and memory buffers. When

congestion occurs or aggravates, the system discards packets.

The ARs support tail drop and WRED.

lTail drop

When the queue length reaches the upper limit, the excess packets (buffered at the queue

tail) are discarded.

lWRED

WRED sets the upper and lower drop thresholds and the maximum drop probability for

each queue. When the queue length is smaller than the lower threshold, no packets are

discarded. When the length of the queue exceeds the upper threshold, all packets are

discarded. When the queue length is between the lower threshold and the upper threshold,

incoming packets are discarded randomly. The drop probability cannot be greater than the

maximum drop probability.

The ARs use the WRED based on queue profiles or traffic policies.

For details about QoS features, see Feature Description - QoS.

3.2.6 WLAN

NOTE

Only AR1220W and AR1220VW support WLAN.

A wireless local area network (WLAN) connects two or more computers or devices and enables

the devices to communicate by using the wireless telecommunication technology. WLAN uses

the wireless technology to implement fast Ethernet access. The primary advantage of WLAN is

that terminals, such as computers, can access a network through a wireless medium rather than

a physical cable. This facilitates network construction and allows users to move around without

interrupting communication. WLAN is more flexible than traditional wired access.

WLAN is widely used in public areas such as on campuses, business centers, and airports. The

WLAN uses cables at the backbone layer, and users access the WLAN through one or more

wireless access points (WAPs) using radio waves. The transmission distance of a WAP is tens

of meters.

IEEE 802.11 is widely used by WLANs. The AR functions as fat APs to provide the following

WLAN functions:

lWLAN user management

–Dot1X access authentication

–MAC address authentication

–Pre-share-key (PSK) authentication

6 Maintenance and Management

About This Chapter

6.1 Various Maintenance Methods

6.2 Fault Location

Huawei AR G3 Series Enterprise Routers

Product Description 6 Maintenance and Management

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

6.1 Various Maintenance Methods

The ARs support various local and remote maintenance methods:

lLocal maintenance using the console interface

lLocal or remote maintenance using Telnet

lSecure shell (SSH) maintenance: guarantees security and provides authentication for login

users on an insecure network, and defends against various attacks, including IP address

spoofing, plain text password interception, and denial of service (DoS).

6.1.1 Web-based Network Management System

The ARs support the web-based network management system, which provides GUI for device

configuration and management.

Users can use the web-based system to manage network devices on the GUI. A junior engineer

can use the GUI easily.

6.1.2 CWMP

The CPE WAN Management Protocol (CWMP) is drafted by the Digital Subscriber's Line (DSL)

forum. It is also called TR-069 standard. CWMP standardizes the communication between

customer premises equipment (CPE) and auto-configuration server (ACS).

There are a lot of user devices separated on the access network. They are difficult to manage

and maintain. The ARs are the CPE deployed at the user network side. The ACS uses CWMP

to remotely manage the CPE. This reduces maintenance cost and improves troubleshooting

efficiency.

6.1.3 Remote Deployment and Maintenance Using USB

As the network expands, more and more network devices are used and software commissioning

costs increase. USB-based deployment does not require software commissioning, which reduces

deployment costs.

Before using a USB flash drive to configure an AR, store software package and configuration

files on the USB flash drive. Software engineers do not need to commission devices onsite. After

installing the AR, hardware engineers will insert the USB flash drive into the USB interface on

the AR and power on the AR. After being started, the AR automatically loads and upgrades the

software.

6.1.4 SNMP-based Maintenance

The ARs support the Simple Network Management Protocol (SNMP) v1/v2c/v3 and the Client/

Server model. The ARs can be managed by the network management system (NMS), such as

iManager U2000.

6.2 Fault Location

Huawei AR G3 Series Enterprise Routers

Product Description 6 Maintenance and Management

Issue 02 (2012-04-20) Huawei Proprietary and Confidential

6.2.1 Device Fault Location

The ARs support the following functions to locate device faults:

lLog

After detecting a service error or recovery event, the AR logs the event and sends the

information to the background server.

lFast information collection

A system administrator can use display diagnostic-information to collect device fault

information.

lDevice monitoring

The AR can monitor all the key indexes and components such as voltage, temperature, fan,

and power supply unit. In addition, the AR can send a trap if an error occurs.

6.2.2 Service Fault Location

The ARs support the following functions to locate service faults:

lLocating Ethernet interface faults

The ARs support interface status display, line tests, and loopback tests on interfaces. The

ARs test packet sending and receiving on interfaces and collect packet statistics, assisting

administrators to locate network faults and Ethernet interface connection faults.

lNetwork-side interface faults

The ARs support WAN interface tests, which collect traffic statistics and event statistics

on WAN interfaces and perform tests such as ATM, OAM, and interface loopback.

lPort mirroring and traffic mirroring

The ARs support packet mirroring on Ethernet interfaces, mirroring of packets from a

network-side interface to a user-side Ethernet interface, and mirroring of protocol packets

sent to the CPU.

lConnection fault

The ARs test connections and display connection status on network-side interfaces, and

collect connection statistics.

lVoice signal fault

The ARs record the entire signal interaction process and test signal online. In addition, the

ARs test the quality of VoIP services and locate dialing and service faults.
