2INTRODUCING THE ROUTER 6000

FAMILY

Introduction 3Com 6000 Routers are next generation, high-performance edge routers. The

Router 6040 is a 4-slot chassis. The Router 6080 is an 8-slot chassis. 3Com 6000

Routers offer a robust hardware design, supporting Flexible Interface Cards (FICs),

hot swappable Power Supply Unit (PSU), and 1+1 power backup. Following are

the main features of 6000 Routers.

Flexible Interface Card

ATM and DSL Digital Subscriber Line (DSL) is a simple, but highly efficient broadband technology

that achieves great data transmission capacity over existing copper wiring by using

the digital code modulation technology. The ADSL cards available for 6000

Routers allow medium-to-small-sized enterprises to access the Digital Subscriber

Line Access Multiplexer (DSLAM) equipment via Public Switched Telephone

Network (PSTN) and then the Internet.

Asynchronous Transfer Mode (ATM) transmits, multiplexes, and switches

information in cells. 6000 Routers provide 155Mbps cards supporting ATM

Adaption Layer Type 5 (AAL5) and offering the traffic services like Constant Bit

Rate (CBR), Variable Bit Rate (VBR) and Unspecified Bit Rate (UBR). Hence, such

routers are well-suited to the high-speed data service and the transmission of large

8CHAPTER 2: INTRODUCING THE ROUTER 6000 FAMILY

packets, which implement connection between medium-and-small-sized

enterprise networks and ATM networks.

MPLS Multiprotocol Label Switching (MPLS) is a combination of IP and ATM

technologies. This method replaces the IP header with a short and length-fixed

label as traffic identifier. This information is used by the router to make forwarding

decisions. This provides faster forwarding speed while getting support from IP

routed protocols and control protocols. This meets the requirements that various

new applications put on the network. MPLS VPN is a Virtual Private Network

technology that implements the interconnection of private networks via Label

Switched Paths (LSPs). As LSP is a tunnel across the public network on its own,

MPLS has an intrinsic advantage in terms of VPN implementation. 6000 Routers

usually act as Label Edge Routers (LERs) to connect to an MPLS domain with

non-MPLS domain or connect to MPLS domains of different service providers.

Data security and

reliability ■Support for NAT. Besides some basic functions, the NAT available for 6000 can

limit concurrent connections to a single user, and thus alleviate the negative

impact caused by malicious resources without compromising the normal

network applications. NAT of 6000 also provides the ALG (Application Layer

Gateway) function to FTP and ICMP.

■Support the authentication protocols such as PAP, CHAP, and data RADIUS

■Implement packet filter and stateful firewall for preventing the intrusion from

an external networks.

■Support VPN (including GRE, L2TP, and MPLS) and provide IPSec, and IKE,

hence ensuring the security of the private networks in an Internet environment.

■Support the Backup Center and Virtual Router Redundancy Protocol (VRRP)

technologies, enhancing the robustness and reliability of the network by

providing a backup scheme in case of communication line or device failures. So

far, backup center supports backup load sharing.

■Support hot swap of fans, interface cards, and power module to ensure high

reliability.

Online software

upgrading You can upgrade the application programs and Boot ROM programs, and add new

features and functions on line as needed.

Abundant fault isolation

methods ■You can monitor the states of system configurations, system service channels,

and system resources, as well as fault indication via console and network

management host.

■You can monitor the FIC running state by observing the LEDs on FIC panels.

■You can use in-service system test, out-of-service system test. In addition,

loopback test and hardware key module self-test are allowed.

Router Model and Structure 9

Router Model and

Structure 3Com 6000 Routers include 3Com 6040, and 6080. These models are similar in

chassis structure and layout. They use the mid-backplane allowing front and rear

card insertion and can be mounted in 19-inch standard racks.

6040 Components The 6040 has five slots on the front panel, using slot 0 for the main control unit

and slots 1 through 4 for FICs.

Two PSUs, working in 1+1 backup mode, can be installed in 6040 from the rear of

the chassis. The PSUs provide AC power. The fan module is located at the left rear.

Both PSU and fan module are hot swappable.

6080 Components The 6080 has nine slots on the front panel, using slot 0 for the main control unit

and slots 1 through 8 for FICs.

Two PSUs, working in 1+1 backup mode, can be installed in the 6080 from the

rear of the chassis. The PSUs provide AC power, and you may make selection as

needed. The fan module is located at the left rear. Both PSU and fan module are

hot swappable.
