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.

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.

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.
