10 CHAPTER 1: 3COM ROUTER INTRODUCTION
New Features of the
3Com Router 1.x
New features have been added to the 3Com Router1.10.
Support New Interfaces E3 and CE3 Interfaces
Both E3 and E1 are part of the ITU-T digital carrier architecture and are used in
most regions beyond North America. The data transmission speed of E3 is
34.368
Mbps and the line code is HDB3. E3/CE3 interfaces support the link layer
protocols including PPP, HDLC, Frame Relay, LAPB, and X.25, as well as the
network protocol such as IP. Similar to E1/CE1, E3/CE3 interfaces can work in two
operating modes, namely, E3 mode and CE3 mode.
When working in E3 mode, an E3/CE3 interface is a timeslot-less interface of
the bandwidth of 34.368 Mbps.
When working in CE3 mode, it can multiplex/demultiplex 16 channels of E1
signals. The E3-to-E1 multiplexing is compliant with the G.751 and G.742
provisions of ITU-T. In addition, each E1 interface can be divided into 32
timeslots.
E1-F/T1-F Interface
E1-F and T1-F interfaces refer to the fractional E1 and T1 interfaces, which are
equivalent to the simplified CE1/PRI and CT1/PRI interfaces. In essence, they are a
low-cost approach to E1/T1 access. In a simple E1 or T1 access application
requiring neither division of multiple channel groups nor ISDN PRI, either the E1-F
or T1/F interface will be a good choice.
Null Interface
The functions of the Null interface are similar to those of null devices supported by
many operating systems. It is always in UP status, but cannot forward data packets
or configure IP addresses or encapsulate other protocols. Null interface is a virtual
interface with software characteristics. Any network data packet sent to this
interface will be dropped.
FRoIP and FRoISDN Frame Relay over IP
As IP networks have gained wider acceptance, Frame Relay (FR) applications have
relied on IP networks for data communication and interconnection between
networks. FRoIP technology enables IP networks to carry FR data by establishing a
GRE tunnel across the IP network to connect the two FR networks at both ends of
the IP network.
Frame Relay over ISDN
Frame Relay over ISDN provides a method for accessing the Frame Relay network
based on ISDNs and the related devices. This shortens the time for users to access
and lowers the cost of leased lines.
The Frame Relay over ISDN is mainly used in the following two aspects:
The simplest application is to take Frame Relay over ISDN as the main
communications method. That is, all the routers support Frame Relay over
ISDN, and the individual routers can directly access the Frame Relay networks
(without TA adapters) to communicate.
New Features of the 3Com Router 1.x 11
Combined with BDR, Frame Relay over ISDN can be taken as the backup
communication method for Frame Relay.
Multilink Frame Relay The Multilink Frame Relay (MFR) feature introduces functionality based on the
Frame Relay Forum Multilink Frame Relay UNI/NNI Implementation Agreement
(FRF.16). This feature provides a cost-effective way to increase bandwidth for
particular applications by enabling multiple serial links to be aggregated into a
single bundle of bandwidth. MFR is supported on User-to-Network Interfaces (UNI)
and Network-to-Network Interfaces (NNI) in Frame Relay networks.
FR Compression FR compression technology is used to compress the FR packets for the purpose of
effectively saving the network bandwidth and decreasing the network load, and
hence to implement data transmission over FR networks with high efficiency.
3Com Routers follow the FRF.9 standard for FR compression. FR compression can
achieve a significant effect on a FR line with low bandwidth. FR interfaces fall into
two categories, namely, point-to-point interface and multipoint interface.
Bridge Bridges are a type of network devices that connect LANs at the data link layer for
data transmission among them. For some small or remote networks, a bridge can
reduce the network maintenance cost and free the network terminal subscribers
from making special settings for the devices. In addition, its network connection is
no difference from a HUB.
3Com Routers support transparent bridging and are compatible with IEEE 802.1d.
The routers support the STP and bridging functions defined in IEEE 802.1d and
support bridging on the links encapsulated with PPP, HDLC, X.25, or Frame Relay,
as well as bridging on VLAN sub-interfaces and BDR. Furthermore, the routers can
implement multi-port binding and load sharing.
IP Count IP count implements accounting on the incoming and outgoing packets as well as
the packets denied by the firewall on the routers. When implementing IP count,
whether the packets match the count list rules and whether the packets are
denied by the firewall, are two standards by which the router sorts the
bidirectional packets for count. When making data statistics, both the number of
packets and the total bytes are recorded.
Virtual Router
Redundancy Protocol
(VRRP)
Virtual Router Redundancy Protocol (VRRP) is a fault tolerant protocol. Normally,
the default route set for a host in a network takes the GW route of the network as
the next hop. Through the default route, the host can carry out the
communications with the external networks. If the GW route fails to work, all the
hosts that take it as the next hop on the segment will be unable to communicate
with the outside. VRRP can fulfill the router redundancy by assigning multiple
routers into a router group. Thus, whenever a member fails to work, a backup
router will take up the work of the failed router and thus can ensure the normal
communications between the hosts on the network and the outside.

Basic Configuration and Management of the System
Establish
Configuration
Environment
The 3Com Router 1.x supports local and remote configuration, and the
configuration environment can be established in the following ways:
Local Configuration
Environment via Console
Port
The local configuration environment can be established via the console port
(configuration interface).
1 As shown in Figure 2, the local configuration environment can be established via
the console port just by connecting the serial port of the computer with the
console port of the router via a standard RS-232 cable.
Figure 2 Establish a local configuration environment via configuration interface
On 3Com modular routers the CONSOLE port and AUX port are on the front of
the unit, while other ports are on the rear of the unit. The above diagram shows
the rear of the unit. For details, please refer to the 3Com Installation Guide.
2 Run a terminal emulator application such as HyperTerminal of Win9X on the
computer to establish a new connection. Select an RS-232 serial port on the
computer, set the terminal communication baudrate parameters as 9600 bps, 8
data bits, 1 stop bit, no parity and no flow control, and select the terminal
emulation type as VT100, as shown in the following diagram (“HyperTerminal”
setting interface in Windows 9X).

after the self-test to display the prompt “Username:” and “password:”. Type in
the correct username and the password, then enter the system view of Router.

4 Enter the command to configure the router or view the running status of the
router. Enter “?” to get help when necessary. For details of specific commands,
please refer to the following chapters.
Remote Configuration
Environment via Async
Serial Port
The router powers on, then creates a remote configuration environment by
connecting to the asynchronous serial ports of the router (including
synchronous/asynchronous serial port, AUX interface, i.e., auxiliary interface, etc.)
via modem dial-up. Detailed below is the description on how to establish a remote
configuration environment via asynchronous serial port, with AUX interface as an
example.
To establish a remote configuration environment via an asynchronous serial port of
the router, pre-configure it to flow mode. For specific setting method, please refer
to the Terminal Service chapter in this manual.
The modem connected to the asynchronous serial interface should be set to
auto-answer mode.
1 As shown in Figure 7, connect a modem to computer serial port and another
modem to the routers asynchronous serial port (AUX interface in the diagram).
Figure 7 Establish a remote configuration environment
2 Run a terminal emulator application, such as HyperTerminal of Win9X, on the
computer to establish a new connection. Select the RS-232 serial port on the
computer for actual connection; set the terminal communication parameters to
9600 baud rate, 8 data bits, 1 stop bit, no parity, no flow control or hardware flow
control, and select the terminal emulation type as VT100, the same as the
connection established via the console port.
3 Before powering on the router, power on its external modem. Initialize the router
via AT command, and then dial on the remote computer to establish a connection
with the router, as shown in the following figure.
