Overview

Introduction

MSR 20 Routers were self-developed for use on enterprise-level networks. Depending on the network size, MSR 20 Routers can be either core routers on small and medium enterprise networks, or access routers for network branches on some large-sized enterprise networks. Therefore, MSR 20 Routers are suitable for the application on the carrier-level networks, such as telecom management networks and billing networks. MSR 20 Routers adopt modular design and provide a wide range of optional smart interface cards (SICs). The MSR-20, MSR 20-21 and MSR 20-40 are available with AC-powered units.

Currently, the MSR 20 includes the following models:

• MSR 20-20

• MSR 20-21

• MSR 20-40

Router Model and Structure

The MSR 20 Routers include MSR 20-20, MSR 20-21, and MSR 20-40. These three models are similar in chassis structure and layout. All of them can be put on the tabletop and can be mounted in 19-inch standard racks. The following subsections will give you more details about these three models.

Installation Preparations

Requirements on Environment

The MSR 20 routers are designed for indoor applications. To ensure the normal operation and prolong their service life, the following requirements for installation site must be met.

Requirements on Temperature/Humidity

To ensure the normal operation and prolong their service life, certain requirements on temperature and humidity in the equipment room shall be met. If the relative humidity is too high, the insulation materials in it will deteriorate easily or even lead to electric leakage. Sometimes this will result in change to the mechanical performance of the materials and rusting of the metal components. If the relative humidity is too low, the fastening screw will become loosen due to shrinkage of the isolation spacer. In an environment with dry climate, static electricity may be produced, putting the CMOS of the router to risk. High temperature is of the greatest risk: for it will significantly degrade the router’s reliability, speed up aging process of the insulating materials, and shorten the service life of the router.

The requirements on the temperature and humidity for MSR 20 are shown in the following table:

Table 9 Temperature/humidity requirements in the equipment room

Temperature Relative humidity

0°C to 40°C (32°F to 104°F) 5% to 90% (non-condensing)

Requirements on Cleanness

Dust is harmful to the safe operation of the Router. Dust on the chassis may result in static absorption, t hus causing poor contact of the metal connection components or points. Especially under the condition of low indoor humidity, dust is easier to be absorbed.

The requirements on the dust concentration and diameter are shown in the following table:

Table 10 Limitation on dust content in equipment room

Diameter (μm) 0.5 1 3 5

Concentration (particle/m³)

Besides the dust specifications, the equipment room of the Router should also meet the rigorous requirements for the content of salt, acid and sulfide. These harmful gases could accelerate the metal erosion and aging process of some parts. The specific limits of these harmful gases as SO NH

and CI2 are given in the following table.

Requirements on Electrostatic Discharge Prevention

Although many antistatic considerations have been given to MSR 20, damage to the router’s circuit or even the whole equipment may still happen when the static electricity exceeds the tolerance threshold.

In the communication network to which the routers are connected, static induction mainly comes from two aspects: external electric fields such as outdoor high voltage power line or thunder and internal environment like flooring materials or the whole equipment structure. Thus, the following should be considered to safeguard the equipment against ESD.

• Make sure that the equipment and the floor are well grounded.

• The equipment room is dust-proof.

• Maintain an appropriate humidity and temperature.

• Wear an ESD-preventive wrist strap and uniform when contacting the circuit board.

• Place the uninstalled circuit board on the antistatic workbench, with its face upward, or put it into

the static shielding bag.

• When observing or removing the uninstalled circuit board, please touch the edge of the circuit

board, and avoid contacting the devices on it.

Requirements on Electromagnetic Environments

The interference sources, no matter where they come from, affect the routers with capacitance coupling, inductance coupling, radiation of electromagnetic wave, common impedance (including the grounding system) or conducting line (power line, signal line and transmission line etc.). So the following should be considered:

• Take effective measures to prevent the power system from being interfered with by the power grid

system.

• Use an earthing system or lightning protection grounding different from that for the power supply

equipment and keep them as far as possible.

• Keep the router far away from the radio launcher, radar launcher, and high-frequency devices

working in high current.

• Use electromagnetic shielding when necessary.

Requirements on Preventing Lightning

Although many measures have been taken to protect MSR 20 from lightning, if the lightning intensity exceeds a certain range, damage to the router may still happen. To protect the router from lightning better, the following should be considered:

• Ensure the PGND wire of the chassis is well grounded.

• Ensure the ground point of the socket of AC power supply is well grounded.

• To enhance the lightning protection capability of the power supply, a lightning arrester could be

installed at the input end of the power supply.

• As for the signal line outdoors to which the interface modules of MSR 20 routers are connected,

such as ISDN line, telephone line, E1/T1 line, etc, a special lightning arrester should be installed at the input end of the signal line to enhance the lightning protection capability.

Checking the Rack

When installing MSR 20 Routers, observe the following:

• There is spacing reserved at the air inlet and outlet in the router so as to facilitate the radiation of

the router cabinet.

• Make sure that the rack has a good ventilation system.

• Make sure that the rack is sturdy enough to support the weight of the device and the installation

accessories.

• Make sure that the rack is well-grounded.

Safety Precautions

Routers play a key role in data communications network. Please pay attention to the following:

WARNING: indicates that this operation is incorrect and may seriously damage the router or

endanger the operator. Please follow the correct operation procedures for sake of safety.

CAUTION: indicates that during the installation and usage of the router, the operation needs

attention. If this operation is performed incorrectly, it might affect the operation of the router.

When installing or working on the router, you are recommended to:

• Keep the router far away from the heat sources and water/liquid.

• Make sure that the router has been correctly grounded.

• Wear an ESD-preventive wrist strap in installation and maintenance, making sure that the strap has

good skin contact.

• Do not hot swap the interface modules and interface cards of the router.

• Do not hot swap any cable.

• Correctly connect the interface cable for the router. Do not connect the telephone cable (including

the ISDN cable) to the AUX port or the console port.

• Use laser with caution. Do not directly stare into apertures or fiber-optic connectors that emit laser

radiation.

• Adopt uninterrupted power supply (UPS).

Physical dimension (H × W × D) (excluding feet and mounting brackets)

Installing the Router on a Workbench

In many circumstances, you may not own a 19-inch standard rack. Usually, the router will be installed on a clean workbench. The operations are very simple, but still, you should be aware of the following items:

• Ensure the stability and well-grounding of the workbench.

• Reserve a space of 10 cm (3.9 in.) around the router for heat dissipation.

• Do not place heavy objects on the router to avoid extruding the device and affecting heat

dissipation performance.

Installing the Router in a Cabinet

You can install an MSR 20 router in a 19-inch standard cabinet, such as an H3C N68 rack. For the installation of an N68 rack, refer to N68 Cabinet Installation Guide.

Mounting brackets

Figure 8 Mounting brackets

(1) Left-front mounting bracket (2) Right-front mounting bracket (3) Left-rear mounting bracket (4) Right-rear mounting bracket

Installation process

Step1 Check the grounding and stability of the rack. Use the screws to fix the mounting brackets at both sides

of the front panel or the rear panel of the router.

Step2 Put the router in a rack tray. For MSR 20-40 routers, use dedicated ears mounted on the rear panel if no

tray is available. Depending on the actual situation, slide the router along the chassis guides to an appropriate place.

Step3 Fasten the mounting brackets with the recess screws to fix the router in the rack horizontally and firmly.

The specifications of recess screws should satisfy the installation requirements and the surface of the screws should be anti-rust.

Installing Generic Modules

Installing generic modules includes installing the memory, ESM cards, and FICs. For more information about the memory and ESM cards and their installation, refer to Chapter 6 “Hardware Maintenance” in this manual. For more information about FICs and their installation, refer to MSR Series Routers Interface Module Manual.

Connecting the PGND Cable

WARNING!

The correct connection of the protection ground (PGND) cable on the router chassis is an essential safeguard against lightning strokes and EMI. You need to correctly connect the PGND cable when installing or using the router.

The power input end of MSR 20 router is connected to a noise filter. The neutral point of the noise filter is directly connected to the chassis and is called protection grou nd ( PGND) . The PGN D wire must be well grounded, so as to safely conduct the faradism and leaky electricity to the earth ground, and thereby improve the capability of the whole device to guard against the electromagnetic interference. This PGND wire can also protect the router against the lightning caused by the connection with the external network lines, such as E1/T1 line, ISDN/PSTN line.

The grounding screw of MSR 20 Router, which is marked with grounding label, is located near the AC power socket and its switch on the rear panel of the chassis, as shown in the following figure:

Figure 11 Grounding terminal of the router

Use a PGND wire to connect the screw to the earth ground, and the grounding resistance should not be greater than 5-ohm. Likewise, if the router is installed in a 19-inch standard rack, this rack is required to be grounded too.

WARNING!

When the router is in normal operation, it is required to be well reliably avoid lightning, which may damage the router itself and even the peer device.

Configuration Fundamentals

In general, the configuration steps are as follows:

Step1 Before configuring the router, the networking requirements should be made specific, which include

networking purpose, the role of the router in the network, the division of subnets, WAN type and transmission medium, the network security policy and reliability.

Step2 Based on the above requirements, draw a clear and integrated networking diagram. Step3 Configure the WAN interface of the router. First, configure the physical operating parameters (e.g., the

operating mode of the serial interface, baud rate and synchronous clock) of the interface according to the transmission medium of the WAN. For the dial-up interface, the user also needs to configure DCC parameters. Then, configure the link layer protocol encapsulated on the interface and the related operating parameters according to the WAN type.

Step4 Configure the IP addresses or IPX network numbers of all the interfaces on the router according to the

division of the subnets.

Step5 Configure the routes. If it is necessary to enable a dynamic routing protocol, the user should configure

the related operating parameters of the protocol.

Step6 If special security is required, perform the security configuration for the router. Step7 If special reliability is required, perform the reliability configuration for the router.

See MSR Series Routers Configuration Guide for the configuration details of the protocols or functions of the router.

Basic Configuration Procedures

Command Line Interface

Characteristics of the command line interface

The command line interface of MSR 20 Routers provides a number of configuration commands, which can be used to configure and manage the router. The command line interface has the following characteristics:

• Performs the local configuration through Console port

• Performs the local or remote configuration through telnet command, which can be used to directly

log on and manage other routers.

• Users can enter ? anytime to get online help.

• Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose the availability of

the network.

• Provides all kinds of detailed debugging information to diagnose network faults.

• The command line interpreter adopts fuzzy search for the keywords of the command. If the user

enters the conflict-free keyword for a command, the command will be interpreted accordingly. For example, for a display command, the user can just enter dis.

Command line interface

The command line interface of MSR 20 routers provides plenty of configuration commands. All the commands are grouped in system view. Each group corresponds to a view. The user can use these commands to switch between different configuration views. In general, only certain commands can be executed under a particular view. But some common commands (such as ping and display current-configuration) can be executed in all views.

Arranging Slots and Numbering Interfaces

Slot arrangement

The MSR 20 provides many types of interfaces, such as console, AUX, Ethernet, serial (synchronous/asynchronous), and asynchronous port. The following describes how these interfaces are numbered.

Figure 25 Slot arrangement on the MSR 20-20

(1) Slot 1 (2) Slot 2

Figure 26 Slot arrangement on the MSR 20-21

(1) Slot 1 (2) Slot 2

Figure 27 Slot arrangement on the MSR 20-40

(1) Slot 1 (2) Slot 2 (3) Slot 3 (4) Slot 4

Interface numbering

The MSR 20 Router interface adopts “two dimension” numbering rules, shown in the following:

• The interfaces are represented by interface-type X/Y, where interface-type can be serial,

asynchronous, or Ethernet, and so on; X specifies the slot number; Y specifies the interface number.

• Fixed interfaces are on Slot 0.

• Different interfaces on an interface module share the same slot number X.

• For every interface, Y starts from 0 and Y indicates the interface sequence on the interface module,

from left to right.

If you install an SIC-1FEA and an SIC-4FSW respectively in SLOT1 and SLOT2 on the AR MSR 20-20, the Ethernet interfaces are numbered as follows:

• Fixed Ethernet interfaces are Ethernet 0/0 and Ethernet 0/1;

• The Ethernet interface on the SIC-1FE is Ethernet 1/0;

• The Ethernet interfaces on the SIC-4FSW module are Ethernet 2/0, Ethernet 2/1, Ethernet 2/2 and

Ethernet 2/3.

Software Maintenance

Introduction

Files

BootWare program file

The file is used to boot an application. A complete BootWare file includes two segments: basic and extended.

• The basic section is used for the basic initialization of the system.

• The extended section provides abundant human-computer interaction (HCI) functions and is used to

initialize interfaces and update the applications and the boot system.

• After the basic section is loaded, you can load and update the extended section through the menu

of the basic section.

Application files

The router is available with Dual Image function. By default, the system defines and attempts to boot in order with three boot files: main, backup, and secure, provided they are available with CF card. If the router fails to boot with the secure boot file, it prompts the boot failure. For more information about the boot files, refer to section “

The following table gives default names and types of boot files.

Table 17 Default names and types of the boot files

• You can modify the name of an application file in storage after the application file is loaded. You canno

modify the file type of a type S application file, but you can modify the file type of type M/B and N application files in the BootWare menu or using commands after the application program boots.

• Secure boot file is the last resort for system boot. You can download it in the BootWare menu and mus

name it secure.bin. However, you cannot modify this file or change the type of another file to S. If you change the name of the secure boot file with the rename command after the system boots, the file is removed from CF card. To use the secure boot file after that, you need to download it again.

• You can store type M, B, S files in storage devices, but only one for each type in each storage device. For

example, if a type M+B file exists in the Flash memory, there will be no type M or B file. If you chan the type of a file to B, the M+B file will become a type M file.

Configuration file

The file stores configuration information of the router.

By default, the system defines three configuration files for booting: main, backup, and default file. If the three configuration files are loaded in a storage device, the system selects them in sequence until the router is successfully loaded. To change the sequence of these configuration files or modify them, refer to “

Maintaining Application and Configuration Files” on page 53.

rams for system boot can be type M, B and S, but not type N. You can store them

e the file type of another file to B, the M+B file becomes a type M file.

The details about the three configuration files and file selection sequence are as follows:

• Main configuration file: The configuration file used for booting by default. The file type is M.

• Backup configuration file: The file type is B. The system uses the backup configuration file when it

fails to boot using the main configuration file.

• Default configuration file: The file type can be M, B, or N. The system uses the default configuration

file when it fails to boot using the backup configuration file. If the system fails to boot using the default configuration file, it boots with null configuration. The name of the default configuration file varies with router brands. The main and backup configuration operations on the default configuration file are the same as those on common configuration files.

NOTE:

• The configuration files for system boot can be type M, B and default configuration file of type N, but no

non-default configuration file of type N (i.e. neither M nor B).

• You can modify the file name of a configuration file in storage using the command after the

configuration file is loaded. You cannot modify the type of the default configuration file, but you can modify the file type of type M/B and N configuration files in the BootWare menu or usin after the configuration file is loaded.

Maintaining Application Program and Configuration Through Command Lines

After the router is booted, you can upgrade and back up an application program, and back up and restore configurations through command lines.

Maintaining the Router Through TFTP Server

In the TFTP service, the router is TFTP client and the file server is the TFTP server. You can enter commands on the terminal to upload or download configuration files or application programs to or from the file server.

Setting up a configuration environment

Set up a hardware environment (refer to Upgrading an Application Program Through an Ethernet

Interface on page

Figure 29 Network diagram for maintenance through command lines

46 for details), and point the server path to the directory where the file is stored.

Configure the IP addresses of both sides on the same network. For example, the IP address of the TFTP server is set to 192.168.0.1, and that of the Ethernet interface connected to it (Ethernet 0/0 in this example) is set to 192.168.0.2. Use the ping command to check whether the connection successful.

Backing up and restoring application programs and configuration files

After setting up the environment, perform the following operations on the console terminal:

Use the dir command to view the files in the current file system:

<SYSTEM>dir Directory of cfa0:/ 0 drw- - Dec 20 2007 09:18:22 logfile 1 -rw- 22165484 Dec 20 2007 09:18:10 update.bin 2 -rw- 1181 Dec 20 2007 09:42:54 startup.cfg 4 -rw- 22165484 Dec 20 2007 09:42:28 main.bin 252904 KB total (208940 KB free) File system type of cfa0: FAT16 <SYSTEM>

Use the following command to upload the startup.cfg file to the TFTP server and save it as startup.bak:

<SYSTEM>tftp 192.168.1.1 put startup.cfg startup.bak File will be transferred in binary mode Sending file to remote tftp server. Please wait... \ TFTP: 1045 bytes sent in 0 second(s).

File uploaded successfully.

Use the following command to download the startup.cfg file from the server to the router:

<SYSTEM>tftp 192.168.1.1 get startup.cfg startup.cfg The file startup.cfg exists. Overwrite it?[Y/N]:y Verifying server file... Deleting the old file, please wait... File will be transferred in binary mode Downloading file from remote tftp server, please wait...\ TFTP: 1045 bytes received in 0 second(s) File downloaded successfully.

If a startup.cfg file already exists in the router, the system prompts you whether to overwrite it. You can type Y or y to overwrite it.

Upgrading the application programs

After setting up the environment, perform the following operations on the device (the application name is msr.bin for example):

Use the save command to save the current configuration:

<SYSTEM>save The current configuration will be written to the device. Are you sure? [Y/N]:y Please input the file name(*.cfg)[cfa0:/startup.cfg] (To leave the existing filename unchanged, press the enter key):

Use the dir command to view the application files and the available space of the CF card (ensure that the CF card has enough space to store a new application):

252904 KB total (208940 KB free) File system type of cfa0: FAT16 <SYSTEM>

Download the application msr.bin to the CF card of the device through TFTP:

<SYSTEM>tftp 192.168.1.2 get msr.bin

File will be transferred in binary mode Downloading file from remote TFTP server, please wait...\ TFTP: 15054340 bytes received in 34 second(s) File downloaded successfully.

Use the boot-loader command to set the startup file for the next startup to msr.bin:

<SYSTEM>boot-loader file cfa0:/msr.bin main This command will set the boot file. Continue? [Y/N]:y The specified file will be used as the main boot file at the next reboot on slot 0! <SYSTEM>

Use the display boot-loader command to view the startup file information of the device:

<SYSTEM>dis boot-loader The boot file used at this reboot:cfa0:/main.bin attribute: main The boot file used at the next reboot:cfa0:/msr.bin attribute: main Failed to get the backup boot file used at the next reboot! Failed to get the secure boot file used at the next reboot! <SYSTEM>

Make sure that the configured startup file is correct, and then use the reboot command to reboot the device:

<SYSTEM>reboot Start to check configuration with next startup configuration file, please

wait.........DONE!

This command will reboot the device. Current configuration may be lost in next startup if you continue. Continue? [Y/N]:y

After the device is rebooted, use the display boot-loader command to view the startup file information of the device to make sure that the current application of the device is msr.bin.

CAUTION:

• When you back up a file, the file will directly overwrite the one with the same name on the server.

• The backup configuration file can be modified by a text editor. You can change the configuration by

downloading the modified configuration file and the modification takes effect after you reboot the router. Similarly, you can also up

rade the main application file by downloading a new application file

to overwrite the original main application file.

• The above operations are performed in user view.

• Before upgrading an application, save the current configuration of the device.

• When upgrading an application, use the dir command to view the size of the downloaded file and

whether the file is the same as that on the server to ensure that the application is complete and correct.

Maintaining the Router Through FTP Server

Maintaining the router serving as the FTP server

File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It is mainly used for file transfer between remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service, but does not provide any access authorization and authentication mechanism.

In the FTP service, the router can serve as the FTP server. You can run the FTP client to log in to the router access files on the router.

Before using FTP, you need to install the FTP client. No FTP client is shipped with the H3C MSR 20 routers. In the following example, the FTP client application program is the built-in Windows XP FTP client.

Step1 Set up a hardware maintenance environment, as shown in the following figure:

Figure 30 Maintain the router serving as the server

Router

TFTP/FTP Server

Console cable

Ethernet cable

TFTP/FTP Client

Configure the IP addresses of both sides on the same network. In this section, the IP address of the FTP client (PC) is set to 192.168.1.1, and that of the connected Ethernet interface on the router (Ethernet 0/0) is set to 192.168.1.2. Use the ping command to check the connectivity.

Step2 Enable the FTP service.

After configuring authentication and authorization, you can enable the FTP service. The FTP server supports multi-user access. Upon receiving the request from a remote FTP client, the FTP server executes an action accordingly and returns the execution result to the client. Use the following command to enable the FTP service:

[SYSTEM]ftp server enable % Start FTP server

Add an authorized username and password:

[SYSTEM]local-user guest [SYSTEM-luser- guest]service-type ftp [SYSTEM-luser- guest]password simple 123456

Step3 Maintain the router.

After enabling the FTP service and configuring the username and password, you can enable the FTP client on the PC. In the following example, the FTP client application program is the built-in Windows XP FTP client.

Type ftp in the DOS window, and the system prompt is changed to ftp>:

C:\Documents and Settings\Administrator>ftp ftp> ftp> open 192.168.1.2 Connected to 192.168.1.2. 220 FTP service ready. User (192.168.0.2:(none)): guest 331 Password required for guest Password: 230 User logged in.

After you correctly enter the username and password, the system prompts login success. You can then maintain the router, for example, modify transmission mode and local path, and back up files. In this example, the main.bin file on the router is copied to the PC.

ftp> binary 200 Type set to I. ftp> lcd c:\temp Local directory now C:\temp. ftp> get main.bin main.bin 200 Port command okay. 150 Opening BINARY mode data connection for main.bin. 226 Transfer complete. ftp: 14323376 bytes received in 16.81Seconds 851.87Kbytes/sec.

Use the following command to recover the backup file to the router:

ftp> put main.bin main.bin 200 Port command okay. 150 Opening BINARY mode data connection for main.bin. 226 Transfer complete. ftp: 14323376 bytes sent in 8.29Seconds 1727.37Kbytes/sec. ftp> quit 221 Server closing.

Maintaining the router serving as a client

You can also maintain the router file system by setting up an FTP environment where the router serves as an FTP client.

Step1 Set up a maintenance environment.

Figure 31 Maintain the router serving as a client

The router serves as the client, while the PC running FTP server program serves as the FTP server. Set the FTP server path and add username and password for the router.

Configure the IP addresses of both sides on the same network. In this section, the IP address of the FTP server is set to 192.168.1.1, and that of the connected Ethernet interface on the router (Ethernet 0/0 in this example) is set to 192.168.1.2. Use the ping command to check the connectivity.

Step2 Maintain the router through the terminal connected with the console interface of the router.

The following gives an example:

<SYSTEM>ftp 192.168.1.1 Trying 192.168.1.1 ... Press CTRL+K to abort Connected to 192.168.1.1. 220 3Com 3CDaemon FTP Server Version 2.0 User(192.168.1.1:(none)):guest 331 User name ok, need password Password: 230 User logged in

[ftp]

Step3 Use the following commands to maintain the router.

Here, the get and put commands are used to restore and back up files.

[ftp]get main.bin main.bin cfa0:/main.bin has been existing. Overwrite it?[Y/N]:y 200 PORT command successful. 150 File status OK ; about to open data connection 226 Closing data connection; File transfer successful. FTP: 14323376 byte(s) received in 69.256 second(s) 206.00K byte(s)/sec. [ftp]put main.bin main.bin 200 PORT command successful. 150 File status OK ; about to open data connection 226 Closing data connection; File transfer successful. FTP: 14323376 byte(s) sent in 15.974 second(s) 896.00Kbyte(s)/sec. [ftp]quit 221 Service closing control connection

After an application is uploaded to the device, you can use the boot-loader command to upgrade the device. For the upgrade procedure, refer to “

Upgrading Procedure

Trivial File Transfer Protocol (TFTP), a protocol in the TCP/IP protocol suite, is used to transfer trivial files between clients and the server. It provides not-so-complex and low-cost file transfer services. TFTP provides unreliable data transfer services over UDP and does not provide any access authorization and authentication mechanism. It employs timeout and retransmission to guarantee the successful delivery of data. The TFTP software is much smaller than the FTP software in size:

File Transfer Protocol (FTP) is an application-layer protocol in the TCP/IP protocol suite. It mainly transfers files among remote hosts. Over TCP, FTP provides reliable and connection-oriented data transfer service but does not provide access authorization and authentication mechanism.

Configure the gateway IP address if the server and the client are not on the same network segment.

Step1 Set up an upgrade environment.

Figure 32 Set up a TFTP/FTP upgrade environment

Connect Ethernet 0/0 to a PC with a crossover cable. Start the TFTP/FTP program on the PC, and set the path of TFTP/FTP server to directory of the application program. You need to set username and password if FTP server is used.

CAUTION:

No TFTP/FTP Server is shipped with the MSR 20 routers.

Step2 Modify Ethernet interface parameters. For details, refer to “Configuring Ethernet Interface Parameters”

on page

extended BootWare, or basic BootWare.

Upgrading BootWare Through Serial Interface

Use XModem to upgrade BootWare through a serial interface.

XModem Protocol Overview

To upgrade the BootWare and application program through a serial interface, use the XModem protocol.

XModem is a file transfer protocol widely used for its simplicity and good performance. Modem transfers files through serial interfaces. It supports transmission of packets in 128 bytes and 1 KB, error check (checksum and CRC), and error retransmission (generally the maximum number of retransmission attempts is 10).

XModem transmission is completed by the cooperation of a receiver and a sender. The receiver sends a negotiation message to the sender to negotiate an error check method. After the negotiation, the sender

starts to transmit data packets. After a complete packet is received, the receiver checks the packet using the agreed method.

• If the check is passed, the receiver sends an acknowledgement message to the sender. Upon

receiving the message, the sender continues to send the next packet.

• If the check fails, the receiver sends a negative acknowledgement message to the sender. Upon

receiving the message, the sender retransmits the packet.

Modifying Serial Interface Parameters

Sometimes, we need to increase the baud rate of a serial interface to save software upgrade time, or lower the baud rate to guarantee transmission reliability. This section describes how to adjust the baud rate of a serial interface.

Enter 2 in the main BootWare menu to enter the serial interface submenu. Then, enter 5 and the system prompts for changing a baud rate.

==============================<BAUDRATE SET>============================== |Note:'*'indicates the current baudrate | | Change The HyperTerminal's Baudrate Accordingly | |--------------------------<Baudrate Avaliable>--------------------------| |<1> 9600(Default)* | |<2> 19200 | |<3> 38400 | |<4> 57600 | |<5> 115200 | |<0> Exit | ========================================================================== Enter your choice(0-5):

Select a proper baud rate, 5 for 115200 bps for example. The following prompt appears:

Baudrate has been changed to 115200 bps. Please change the terminal's baudrate to 115200 bps, press ENTER when ready.

Since the baud rate of the serial interface on the router is changed to 115200 bps, whereas the terminal baud rate remains 9600 bps, they cannot communicate with each other. Change the baud rate on the console terminal to the one selected for downloading software.

Perform the following configurations on the console terminal:

Figure 33 Disconnect terminal

Select File > Properties, and press Configure… to change the baud rate to 115200 bps:

Figure 34 Modify baud rate

Select Call > Call to establish a new connection.

Figure 35 Establish a new connection

Press Enter to view the current baud rate and return to the previous menu.

The system displays:

The current baudrate is 115200 bps

NOTE:

Restore the baud rate in the HyperTerminal to 9600 bps after upgrading the BootWare. This ensures tha the information can be displayed on the console terminal after system boot or reboot.

Upgrading BootWare

First, enter 7 in the main BootWare menu (refer to “Main BootWare Menu” on page 41 ) to enter the BootWare operation submenu, through which all BootWare operations are performed. For details, refer to “

Dealing with Password Loss

Use the following solutions when your BootWare password, user password or Super Password is lost.

User Password Loss

You cannot enter the system if you lose your user password. In this case, you can boot the system by ignoring the system configuration. Perform the following operations to set a new user password:

Step1 Enter the main BootWare menu, and enter 6 to boot the system by ignoring the system configuration.

The system displays:

Flag Set Success.

The system prompts the setting succeeds.

Step2 When the main BootWare menu appears again, enter 0 to reboot the system. Step3 Set a new password in system view.

[SYSTEM]user-interface console 0 [SYSTEM-ui-console0]authentication-mode password [SYSTEM-ui-console0]set authentication password simple 123456

The above information indicates that the password authentication is adopted on the console interface and the password is set to 123456 and stored in plain text.

NOTE:

• After reboot, the system runs the initial default confi

in the Flash memory. To restore the original configuration, you can use the display saved-confi command to display it, and then copy and execute it.

• If the password is stored in plain text, you can use the display current-configuration command to vie

the password in the current configuration. If you use the set authentication password cipher 123456 command to set a password, the password is stored in cipher text.

Step4 Save the new configuration.

[SYSTEM] save

NOTE:

Use the save command to save your new password.

BootWare Password Loss

Contact the agent or the technical support personnel to set a new BootWare password in the event of BootWare password loss.

You can modify the BootWare password under the main BootWare menu.

Enter 5 in the main BootWare menu to modify the password: The console terminal displays:

please input old password: Please input new password: Please input new password again: Password Set Successfully.

uration, but the original configuration file is stored

uration

NOTE:

The password modification fails when the old password is not correct or new password is inconsistent. Then the system will exit this operation.

Super Password Loss

The super password enables you to switch between four super levels. In the event of super password loss, you cannot perform higher level operations.

You can clear the super password by entering 8 in the main BootWare menu.

After you clear the super password, quit the menu and reboot the router, you can directly enter system view. The setting is valid for the first reboot of the router only. The super password will be restored after a second reboot.

Backing Up and Restoring BootWare

Enter 7 under the main BootWare menu to enter the BootWare operation submenu. Refer to “BootWare

operation submenu” on page

Enter 1 under the menu, and the system starts to backup the entire BootWare. The system prompts:

Will you backup the Basic BootWare? [Y/N]Y

Begin to backup the Basic BootWare................................Done!

Will you backup the Extend BootWare? [Y/N]Y

Begin to backup the Extend BootWare................................Done!

Now, the entire BootWare is backed up to the memory.

Enter 2 under the menu to restore the BootWare in the memory to the system:

Will you restore the Basic BootWare? [Y/N]Y

Begin to restore Normal Basic BootWare................................Done!

Will you restore the Extend BootWare? [Y/N]Y

Begin to restore Normal Extend BootWare................................Done!

Solution:

Check that:

• The power switch on the router is turned on

• The switch of the power source is turned on

• The power cord is correctly connected

• The power source meets the requirement of the router

Troubleshooting the Configuration System

If the router passes POST after powered on, the console screen displays the startup banner; if faults occur to the configuration system, the console screen displays nothing or only illegible characters.

Symptom 1:

After the router is powered on, the console screen displays nothing.

Solution:

Step 1: Check that:

• The power system is normal.

• The console cable is correctly connected.

Step 2: Check the console cable and the terminal (HyperTerminal for example) settings.

Symptom 2:

After the router is powered on, the console screen displays illegible characters.

Solution:

Verify that the terminal settings are as follows:

Baud: 9600

Data bits: 8

Stop bit: 1

Parity: None

Flow control: None

Terminal emulation: VT100

Reconfigure the parameters if their values are different.

Troubleshooting Application Software Upgrade

Symptom 1:

When upgrading the software using TFTP/FTP, the system displays:

Solution:

Fault occurs because the source file does not exist, the network cable is not connected, or the IP address of the PC is incorrect. Make sure that the source file is in the TFTP/FTP root directory, the cable is connected securely, and the IP address is set correctly.

Symptom 2:

When upgrading the software using TFTP, the system displays:

Loading... Done! 11487495 bytes downloaded.

NOTE:

Something wrong with the file.
