Chapter 1  BootROM and Host Software Loading

Traditionally, switch software is loaded through a serial port. This approach is slow, time-consuming and cannot be used for remote loading. To resolve these problems, the TFTP and FTP modules are introduced into the switch. With these modules, you can load/download software/files conveniently to the switch through an Ethernet port.

This chapter introduces how to load BootROM and host software to a switch locally and remotely.

1.1  Introduction to Loading Approaches

You can load software locally by using:

l           XModem through Console port

l           TFTP through Ethernet port

l           FTP through Ethernet port

You can load software remotely by using:

l           FTP

l           TFTP

 

 

1.2  Local BootROM and Software Loading

If your terminal is directly connected to the switch, you can load the BootROM and host software locally.

Before loading the software, make sure that your terminal is correctly connected to the switch.

1.2.2  Loading by XModem through Console Port

I. Introduction to XModem

XModem protocol is a file transfer protocol that is widely used due to its simplicity and good performance. The XModem protocol transfers files through Console port. It supports two types of data packets (128 bytes and 1 KB), two check methods (checksum and CRC), and multiple attempts of error packet retransmission (generally the maximum number of retransmission attempts is ten).

The XModem transmission procedure is completed by a receiving program and a sending program. The receiving program sends negotiation characters to negotiate a packet checking method. After the negotiation, the sending program starts to transmit data packets. When receiving a complete packet, the receiving program checks the packet using the agreed method. If the check succeeds, the receiving program sends acknowledgement characters and the sending program proceeds to send another packet. If the check fails, the receiving program sends negative acknowledgement characters and the sending program retransmits the packet.

[ftp] get S3600.btm

[ftp] bye

 

 

Step 2: Update the BootROM program on the switch.

<H3C> boot bootrom S3600.btm

 This will update BootRom file on unit 1. Continue? [Y/N] y

 Upgrading BOOTROM, please wait...

 Upgrade BOOTROM succeeded!

Step 3: Restart the switch.

<H3C> reboot

 

 

2)         Loading host software

Loading the host software is the same as loading the BootROM program, except that the file to be downloaded is the host software file, and that you need to use the boot boot-loader command to select the host software used for next startup of the switch.

After the above operations, the BootROM and host software loading is completed.

Pay attention to the following:

l           The loading of BootROM and host software takes effect only after you restart the switch with the reboot command.

l           If the space of the Flash memory is not enough, you can delete the unused files in the Flash memory before software downloading.

l           Ensure the power supply during software loading.

II. Loading Procedure Using FTP Server

As shown in Figure 1-9, the switch is used as the FTP server. You can telnet to the switch, and then execute the FTP commands to download the BootROM program S3600.btm from the switch.

1)         Loading BootROM

Figure 1-9 Remote loading using FTP server

Step 1: As shown in Figure 1-9, connect the switch through an Ethernet port to the PC (whose IP address is 10.1.1.1)

Step 2: Configure the IP address of VLAN-interface 1 on the switch to 192.168.0.39, and subnet mask to 255.255.255.0.

 

 

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] interface Vlan-interface 1

[H3C-Vlan-interface1] ip address 192.168.0.39 255.255.255.0

Step 3: Enable FTP service on the switch, and configure the FTP user name to test and password to pass.

[H3C-Vlan-interface1] quit

[H3C] ftp server enable

[H3C] local-user test

New local user added.

[H3C-luser-test] password simple pass

[H3C-luser-test] service-type ftp

Step 4: Enable FTP client software on the PC. Refer to Figure 1-10 for the command line interface in Windows operating system.

Figure 1-10 Command line interface

Step 5: Use the cd command on the interface to enter the path that the BootROM upgrade file is to be stored. Assume the name of the path is D:\Bootrom, as shown in Figure 1-11.

Figure 1-11 Enter BootROM directory

Step 6: Enter ftp 192.168.0.39 and enter the user name test, password pass, as shown in Figure 1-12, to log on to the FTP server.

Figure 1-12 Log on to the FTP server

Step 7: Use the put command to upload the file S3600.btm to the switch, as shown in Figure 1-13.

Figure 1-13 Upload file S3600.btm to the switch

Step 8: Configure S3600.btm to be the BootROM at next startup, and then restart the switch.

<H3C> boot bootrom S3600.btm

 This will update Bootrom on unit 1.  Continue? [Y/N] y

 Upgrading Bootrom, please wait...

 Upgrade Bootrom succeeded! 

<H3C> reboot

After the switch restarts, the file S3600.btm is used as the BootROM. It indicates that the BootROM loading is finished.

2)         Loading host software

Loading the host software is the same as loading the BootROM program, except that the file to be downloaded is the host software file, and that you need to use the boot boot-loader command to select the host software used for the next startup of the switch.

 

 

1.3.2  Remote Loading Using TFTP

The remote loading using TFTP is similar to that using FTP. The only difference is that TFTP is used to load software to the switch, and the switch can only act as a TFTP client.

2.3  Debugging the System

2.3.1  Enabling/Disabling System Debugging

The Ethernet switch provides a variety of debugging functions. Most of the protocols and features supported by the Ethernet switch are provided with corresponding debugging functions. These debugging functions help users diagnose and troubleshoot the system faults.

The output of debugging information is determined by the following two settings:

l           Protocol debugging setting, which controls whether the debugging information of a protocol is output.

l           Terminal display setting, which controls whether the debugging information is output to the screen of a specific user.

The relationship between the two settings is as follows:

Figure 2-1 Debugging information output

You can use the following commands to perform the settings.

Table 2-11 Enable debugging and terminal display

Operation	Command	Description
Enable system debugging for specific module	debugging module-name [ debugging-option ]	By default, all debugging is disabled in the system. Because the output of debugging information will affect the efficiency of the system, disable your debugging after you finish it.
Enable terminal display for debugging	terminal debugging	By default, terminal display for debugging is disabled.

 

2.3.2  Displaying Debugging Status

Table 2-12 Display the current debugging status in the system

Operation	Command	Description
Display all enabled debugging on the specified device	display debugging { fabric | unit unit-id } [ interface interface-type interface-number | module-name ]	You can execute the display command in any view.
Display all enabled debugging in the Fabric by module	display debugging fabric by-module

 

2.3.3  Displaying Operating Information about Modules in System

When an Ethernet switch is in trouble, you may need to view a lot of operating information to locate the problem. Each functional module has its corresponding operating information display command(s). You can use the command here to display the current operating information about the modules in the system for troubleshooting your system.

Table 2-13 Display the current operation information about the modules in the system.

Operation	Command	Description
Display the current operation information about the modules in the system.	display diagnostic-information	You can use this command in any view. You should execute this command twice to find the difference between the two executing results, thus helping locate the problem.

 

Chapter 3  Network Connectivity Test

3.1  Network Connectivity Test

3.1.1  ping

You can use the ping command to check the network connectivity and the reachability of a host.

Table 3-1 The ping command

Operation	Command	Description
Check the IP network connectivity and the reachability of a host	ping [ -a ip-address ] [-c count ] [ -d ] [ -f ] [ -h ttl ] [ -i interface-type interface-number ] [ ip ] [ -n ] [ - p pattern ] [ -q ] [ -s packetsize ] [ -t timeout ] [ -tos tos ] [ -v ] host	You can use this command in any view.

 

This command can output the following results:

l           Response status for each ping packet. If no response packet is received within the timeout time, the message "Request time out" is displayed. Otherwise, the number of data bytes, packet serial number, TTL (time to live) and response time of the response packet are displayed.

l           Final statistics, including the numbers of sent packets and received response packets, the irresponsive packet percentage, and the minimum, average and maximum values of response time.

3.1.2  tracert

You can use the tracert command to trace the gateways that a packet passes from the source to the destination. This command is mainly used to check the network connectivity. It can help locate the trouble spot of the network.

The executing procedure of the tracert command is as follows: First, the source host sends a data packet with the TTL of 1, and the first hop device returns an ICMP error message indicating that it cannot forward this packet because of TTL timeout. Then, the source host resends the packet with the TTL of 2, and the second hop device also returns an ICMP TTL timeout message. This procedure goes on and on until the packet gets to the destination. During the procedure, the system records the source address of each ICMP TTL timeout message in order to offer the path that the packet passed through to the destination.

Table 3-2 The tracert command

Operation	Command	Description
Trace the gateways that a packet passes from the source host to the destination	tracert [ -a source-ip ] [ -f first-ttl ] [ -m max-ttl ] [ -p port ] [ -q num-packet ] [ -w timeout ] string	You can execute the tracert command in any view.

4.4  Remote Switch Upgrade Configuration Example

I. Network requirements

Telnet to the switch from a PC remotely and download applications from the FTP server to the Flash memory of the switch. Update the switch software by using the device management commands through CLI.

The switch acts as the FTP client, and the remote PC serves as both the configuration PC and the FTP server.

Perform the following configuration on the FTP server.

l           Configure an FTP user, whose name is switch and password is hello. Authorize the user with the read-write right on the directory switch on the PC.

l           Make configuration so that the IP address of a VLAN interface on the switch is 1.1.1.1, the IP address of the PC is 2.2.2.2, and the switch and the PC is reachable to each other.

The host software switch.bin and the BootROM file boot.btm of the switch are stored in the directory switch on the PC. Use FTP to download the switch.bin and boot.btm files from the FTP server to the switch.
