Chapter 1  Boot ROM 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 the Boot ROM and host software to a switch locally and remotely.

When configuring the Boot ROM and host software loading, go to these sections for information you are interested in:

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 high stability. 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.

II. Loading Boot ROM

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

 Upgrading BOOTROM, please wait...

 Upgrade BOOTROM succeeded!

Step 3: Restart the switch.

<Sysname> reboot

 

&  Note:

Before restarting the switch, make sure you have saved all other configurations that you want, so as to avoid losing configuration information.

 

2)         Loading host software

Loading the host software is the same as loading the Boot ROM 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 Boot ROM and host software loading is completed.

Pay attention to the following:

l           The loading of Boot ROM 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. For information about deleting files, refer to File System Management part of this manual.

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 upload the Boot ROM switch.btm to the switch.

1)         Loading the Boot ROM

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 192.168.0.28, and subnet mask to 255.255.255.0.

 

&  Note:

You can configure the IP address for any VLAN on the switch for FTP transmission. However, before configuring the IP address for a VLAN interface, you have to make sure whether the IP addresses of this VLAN and PC are routable.

 

<Sysname> system-view

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

[Sysname] interface Vlan-interface 1

[Sysname-Vlan-interface1] ip address 192.168.0.28 255.255.255.0

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

[Sysname-Vlan-interface1] quit

[Sysname] ftp server enable

[Sysname] local-user test

New local user added.

[Sysname-luser-test] password simple pass

[Sysname-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 Boot ROM 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 Boot ROM directory

Step 6: Enter ftp 192.168.0.28 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 switch.btm to the switch, as shown in Figure 1-13.

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

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

<Sysname> boot bootrom switch.btm

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

 Upgrading Bootrom, please wait...

 Upgrade Bootrom succeeded! 

<Sysname> reboot

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

2)         Loading host software

Loading the host software is the same as loading the Boot ROM 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.

 

&  Note:

l      The steps listed above are performed in the Windows operating system, if you use other FTP client software, refer to the corresponding user guide before operation.

l      Only the configuration steps concerning loading are listed here. For detailed description on the corresponding configuration commands, refer to FTP-SFTP-TFTP part of this manual.

 

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.

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 also be used to help locate the network faults.

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.

To do…

Use the command…

Remarks

View 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.

4.2.6  Upgrading the Boot ROM

You can use the Boot ROM program saved in the Flash memory of the switch to upgrade the running Boot ROM. With this command, a remote user can conveniently upgrade the Boot ROM by uploading the Boot ROM to the switch through FTP and running this command. The Boot ROM can be used when the switch restarts.

Use the following command to upgrade the Boot ROM:

4.2.7  Loading Hot Patch

A patch is a standalone software unit that is released to fix errors found in a system.

A hot patch can fix system errors without rebooting the device or interrupting network operation. That is, it can upgrade the system dynamically.

Patches can be added to a patch file incrementally. That is, any subsequent patch file contains all the patches for fixing errors in the previous patch file besides the patches for fixing the current errors. In this way, all the system errors found can be fixed once and for all by loading the latest patch file.

In the device, a patch can be in one of the following four states:

l           IDLE: The patch is initialized but not loaded.

l           DEACTIVE: The patch is loaded but not activated.

l           ACTIVE: The patch is active but not running.

l           RUNNING: The patch is running.

The difference between active patches and running patches:

l           After system reboot, an ACTIVE patch becomes DEACTIVE and stops working;

l           After system reboot, a running patch remains running.

The active state provides a buffer to help prevent the system from running with errors introduced by the by the patches.

Any state of the four cannot be switched to another without user intervention on the command line.

Figure 4-1 illustrates how patch states change with commands:

Note the following:

1)         Make sure that you set the file transfer mode to binary before you upload a patch file through FTP or TFTP to the flash memory of the device; otherwise, patch file loading will fail.

2)         Before loading a patch file, verify that the baseline version number of the patch file and the current software version number are consistent, and the extension name of a patch file must be .pat by using the display version command. For the baseline version number of the patch file, see the patch file name. Patch files are named in the format of [product name]-[baseline version number]-[patch version number].pat.

3)         The patch delete command deletes all the patches in the device. To prevent the solved system errors from occurring again, you need to reload and activate the related patches.

4)         Patch state information is stored in a file named patchstate in the flash memory. You are not encouraged to perform any operation on this file.

4.2.8  Displaying Pluggable Transceiver Information

At present, three types of pluggable transceivers are commonly used on H3C series Ethernet switches:

l           SFP (Small Form-factor Pluggable): generally used for 100M or 1000M Ethernet interfaces.

l           XFP (10-Gigabit small Form-factor Pluggable): generally used for 10G Ethernet interfaces.

l           XENPAK (10 Gigabit EtherNet Transceiver Package): generally used for 10G Ethernet interfaces.

&  Note:

For pluggable transceivers supported by S3100-52P Ethernet switch, refer to H3C S3100-52P Ethernet Switch  Installation Manual.

 

Transceivers customized by H3C refer to the pluggable transceivers with the Vendor Name field being H3C in the prompt information of the display transceiver interface command.

Transceivers customized by H3C support display of electrical label information. Electrical label information is also called permanent configuration data or archive information, which is written to the storage device of a card during device debugging or test. The information includes name of the card, device serial number, and vendor name or vendor name specified.

Optical transceivers customized by H3C support the digital diagnosis function, which enables a customized optical transceiver to monitor the main parameters such as temperature, voltage, laser bias current, TX power, and RX power.

Use the following commands to display information of pluggable transceivers:

4.4  Remote Switch APP 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 Boot ROM 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.
