Chapter 1  File System Management Configuration

1.1  File Attribute Configuration

1.1.1  Introduction to File Attributes

An app file is an executable file, with .bin as the extension. A configuration file is used to store and restore configuration, with .cfg as the extension. A Web file is used for Web-based network management, with .web as the extension.

The app file, configuration file, and Web file have three kinds of attributes: main, backup and none, as described in Table 1-1.

Table 1-1 Descriptions on file attributes

Attribute name	Description	Feature	Identifier
main	Identifies main startup files. The main startup file is used first for a switch to start up.	In the Flash memory, there can be only one app file, one configuration file and one Web file with the main attribute.	(*)
backup	Identifies backup startup files. The backup startup file is used after a switch fails to start up using the main startup file.	In the Flash memory, there can be only one app file, one configuration file and one Web file with the backup attribute.	(b)
none	Identifies files that are neither of main attribute nor backup attribute.	—	None

 

 

If a newly created file is configured to be with the main attribute, the existing file with the main attribute in the Flash memory will be changed to other attribute. This ensures that there can be only one app file, one configuration file and one Web file with the main attribute in the Flash memory. This circumstance also applies to the file with the backup attribute in the Flash memory.

File operations and file attribute operations are independent. For example, if you delete a file with the main attribute from the Flash memory, the other files in the flash memory will not possess the main attribute. If you download a file with the same name as the original file with the main attribute to the flash memory, the file will possess the main attribute.

After the BootROM of a switch is upgraded, the original default APP startup file has the main attribute.

1.1.2  Configuring File Attributes

You can configure and view the main attribute or backup attribute of the startup file used for the next startup of a switch, and change the main or backup attribute of the file.

Perform the configuration listed in Table 1-2 in user view. The display commands can be executed in any view.

Table 1-2 Configure file attributes

1.2  File System Configuration

1.2.1  Introduction to File System

To facilitate management on the Flash memory, Ethernet switches provide the file system module. The file system allows users to create/delete a directory, display the current work directory, display the contents of a directory, and access files.

By default, a switch prompts for confirmation before executing the commands which have potential risks (for example, deleting and overwriting files).

1.3  Configuration File Backup and Restoration

Formerly, you can only back up and restore the configuration file of the units one by one in a fabric system.

By using the configuration backup and restoration feature, you can easily back up and restore the configuration files in the whole fabric as well as in a specific unit.

In the backup process, the system first saves the current configuration of a unit to the startup configuration file, and then uploads the file to the TFTP server. In the restore process, the system downloads the startup configuration file from the TFTP server to the local unit.

The configurations of different units in the fabric system can be saved in different .cfg configuration files on the TFTP server. These configuration files correspond to different unit IDs.

1.3.1  Operation Prerequisites

Before performing the following operations, you must first ensure that:

l           The relevant units support TFTP client.

l           The TFTP server is started and reachable.

1.3.2  Operation Procedure

Perform the following operations in user view.

Table 1-8 Back up and restore configuration file

To do…	Use the command…	Remarks
Back up the current configuration of a specified unit	backup unit unit-id current-configuration to { dest-addr | dest-hostname } filename.cfg	Optional
Back up the current configuration of the whole fabric system	backup fabric current-configuration to { dest-addr | dest-hostname } filename.cfg	Optional
Restore the startup configuration of a specified unit	restore unit unit-id startup-configuration from { source-addr | source-hostname } filename.cfg	Optional
Restore the startup configuration of the whole fabric system	restore fabric startup-configuration from { source-addr | source-hostname } filename.cfg	Optional

 

Chapter 2  FTP/TFTP Lighting Configuration

2.1  FTP Lighting Configuration

2.1.1  Introduction to FTP

File transfer protocol (FTP) is a commonly used protocol to transfer files over the Internet and IP networks. Before the emergence of World Wide Web (WWW), users transfer files with command lines mostly using the FTP.

FTP is an application-layer protocol in the TCP/IP protocol suite. It is used for file transfer between remote server and local host.

The Ethernet switch provides the following FTP services:

l           FTP server: A user runs FTP client on a PC and logs into an FTP server (the network administrator should configure the IP address of the FTP server before the user log in). Then the user can access the files on the FTP server.

l           FTP client: A user runs a terminal emulation program or Telnet program on a PC and connects to the Ethernet switch which acts as an FTP client. After that, the user enter the ftp X.X.X.X command (where, X.X.X.X represents the IP address of an FTP server) to establish a connection between the Ethernet switch and a remote FTP server. Then, the user can access the files on the remote FTP server.

2.1.2  FTP Lighting Procedure

 

 

I. Enabling FTP server on the switch

After FTP server is enabled on an S3600 switch, the seven-segment digital LED on the front panel of the switch will rotate clockwise when an FTP client is uploading file to the FTP server (the S3600 switch), and will stop rotating when the file uploading is finished, as show in Figure 2-1.

Figure 2-1 Clockwise rotating of the seven-segment digital LED

Table 2-1 Configuration for file upload from an FTP client to the switch acting as FTP server

Device	To do…	Use the command…	Remarks
FTP server (S3600)	Enable FTP server	ftp sever enable	Required By default, FTP server is disabled.
	Add a local user and enter local user view	local-user user-name	Required
	Set a password for the local user	password { simple | cipher } password	Required
	Set the password display mode for local users	local-user password-display-mode { auto | cipher-force }	Optional By default, the mode is auto (that is, the switch displays user passwords in the modes configured when the passwords are set).
FTP client	Log into the remote FTP server	—	Required For detailed configuration, refer to the configuration instruction relevant to FTP client.
	Upload file from the FTP client to the FTP server	—	Required For detailed configuration, refer to the configuration instruction relevant to FTP client.

 

II. Enabling FTP client on the switch

After FTP client is enabled on an S3600 switch, the seven-segment digital LED on the front panel of the switch will rotate clockwise when the FTP client (the S3600 switch) is downloading file from an FTP server, and will stop rotating when the file downloading is finished, as show in Figure 2-1.

Table 2-2 Configuration for file download from an FTP server to the switch acting as an FTP client

Device	To do…		Use the command…	Remarks
FTP server		Enable FTP server	—	Required For detailed configuration, refer to the configuration instruction relevant to FTP server.
		Configure authentication/authorization of the FTP server	—	Required For detailed configuration, refer to the configuration instruction relevant to FTP server.
FTP client		Log into the remote FTP server	ftp [ ipaddress [ port ] ]	Required l      The switch acts as an FTP client by default. l      The user should first obtain an FTP user name and password, then log into the remote FTP server. Only after that, can the user obtain the access rights of corresponding directory and file. l      When the user logs into the FTP server, the switch enters FTP client command view.
		Download files from the remote FTP server and save the files to the local device	get remotefile [ localfile ]	Required If no local file name is specified, the system will save the file from the remote FTP server to the local device using the original file name.

 

2.2  TFTP Lighting Configuration

2.2.1  Introduction to TFTP

Compared with FTP, trivial file transfer protocol (TFTP) does not provide complex interactive access interface and authentication control, and is suitable for the environments that do not need complex interaction. TFTP is implemented based on user datagram protocol (UDP).

The TFTP file transfer is initiated by a client in the following scenarios:

l           When a file needs to be downloaded, the client sends a read request to the TFTP server. It then receives data from the server and sends acknowledgement to the server.

l           When a file needs to be uploaded, the client sends a write request to the TFTP server. It then sends data to the server and receives acknowledgement from the server.

TFTP can transfer files in two formats:

l           Binary: used to transfer programs.

l           ASCII code: used to transfer text files.

Before configuring TFTP, the network administrator should first configure the IP addresses of the TFTP client and server and ensure that the client and the server are reachable to each other.

The switch can only act as a TFTP client.

Figure 2-2 Network diagram for TFTP configuration

2.2.2  TFTP Lighting Procedure

 

 

After TFTP client is enabled on an S3600 switch, the seven-segment digital LED on the front panel of the switch will rotate clockwise when the TFTP client (the S3600 switch) is downloading file from a TFTP server, and will stop rotating when the file downloading is finished, as show in Figure 2-1.

Table 2-3 Download file from an TFTP server to the switch acting as an TFTP client

Device	To do…	Use the command…	Remarks
TFTP server	Enable TFTP server	—	Required For detailed configuration, refer to the configuration instruction relevant to TFTP server.
TFTP client	Log into a remote TFTP server, download and save a remote file to the local device	tftp tftp-server get source-file [ dest-file ]	Required This command should be executed in user view.
