Accessing Other Devices Configuration

Overview of Accessing Other Devices

You can log in to one device and access another device using Telnet, FTP, TFTP or SFTP.

Configuration Precautions for Accessing Other Devices

Using Telnet to Log In to Other Devices

Telnet is a client/server application that allows you to log in to remote devices to manage and maintain the devices.

Using STelnet to Log In to Other Devices

STelnet provides secure Telnet services. You can use STelnet to log in to and manage other devices from the device that you have logged in to.

Using TFTP to Access Other Devices

TFTP is used to transfer files between remote servers and local hosts. Unlike FTP, TFTP is simple and provides no authentication. TFTP applies when no complex interaction is required between clients and the server.

Using FTP to Access Other Devices

You can log in to an FTP server from the device that functions as an FTP client to upload files to or download files from the server.

Using SFTP to Access Other Devices

SFTP provides secure FTP services. After a device is configured as an SFTP client, the SFTP server authenticates the client and encrypts data in both directions to provide secure file transfer.

Configuring the SFTP Client to Use the One-click File Operation Command to Perform File Operations

The device functions as an SFTP client and uses the one-click file operation command to upload files from the SFTP client to the SFTP server or download files from the SFTP server to the SFTP client.

Using SCP to Access Other Devices

The Secure Copy Protocol (SCP) client sets up a secure connection to the SCP server so that the client can upload files to or download files from the server.

Configuring an SSL Cipher Suite

During authentication between the client and server, a cipher list is provided for SSL algorithm negotiation. This section describes how to configure a cipher list for an SSL cipher suite. Using a cipher list enhances system security.

Configuring and Binding an SSL Policy

SSL policies can be used to protect transmitted data from being tampered with, improving security.

Logging In to a Device Using HTTP

Hypertext Transfer Protocol (HTTP) is an application-layer protocol that transports hypertext from WWW servers to local browsers. HTTP uses the client/server model in which requests and replies are exchanged.

Configuring a DSCP Value for Telnet/SSH Packets

This section describes how to configure a DSCP value for Telnet/SSH packets.
