FTP Session

This chapter discusses the Cisco ONS 15216 EDFA3 FTP command line and explains how to get and send image and configuration files between an FTP server and the ONS 15216 EDFA3.

FTP (File Transfer Protocol) is a client/server protocol for sharing files between machines over a TCP/IP network. The local machine runs an FTP client. The remote machine contains an FTP server that must be connected to before exchanging files between the two machines.

A typical FTP session consists of:

• Logging into an FTP Session

• Getting a File

• Logging Out of an FTP Session

• FTP Commands

11.1  Logging into an FTP Session

To start an FTP session, use the following command:

> ftp server_IP_address

for example, type:

> ftp 100.110.120.100

where 100.110.120.100 is the IP address of the host.

When the connection is made, a read/write/administration (RWA) user can log in with the user name and password. When you are connected to the FTP host, you can list files using the dir command. This lists files and directories on the remote server. If no filenames are specified, dir lists all files in the current directory.

11.2  Getting a File

Because the file to be retrieved is not a text file, use binary mode to transfer the file. Use the bin command to indicate that this is a binary file transfer.

The get command downloads a single file. An example of the get command is:

get remote-file local-file

where remote-file is the file that you want to retrieve and local-file (optional) is the name for the file on your file system. The get command copies the remote file from the remote server to the local machine. If a local file filename is specified, the downloaded file uses this name. If the local file name is omitted, the file is copied to the local default directory with the same name.

11.3  Logging Out of an FTP Session

To log off an FTP session, type quit, bye, or disconnect at the FTP command line. Any of these commands disconnects the user from the remote server and exits the FTP shell.

11.4  FTP Commands

Typing the help or ? command in FTP command line mode displays a list of all FTP commands. See Example 11-1.

Example 11-1 FTP Help Command

ftp> ?
Commands may be abbreviated. Commands are:

! delete literal prompt send
? debug ls put status
append dir mdelete pwd trace
ascii disconnect mdir quit type
bell get mget quote user
binary glob mkdir recv verbose
bye hash mls remotehelp
cd help mput rename
close lcd open rmdir

For help on specific commands, use help or ? followed by the command name, as shown in Example 11-2.

Example 11-2 Help on Specific Command

ftp> ? put
put send one file

ftp> help get
get receive file

Note The EDFA3 FTP Server does not support wildcard (*) commands, multiple file send/receive commands (mget, mput, etc.), or mkdir/rmdir and rename commands.

Note The user can use the delete command instead of rmdir to delete a directory.
