ftp://[username[:password@]]host[/filedir]/
■
ftp:// – Defines FTP protocol for the server connection.
■
username – Defines the user name for the FTP connection. If the
user name is omitted, then “anonymous” is the assumed user name
for the connection.
■
password – Defines the password for the FTP connection. To
differentiate the password from the user name and host portions of
the URL, a colon (:) must precede the password, and an “at” symbol
(@), must follow the password. If the password is omitted, then “”
(an empty string) is the assumed password for the connection.
■
host – Defines the IP address of the FTP server. Valid IP addresses
consist of four numbers, 0 to 255, separated by periods. DNS host
names are not recognized.
■
filedir – Defines the directory, relative to the FTP server root, where
the upgrade file can be found. Nested directory structures are
accepted. The directory name must be separated from the host, and
in nested directory structures, from the parent directory, with a
prepended forward slash “/”.
■
/ – The forward slash must be the last character of the URL.
Examples
The following examples demonstrate the URL syntax for a TFTP server
at IP address 192.168.0.1 with the operation code image stored in
various locations:
■
tftp://192.168.0.1/
The image file is in the TFTP root directory.
■
tftp://192.168.0.1/switch-opcode/
The image file is in the “switch-opcode” directory, relative to the
TFTP root.
■
tftp://192.168.0.1/switches/opcode/
The image file is in the “opcode” directory, which is within the
“switches” parent directory, relative to the TFTP root.
The following examples demonstrate the URL syntax for an FTP server
at IP address 192.168.0.1 with various user name, password and file
location options presented:
■
ftp://192.168.0.1/
The user name and password are empty, so “anonymous” will be
the user name and the password will be blank. The image file is in
the FTP root directory.
■
ftp://switches:upgrade@192.168.0.1/
The user name is “switches” and the password is “upgrade”. The
image file is in the FTP root.
