Parameters
filename: Specifies the name of a local file. For information about the filename argument, see
Fundamentals Configuration Guide.
url url: Specifies the URL of a remote file. Do not include a username or password in the URL. Case
sensitivity and the supported path format type vary by server.
username username: Specifies the username for logging in to the remote device.
cipher: Sets a ciphertext password.
simple: Sets a plaintext password.
key: Specifies the key string. This argument is case sensitive. If simple is specified, it must be a string of
1 to 32 characters. If cipher is specified, it must be a ciphertext string of 1 to 73 characters.
Usage guidelines
For security purposes, all passwords, including passwords configured in plaintext, are saved in
ciphertext.
This command enables the device to immediately save DHCP snooping entries to the specified database
file. If the file does not exist, the device automatically creates the file. The device does not update the file
for a specific amount of time after a DHCP snooping entry changes. The default period is 300 seconds.
To change the value, use the dhcp snooping binding database update interval command.
When the file is on a remote device, follow these restrictions and guidelines to specify the URL, username,
and password:
• If the file is on an FTP server, enter URL in the following format: ftp://server address:port/file path,
where the port number is optional.
• If the file is on a TFTP server, enter URL in the following format: tftp://server address:port/file path,
where the port number is optional.
• The username and password must be the same as those configured on the FTP or TFTP server. If the
server authenticates only the username, the password can be omitted. For example, enter URL
ftp://1.1.1.1/database.dhcp username admin to specify the URL and username options at the CLI.
