HP MSR2000/3000/4000 Router Series Layer 3 - IP Services Command Reference

81
url url: Specifies the URL of a remote file. Do not contain a username or password in the URL.
Case-sensitivity of the URL and the supported path format type depend on the 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, following these 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.
• If the IP address of the server is an IPv6 address, enclose the address in a pair of brackets, for
example, ftp://[1::1]/database.dhcp.
• You can also specify the DNS domain name for the server address field, for example,
ftp://company/database.dhcp.
Examples
# Specify the file database.dhcp to store DHCP snooping entries.
<Sysname> system-view
[Sysname] dhcp snooping binding database filename database.dhcp
# Save DHCP snooping entries to file database.dhcp i n t h e w o r k i n g d i r e c t o r y o f t h e F T P s e r ve r a t 10 .1.1.1
with both the username and password being 1.

[Sysname] dhcp snooping binding database filename url ftp://10.1.1.1/database.dhcp
username 1 password simple 1
# Save DHCP snooping entries to file database.dhcp in the working directory of the TFTP server at
10 .1.1.1.
