IP DHCP SNOOPING DATABASE

ip dhcp snooping database
Overview Use this command to set the location of the file to which the dynamic entries in the
DHCP snooping database are written. This file provides a backup for the DHCP
snooping database.
Use the no variant of this command to set the database location back to the
default, nvs.
ip dhcp snooping database {nvs|flash|usb}
Syntax
no ip dhcp snooping database
Default nvs
Mode Global Configuration
Usage In a stack, the backup file is automatically synchronized across all stack members
to the location configured. If the backup file is stored on a USB storage device on
the stack master, it is only synchronized across stack members that also have USB
storage devices installed.
If the location of the backup file is changed by using this command, a new file is
created in the new location, and the old version of the file remains in the old
location. This can be removed if necessary (hidden file: .dhcp.dsn.gz).
Example To set the location of the DHCP snooping database to Flash memory, use the
commands:
awplus#
awplus(config)#
