Release Information

Statement introduced in Junos OS Release 9.4 for EX Series switches.

Description

Configure IP-MAC bindings to persist through switch reboots by specifying a location in which to store the DHCP snooping database. When specifying the location for the DHCP database, you must also specify how frequently the switch writes (write-interval) the database entries into the DHCP snooping database file.

If you choose to store the DHCP database on a remote FTP site, you might want to specify the time (timeout) that the switch waits for a remote system to respond when the DHCP snooping database is stored on a remote FTP site. This is optional.

Options

local_pathname | remote_url

local_pathname —Use /path to store the database file on the local switch.
remote_url —Use ftp://ip-address or ftp:// hostname/path to store the database on a remote FTP site.
