Release Information

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

Support at the [edit ethernet-switching-options secure-access-port dhcpv6-snooping-file] hierarchy level introduced in Junos OS Release 14.1X53-D10 for EX Series switches.

Description

Configure IP-MAC address 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 snooping 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 snooping 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.
