Usage Guidelines

This commands allows you to add a DHCP binding in order to re-create the bindings after reboot and to allow IP Security features to work with clients having static IP addresses.

Note

Note

Setting the lease-time to 0 causes the DHCP binding to be static; in other words, it is not aged-out if no DHCP renew occurs. This is for use with clients using static IP addresses.
