DHCP Binding Database

DHCP server reply packets are forwarded to DHCP clients on trusted ports. The DHCP server reply packets collect client IP-to-MAC address binding information, which is saved in the DHCP binding database. This information includes MAC addresses, IP addresses, lease time, VLAN numbers, and port numbers.

Beginning with FastIron 8.0.30b, the DHCP binding database in the RUCKUS device is decoupled from the ARP database. For more information, refer to ARP and DHCP snoop entries.

The lease time is refreshed when the client renews or rebinds its IP address with the DHCP server; otherwise, the RUCKUS device removes the entry when the lease time expires.
