Filter DHCP Server The Dynamic Host Configuration Protocol (DHCP) automates the assignment of IP addresses, subnet masks, default routers, and other IP parameters. The assignment usually occurs when the DHCP configured machine boots up or regains connectivity to the network. The DHCP client sends out a query requesting a response from a DHCP server on the locally attached network. The DHCP server then replies to the client with its assigned IP address, subnet mask, DNS server and default gateway information. This function allows DHCP server packets except those that have been IP/client MAC bound to be filtered. The DHCP Server Screening is used to configure the state of the function for filtering of DHCP server packets and to add or delete the DHCP server/client binding entry. This command has two purposes firstly to filter all DHCP server packets on the specified port(s) and secondly to allow some DHCP server packets to be forwarded if they are on the pre-defined server IP address/MAC address binding list. Thus the DHCP server can be restricted to service a specified DHCP client. This is useful when there are two or more DHCP servers present on a network.
