the function for filtering of DHCP server packet and to add/delete the
DHCP server/client binding entry.

config filter dhcp_server [add permit server_ip <ipaddr>
{ client_mac <macaddr>} ports [ <portlist> | all ] | delete permit
server_ip <ipaddr> { client_mac <macaddr> } {ports <portlist>
state [ enable | disable]}
Description
The
config filter dhcp_server
command has two purposes: To filter
all DHCP server packets on the specified port(s) and to allow some
DHCP server packets to forwarded if they are on the pre-defined

ports <portlist> –
The port number to which the DHCP filter will be
applied.
state –

Example usage:
To add an entry from the DHCP server/client filter list in the Switch’s database:
DGS-1210-28MP/ME:5# config filter dhcp_server add permit server_ip 10.1.1.1
client_mac 00-00-00-00-00-01 ports all
Command: config filter dhcp_server add permit server_ip 10.1.1.1 client_mac 00-00-
