DHCP server/client binding entry.
Syntax
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
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 f network.
Parameters
<ipaddr> – The IP address of the DHCP server to be filtered
client_mac <macaddr> – The MAC address of the DHCP client.
ports <portlist> – The port number to which the DHCP filter will be
applied.
state – Enable/Disable the DHCP filter state.
Restrictions
Only administrator or operate-level users can issue this command.
Example usage:
To add an entry from the DHCP server/client filter list in the Switch’s database:
DES-1210-52/ME:5# config filter dhcp_server add permit server_ip
10.1.1.1 client_mac 00-00-00-00-00-01 ports 6-8
Command: config filter dhcp_server add permit server_ip 10.1.1.1
