Configuring DHCP Filter DHCPv4 Filter Configuration
Port Displays the port number.
Status Enable or disable DHCPv4 Filter feature on the port.
MAC Verify Enable or disable the MAC Verify feature. There are two fields in the DHCPv4
packet that contain the MAC address of the host. The MAC Verify feature
compares the two fields of a DHCPv4 packet and discards the packet if the two
fields are different.
This prevents the IP address resource on the DHCPv4 server from being
exhausted by forged MAC addresses.
Rate Limit Select to enable the rate limit feature and specify the maximum number of
DHCPv4 packets that can be forwarded on the port per second. The excessive
DHCPv4 packets will be discarded.
Decline Protect Select to enable the decline protect feature and specify the maximum number
of Decline packets that can be forwarded on the port per second. The excessive
Decline packets will be discarded.
LAG Displays the LAG that the port is in.
3) Click Apply.
Note:
The member port of an LAG (Link Aggregation Group) follows the configuration of the LAG and not its
own. The configurations of the port can take effect only after it leaves the LAG.
