Configuring DHCP Filter DHCPv4 Filter Configuration
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.
The following example shows how to enable DHCPv4 Filter globally and how to enable
DHCPv4 Filter, enable the MAC verify feature, set the limit rate as 10 pps and set the
decline rate as 20 pps on port 1/0/1:
Switch#configure
Switch(config)#ip dhcp filter
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#ip dhcp filter
Switch(config-if)#ip dhcp filter mac-verify
Switch(config-if)#ip dhcp filter limit rate 10
Switch(config-if)#ip dhcp filter decline rate 20
Switch(config-if)##show ip dhcp filter
Global Status: Enable
Switch(config-if)#show ip dhcp filter interface gigabitEthernet 1/0/1
Interface state MAC-Verify Limit-Rate Dec-rate LAG
--------- ------- ---------- ---------- -------- ---
Gi1/0/1 Enable Enable 10 20 N/A
