Configuring DHCP Filter DHCPv6 Filter Configuration
Step 10 copy running-config startup-config
Save the settings in the configuration file.
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 DHCPv6 Filter globally and how to enable 
DHCPv6 Filter,  set the limit rate as 10 pps and set the decline rate as 20 pps on port 1/0/1:
Switch#configure
Switch(config)#ipv6 dhcp filter
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#ipv6 dhcp filter
Switch(config-if)#ipv6 dhcp filter limit rate 10
Switch(config-if)#ipv6 dhcp filter decline rate 20
Switch(config-if)##show ipv6 dhcp filter
Global Status: Enable
Switch(config-if)#show ip dhcp filter interface gigabitEthernet 1/0/1
Interface     state            Limit-Rate      Dec-rate      LAG
