Switch(config)#ipv6 dhcp snooping vlan 5
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#ipv6 dhcp snooping max-entries 100
Switch(config-if)#show ipv6 dhcp snooping
Global Status: Enable
VLAN ID: 5
Switch(config-if)#show ipv6 dhcp snooping interface gigabitEthernet 1/0/1
Interface max-entries LAG
--------- -----------
Gi1/0/1
100
Switch(config-if)#end
Switch#copy running-config startup-config
