Why I did it Need to enable DHCPv6 COPP rules. How I did it Load the separate DHCPv6 COPP rules after warm reboot if the rules are missing. How to verify it Warm reboot from an image doesn't have DHCPv6 COPP rules installed. Warm reboot from an image have DHCPv6 COPP rules already installed. In either case, the script did the right thing and only install the COPP rules if it is missing. Signed-off-by: Ying Xie ying.xie@microsoft.com
