Traffic is dropped correctly, but post save/reboot, traffic still goes through. 
Need to unbind/bind the acl again to make the traffic drop again.

#config save -y
#reboot

Workaround to make it work(Remove the acl and install again)

root@sonic:~# cat clear_acl.json
{
    "ACL_TABLE": {
    },
    "ACL_RULE": {
    }
}
root@sonic:~# config load clear_acl.json -y
