IPv6 usage

It appears the JunOS is able to break out the amount of IPv6 (https://www.juniper.net/documentation/en_US/junos16.1/topics/reference/comma...) on an interface. Does the EX4200 also support the IP MIB (https://tools.ietf.org/html/rfc4293#section-3.2.3)? If so, it would be great to graph the amount and percentage of IPv6 traffic on most, if not all, interfaces. Frank
