That's an extremely misleading bit of text that I had a very grumpy 
conversation with Juniper about.

You can indeed apply the firewall filters to IPv6 traffic. But you can't 
specify any IPv6 protocols fields as matches.

So w00t a default deny or ethertype deny will apply to IPv6 as opposed 
to skipping it entirely.

EX3300 apparently has no IPv6 field matching capability in hardware. 
Which is almost unbelievable for a current-gen switch, but that's what 
Juniper told us, repeatedly.
