[j-nsp] EX3300 family ethernet-switching IPv6 matches?

[Phil Mayers]

All,

The release notes for the EX3300 are a little vague on this, but 
strongly imply that as of Junos 12.3, IPv6 firewall filters are 
supported. However:

[edit firewall family ethernet-switching filter FPP term deny-ra]
admin at sh-299y# set from ip-version ?
Possible completions:
+ apply-groups         Groups from which to inherit configuration data
+ apply-groups-except  Don't inherit configuration data from these groups
 > ipv4                 Define L3/L4 match items to match IPv4 packets

Note: no IPv6.

I can match on the IPv6 ether-type, but not any L3/L4 items:

[edit firewall family ethernet-switching filter FPP term deny-ra from]
   'protocol'
     ipv4 match item not allowed when ether-type is ipv6
[edit firewall family ethernet-switching filter FPP term deny-ra from]
   'icmp-type'
     ipv4 match item not allowed when ether-type is ipv6

Is this expected to work? Or is the "ipv6 support" for routed packets 
only, and not for ethernet-switching?
