Data point, although the chances of you using this kit in an IX are slim 
to none: The HPE-badged H3C workgroup switches are problematic to 
configure this for.

1) The web GUI is woefully unable to do it right, and HP do not 
officially sanction the use of the CLI.

2) IPv6 packet ACLs only appear to be supported per-port on *ingress*.
