Things I learned from Ascend support [Thanks Ascend!] included:

  + There can be at most one "bind" statement per direction that the
    filter is being applied.  I incorrectly thought they were all
    merged together.

  + If you are applying a filter to multiple interfaces, you have to
    do it in a single "bind" statement by specifying all the interface
    numbers.

We currently have been using filters on our HSSI ports.  Substitute
the appropriate device type name below and interface as needed.

# Bind the Internet Filters
media hssi 2 {
  bind inbound_filter {
    vlif 0;
    direction in;
    action filter;
  }

  bind outbound_filter {
    vlif 0;
    direction out;
    action filter;
  }
}

I found the best way to work with Ascend support, was to outline
in text, what the purpose of each filter is and how it's supposed
to work.  I then showed them the filters I thought would do this.
The feedback was very useful in understanding nuances of how to
properly code the filter file.
