Group or Subnet Table Report
This message reports the current settings of either group or subnet forwarding
tables in EEPROM or RAM for the specified domain for a single router side. The
report function is segmented into eight byte sections.

only. Use of this message with earlier versions of the router firmware cause the
router to become inoperable.
