This read-write object sets a group disposition for GARP frames using the reserved MAC address range 01:80:C2:00:00:22 through 01:80:C2:00:00:2F on this Ethernet traffic port. An administrator configures this to apply one treatment to whichever less-common GARP application protocols fall in that reserved range rather than configuring each individually. For example, setting this disposition to discard would block any GARP variant using an address in that range that has no dedicated disposition object of its own.
