This object is used to enable and disable jumbo frames. This object does not support binding and issuance of the entire table. When the carriers' servers need to exchange a large amount of data with their devices, operate this object to enable jumbo frames. After the operation is executed successfully, the corresponding port on the control board can transparently transmit the frames whose size is between 1600 bytes and 9216 bytes. By default, the ports disable jumbo frames. Options: 1. invalid(-1) -invalid 2. enabled(1) -enable the jumbo frames 3. disabled(2) -disable the jumbo frames Default: disable(2)
