The allowed maximum frame size is 10236 bytes on non-line-speed XP4 boards
and LSB1GV48 boards and 10240 bytes on other GE and 10GE boards.

You can configure the jumbo frame size in the range 1552 to 10240 in bytes.
However, if the size is set in the range 1553 to 9022, the value 9022 takes effect; if
the size is set in the range 9023 to 9192, the value 9192 takes effect; if the size is set
in the range 9193 to 10240, 10240 takes effect.
1.1.11 Configuring the MDI Mode of an Ethernet Interface
You can connect an Ethernet interface with a crossover or straight-through cable,
depending on its medium dependent interface (MDI) mode. The MDI mode can be one
of the following:
z
Across mode, where the Ethernet interface can be connected only to a crossover
cable.
z
Normal mode, where the Ethernet interface can be connected only to a
straight-through cable.
z
Auto mode, where the Ethernet interface can be connected to either a
straight-through cable or a crossover cable.
Use the auto mode in normal cases. In case the interface in auto mode cannot
recognize the type of the connected cable, set its MDI mode to across or normal.
Follow these steps to configure the MDI mode of an Ethernet Interface:
