10-Gigabit Ethernet using DAC breakout cables (DACBO). When configured for
channelization, a breakout cable converts the 40-Gigabit Ethernet port into 4
independent 10-Gigabit Ethernet ports.

Channelization

Although he QFX10002-60C autosenses the speed of a transceiver and sets the speed
to either 40 Gbps or 100 Gbps, for channelization you must manually configure the port
speed. Any of the 60 physical ports that are configured for 40 Gbps speeds can be
channelized to 4 independent 10-Gigabit Ethernet interfaces using copper or fiber breakout
cables. You can channelize an individual port or a create a port range.

The switch as a whole does not have port groups; instead, port behavior is tied to the
ASIC associated with the port. You must configure each port individually, in order to
channelize a 40-Gigabit Ethernet port to 4 independent 10-Gigabit Ethernet ports. The
first time a port for an associated ASIC is changed from the default configuration mode
(mode D) to the channelization mode (mode A), the FPC reboots. Subsequent
channelization of the ports for that ASIC does not cause the FPC to reboot. However if
one of the channelized ports is changed back to the default, the FPC will again reboot.
See Table 12 on page 34 for the list of available ports and the associated ASIC.
CAUTION: Changing the channelization mode (mode D to mode A or mode
A to mode D) causes the FPC to reboot. Because there can be a slight loss
of data while the FPC reboots, we recommend that you only configure the
changes during a maintenance window.
