Unlike the QFX10000-36C line card, the QFX10000-30C line card 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
ports and the associated ASIC and
disabled ports.
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.
Available Ports
0, 2, 4, 8
10, 12, 14, 18
20, 22, 24, 28
1, 3, 5, 9
11, 13, 15, 19

To change from the default mode to 40-Gigabit Ethernet channelized mode, use the
Junos OS operational command set chassis fpc slot-number pic 0 port port number
channelization-speed 10g.
Switch Ports
Each of the 30 QSFP28 ports supports:
100-Gigabit Ethernet using QSFP28 optical transceivers. When a QSFP28 transceiver
is inserted into any of the ports, the QSFP28 port is enabled for 100-Gigabit Ethernet.
40-Gigabit Ethernet using QSFP+ optical transceivers. When a QSFP+ transceiver is
inserted into any of the ports, the QSFP+ port is enabled for 40-Gigabit Ethernet.
100-Gigabit Ethernet active optic cables (AOC)
QSFP28 direct attach copper (DAC) cables
