Ethernet ports. Use the set chassis fpc
slot-number port port-number channel-speed speed
command to
change the port speed.
Each QSFP+ port (61, 62, 63, and 65 is part of a port group and is controlled either by the associated
QSFP28 port (60 or 64). A QSFP28 port operating at 40-Gpbs speeds, the QSFP+ ports can be
configured to support:
• 40-Gigabit Ethernet using QSFP+ optical transceivers. The default speed is 40 Gbps.
• 10-Gigabit Ethernet using breakout cables with attached optical transceivers. When configured for
channelization, the system converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit
Ethernet ports. Use the
set chassis fpc
slot-number port port-number channel-speed speed
command to
change the port speed.
Each SFP+ port (0 through 59) can be configured to support:
• 10-Gigabit Ethernet using SFP+ optical transceivers. The default speed is 10 Gbps.
• 1-Gigabit Ethernet using SFP optical or SFP-T copper transceivers. See
Using Copper and Fiber SFP
Transceivers .
Any of the 66 ports 0 through 65 can be configured as either uplink or access ports. The ports are
enabled by default, and the default configuration adds the ports to the default VLAN.
Port Groups
The six combination ports of QSFP28 and QSFP+ can operate either as six independent 40-Gigabit
Ethernet ports or as two port groups. The first port group is controlled by QSFP28 port 60 and
administratively bundled with QSFP+ ports 61 and 62. The second port group is controlled by QSFP28
port 64 and administratively bundled with QSFP+ ports 63 and 65. To enable the port group, insert a
100-Gigabit Ethernet transceiver into the QSFP28 port and configure a port for 100-Gbps. Junos OS
enables the QSFP28 port at 100-Gbps speed and disables the two QSFP+ ports bundled in the port
