Documentation and Release Notes
To obtain the most current version of all Juniper Networks®technical documentation, see the product
documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.
If the information in the latest release notes differs from the information in the documentation, follow the
product Release Notes.
Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts.
These books go beyond the technical documentation to explore the nuances of network architecture,
deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
Using the Examples in This Manual
If you want to use the examples in this manual, you can use the load merge or the load merge relative
command. These commands cause the software to merge the incoming configuration into the current
candidate configuration. The example does not become active until you commit the candidate configuration.
If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
is a full example. In this case, use the load merge command.
If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In
this case, use the load merge relative command. These procedures are described in the following sections.
Merging a Full Example
To merge a full example, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following configuration to a file and name the file ex-script.conf. Copy the
ex-script.conf file to the /var/tmp directory on your routing platform.
system {
scripts {
commit {
file ex-script.xsl;
}
}
}
interfaces {
fxp0 {
disable;
unit 0 {
family inet {
address 10.0.0.1/24;
}
}
}
}
xiv
2. Merge the contents of the file into your routing platform configuration by issuing the load merge
configuration mode command:
[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete
Merging a Snippet
To merge a snippet, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the
ex-script-snippet.conf file to the /var/tmp directory on your routing platform.
commit {
file ex-script-snippet.xsl; }
2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode
command:
[edit]
user@host# edit system scripts
[edit system scripts]
xv
3. Merge the contents of the file into your routing platform configuration by issuing the load merge
relative configuration mode command:
[edit system scripts]
user@host# load merge relative /var/tmp/ex-script-snippet.conf
load complete
For more information about the load command, see CLI Explorer.

Routing and Control Board
The routing and control board (RCB) (see Figure 5 on page 28) contains a Routing Engine and is responsible
for the system management and system control in QFX10016. See “QFX10000 Routing and Control Board
Description” on page 92. RCBs are FRUs that are installed in the front of the chassis in the slots labeled
CB0 and CB1. The base configuration has a single RCB; the fully-redundant configuration has two RCBs.
The RCB also contains Precision Time Protocol (PTP) ports and four Media Access Control Security (MACsec)
capable ports. See “QFX10016 Components and Configurations” on page 33. The base configuration has
a single RCB; the fully redundant configuration has two RCBs.

Line Cards
The QFX10016 features 16 horizontal line card slots and supports line rate for each line card. The line
cards combine a Packet Forwarding Engine (PFE) and Ethernet interfaces enclosed in a single assembly.
The QFX10000 line card architecture is based on a number of identical, independent PFE slices, each with
500 Gbps full-duplex throughput. Line cards are FRUs that can be installed in the line card slots labeled 0
through 15 (top to bottom) on the front of the switch chassis. All line cards are hot-removable and
hot-insertable.

Five line cards are available for the QFX10016:
QFX10000-36Q–provides 36 ports of 40-gigabit QSFP+. Twelve ports are designed to be 100-Gigabit
•
capable using QSFP28. Each of the 40-Gigabit QSFP+ can be configured as either a native 40-Gigabit
port or four 10-Gigabit ports using a breakout cable. With breakout cables, the line card supports a
maximum of 144 logical 10-Gigabit Ethernet ports.
QFX10000-30C–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28. The ports autodetect
•
the type of transceiver installed and set the configuration to the appropriate speed. Each of the 40-gigabit
ports can be configured as either a native 40-gigabit port or four 10-gigabit ports using a breakout cable.
With breakout cables, the line card supports a maximum of 96 logical 10-Gigabit Ethernet ports.
QFX10000-30C-M–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28 that support MACsec
•
security features.
QFX10000-60S-6Q–provides 60 SFP+ ports that can be configured for either 1-gigabit or 10-gigabit
•
speeds. The card also provides six flexible configuration ports for 100-gigabit and 40-gigabit speeds. Of
the six flexible configuration ports, two ports have QSFP28 sockets that support either 100-gigabit or
40-gigabit speeds. The remaining four ports have QSFP+ sockets that can be configured as either a
native 40-gigabit port or four 10-gigabit ports using a breakout cable. With breakout cables, the line
card supports a maximum of 84 logical 10-Gigabit Ethernet ports.
QFX10K-12C-DWDM-provides 6 coherent dense wavelength-division multiplexing (DWDM) ports with
•
built-in optics. The card supports MACsec security features and provides a flexible rate modulation at
100 Gbps, 150 Gbps, and 200 Gbps speeds.
See Figure 6 on page 29 for an example of a QFX10000 line card.

Switch Interface Boards
Five switch interface boards (SIBs) provide the necessary switching functionality to a base configuration
QFX10016. A sixth SIB is available in the redundant configuration to provide n+1 redundancy. SIBs are
installed between the line cards and the fan trays inside of the chassis (see Figure 7 on page 29). Each
QFX10016 SIB has 16 connectors that match to a line card slot, eliminating the need for a backplane.
When all six SIBs are installed, the QFX10016 has a net switching capacity of 96 Tbps. See “QFX10016
Switch Interface Board Description” on page 88.

Cooling System
The cooling system in a QFX10016 consists of two hot-removable and hot-insertable FRU fan trays (see
Figure 8 on page 30) and two fan tray controllers (see Figure 9 on page 30). Each fan tray contains 21
fans. The fan trays install vertically on the rear of the chassis and provide front-to-back chassis cooling.
See “QFX10016 Cooling System and Airflow” on page 47.
