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;

}

} }

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]

xii

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.

System Architecture

The system architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the QFX10002 to achieve high performance.

Control operations are performed by the Routing Engine, which runs the Juniper Networks Junos

•

operating system (Junos OS). The Routing Engine handles routing protocols, traffic engineering, policy, policing, monitoring, and configuration management. Junos OS is installed on the QFX10002 internal solid-state drives (SSDs). QFX10002-36Q and QFX10002-72Q have 2 x 32-GB SSD and the QFX10002-60C has 2 x 64-GB SSDs. The Routing Engine has a 2.5-GHz quad core Intel CPU and has 16 GB of SDRAM on the QFX10002-36Q and QFX10002-72Q. There is 32 GB of SDRAM on the QX10002-60C.

Forwarding operations are performed by the Packet Forwarding Engines, which include custom ASICs

•

designed by Juniper Networks. The Q5 ASICs enable the QFX10002 to provide up to 2.88 terabits per second (Tbps) of throughput on the QFX10002-36Q, 5.76 Tbps on the QFX10002-72Q and 12 Tbps on the QFX10002-60C. The Q5 ASICs are connected to Hybrid Memory Cubes (HMCs). These high-efficiency memory modules provide packet buffering, virtual output queue (VOQ) memory, and improved logical system scale.

The cooling system in a QFX10002 consists of three 80-W fan modules that operate at 150 cubic feet per minute (CFM) at full speed as well as fans housed in the power supplies. Each fan modules has dual counter-rotating fans. These fan modules can be hot-swapped and hot-inserted, meaning that– you do not need to power off the switch or disrupt the switching function to replace a module.

in the QFX10002 cooling system, cool air enters through the vents in the port panel and hot air exhausts through the field-replaceable unit (FRU) panel. This type of airflow is known as airflow out or port-to-FRU airflow.

The four AC or DC 1600-W power supplies are installed by the factory in the QFX10002-72Q and QFX10002-60C; two power supplies are installed in the QFX10002-36Q. See Figure 4 on page 22 for an example of the QFX10002-72Q FRU panel. Each power supply provides 12 VDC output with a standby voltage of 12-VDC.The AC or DC power supplies in a QFX10002 are hot-removable and hot-insertable FRUs.

The power supply bays on the QFX10002-72Q and QFX10002-36Q are numbered horizontally from the top left to the bottom right. The QFX10002-60C power supply bays are numbered vertically from the top left to the bottom right, which matches CLI output.

System Software

QFX Series devices use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS is installed on a QFX10002 switch’s 25-gigabyte (GB) internal NAND solid state flash drive. The same Junos OS code base that runs on QFX10002 switches also runs on all Juniper Networks EX Series switches, and M Series, MX Series, and T Series routers.

For more information about which features are supported on QFX Series devices, see Feature Tracker.

You manage the switch using the Junos OS command-line interface (CLI), which is accessible through the console and out-of-band management ports on the device.

QFX10002 Component Redundancy

The following hardware components provide redundancy on QFX10002 models:

Power supplies

•

As shown in Table 6 on page 24, the QFX10002-72Q and QFX10002-60C can operate with a single DC input power supply or a single AC input power supply for 220VAC operation. A minimum of two AC power supplies are required to operate the QFX10002-72Q and QFX10002-60C at 110VAC. The QFX1002-36Q can operate with a single DC input power supply or it can operate with a single AC power supply at 110VAC and 220VAC.

CAUTION: When running the switch in non-redundant mode, install a power supply

cover (QFX10002-PWR-BLNK) in any unused power bays for safety, cooling, and emissions control.

The recommended configuration is to run the switch with twice as much power as needed, also called 2N, for full power redundancy. To provide additional power for switch redundancy or feed-redundancy, see Table 6 on page 24.

Cooling system—All models of the QFX10002 have three fan modules. Each fan module is a redundant

•

unit containing two fans. If a fan module fails and is unable to keep the QFX10002 within the desired temperature thresholds, chassis alarms occur and the QFX10002 device might shut down.

QFX10002 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The QFX10002 FRUs are hot-removable and hot-insertable: you can remove and replace them without powering off the switch or disrupting the switching function.

CAUTION: Replace a failed fan module with a new fan module within one minute of

removal to prevent chassis overheating.

Table 7 on page 26 lists the FRUs for the QFX10002-72Q and actions to take before removing them.

The port panel of the QFX10002-36Q consists of 36 quad small-form factor pluggable plus (QSFP+) ports that support 10-Gbps, 40-Gbps and 100-Gbps port speeds. Of these 36 ports, 12 ports accept QSFP28 transceivers, which are dual speed 40- or 100-Gigabit Ethernet optical transceivers.

This topic describes:

Overview

Any of the 36 ports 0 through 35 can be configured as either uplink or network ports. See

Figure 6 on page 28.

The second and sixth port in each 6XQSFP+ socket can be configured to support:

100-Gigabit Ethernet using 28-Gbps QSFP28 optical transceivers and 100-Gbps active optical cables

•

(AOCs). When a QSFP28 transceiver is inserted into the ports marked with a fine black line underneath the socket and the port is configured for 100-Gigabit Ethernet, the two adjacent ports are disabled and the QSFP28 is enabled for 100-Gigabit Ethernet.

40-Gigabit Ethernet using QSFP+ optical transceivers or 40-Gbps direct attach copper (DAC) cables.

•

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. The two adjacent QSFP+ ports in the port group are also configured for channelization at the same time. You cannot configure a single port for channelization.

Every second and sixth port in a 6XQSFP cage on a QFX10002 supports 100-Gigabit Ethernet using QSFP28 transceivers. These 100-Gigabit Ethernet ports work either as 100-Gigabit Ethernet or as 40-Gigabit Ethernet, but are recognized as 40-Gigabit Ethernet by default. See Figure 7 on page 30 for a close up view of a 6XQSFP+ cage. The 100-Gigabit Ethernet are designated by a fine black line underneath the port. See Figure 8 on page 30. When a 40-Gigabit Ethernet transceiver is inserted into a 100-Gigabit Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. However, when an 100-Gigabit Ethernet transceiver is inserted into the port, the transceiver is not automatically recognized and is not seen in the output of the show chassis hardware command. To enable 100-Gigabit Ethernet on the marked ports, use the set chassis fpc command. For example, to enable port 11 for 100 Gbps speeds:

[edit] user@switch#

set chassis fpc 0 pic 0 port 11 speed 100g

The port then recognizes the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet ports. See Figure 9 on page 31.

Figure 7 on page 30 shows one of the six 6XQSFP+ cages on a QFX10002-36Q.
