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;

}

} }

xii

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]

xiii

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.

The QFX5100 line of 10/40GbE switches delivers low latency, flexible deployment options, and rich automation features. QFX5100 Switches build a strong underlay foundation for flexible, high-performance, standards-based fabrics and routing that improve network reliability and agility.

QFX5100 Hardware

QFX5100 line of switches offer two compact 1 U models and a 2 U model that provide wire-speed packet performance, very low latency, and rich set of Layer 2 and Layer 3 features. In addition to a high-throughput Packet Forwarding Engine, the performance of the control plane running on all the QFX5100 switches is enhanced by the 1.5 Ghz dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.

The QFX5100-24Q-AA switch has a 2.5 GHz 4-core Intel CPU with 32 GB of memory and 128 GB of SSD storage.

The QFX5100 line of switches include both 10GE and 40GE fixed-configurations:

QFX5100-48S

•

As shown in Figure 1 on page 20, the QFX5100-48S is a 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) top-of-rack switch with 48 SFP+ ports and 6 Quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10 Gigabit port, when 10 Gbps optics are used. The SFP+ ports can also run at 1 Gbps, or at 100 Mbps speeds when 1_Gigabit optics are inserted. Each QSFP+ port (48 through

53) can operate as uplink ports or four QSFP+ port (50 through 53) can operate at native 40-Gigabit speed or as 4 independent 10-Gigabit port speeds. The 6 QSFP+ ports can be used as either access ports or as uplinks. The QFX5100-48S provides full duplex throughput of 1.44 Tbps. The QFX5100-48S has a 1 U form factor and comes standard with redundant fans and redundant power supplies. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.

•

As shown in Figure 4 on page 23, the QFX5100-48TH is the same form factor and port configuration as the QFX5100-48T. The QFX5100-48TH is specifically designed for Junos Fusion and comes pre-configured with Satellite Network Operational System (SNOS) instead of Juniper Networks Junos OS. The switch may not be converted to Junos OS without an additional license. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC power supplies.

The QFX5100-48TH can only be used as a satellite device in a Junos Fusion system.

QFX5100-24Q

•

As shown in Figure 5 on page 23, the QFX5100-24Q is a 40-Gigabit Ethernet QSFP+ switch with 24 high-density QSFP+ ports. Each QSFP+ port can operate as a native 40 Gbps port or as 4 independent 10 Gbps ports. The QFX5100-24Q switch has a 1 U form factor and comes standard with redundant fans and redundant power supplies. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.

The QFX5100-24Q switch has two module bays for the optional expansion module, QFX-EM-4Q, which can add a total of 8 additional QSFP+ ports to the chassis. When operating as a standalone switch and fully populated with QFX-EM-4Q Expansion Modules, the QFX5100-24Q switch is equivalent to 80 10 Gbps interfaces and 4 40-Gbps interfaces. Of these total ports, 104 logical ports are available for 10G port channelization. For full details on the different port channelization modes, see “Port Panel of

a QFX5100-24Q Device” on page 34. All ports on the QFX5100-24Q and QFX-EM-4Q can be configured

as either access ports or as uplinks. The QFX5100-24Q switch provides full duplex throughput of 2.56 Tbps.

EX4600-EM-8F, which provides eight additional 10-Gigabit Ethernet Enhanced Small Form-Factor

•

Pluggable (SFP+) or four 1-Gigabit Ethernet ports. See Figure 7 on page 25.

CAUTION: Use only the top four ports or the bottom four ports for SFP

transceivers. Because SFP transceivers are larger than SFP+ transceivers, attempting to stack SFP transceivers can cause internal damage to the module.

Figure 7: EX4600-EM-8F Expansion Module

NOTE: The EX4600-EM-8F is not supported on the QFX5100-24Q running in QFabric

systems.

The QFX5100-24Q is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and it is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic.

QFX5100-24Q-AA

•

As shown in Figure 8 on page 26, the QFX5100-24Q-AA is a 1 U, top-of-rack, 40-Gigabit Ethernet QSFP+ switch with 24 high-density QSFP+ ports. Each QSFP+ port can be configured to support 40-Gigabit Ethernet or as a set of 4 independent 10-Gigabit Ethernet ports. The QFX5100-24Q-AA can also be configured to support twenty-four 40-Gigabit Ethernet interfaces or ninety-six 10-Gigabit Ethernet interfaces using breakout cables (channelization mode) with 1280 Gbps output. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies. The QFX5100-24Q switch provides full duplex throughput of 2.56 Tbps.

The QFX5100-24Q-AA module bay can accommodate a single Packet Flow Accelerator (PFA) double-wide expansion module (QFX-PFA-4Q) or two single-wide optional expansion modules (two or one each of QFX-EM-4Q and EX4600-EM-8F). The QFX-PFA-4Q, which features a high-performance field-programmable gate array (FPGA), provides four additional QSFP+ ports to the chassis. Each QFX-EM-4Q adds four QSFP+ ports to the chassis and each EX4600-EM-8F adds eight 10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can also be configured as either access ports or uplink ports, but only ports 0 and 2 can be channelized using port mode. For full details on the different port channelization modes, see “Port Panel of a QFX5100-24Q Device” on page 34. All ports on the QFX5100-24Q and QFX-EM-4Q can be configured as either access ports or uplink ports.

This switch provides the hardware support to enable PTP boundary clocks by using the QFX-PFA-4Q module. The QFX5100-24Q-AA also supports GPS in and out signals when QFX-PFA-4Q is installed.

The CPU subsystem of this switch includes a 2-port 10-Gigabit Ethernet network interface card (NIC) to provide a high bandwidth path or to alternate traffic path to guest VMs directly from the Packet Forwarding Engine.

Figure 8: QFX5100-24Q-AA Port Panel with QFX-PFA-4Q

The QFX5100-24Q-AA can be used as a standalone switch that supports high frequency statistics collection. Working with Juniper Networks Cloud Analytics Engine, this switch monitors and reports the workload and application behavior across the physical and virtual infrastructure.

The QFX5100-24Q-AA supports the following expansion modules to increase port density:

QFX-PFA-4Q (double-wide), which provides four additional QSFP+ ports. See Figure 9 on page 26.

•

•

Figure 6 on page 24.

EX4600-EM-8F (single-wide), which provides 8 additional 10-Gigabit Ethernet SFP+ ports. See

•

Figure 7 on page 25.

The QFX5100-24Q switch supports the QFX-PFA-4Q and you must take the switch offline before replacing the expansion module. Any combination of EX4600-EM-8F and QFX-EM-4Q is also supported. These two expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of a QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic.

QFX5100-96S

•

As shown in Figure 10 on page 27, the QFX5100-96S switch is a is a 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) top-of-rack switch with 96 SFP+ ports and 8 Quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10 Gigabit port, when 10 Gbps optics are used. The SFP+ ports can also run at 1 Gbps, or at 100 Mbps speeds when 1_Gigabit optics are inserted. QSFP+ ports 96 and 100 can operate at native 40 Gbps speed or can be channelized to 4 independent 10 Gbps port speeds. The 8 QSFP+ ports can be used as either access ports or as uplinks. The QFX5100-96S switch

has a 2 U form factor and comes standard with redundant fans and redundant power supplies. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.

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 QFX5100 switch’s 32-gigabyte (GB) internal solid state flash drive. The same Junos OS code base that runs on QFX5100 switches also runs on all Juniper Networks EX Series switches, M Series, MX Series, and T Series routers.

Participation in a QFX5110 Virtual Chassis or a QFX5110 VCF requires the same Junos OS image on all devices in the Virtual Chassis or VCF. Junos OS 17.3R1 or later is the minimum software release for QFX5110 Virtual Chassis or QFX5110 VCF.

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

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

QFX5100 Device Models

The QFX5100 switches have 24, 48, or 96 port configurations. The 24 port switches can be expanded to a maximum of 32 QSFP+ ports using expansion modules. All switches are available with either AC or DC power supply and with either airflow-in or airflow-out cooling. In legacy switches, or switches with an LCD, this air flow is called front-to-back and back-to-front.
