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.

The QFX5110 line of switches delivers low latency, flexible deployment options, and rich automation features. QFX5110 Switches build a strong underlay foundation for flexible, high-performance, standards-based fabrics and routing that improve network reliability and agility.

This topic covers:

Benefits of QFX5110

Flexible fabric support—QFX5110 offers multiple fabric options to fit your desired network architecture:

Virtual Chassis (VC), with up to 10 members

•

Virtual Chassis Fabric (VC), which offers a single pane management for up to 20 nodes

•

MC-LAG, which provides dual-homing with reduced complexity related to STP

•

Junos Fusion Datacenter, where QFX5110 can operate as a satellite leaf node for 1 Gigabit, 10

•

Gigabit, 40 Gigabit, or 100 Gigabit connectivity

Overlay options—QFX5110 provides L2 and L3 VXLAN gateway support that works in conjunction with

a robust EVPN control plane to efficiently manage your virtualized workloads. Another option, OVSDB-VXLAN can be introduced to stitch virtualized and physical workloads.

High density and low latency applications—Powered with high density 10 Gigabit or 40 Gigabit network

ports and four 100G uplinks, the QFX5110 delivers 1.76 Tbps of throughput and a low latency of 550 nS. Your legacy applications continue to be supported by 100 Mbps or 1 Gigabit copper SFP transceivers.

QFX5110 Models Overview

The QFX5110 line of switches offers two compact 1 U models that are ideal for top-of-rack, QFX Virtual Chassis, or Virtual Chassis Fabric (VCF) deployments, the 48-port QFX5110-48S and the 32-port QFX5110-32Q. Performance of the control plane running on all the QFX5110 switches is enhanced by the 1.8-Ghz quad-core Intel CPU with 16 GB of memory and 64 GB of solid-state drive (SSD) storage. Both models offer flexible port configurations of 1-Gigabit Ethernet, 10-Gigabit Ethernet, 40-Gigabit Ethernet, and 100-Gigabit Ethernet.

Both models can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies.

The QFX5110-32Q can be used as:

A standalone switch (Junos OS Release 17.2R1 and later).

•

A primary, backup, or line card in a QFX5110 Virtual Chassis (Junos OS Release 17.3R1 and later).

•

A QFX5110 Series Virtual Chassis allows you to connect up to 10 QFX5110 or supported QFX5100 switches into one logical device and manage the device as a single chassis using a ring topology. The following QFX5100 switches are supported in a QFX5110 Virtual Chassis:

QFX5100-24Q

•

QFX5100-48S

•

QFX5100-96S

•

For a QFX5100 switch to participate in a QFX5110 Virtual Chassis, the switch must have the same software version and image installed as the software running on the QFX5110 switches in the Virtual Chassis. You do not need to configure mixed mode. In a QFX5110 Virtual Chassis, we recommend to use QFX5110 switches in the primary and backup Routing Engine roles, and QFX5100 switches only in the linecard role.

A spine or leaf device in a QFX5110 VCF (Junos OS Release 17.3R1 and later).

•

VCF uses QFX Virtual Chassis technology to interconnect multiple devices into a single logical device and manage that device as a single logical device inside of a fabric architecture. You can configure up to a total of 20 QFX5110 or QFX5100 devices in a VCF. Out of the 20 total devices, you can configure a maximum of 4 spine devices. You can use these models in any combination as leaf devices:

QFX5100-24Q

•

QFX5100-48S

•

QFX5100-48T (Junos OS Release 17.3R2 and later)

•

QFX5110-48S Hardware

As shown in Figure 1 on page 21, the QFX5110-48S is a 10-Gigabit Ethernet enhanced small form-factor pluggable plus (SFP+) switch with 48 SFP+ ports and four 100-Gbps quad small form-factor (QSFP) pluggable solution (QSFP28) ports. Each SFP+ port (0 through 47)can operate as a native 10-Gigabit Ethernet port or a 1-Gigabit Ethernet port when 1-Gigabit Ethernet optics are inserted.

Each QSFP28 port (48 through 51) can operate as a native 100-Gigabit Ethernet port, a native 40-Gigabit Ethernet port, or as 4 independent 10-Gigabit ports when using breakout cables. The four QSFP28 ports can be used as either access ports or as uplinks. The QFX5110-48S provides an aggregate throughput of 960 Gbps. The QFX5110-48S has a 1 U form factor and comes standard with redundant fans and redundant power supplies.

g050492

As shown in Figure 2 on page 22, the QFX5110-32Q is a flexible configuration switch allowing either 32 ports of 40-Gigabit Ethernet quad small form-factor pluggable plus (QSFP+) or 20 ports of QSFP+ and 4 ports of high-density 100-Gigabit Ethernet quad small form-factor pluggable solution (QSFP28). Each QSFP+ port can operate as a native 40-Gigabit Ethernet port, or as four independent 10-Gigabit Ethernet ports when using breakout cables. The four QSFP28 ports are available either as access ports or as uplinks.

The QFX5110-32Q can be channelized using one of the available system modes. For full details on the different port channelization modes, see “QFX5110-32Q Port Panel” on page 29. The QFX5110-32Q switch provides an aggregate throughput of 2.56 Tbps.

Figure 2: QFX5110-32Q Port Panel

System Software

QFX Series devices use the Junos operating system (OS), which is installed on a QFX5110 switch’s 64-GB internal solid-state flash drive. The same Junos OS code base that runs on QFX5110 switches also runs on all Juniper Networks EX Series switches, and M Series, MX Series, and T Series routers.

The QFX5110-48S switch is supported on Junos OS Release 15.1X53-D210 and later; the QFX5110-32Q is supported on Junos OS 17.2R1 and later.

Software features are categorized into three tiers: base, premium, and advanced:

Junos OS base features such as Layer 2 and Layer 3 switching, multicast, automation, programmability,

•

Zero Touch Provisioning (ZTP), and basic monitoring are enabled by default from the factory.

Junos OS premium features such as Border Gateway Protocol (BGP), Intermediate System-to-Intermediate

•

System (IS-IS), and Virtual Extensible Local Area Network (VXLAN) require a QFX5K-C1-PFL license on each QFX5110 switch to use these features.

Junos OS advanced features include Multiprotocol Label Switching (MPLS) in addition to all of the

•

premium features. A QFX5K-C1-AFL license is required on each QFX5110 switch to use these features.

When using QFX5110 switches in a QFX5110 VCF, PFL and AFL licenses are required on the spine device: leaf devices do not require licensing.

QFX5110 switches employ the security feature, Secure Boot, which is based on the UEFI 2.4 standard. The BIOS has been hardened and serves as a core root of trust. The BIOS updates, the bootloader, and the kernel are cryptographically protected. No action is required to implement Secure Boot.

If a premium or advanced feature is configured on the QFX5110 without a valid license, an alarm is raised and system log (syslog) messages are generated.

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.

QFX5110 Hardware Models

The QFX5110 switches have 32 or 48 port configurations. Both switches are available with either AC or DC power supply and with either airflow-in or airflow-out cooling. All models of the QFX5110, except the QFX5110-32Q_CHAS, ship with two power supplies and five fans installed by default.

Understanding Hardware Redundancy of QFX5110 Components and Functionality

The following hardware components provide redundancy on a QFX5110:

Power supplies—The QFX5110 can operate with one power supply. However, all QFX5110 switches,

•

except the QFX5110-32Q-CHAS, ship with two power supplies preinstalled for redundancy.. Each power supply provides power to all components in the switch. If two power supplies are installed, the two

power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply takes over the electrical load without interruption.

To provide power redundancy to the system, both power supplies must be installed. Connect power source feed A to one power supply and power source feed B to the second power supply.

CAUTION: Do not connect feed A and feed B to the same power supply input

terminal.

Cooling system—All QFX5110 switches, except the QFX5110-32Q-CHAS, ship with five fan modules

•

installed. If a fan module fails and is unable to keep the QFX5110 within the desired temperature thresholds, chassis alarms occur and the QFX5110 can shut down.

QFX5110 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5110 FRUs are hot-insertable and hot-removable: you can remove and replace one of them without powering off the switch or disrupting the switching function.

CAUTION: Replace a failed power supply with a blank panel or new power supply

within one minute of removal to prevent chassis overheating. The switch continues to operate with only one power supply running. Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating. Do not operate the switch with missing FRUs for longer than one minute.

Table 4 on page 25 lists the FRUs for the QFX5110 and actions to take before removing them.

The port panel of the QFX5110-48S is primarily comprised of 48 small form-factor pluggable plus (SFP+) and 4 quad small form-factor pluggable solution (QSFP28) ports. It also provides a central location for the Precision Time Protocol (PTP) connections to a grandmaster clock.

This topic describes:

Switch Overview

The port panel of the QFX5110-48S supports 48 logical 10-GbE ports when operating as a standalone switch. These data ports (0 through 47) support either 1-Gbps or 10-Gbps SFP+ transceivers. You can also use SFP+ DAC cables and 10-Gbps active optical cables (AOC) in any access port. Starting in Junos OS Release 18.3R1, the 10-GbE ports also support 100 Mbps.

The remaining 4 QSFP28 ports (48 through 51) support speeds of 40 GbE or 100 GbE. Each port can be configured as an independent 100-GbE port or as an independent 40-GbE port. These port are usually used as uplinks or Virtual Chassis Ports (VCP) on QFX5110 Virtual Chassis or Virtual Chassis Fabric (VCF). In 40-GbE mode, these ports can be channelized using QSFP+ to SFP+ DAC breakout (DACBO) cables.

The port panel also provides PTP connections to a grandmaster clock (requires Junos OS Release 18.1R1). There are also 10-MHz pulses-per-second (PPS) SubMiniature B (SMB) input and output connections to measure the timing drift to and from the grandmaster clock.

Figure 3 on page 28 shows the port panel of the QFX5110-48S.

CAUTION: Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly

above or below another 1GbE copper transceiver. Use only the top row or bottom row to avoid damage to the device caused by some types of copper transceivers when the transceivers are installed above or below each other. However, if you are using copper transceivers with the OEM part number FCLF8521P2BTL-J1 printed on the transceiver label, you can install the transceivers in any port with no restrictions. For devices that support 10GbE copper transceivers, there is no similar restriction.

Channelizing Interfaces

For downstream traffic, the QFX5110-48S has 4 physical or 16 logical ports that can be used for port channelization. The default 100-Gigabit Ethernet ports can be configured as 40-Gigabit Ethernet, and in this configuration can either operate as dedicated 40-Gigabit Ethernet ports or can be channelized to 4 independent 10-Gigabit Ethernet ports using copper or fiber breakout cables.

To channelize the ports, manually configure the port speed using the set chassis fpc slot-number port port-number channel-speed speed command, where the speed can be set to 10-Gigabit Ethernet, 40-Gigabit Ethernet, or 100-Gigabit Ethernet. The ports do not support auto-channelization.

Virtual Chassis and Virtual Chassis Fabric

To connect QFX5110 switches as members in a QFX5110 Virtual Chassis, you need a pair of dedicated ports on each switch and cables that link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to a upstream and downstream member. QFX5110 switches are recommended in the primary, backup, or line card role. You may only mix QFX5100 members with QFX5110 members in a QFX5110 Virtual Chassis; no other QFX Series or EX Series switches are supported. See “Connecting QFX5110 and QFX5100 Members in a

QFX5110 Virtual Chassis” on page 116 for a a diagram of cabling QFX5110 switches in a ring topology.

To connect a QFX5110 switch as a spine or leaf device in a Virtual Chassis Fabric (VCF), you need a pair of dedicated ports and cables that link each spine device and leaf device in the VCF. All spine devices have at least one direct VCP connection to each leaf device in the VCF. See “Connecting QFX5110 in a QFX5110

Virtual Chassis Fabric” on page 117 for a cabling diagram.

The port panel of the QFX5110-32Q primarily comprises 28 quad small form-factor pluggable plus (QSFP+)

ports and 4 quad small form-factor pluggable solution (QSFP28) ports. The mixture of QSFP+ and QSFP28 ports allows for flexible configuration as either all 40-Gigabit Ethernet ports or a mixture of 40-Gigabit Ethernet and 100-Gigabit Ethernet for high-speed uplinks. The port panel also provides a central location for the Precision Time Protocol (PTP) connections to a grandmaster clock.

This topic describes:

Switch Overview

The ports on the QFX5110-32Q support 40-Gbps or 100-Gbps speeds natively. All ports autosense the type of transceiver and set the port to the corresponding speed. The QSFP+ ports can support channelization to four independent 10 GbE downstream ports, see “Channelizing Interfaces” on page 31. Although all network ports can be configured as either uplink or as access ports, best practice is to configure the four QSFP28 ports (28 through 31) as uplinks to take advantage of the 100-Gbps speeds.
