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.

ix

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

x

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]

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

Port Panel and Management Panel | 19

FRU Panel | 20

The Juniper Networks PTX1000 Packet Transport Router is a fixed-configuration router that supports

10-Gbps, 40-Gbps, and 100-Gbps port speeds in a compact 2U form factor, enabling service providers to

organically distribute peering points throughout the network.

The system architecture cleanly separates control operations from packet forwarding operations. This

design eliminates processing and traffic bottlenecks, permitting the PTX1000 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 PTX1000 router’s

internal 2 x 64-gigabyte (GB) M.2 SATA solid-state drives (SSDs). The 64-GB SSDs have 50 GB of usable

space—the remaining space is reserved. The Routing Engine is enhanced by a 2.5-GHz quad core Intel

CPU and 32 GB of SDRAM.

17

NOTE: The 2 x 64-GB SSDs installed in the PTX1000 support the request vmhost snapshot

command, which creates a recovery snapshot of the currently running and active file system

partitions, and request vmhost snapshot recovery command, which recovers the primary disk

from the snapshot content stored in the backup disk. In addition, the 64-GB SSDs support

enhanced hardware resiliency through storage partitioning and redundancy.

Earlier versions of the PTX1000 have 2 x 32-GB M.2 SATA SSDs. PTX1000 routers with 32-GB

SSDs do not support the request vmhost snapshot and request vmhost snapshot recovery

commands, and do not support enhanced hardware resiliency. To determine the size of the

SSDs installed in your device, issue the show vmhost hardware CLI command. The capacity

of Disk1 and Disk2 is displayed in the output as 32.0 GB if 32-GB SSDs are installed, and the

capacity is displayed as 50.0 GB if 64-GB SSDs are installed. See the Software Installation and

Upgrade Guide for more information.

•

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

by Juniper Networks. The custom ExpressPlus ASICs enable the PTX1000 to provide up to 2.88 terabits

per second (Tbps) of forwarding capacity. The ExpressPlus 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.

TIP: For information about features supported on PTX Series routers, see Feature Explorer.

Benefits of the PTX1000 Router

•

Increased scalability—The PTX1000 scales to 3 Tbps in a single chassis, supporting up to 288 10-Gigabit

Ethernet interfaces, 72 40-Gigabit Ethernet interfaces, and 24 100-Gigabit Ethernet interfaces, giving

service providers the performance and scalability needed as networks grow. The purpose-built ASICs

in the PTX1000 provide enhanced packet processing for both full IP functionality and MPLS transport,

accommodating scale as traffic continues to increase and optimizing IP/MPLS transit functionality.

•

Space efficiency—Providing high capacity in a compact 2U form-factor, the PTX1000 meets installation

needs for peering Internet exchange points, peering collocations, central offices, and regional networks,

especially in emerging markets.

•

Always-on infrastructure base—The PTX1000 is engineered with full hardware redundancy for cooling,

power supplies, and forwarding, allowing service providers to meet stringent service-level agreements

across the core.

18

Port Panel and Management Panel

The port panel of the PTX1000 contains 72 network ports and port LEDs. The management panel of the

PTX1000 contains console and management ports, a reset button, system status LEDs, clocking ports, and

a USB port. Figure 1 on page 19 shows the PTX1000 port panel and management panel.

Figure 1: PTX1000 Port Panel and Management Panel

2—1— Management panelPort panel

Each of the 72 network ports on the port panel supports quad small form-factor pluggable plus (QSFP+)

transceivers, and is configured as a channelized 4 x 10-Gigabit Ethernet interface by default (for a maximum

of 288 10-Gigabit Ethernet ports). You can configure each of the 72 ports as a 40-Gigabit Ethernet interface.

You can also configure 24 of the 72 network ports as 100-Gigabit Ethernet interfaces. Table 3 on page 19

describes the maximum number of ports for each interface type supported by the PTX1000.

Table 3: Maximum Supported Ports at Each Interface Speed

Maximum Supported PortsInterface Type

28810-Gigabit Ethernet

7240-Gigabit Ethernet

24100-Gigabit Ethernet

NOTE: You can purchase a licensed model of the PTX1000 that allows you to use 18 of the 72

network ports. You can use 18 ports in any combination, for a maximum of 72 10-Gigabit Ethernet

interfaces, 18 40-Gigabit Ethernet interfaces, or 6 100-Gigabit Ethernet interfaces. You can

purchase additional licenses to enable the remaining network ports. Each license enables an

additional 18 of the 72 total network ports.

19

You manage the PTX1000 by using the Junos OS CLI, which is accessible through the console and

out-of-band management ports on the management panel. In addition, the management panel has system

status LEDs that alert you to minor or major alarms or other issues with the router, external clock

synchronization ports, and a USB port to support software installation and recovery.

For more information about the port and management panels, see “PTX1000 Port Panel” on page 23 and

“PTX1000 Management Panel” on page 32.

FRU Panel

The field-replaceable unit (FRU) panel of the PTX1000 contains the fan modules and power supplies for

the PTX1000. Figure 2 on page 20 shows the PTX1000 FRU panel.

Figure 2: PTX1000 FRU Panel

3—1— ESD pointPower supplies (4)

2—Fan modules (3)

The cooling system in a PTX1000 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 module has dual

counter-rotating fans. These fan modules can be hot-swapped—you do not need to power off the router

or disrupt routing function to replace a fan module.

In the PTX1000 cooling system, cool air enters through the vents in the port panel and hot air exhausts

through the FRU panel. This type of airflow is known as airflow out or port-to-FRU airflow.

The PTX1000 has four 1600-W power supplies, either AC or DC depending on your configuration. Each

power supply provides 12-VDC output with a standby voltage of 12 VDC. The power supplies can be

hot-swapped—you do not need to power off the router or disrupt routing function to replace a power

supply

For more information about the components on the FRU panel, see “PTX1000 Cooling System Description”

on page 36, “PTX1000 AC Power Supply Description” on page 40, and “PTX1000 DC Power Supply

Description” on page 41.
