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.

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

For more information about the load command, see CLI Explorer.

Cooling System | 24

Juniper Networks EX4650 Ethernet Switches provide connectivity for high-density environments, scalability

for growing networks, and redundancy. The EX4650 provides the flexibility to support mixed 1-Gigabit

Ethernet, 10-Gigabit Ethernet, 25-Gigabit Ethernet, 40-Gigabit Ethernet, and 100-Gigabit Ethernet

environments.

The EX4650 switch is available as a fixed-configuration switch with the following built-in ports:

•

Forty-eight 25-Gigabit Ethernet ports that can operate at 1-Gbps, 10-Gbps, or 25-Gbps speed and

support SFP, SFP+, or SFP28 transceivers.

•

Eight 100-Gigabit Ethernet ports that can operate at 40-Gbps or 100-Gbps speed and support QSFP+

or QSFP28 transceivers. When these ports operate at 40-Gbps speed, you can configure four 10-Gbps

interfaces and connect breakout cables, increasing the total number of supported 10-Gbps ports to 80.

19

When these ports operate at 100-Gbps speed, you can configure four 25-Gbps interfaces and connect

breakout cables, increasing the total number of supported 25-Gbps ports to 80.

Four models are available: two featuring AC power supplies and front-to-back or back-to-front airflow

and two featuring DC power supplies and front-to-back or back-to-front airflow.

Benefits of the EX4650 Switch

EVPN-VXLAN campus architecture—The EX4650 switch extends EVPN-VXLAN beyond the data center,

thus providing customers the building blocks for an enterprise-wide fabric. The EVPN-VXLAN protocol is

suitable for campus architectures because it provides Layer 3 transport with Layer 2 capabilities that allow

enterprises to evolve, while also taking into consideration legacy applications. EX4650 also offers core

aggregation capabilities aimed at enterprises with campus networks that want a compact and highly scalable

solution.

Industry-leading 25-Gbps and 100-Gbps wire speeds: The EX4650 Switch offers industry-leading high

density 25-Gbps and 100-Gbps wire speeds that support 48 ports at 100-Gbps or 48 ports at 25-Gbps,

and 8 100-Gbps uplink ports.

Common data center protocols: Like the EX9000 series, the EX4650 also uses data center network

protocols. The network protocols used in the EX4650 are the Ethernet VPN (EVPN) and the Virtual

Extensible LAN (VXLAN). Engineers typically use it with the Border Gateway Protocol and the VXLAN

encapsulation protocol which creates an overlay network on an existing Layer 3 infrastructure. As a result,

the same engineering team can manage the data center and the campus.

Software

Juniper Networks EX Series Ethernet Switches run Junos OS™, which provides Layer 2 and Layer 3

switching, routing, and security services. The same Junos OS code base that runs on EX Series switches

also runs on all Juniper Networks M Series, MX Series, and T Series routers, and SRX Series Services

Gateways.

EX4650 Switch First View

The EX4650 switch has a 1 U form factor and is shipped with redundant fans (4+1) and redundant power

supplies (1+1).

The EX4650 switch is a 25-Gigabit Ethernet enhanced small form-factor (SFP28) switch with 48 SFP28

ports and 8 100-Gbps quad small form-factor (QSFP28) pluggable ports. Each SFP28 port can operate as

a native 25-Gigabit Ethernet port, 10-Gigabit Ethernet port, and can act as a 1-Gbps port based on the

transceivers inserted. Each of the eight uplink ports can operate as either 100-G or 40-G based on the

optics used. They can also be used as 25-Gbps ports or 10-Gbps ports using breakout cables or

channelization.

20

NOTE:

•

The SFP-T transceivers are supported only on top or bottom ports, upto a maximum of 24 ports

•

The SFP28 speed can be applied only for individual quads (four ports). The speed cannot be

configured for a single port.
