Virtual Chassis technology simplifies network management for

smaller deployments. Up to four interconnected EX2300 switches

can be managed as a single device utilizing a single Junos OS image

and a single configuration file, reducing the overall number of units

to monitor and manage. When the Junos OS is upgraded on the

primary switch in an EX2300 Virtual Chassis configuration, the

software is automatically upgraded on all other member switches at

the same time.

The EX2300 includes port profiles that allow network

administrators to automatically configure ports with security, QoS,

and other parameters based on the type of device connected to the

port. Six preconfigured profiles are available, including default,

desktop, desktop plus IP phone, WLAN access point, routed uplink,

and Layer 2 uplink. Users can select from the existing profiles or

create their own and apply them through the command-line

interface (CLI), J-Web Software interface, or management system.

In addition, a feature called system snapshot makes a copy of all

software files used to run the switch—including the Junos operating

system, the active configuration, and the rescue configuration.

These files can be used to reboot the switch at the next power-up

or as a backup boot option. The Junos OS software can also be

preinstalled on a flash drive and used to boot the EX2300 at any

time.

Another feature, called automatic software download, enables

network administrators to easily upgrade the EX2300 using the

DHCP message exchange process to download and install software

packages. Users simply configure the automatic software download

feature on EX2300 switches acting as DHCP clients and establish a

path to the server where the software package file is installed. The

server then communicates the path to the software package file

through DHCP server messages.

The ZTP feature allows a DHCP server to push configuration details

and software images to multiple switches at boot-up time.

Campus Fabric Deployments

Juniper campus fabrics support these validated architectures with

the EX2300 switch playing the role of access switch in a Virtual

Chassis:

• EVPN multihoming (collapsed core or distribution): A

collapsed core architecture combines the core and distribution

layers into a single switch, turning the traditional three-tier

hierarchal network into a two-tier network. This eliminates the

need for STP across the campus network by providing

multihoming capabilities from the access to the core layer.

EVPN multihoming can be deployed and managed using the

Juniper Mist cloud.

• Core-Distribution: A pair of interconnected EX Series core or

distribution switches provide L2 EVPN and L3 VXLAN gateway

support. The EVPN-VXLAN network between the distribution

and core layers offers two modes: centrally or edge routed

bridging overlay.

In all these EVPN-VXLAN deployment modes, EX2300 switches

can be used in Virtual Chassis configurations.
