Each EX4100 model offers 4 x 1/10GbE small form-factor

pluggable plus transceiver (SFP+) fixed uplink ports. The EX4100

switches include 4 x 10GbE/25GbE SFP28 ports to support Virtual

Chassis connections, which can be reconfigured for use as Ethernet

ports for uplink connectivity. EX4100 switches also include high

availability (HA) features such as redundant, hot-swappable power

supplies and field-replaceable fans to ensure maximum uptime. In

addition, -24 port and -48 port Multi-Gigabit Ethernet EX4100

switch models offer standards-based 802.3af/at/bt (PoE/PoE+/PoE

++) for delivering up to 90 watts on any access port. The EX4100

switches can be configured to deliver fast PoE capability, which

enables the switches to deliver PoE power to connected PoE

devices within a few seconds of power being applied to the

switches.

Architecture and Key Components

Cloud Management with Juniper Mist Wired Assurance Driven by

Mist AI

EX4100 switches can be quickly and easily onboarded (Day 0),

provisioned (Day 1), and managed (Day 2+) from the cloud with

Juniper Mist Wired Assurance, which brings AI-powered

automation and insights that optimize experiences for end users

and connected devices. The EX4100 provides rich

Junos® operating system telemetry data for Mist AI, which helps

achieve simpler operations, shorter mean time to repair (MTTR),

and streamlined troubleshooting. For more information, read the

Juniper Mist Wired Assurance datasheet.

In addition to Juniper Mist Wired Assurance, Marvis Virtual

Network Assistant—a key part of The Self-Driving Network™—

makes the Mist AI engine interactive. A digital extension of the IT

team, Marvis offers automatic fixes or recommended actions,

allowing IT teams to streamline how they troubleshoot and manage

their network operations.

EVPN-VXLAN Technology

Most traditional campus networks have a single-vendor, chassis-

based architecture that worked well for smaller, static campuses

with few endpoints. However, this approach is too rigid to support

the changing needs of modern campus networks. The EX4100

supports EVPN-VXLAN, extending an end-to-end fabric from

campus core to distribution to the access layer.

An EVPN-VXLAN fabric is a simple, programmable, highly scalable

architecture built on open standards. This technology can be

applied in both data centers and campuses for architectural

consistency. A campus EVPN-VXLAN architecture uses a Layer 3

IP-based underlay network and an EVPN-VXLAN overlay network.

A flexible overlay network based on a VXLAN overlay with an

EVPN control plane efficiently provides Layer 2 and/or Layer 3

connectivity throughout the network. EVPN-VXLAN also offers a

scalable way to build and interconnect multiple campus sites,

delivering:

• Greater consistency and scalability across all network layers

• Multivendor deployment support

• Reduced flooding and learning

• Location-agnostic connectivity

• Consistent network segmentation

• Simplified management
