Features and Benefits

Wired Service Level Expectations

The Wired Assurance feature provides operational visibility into the

wired experience with service-level expectations (SLEs) for EX

Series Switches. Pre- and post-connection performance metrics

help you monitor successful connects and switch health throughout

the system, using Mist AI to measure and manage networks and

simplify troubleshooting.

Automation

The EX4650 supports a number of network automation and plugand-

play features, including ZTP and event scripts, automatic

rollback, and Python scripting.

Flexible Forwarding Table

The EX4650 includes a Unified Forwarding Table (UFT), which

allows the hardware table to be divided into configurable partitions

of L2 media access control (MAC), L3 host, and longest prefix

match (LPM) tables. In a pure L2 environment, the EX4650

supports up to 288,000 MAC addresses; in L3 mode, the table can

support up to 168,000 host entries; in LPM mode, the table can

support up to 360,000 prefixes. Junos OS provides configurable

options through a CLI to optimize the EX4650 for various

deployment scenarios.

Intelligent Buffer Management

The EX4650 features a total of 32 MB of shared buffers. While

25% of the total buffer space is dedicated, the rest is shared among

all ports and is user configurable. The intelligent buffer mechanism

in the EX4650 effectively absorbs traffic bursts while providing

deterministic performance, significantly increasing performance

over static allocation.

MPLS

A broad set of MPLS features, including L3 VPN, IPv6 provider

edge router (6PE), RSVP traffic engineering, and LDP, support

standards-based network segmentation and virtualization, allowing

the EX4650 to be deployed as a low-latency MPLS label-switching

router (LSR).

VXLAN Overlays

The EX4650 is capable of both L2 and L3 VXLAN gateway services.

Customers can deploy overlay networks to provide L2 adjacencies

for applications over L3 fabrics. The overlay networks utilize

VXLAN in the data plane and EVPN for programming the overlays,
