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,
