Description
Features
Compact Form Factor
Shallow depth 1 U and 3 U form factors are ideal for space-constrained enterprise campus closet environments.
End-to-End Network Segmentation
End-to-end network segmentation goes from campus to data center with open Ethernet VPN (EVPN) technology.
EVPN-VXLAN allows the creation of an evolved core without having to replace the rest of the core infrastructure.
Campus Fabric
Switches are connected as an IP fabric with an EVPN-VXLAN overlay. The IP fabric can extend to connect multiple enterprise buildings, while VXLAN allows stretching L2 across the network.
EVPN uses control plane-based learning to ensure efficient network utilization and natively supports active/active multihoming.
MACsec AES256 Support
Support for IEEE 802.1ae (MACsec AES256) for link-layer data confidentiality, data integrity, and data origin authentication.
The EX9253-12C8Q-M line card supports IEEE 802.1ae MACsec with AES-256 bit encryption, ensuring link-layer data confidentiality, data integrity, and data origin authentication.
Field-Proven Juniper Technology
Field-proven Juniper technology—including high-performance ASICs, a cloud-grade architecture, and Junos OS—enables EX Series Ethernet Switches to provide always-on reliability for every application.
The EX9250 line of Ethernet switches provides compact, programmable, and scalable core and aggregation devices for enterprise environments, reducing cost and complexity while offering carrier-class reliability.
Architectural Flexibility
Supports EVPN/VXLAN, IP Fabric, and multichassis link aggregation group (MC-LAG) for Layer 2 and Layer 3 networks, delivering the flexibility needed to quickly deploy and support new services.
Precision Time Protocol
Supports financial trading and time-stamping packets for synchronization.
Overview
The EX9250 line of Ethernet switches provides compact, programmable, and scalable core and aggregation devices for enterprise environments, reducing cost and complexity while offering carrier-class reliability.
EX9250 switches empower organizations to deploy an evolved enterprise core, supporting layer 2 or layer 3 applications by combining Ethernet VPN (EVPN) and Virtual Extensible LAN (VXLAN) technologies. Using these open technologies allows enterprises to create a coherent, end-to-end network across geographically dispersed locations while leveraging unified policies to segment traffic.
