EX9250 Line of Ethernet Switches
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.
Features + Benefits
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.
Secure 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.
MACsec AES256 Support
Support for IEEE 802.1ae (MACsec AES256) for 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 Juniper Networks® EX9250 line of compact, programmable, and scalable Ethernet switches is ideal for aggregating access switches such as Juniper Networks EX2300, EX3400, EX4300, and EX4600 Ethernet Switches deployed in campus wiring closets and in on-premises data centers.
The EX9250 is also a key component of Juniper’s AI-Driven Enterprise. The switch decouples the overlay network from the underlay with technologies such as Ethernet VPN (EVPN) and Virtual Extensible LAN (VXLAN), addressing the needs of the modern enterprise network by allowing network administrators to create logical L2 networks over different L3 networks.
Two EX9250 chassis options are available, providing considerable deployment flexibility:
- EX9251 Ethernet Switch is a fixed-configuration 1 U chassis that supports 8-port 1GbE/10GbE and 4-port 40GbE/100GbE.
- EX9253 Ethernet Switch is a two-slot modular 3 U chassis that supports any combination of the following line cards:
- EX9253-6Q12C, a 12-port QSFP28 40GbE/100GbE and 6-port QSFP+ 40GbE line card
- EX9253-6Q12C-M, a 12-port QSFP28 40GbE/100GbE and 6-port QSFP+ 40GbE line card with Media Access Control Security (MACsec) support
Fully configured, a single EX9253 chassis can support up to 144 10GbE ports (all at wire speed), delivering one of the industry’s densest line-rate 10GbE port densities for this class of feature-rich and programmable switch. The EX9253 switch is capable of delivering up to 2.4 Tbps per slot.
