À propos du produit
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. The EX9250 Ethernet switches dramatically simplify campus and data center architectures by enabling Evolved Enterprise Core deployments with Junos Fusion Enterprise and Ethernet VPN, creating a path to a 100GbE core.
Product Description
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.
Custom Silicon
The EX9250 switches are based on Juniper One custom silicon, an ASIC designed by Juniper that provides a programmable Packet Forwarding Engine (PFE) and natively supports networking protocols such as virtualization using MPLS over IP and overlay network protocols. ASIC micro code changes, delivered through updates to Juniper Networks Junos® operating system, protect investments by allowing existing hardware to support new or future networking protocols.
