Description
Juniper EX9253 Switch Chassis – Manageable – 3 Layer Supported – Modular – Optical Fiber – 3U High – Rack-mountable – 1 Year Limited WarrantyThe 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.
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.
As a key component of Juniper’s Cloud-Enabled Enterprise architecture, EX9250 switches provide a simple, open, and smart approach to building enterprise networks. The EX9250 switches support Junos Fusion Enterprise technology, which enables a large number of devices deployed throughout a building to be managed as a single logical device. The EX9250 switches also support Data Center Interconnect (DCI), critical to workload mobility and application availability, by delivering leading technologies such as MPLS, virtual private LAN service (VPLS), and Ethernet VPN (EVPN).
EX9250 switches offer Evolved Enterprise Core capabilities that allow the creation of larger networks supporting both Layer 2 and Layer 3 application traffic. An Evolved Enterprise Core is enabled by combining technologies such as EVPN and Virtual Extensible LAN (VXLAN). EVPN uses control plane-based learning to ensure efficient network utilization and natively supports active/active multihoming. VXLAN overlay with EVPN allows L2 connectivity across the network while providing active/active redundancy, aliasing, and mass media access control (MAC) withdrawal. In an Evolved Enterprise Core, the provider edge (PE) switch/router can, in most cases, also use a VXLAN L3 gateway and route between VXLAN segments when required. Since the core is a standard IP network, EVPN/VXLAN allows the creation of an evolved core without having to replace the rest of the core infrastructure. Enabling an evolved core with EVPN provides flexibility by integrating with Junos Fusion and other technologies in the distribution/access layer, paving the way for a broader EVPN deployment over time.
