Choosing the best campus switches for your network environment
A collection of articles that takes you from defining technology needs to purchasing options
Juniper Networks Inc. offers a range of Ethernet network switches that can be deployed in branch offices, data centers and campus environments. At the heart of Juniper Networks' campus LAN switch product line is its highly modular Junos operating system used in the EX Series switches, routers and security products. Junos also supports the open software customers want as they move to software-defined networking and cloud architectures.
Juniper EX switch options from the access layer
The EX2200 series offers Layer 2 and basic Layer 3 capabilities, including static routing. These 1U, fixed-port switches can be ordered with 24 or 48 10/100/1,000 RJ45 Gigabit Ethernet (GbE) interfaces, with or without Power over Ethernet plus support for up to 30 watts per port. In terms of uplinks, each Juniper EX switch has 4x small form-factor pluggable (SFP) ports that can provide up to 1 Gbps each or a combined 4 Gbps uplink when channeled. Stacking in the Juniper world is known as virtual chassis. Up to four EX2200 switches can be combined to form a single virtual chassis for management. The switches can be connected using one or more of the available SFP interfaces on the switch.
The EX4200 series provides a fixed access switch for high-performance campus LAN deployments. These switches provide numerous capabilities beyond the EX2200 series, including Layer 3 routing, advanced quality of service, access and security, as well as the option for 10 Gbps copper or fiber uplinks using SFP+ interfaces. These switches also include advanced hardware high-availability features, such as hot-swappable power supplies and replicable fan trays. The EX4200 can be combined into a 10-switch virtual chassis.
What these switches provide for the core and distribution layer
The EX4600 series provides a low-cost, highly capable campus LAN switch for the distribution or collapsed core layer. These 1U switches offer interface flexibility, including the option to have up to 40 1 GbE, 72 10 GbE or 12 40 GbE interfaces using SFP, SFP+ or quad small form-factor pluggable plus slots. The EX4600 can handle throughput up to 1.44 Tbps. These campus LAN switches also support Juniper's virtual chassis technology, and up to 10 EX4600 switches can be combined into a single virtual chassis stack.
The EX9200 series provides a modular switch capable of handling traffic for large enterprise distribution and core layers. This switch also serves as the foundation for Juniper's Junos Fusion Enterprise, an aggregation architecture approach that allows for the virtual management of remote satellite switches using a single-pane-of-glass interface. These switches come in either four-, eight- or 14-modular slot chassis forms and can process 1.6, 4.8 or 13.2 Tbps on the backplane, depending to the chassis size. The switch can be configured with redundant routing engines for enhanced, high-availability capabilities, or two chassis can be combined using first hop redundancy protocols for even better performance and reliability.
Juniper EX switch pricing and support
All Juniper Networks' products and support contracts must be purchased through registered resellers. Depending on the switches purchased and the markup from the reseller, prices and default warranty will vary. For example, the EX2200 switches are covered under a limited lifetime warranty, with a replacement commitment between one and 20 days, depending on the campus LAN switch and warranty that switch falls under. Software patches are available for 90 days from purchase. Higher-end Juniper EX switches have shorter warranty structures. Juniper offers additional warranties, service-level agreements or technical support contract options.
