Junos Operating System

The EX4100 switches run Junos OS, Juniper’s powerful and robust

network operating system that powers all Juniper switches, routers,

and firewalls. By utilizing a common operating system, Juniper

delivers a consistent implementation and operation of control plane

features across all products. To maintain that consistency, Junos OS

adheres to a highly disciplined development process that uses a

single source code and employs a highly available modular

architecture to prevent isolated failures from bringing down an

entire system.

These attributes are fundamental to the core value of the software,

enabling all Junos OS-powered products to be updated

simultaneously with the same software release. All features are fully

regression tested, making each new release a true superset of the

previous version. Customers can deploy the software with

complete confidence that all existing capabilities are maintained and

operate in the same way.

Flex Licensing

Juniper Flex licensing offers a common, simple, and flexible

licensing model for EX Series access switches, enabling customers

to purchase features based on their network and business needs.

Flex licensing is offered in Standard, Advanced, and Premium tiers.

Standard tier features are available with the Junos OS image that

ships with EX Series switches. Additional features can be unlocked

with the purchase of a Flex Advanced or Flex Premium license.

The Flex Advanced and Flex Premium licenses for the EX Series

platforms are class-based, determined by the number of access

ports on the switch. Class 1 (C1) switches have 12 ports, Class 2

(C2) switches have 24 ports, and Class 3 (C3) switches have 32 or

48 ports.

The EX4100 switches support both subscription and perpetual Flex

licenses. Subscription licenses are offered for three- and five-year

terms. In addition to Junos OS features, the Flex Advanced and Flex

Premium subscription licenses include Juniper Mist Wired

Assurance. Flex Advanced and Flex Premium subscription licenses

also allow portability across the same tier and class of switches,

ensuring investment protection for the customer.
