Automation
Advanced Capabilities in Junos OS
Virtual chassis
Intelligent buffer management

The QFX5120 supports a number of network automation and plug-and-play operational features, including ZTP and event scripts, automatic rollback, and Python scripting.

The switch runs Junos OS, Juniper’s powerful and robust network operating system that powers all Juniper switches, routers, and firewalls. It supports advanced network features such as nonstop active routing (NSR).

The QFX5120 supports Juniper Networks’ unique virtual chassis technology, which enables up to two interconnected switches to operate as a single, logical device with a single IP address. This technology allows campus enterprises to eliminate STP and efficiently utilize network links.

The switch features a total of 32 MB of shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. It effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.
