Description
QFX5120-48Y-AFI Overview
Native 25GbE with 100GbE uplink ports on the QFX5120- 48Y, combined with 32 ports of 100GbE on the QFX5120- 32C, make the QFX5120 family ideal for leaf-and-spine network deployments.
Featuring L3 gateway capabilities for routing between virtualized and bare-metal servers, the high-performance Juniper Networks QFX5120 Ethernet Switch provides the ideal foundation for dynamic data centers. Native 25GbE fiber ports on the QFX5120-48Y and 10GbE copper ports on the QFX5120-48T satisfy the growing demand for server access speeds, while high-density fixed-configuration 100GbE ports on the QFX5120-32C satisfy the need for compact, lower power devices in the spine. The QFX5120 is packed with software features that support traditional fabric designs with multichassis link aggregation (MC-LAG) or evolving SDN architectures with Ethernet VPN (EVPN)/Virtual Extensible LAN (VXLAN) on IP fabric underlays.
