Description
QFX5110-48S-AFO Overview
QFX5110 access and aggregation switches deliver low latency, rich Layer 2 and Layer 3 features, VXLAN overlay deployments, and 100GbE uplinks, making it the industry’s most nimble line of switches.
Featuring L3 gateway capabilities for bridging between virtualized and bare-metal servers, the QFX5110 is designed for extremely agile data centers that demand support for overlay/underlay network architectures. The high-density 10GbE, 40GbE, and 100GbE ports also make the QFX5110 ideally suited for use in spine and leaf topologies.

Product Details
The QFX5110-48S-AFO provides these features and benefits:
* Automation—The QFX5110 switches support a number of features for network automation and plug-and-play operations. Features include zero touch provisioning, operations and event scripts, automatic rollback, and Python scripting. The switch also supports integration with VMware NSX Layer 2 Gateway Services, and OpenStack.
* Flexible Forwarding Table—The QFX5110 includes a Unified Forwarding Table (UFT), which allows the hardware table to be carved into configurable partitions of Layer 2 media access control (MAC), Layer 3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the QFX5110 supports 288,000 MAC addresses. In Layer 3 mode, the table can support 208,000 host entries. In LPM mode, it can support 128,000 prefixes. Junos OS provides configurable options through a CLI so that each QFX5110 can be optimized for different deployment scenarios.
* Intelligent Buffer Management—The QFX5110 switches have a total of 16 MB shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the QFX5110 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.
* MPLS—QFX5110 switches support a broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP to allow standards-based network segmentation and virtualization. This enables the QFX5110 to be deployed as a low-latency MPLS label-switching router (LSR).
* VXLAN Overlays—The QFX5110 switch is capable of supporting Layer 2 and Layer 3 gateway services. Customers can deploy overlay networks to provide Layer 2 adjacencies for applications over Layer 3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN or OVSDB to program the overlays. The overlays can operate without a controller, or they can be orchestrated with an SDN controller.
