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 labelswitching

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
