Data Sheet

Integrated R3-Series Switch

The integrated switch in the 7130LBR Series o ers a wide range of features for di erent applications. When connected directly to the

front-panel interfaces through the crosspoint, it provides high-performance switching and routing capable of 2.4 Tbps of throughput.

Its deep bu er virtual output queue (VOQ) architecture eliminates head-of-line (HOL) blocking and virtually eliminates packet drops

even in the most congested network scenarios. An advanced tra c scheduler fairly allocates bandwidth between all virtual output

queues while accurately following queue disciplines including weighted fair queueing, xed priority, or hybrid schemes. As a result, the

R3-Series switch can handle the most demanding data center requirements with ease, including mixed tra c loads of real-time,

multicast, and storage tra c while still delivering low latency.

Using the crosspoint to mirror front-panel tra c, the switch can also be used out-of-band for monitoring layer 1 paths or FPGA links,

saving valuable FPGA logic. In tap aggregation mode, the switch supports time stamping, tra c steering, and N:M mirroring with

arbitrary aggregation groups.

FlexRouteTM

The Arista FlexRoute Engine provides support for the full internet

routing table, in hardware, with IP forwarding at Layer 3 and with

su cient headroom for future growth in both IPv4 and IPv6 route

scale to more than 1.4 million routes. The innovative FlexRoute

Engine with its patented algorithmic approach to building layer 3

forwarding tables on Arista R-Series Universal Spine and Leaf

platforms is unique to Arista and a key enabler in calling these

platforms routers.

Accelerated sFlow

SFlow is a powerful tool used commonly by network operators for

advanced network telemetry, capacity planning, security analysis

and quality of experience monitoring. Traditional sFlow utilizes a

system CPU for processing samples of hundreds of thousands of

ows. In modern high performance systems guaranteed high rate

sampling requires the capability to both sample and process packet

rates of billions of packets per second. With the R-Series Accelerated

sFlow feature, the sampling and processing of ow samples into

sFlow datagrams is handled via integrated sFlow engines capable of

supporting 1:500 sampling rates on full wire speed systems or

higher rates with selective sampling based on triggers and lters. All

sFlow v5 information is included in the sFlow records ensuring

consistent integration with existing standard sFlow collection and

analysis tools and no loss of information.

In-band Network Telemetry

In-band network telemetry, or INT, is a standards-based approach to providing deep visibility into tra c in real-time, with no impact on

switch performance. INT provides per- ow monitoring of tra c drops, latency, congestion and the network path. INT information can

be exported in IPFIX or sFlow formats to a management system or collector such as Arista CloudVision, for predictive analytics and deep

forensics to measure latency per device and across the network, trace packets and reconstruct path topology as well as detecting hot-

spots. In-band Network Telemetry is available on the R-Series switch, with the ability to originate, pass and terminate, along with

mirroring to external collectors.
