7280R3A 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 flows. 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 7280R3A Series Accelerated sFlow feature the sampling and processing of flow 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 filters. 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.

Maximum Network Design Flexibility

•

Scalable designs with up to a 512-way ECMP provides flexibility and balances traffic evenly across the largest leaf-spine designs

•

MLAG designs are effective at almost any layer of the network and maximize cross-sectional bandwidth with fast failover times

measured in 100’s of milliseconds for link failures.

•

VXLAN gateway, bridging and routing with VMTracer features to enable next generation data center designs

•

Scalable routing tables to support internet route peering

•

Wide choice of dense 100G and 400G interfaces with broad support for flexible 10G, 25G, 50G or 200G modes.

•

Support for standards based IEEE 25GbE with mix and match support for simple and cost effective migration

•

Virtual output queue (VOQ) architecture and deep packet buffering to eliminate head of line blocking with low latency

•

ACL scalability with up to 100K entries per forwarding engine allows for rich policy control

•

Flexible allocation of L2 and L3 forwarding table resources for more design choice

•

PTP, Accelerated sFlow, DANZ and multi-port mirroring tools provide network wide visibility and monitoring to detect traffic bursts,

monitor latency and congestion and allow capacity planning to improve application performance and availability
