Dynamic, Flow-Based Packet Classiﬁcation

Another unique feature that separates the

Enterasys S-Series from all competitive

switches is the capability to provide User-

Based Multi-layer Packet Classiﬁcation/QoS.

With the wide array of network applications

used on networks today, traditional Multi-

layer Packet Classiﬁcation by itself is not

enough to guarantee the timely transport of

business-critical applications. In the S-Series,

User-Based Multi-layer Packet Classiﬁcation

allows trafﬁc classiﬁcation not just by packet

type, but also by the role of the user on

the network and the assigned policy of that

user. With User-Based Multi-layer Packet

Classiﬁcation, packets can be classiﬁed based

on unique identiﬁers like “All Users”, “User

Groups”, and “Individual User”, thus ensuring

a more granular approach to managing and

maintaining network conﬁdentiality, integrity,

and availability.

Network Visibility From High Fidelity NetFlow

Network performance management and security capabilities via NetFlow are available on every Enterasys S-Series switch port without slowing down

switching and routing performance or requiring the purchase of expensive daughter cards for every module. Enterasys NetFlow tracks every packet in

every ﬂow as opposed to competitor’s statistical sampling techniques or restrictive appliance-based implementations. The value of unsampled, real-time

NetFlow monitoring is the visibility into exactly what trafﬁc is traversing the network and if something abnormal occurs it will be captured by NetFlow

and appropriate action can be applied. Additionally, NetFlow can be used for capacity planning allowing the network manager to monitor the trafﬁc

ﬂows and volumes of trafﬁc in the network and understand where the network needs to be reconﬁgured or upgraded. This will save time and money,

by enabling administrators to know when and where upgrades might be needed. The S-Series ﬂow monitoring capabilities are industry leading, it can

concurrently monitor in excess of 70,000 ﬂows per second, a far greater capacity than any other vendors switch or router.

Feature Summary

Uniﬁed Cross-Platform Operating System

The Enterasys S-Series ﬁrmware adds the beneﬁt of becoming a multi-platform operating system that uniﬁes the Enterasys N-Series and S-Series into

a single ﬁrmware image that operates on both platforms ensuring feature parity and consistent operation across the ﬂow-based switches. This provides

many customer beneﬁts: reduced TCO via a single, uniﬁed operating system from network edge/access layer to the network core and data center, feature

and function consistency across platforms, and easy deployment and upgrades to ensure operational efﬁciency.

Integrated Services Design

Integrated services design is a key differentiator that separates the Enterasys S-Series from the competition. Integrated services design reduces the

number and type of modules required to build typical wiring closet conﬁgurations, simplifying the overall network design. In turn, this signiﬁcantly

reduces the maintenance and sparing cost as each I/O fabric or I/O module can perform all of these services, unlike competitive offerings with multiple

dedicated module types for each speciﬁc service.

Multi-layer packet classiﬁcation - enables the delivery of critical applications

to speciﬁc users via trafﬁc awareness and control

• User, Port, and Device Level (Layer 2 through 4 packet classiﬁcation)

• QoS mapping to priority queues (802.1p & IP ToS/ DSCP) up to 16 queues per port

• Multiple queuing mechanisms (SPQ, WFQ, WRR, and Hybrid)

• Granular QoS/rate limiting

• VLAN to policy mapping
