The Summit 300

series switches

enable high quality

VoWLAN with

leading handsets

such as SpectraLink.

For PoE, the switch generates up to 15.4

watts of PoE for devices such as VoIP

phones, surveillance cameras, badge

readers, Extreme Networks Altitude APs

and “fat” APs sold by other vendors. When

used with Altitude APs, Summit 300 series

switches provide wireless performance as

each AP simultaneously broadcasts both

802.11a and 802.11b/g. Extreme Networks

has also implemented the SpectraLink

Voice Protocol, a QoS standard used by

the leading WLAN handsets today for

recognizing and prioritizing voice packets.

When enabled in tandem with the Inter-

Access Point Protocol which allows Layer

2 roaming between APs, Voice over

Wireless LAN (VoWLAN) users can

productively communicate with

customers,

patients,

emergency

personnel and

employees

anytime within

a facility.

Compared to other vendors’ point

solutions, Summit 300 series switches

offer a low Total Cost of Ownership

because they are fully integrated into

Extreme Networks family of edge,

aggregation, and core end-to-end solu-

tions. ExtremeWare Layer 2 and

Layer 3 features implemented in the

Summit 300 series switches are shared

with all other Extreme Networks platforms

in the Summit product line as well as with

Alpine

and BlackDiamond

switches.

From a PoE/wireless perspective,

Summit 300 series switches are comple-

mentary to the BlackDiamond 8800 series

PoE blade, and the Alpine 3800 PoE blade.

Each of these switches supports UAA,

providing a seamless infrastructure for

voice and data support on both wired and

wireless networks. EPICenter manage-

ment platform makes it easy to develop

centralized conﬁguration and management

policies throughout the network. The

Summit 300 series switches also uses the

same Command Line Interface (CLI) and

the same management commands as other

Extreme switches so training time and

expense are reduced as operational

expertise can be shared over an entire

network solution.

Extreme Networks Data Sheet

Beneﬁts

Summit 300 Series Beneﬁts

High-Performance

Non-blocking wire-speed architecture

helps ensure performance for demand-

ing wired and wireless applications.

Extreme Networks Altitude APs support

802.11 a, b, and g, today’s fastest

wireless LAN (WLAN) standards.

Extraordinary Availability

Redundant copper and ﬁber gigabit

uplinks, dual-homed conﬁgurations,

and sub-second EAPS failover provide

mission-critical resiliency. The switch

continuously monitors “heartbeats”

generated by the Altitude APs, helping

to ensure more continuous wireless

user operation.

Industry-leading Security

UAA from Extreme Networks provides a

single wired/wireless authentication

infrastructure for consistent, policy-

based security from the edge to the core.

Wireless security includes hardware-

accelerated AES and RC4 encryption.

Extreme Networks also offers rogue AP

detection for defending the wireless

perimeter of a network.

Scalability

The Summit 300 series switches provide

PoE to every port for voice, video, data

or wireless devices.

End-to-End Manageability

As a member of Extreme Networks’

comprehensive family of switches, the

Summit 300 series switches can be

centrally deployed, managed, and

monitored using EPICenter

manage-

ment platform from Extreme Networks or

any SNMP-based products. In addition,

Extreme Networks offers the RF Manager

site survey tool for simpliﬁed wireless

design and its AccessAdapt™ utility for a

no-conﬁguration installation of the

Altitude APs.

High-Performance with QoS

for Converged Applications

With its non-blocking architecture the

Summit 300 series switches enable all

RJ-45 copper 10/100 ports to operate at

line-rate. Four hardware queues per

10/100 port provide granularity, low

latency and low jitter for time-sensitive

voice and multi-media applications.

These applications also beneﬁt from

features such as DiffServ and 802.1p

which deliver varied levels of service and

ensure efﬁcient bandwidth usage. Copper

and SFP GBIC Gigabit Ethernet uplink

ports can be conﬁgured as active and

redundant for fast Layer 1 failover. These

uplink ports provide the added ﬂexibility

of port redundancy between copper and

ﬁber ports, enabling backup links to the

active uplinks with sub-second (50ms)

failover capability through EAPS.

The Summit 300 series switches offer a

number of features that improve the

performance of the network, such as RIP,

OSPF, Network Address Translation, QoS

classiﬁcation, dynamic VLANs, and ACLs.

For converged applications involving

voice or rich media, the switch provides

multicast, re-writing 802.1p tag prioritiza-

tion, or prioritization using Layer 2/3/4.

Rate shaping can be used for optimum

VoIP performance.

The Summit 300 series switches deliver

advanced high availability features

traditionally reserved for carrier net-

works. EAPS (RFC 3619) delivers sub-

second (less than 50ms recovery)

protection switching to interconnected

switches in an Ethernet ring topology.

Similar to the Spanning Tree Protocol

(STP), EAPS offers the advantage of

converging in signiﬁcantly less time than

STP or even Rapid Spanning Tree

(802.1w) when a link breaks in the ring.

Extreme Standby Routing Protocol™

(ESRP) can be implemented at both

Layers 2 and 3 and extends the Virtual

Redundant Redundancy Protocol’s

(VRRP) capabilities, adding Layer 2

resiliency and loop prevention and Layer

3 default router redundancy. It can be

used as a STP substitute and can be

scaled to protect thousands of VLANs.

Multiple instances of ESRP in the same

VLAN allow direct host attachment to

standby switches.

Equal Cost Multipath adds network

resiliency as multiple equal-cost routes

can be used concurrently to an end

destination. With the software redundant

port feature, a speciﬁed primary port can

be backed up by another port. Should the

link go down on the primary port, the

redundant port will establish a link and

become active. Thus multi-homed

redundancy can be easily designed

without the implementing complexity of

a protocol.
