DESIGNED FOR CONVERGED SERVICES
The convergence of traditionally non-LAN services on
top of growing ENTERPRISE applications brings greater demands,
responsibilities, and threats to the network infrastructure. The
Summit 400-24p, designed for convergence, provides the mandatory
resiliency to keep applications available, delivers the features
and performance to support converged services, and provides
unique protection from security threats.
Link Redundancy
Proper support for converged services requires link resiliency,
which the Summit 400-24p provides through an extensive set of
Layer 1 through Layer 3 link redundancy options, for example:
| • |
Layer 1: Software
redundant port, so simple and easy to deploy that it
requires no supporting protocols or timers to configure. |
| • |
Layer 2: Standard
spanning tree and rapid spanning tree, plus the EXTREMEly
fast convergence of EAPS which is capable of preserving
sessions of latency sensitive applications such as
voice-over-IP (VoIP) through link failure. |
| • |
Layer 3: OSPF
Equal Cost Multi-Path (ECMP) which doubles the throughput of
redundant links, VRRP for layer 3 dual homing, and ESRP
which supports dual homing at both Layer 2 and Layer 3. |
Rapid Convergence Resiliency
The Summit 400-24p provides Ethernet Automatic Protection
Switching (EAPS), the RFC 3619 link layer resiliency protocol
pioneered by EXTREME Networks. Since EAPS fails over in less
than 50 milliseconds in most deployments, the Summit 400-24p
recovers from faults without disrupting latency-sensitive
sessions such as VoIP calls. This ensures toll-quality voice and
picture-perfect video.
Redundant Power Supplies
The Summit 400-24p backs up its PoE with fully redundant EPS-LD
power supplies that sustain full class 3 PoE, undisturbed by
outages from a single power source. This assures that business
goes on, data is not disrupted, and critical converged services
are constantly present.
Quality of Service (QoS)
EXTREME Networks pioneered quality of service (QoS) over local
area networks, with every EXTREME Networks switch having been
built from the ground up to deliver superior QoS. The Summit
400-24p is no exception, with its eight hardware QoS queues for
finest granularity of prioritized traffic forwarding. Utilizing
the power of eight QoS queues is the packet intelligence of
EXTREMEWare®, which is able to examine packets from Layer 2 to
Layer 4 in the processes of classifying traffic. With a powerful
classification engine and fine queue granularity, Summit 400-24p
provides consistent and timely packet delivery required to
support converged services.
Minimized Latency
Latency and jitter can be lethal to real-time
applications such as voice and video. The Summit 400-24p was
designed around a low latency and low jitter architecture in
spite of the wealth of services it delivers. In particular, the
UniStack stacking architecture was designed so that forwarding
is always performed locally when the destination port is known,
and when packets have to pass through the stack they always take
the shortest path.
Non-Blocking Forwarding
High-performance starts with a non-blocking architecture as
delivered by the Summit 400-24p. Since any access switch that
properly supports converged services must also examine every
packet to for QoS and security, the ability to apply these
features without degrading switch performance is even more
important. The Summit 400-24p supports all security, QoS, and
management features at full line rate, with no negative effect
on applications.
Line Rate Access Control Lists (ACLs)
ACLs are one of the most powerful tools to control network
resource utilization and to secure and protect the network.
Summit 400-24p supports up to 1,512 ACLs based on Layer 2, 3 or
4-header information such as the MAC address, IP
source/destination address, or protocol.
Intelligent Network Access
Summit 400-24p supports a comprehensive range of Network Login
options by providing an 802.1x agent-based approach, a web-based
(agent-less) login capability for guests, and a MAC-based
authentication model for devices. With these modes of Network
Login, only authorized users and devices can connect to the
network and be assigned to the appropriate VLAN.
Multiple Supplicant Support
Multiple supplicant support secures IP telephony and wireless
access. Converged network designs often involve the use of
shared ports. Shared ports represent a potential vulnerability
in a network. Multiple supplicant capability on the Summit
400-24p switch allows it to uniquely recognize and apply the
appropriate policies for each user or device on a shared port.
Media Access Control (MAC)
The MAC address security/lockdown feature enables Summit 400-24p
to block access to any Ethernet port when the MAC address of a
station attempting to access the port is different from the
configured MAC address. This feature is used to “lock down” a
device like an IP telephone, an AP or a server to a specific
port.
Host Integrity Checking
Host integrity checking helps keep infected or non-compliant
machines off the network. Summit 400-24p supports a host
integrity or end point integrity solution that is based on the
Trusted Computing Group model.
Denial of Service (DoS) Protection
If a Summit 400-24p switch detects an unusually large number of
packets in the CPU input queue, it will assemble ACLs that
automatically stop these packets from reaching the CPU. After a
period of time, the ACLs are removed. If the attack continues,
they are reinstalled.
MD5 Authentication of Routing Protocols
MD5 authentication of routing protocols prevents attackers from
tampering valid messages and attacking routing sessions.
The Summit 400 series of switches
allows the traditional edge layer and aggregation layer of
the network to be collapsed into a single access layer. A
two-tier network that consists of an access layer and a core
layer can reduce the number of switches required and hence
reduce the network acquisition costs and network management
costs. Depending on the size and geographic reach of the
network, a two-tier network can be the most cost-effective
design for a corporate network. The Summit 400 series of
switches are also designed to reduce CapEx and OpEx as
demonstrated by the following features:
|
• |
All Summit 200s, 300s, and 400s
share the same operating system and network management
software thereby simplifying the management of the
access layer |
|
• |
The stackable Summit 400 family
provides the convenience of a chassis at the price point
of stackable switches |
|
• |
Modular External Power System with
simple plug and play installation makes upgrading or
maintaining redundant power on the Summit 400 family
easy |
|
UNIFIED ACCESS FOR WIRED AND WIRELESS
Networks are undergoing a transition from simple Fast
Ethernet data connectivity to converged services and new
applications over LAN, which demand new infrastructure services:
PoE, wireless access support, Gigabit Ethernet to the desktop,
or all of these. The Summit 400-24p provides all of these
services in one multi-dimensional platform.
Legacy Support
With plug-and-play auto-sense on every port, attaching legacy
devices is easy. With the Summit 400-24p, existing 10 Mbps or
100 Mbps devices are transparently supported, and new security
and management benefits become immediately available.
Gigabit Evolution
Gigabit Ethernet is a mature technology that provides the
highest available bandwidth to the desktop. The combination of
low-cost Gigabit Ethernet NICs and embedded gigabit interfaces,
and ever more bandwidth hungry ENTERPRISE applications, is
driving the demand for gigabit to the desktop for which the
Summit 400-24p is the perfect switch, with its line-rate Layer 2
and Layer 3 forwarding, and QoS and resiliency to support for
demanding applications.
Future Applications
The Summit 400-24p already provides low latency and jitter plus
the ability to prioritize based on an extended set of packet
header information that the most challenging of future
applications is likely to present. This combination of
performance plus packet intelligence, coupled with line rate
forwarding and support for powered devices, makes the Summit
400-24p an easy choice to future-proof the LAN access layer for
future converged applications such as IP telephony.
Security
Excellent wireless support starts with excellent security, and
the Summit 400-24p provides industry-standard security
capabilities including flexible authentication options like:
| • |
Hardware
accelerated RC4 and AES encryption |
| • |
Reliable
authentication with multiple supplicant Network Login, both
802.1x and browser-based, that won’t allow unauthenticated
LAN access |
| • |
MAC security to
link and lock a device to its port |
| • |
Perimeter defense
through rogue access point detection that foils attempts to
bypass security |
| • |
Thin wireless
access points to prevent thefts of critical security
parameters |
Mobility
Mobile applications such as hospital patient care equipment,
retail POS or inventory devices, Voice over Wireless LAN (VoWLAN)
phones, or handheld PDAs require quality of service and the
ability to roam between access points. The Summit 400-24p
provides seamless transfer between access points. This enables
users to gain productivity while flexibly moving throughout the
facility.
Availability
To assure constant availability of wireless access, the Summit
400-24p provides a plethora of redundancy features including
common spanning tree and rapid spanning tree that are commonly
provided, and much more. For example, Software Redundant Port
makes one link redundant to another very simply, with no
protocol overhead. For latency sensitive applications, EAPS is
capable of failing over in 50 milliseconds, fast enough to
sustain a VoIP session. At Layer 3 there are three more options:
OSPF ECMP, VRRP, and ESRP, for incredibly scalable deployment of
link resiliency.
Telecommunications Over LAN
Deployments of IP telephony depend on reliable consistent power
from the Ethernet jack. Analog phones are similarly line
powered, a feature that centralizes power and simplifies
providing redundant power. The Summit 400-24p is the basis for a
reliable LAN telephony infrastructure, with fully redundant 15.4
watts per port, and QoS and resiliency to match the failover
requirements for latency-sensitive services like voice over IP (VoIP)
phones.
Voice Grade Connections
Granular QoS, low latency, and low jitter enable voice quality
connections. Summit 400-24p supports a range of QoS technologies
that can prioritize and predictably handle high priority
traffic—policing or rate limiting on ingress, 802.1q tagging and
DiffServ marking, and shaping on egress with eight queues per
port. The EXTREME Networks tradition of building products with
low latency and jitter continues with the Summit
400-24p—allowing network managers to build networks with low
end-to-end latency and jitter.
Deployment Simplicity
Wireless APs and security devices such as card readers and
security cameras are commonly deployed in locations where it is
inconvenient and costly to deploy redundant, reliable power.
With the Summit 400-24p, deployment of powered LAN devices is
quick and easy with its support of the IEE 802.3af standard and
full Class 3 power availability on all ports, backed up 100% by
the EPS-LD redundant power supply.
Unified Access Architecture (UAA)
UAA features are supported by Summit 400-24p so that ENTERPRISEs
can implement a single, secure and seamless network for wired
and wireless network access, rather than having to operate two
separate or parallel networks.
Universal Access Port
The Summit 400-24p offers the Universal Access Port ö
high-performance gigabit to the desktop, PoE, and wireless
support from every RJ45 port. Installing universal services
ports everywhere for data and device power greatly simplifies
installations and moves and future-proofs your edge network. The
Summit 400-24p provides universal attachment at any desktop
Ethernet speed, any power level from none to full 15.4 watts,
with support for wired or wireless access.
Unified Access Architecture, the innovative edge
architecture from EXTREME Networks, is designed for
ENTERPRISEs that need a single, secure and seamless network
for both wired and wireless network access, rather than
having to operate two separate or parallel networks. Through
this unified approach, you have the freedom to extend your
network edge for wireless access, LAN telephony, PDAs and
other devices without compromising security, scalability,
availability, mobility or management. UAA implements our
vision of a universal port on the wall to which you can
connect a traditional PC, an IP telephone or a lightweight
access point.
UAA centralizes the management and
operation of wired and wireless networks into the wiring
closetâs Layer 3 access switches, on both fixed form factor
and chassis based products. The universal Ethernet jack is
designed to deliver consistent security, user authentication
and QoS policy for a multitude of devices that access the
network using wired or wireless media.

SIMPLIFIED MANAGEMENT
Network management and maintenance can be
challenging, especially for IT departments managing complex
converged networks while under the pressure to reduce staff and
expenses. For all organizations, any repetitive management
operation taxes skilled resources, draining valuable
productivity. The Summit 400-24p offers relief through the
management simplification provided by UniStack stacking. By
making a stack of switches appear to be a virtual modular
switch, the EXTREMEWare UniStack architecture allows all ports
in the stack of switches to be configured in one management
session.
Single Point of Management
With UniStack, up to eight EXTREME Networks Summit
switches—including the Summit 400 and Summit 200 families and
the Summit 300-24—appear as a single network element managed
through a single IP address, with the stack representing a
single managed object inside an ENTERPRISE management tool such
as EPICenter® management suite from EXTREME Networks. Having a
single IP address for configuration, changes and upgrades
reduces complexity and saves time.
Easy Adds/Drops
UniStack stacking simplifies network expansions or changes.
Adding new access ports to the LAN is as simple as turning on
stacking in a new Summit 400-24p and adding it to an existing
stack, similar to adding a new module to a modular switch,
except that no space-consuming chassis is required. Similarly,
moving the Summit 400-24p to a new location is convenient, since
the transferred switch can stand alone or become part of another
stack.
Simple Redundancy Enhancement
Because a stack of Summit 400-24ps represents an n-times
replication of traffic processors, management processors, memory
and power supplies, the net resiliency of a UniStack stack is
greater than the sum of its parts. Add to this the ability to
distribute redundant uplinks on different switches and
availability goes up even more, compared to a standalone switch.
Highly Reliable Architecture
UniStack stacking on Summit 400s is a highly resilient
bi-directional full-duplex ring architecture with n-1 stack
master redundancy designed to survive the failure of a stacking
link or switch in the stack. With a nominal transfer rate of 20
gigabits per second (Gbps) and instantaneous transfers of 40
Gbps per switch, a stack of eight switches can transfer up to
160 Gbps through the stack with highly reliable, completely
distributed, shortest path forwarding.
Common Command Line Interface (CLI) Edge to Core
The Summit 400-24p operates with the awardwinning EXTREMEWare
software. EXTREMEWare gives the Summit 400-24p the same
administrative interface as any EXTREMEWare switch running in
the network. This common interface reduces training time, time
to configure or update, and management overhead.
Common Feature Set
The common feature set that the Summit 400-24p shares with other
EXTREME Networks switches, controlled by license levels,
simplifies and reduces the cost of managing an EXTREME Networks
powered LAN. The Summit 400-24p delivers a rich suite of
features spanning the range of protocols to intelligently
overseeing traffic, consistent and simple to deploy, enabling
efficient, productive LAN management.
Common Management
EXTREME Networks EPICenter® ENTERPRISE LAN manager supports the
Summit 400-24p, either individually or in UniStack stacks,
providing a global view to enhance IT staff productivity.
Whether the LAN is managed via serial port, web, telnet or a
network manager like EPICenter, EXTREMEWare included with the
Summit 400-24p provides a uniform interface for common
management, thus reducing the cost of management.
Link Layer Discovery Protocol
By incorporating LLDP, the Summit 400-24p reduces networking
expenses by enabling plug and play installation of network
devices, simplifying maintenance and reducing troubleshooting
time. With its support of IEEE 802.1ab LLDP simplifies
deployment of VoIP phones, wireless access points, cameras, and
any device that supports this vendorindependent protocol.
Integrated Wireless Management
The Summit 400-24p Advanced Edge feature set includes integrated
wireless management to configure, control, and secure the
wireless portion of the LAN. When used with EXTREME Networks
Altitude APs it provides a high level of assurance that the LAN
is secure from intrusion and security breaches. For example,
rogue access points can be detected, located, and de-activated
using the CLI and/or EPICenter.
Desktop Access Management
Using ACLs to examine Layer 2, 3, and 4 packet header
information for security and traffic classification, establishes
the Summit 400-24p as a premier access switch. Its ability
authenticate users essential at the LAN edge, separates the
Summit 400-24p from the pack. These features and more, available
in the EXTREMEWare operating system shipped with the Summit
400-24p, provide the full and robust access management that sets
Summit 400-24p apart from others.
Power Management
Summit 400-24p provides a concise feature set to manage PoE.
Before providing power it can automatically discover PoE devices
and their class level, and provide the right amount of power. It
can allow or disallow devices that don’t comply with the IEEE
802.3af standard and power cycle a device attached to a port
without disrupting data flow through the port. Administrators
can set port power limits or just allow them to be automatically
derived, with confidence that defective devices will be powered
down if they exceed budget.
Secure Management
The use of protocols like SSH2, SCP and SNMPv3 supported by
Summit 400-24p prevents the interception of management
communications and man-in-the middle attacks.
