Exceptional Policy-based QoS
with Advanced Traffic
Management for Converged
Applications
Summit X250e provides eight hardware
queues per port to support granular traffic
classification with bandwidth allocation.
1,024 centralized classifiers per 24-port
block can use information from Layers 1
through 4 to prioritize and meter incoming
packets at line-rate. When metering traffic,
the switches can drop out-of-spec traffic or
flag it for later action. To expedite upstream
traffic handling, a packet’s classification
can be carried forward with Layer 2 (802.1p)
and Layer 3 (Diffserv) markings.
Summit X250e provides advanced traffic
management features that support the
high-quality triple play of voice, video and
data services.
Efficient Management to
Handle Convergence-Driven
Network Changes
Universal Port—VoIP Auto-
Provisioning
Summit X250e sets the stage for conver-
gence applications by allowing enterprises
to add new access devices in a non-disrup-
tive plug-and-play fashion. Voice and
wireless services can be easily implement-
ed without major network upgrades.
Summit X250e supports the automated
provisioning of VoIP using Link Layer
Discovery Protocol (LLDP) and the
event-based command scripting capability.
It allows dynamic configuration of voice
VLANs and QoS. This auto-configuration
capability allows you to configure VoIP
phone settings such as voice VLAN settings,
call server IP address configuration, etc.
(see Figure 3). This level of simplicity in
managing network changes can reduce
operating expenses.
Power over Ethernet
Deployments of IP Telephony depend on
reliable, consistent power from the
Ethernet jack. Summit X250e-24p and
Summit X250e-48p are the basis for a
reliable LAN telephony infrastructure
with fully redundant resiliency to match
the failover requirements for latency-sen-
sitive services like VoIP phones. With
Summit X250e-24p or 48p, deployment of
powered LAN devices is quick and easy
with its support of the IEEE 802.3af
standard and full Class 3 power availability
on all ports, backed up 100% by the
EPS-500 redundant power supply
(Summit X250e-24p). Summit X250e-48p
can provide up to 370W of PoE power and
can be increased up to 740W of PoE power
to provide full 15.4W Class 3 devices on all
48 ports by adding an External Power
System (EPS-C and EPS-600LS).
Voice-Grade Connections
Granular QoS, low latency and low jitter
enable voice-quality connections.
Summit X250e 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 X250e series.
Comprehensive Network
Management
As the network becomes a foundation of
the enterprise application, network
management becomes an important piece
of the solution. Summit X250e supports
comprehensive network management
through Command Line Interface (CLI),
SNMP v1, v2c, v3 and an embedded
XML-based Web User Interface,
ExtremeXOS
ScreenPlay
™
. With a variety
of management options and consistency
across other Extreme Networks modular
and stackable switches, Summit X250e series
switches can provide ease of management
for demanding converged applications.
Extreme Networks has developed tools
that help save you time and resources in
managing your network. EPICenter
®
management suite provides fault, configuration,
accounting, performance and security
functions, allowing more effective
management of Extreme Networks multi-
layer switching equipment in a converged
network.
Advanced Routing Capabilities
for the Edge
Summit X250e supports advanced protocols
for an efficient and productive network.
Summit X250e switches provide static and
RIP routing for simple IPv4 and IPv6 Layer 3
deployment. An optional ExtremeXOS
Advanced Edge license extends the feature
set to include other important edge
functions such as:
• Edge OSPF for much greater extensi-
bility than RIP can provide
• Edge PIM sparse modes for routing of
multicast streams
• Policy-based routing
• sFlow
®
hardware sampling
Summit X250e switches provide non-blocking architecture with copper and fiber Fast Ethernet ports for demanding edge
applications. Combining exceptional QoS and advanced traffic management with resiliency, comprehensive security features
and non-blocking performance, Summit X250e switches are designed to be the cornerstone of an advanced intelligent
converged network.
