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 offer 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 automated
provisioning of VoIP using Link Layer
Discovery Protocol (LLDP) and 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 15.4 and QoS and
resiliency to match the failover require-
ments for latency-sensitive services like
VoIP phones. With Summit X250e,
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-port by adding
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-po-
licing 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—
allowing network managers to build networks
with low end-to-end latency and jitter.
Comprehensive Network
Management
As network becomes a foundation of the
enterprise application, the network
management becomes important piece of
solution. Summit X250e supports compre-
hensive network management through
Command Line Interface (CLI), SNMP v1,
v2c, v3 and 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
®
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 proto-
cols 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.
