The unsurpassed software features, capacity, and performance
of the Summit48si enable customers to provide more Layer 3
services to more users while using less space and at a lower
Total Cost of Ownership than ever before.
Summit48si from Extreme Networks® sets the
standard for Layer 3 switching at the edge by
maximizing 10/100 port density and architecting
high levels of reliability while maintaining leadership
in Layer 3 software features and performance. The
unsurpassed software features, capacity and
performance of the Summit48si enable customers to
provide more Layer 3 services to more users while
using less space and at a lower Total Cost of
Ownership than ever before.
At one rack unit (1RU) in height, the Summit48si
packs 48 10/100 Ethernet ports and 2 Gigabit
Ethernet ports with nonblocking capacity to support
every port at full line-rate. This compact yet
powerful package is capable of supporting two hot
swappable load sharing power supplies—a reliability
first in a 1RU Layer 3 switch. The Summit48si
reliability is enhanced even further with dual Gigabit
Ethernet uplinks, both of which are active and can
be aggregated for enhanced throughput and
increased redundancy.
Extreme Networks’ advanced Layer 3 software
feature set, combined with dual hot-swappable
power supplies makes the Summit48si an unbeatable
solution at the edge of the network.
Target Applications
• In enterprise markets—such as banking,
manufacturing, education—where highperformance, reliability and security features
are critical
• Metro Ethernet access rings where granular
bandwidth allocation, billing, and security are
• Metro service providers that need high speed
IP unicast and multicast services supporting
carrier-class routing protocols like OSPF,

Summit48si Customer Benefits Quality of Service and
Application Flexibility
Maximum Performance
With industry-leading performance for
the most demanding applications,
Summit48si has a non-blocking architecture with 17.5 gigabits of throughput
with wire-speed performance on every
Bidirectional rate shaping allows you to
manage bandwidth on Layer 2 and Layer 3
traffic flowing both to and from the switch.
DiffServ and 802.1p deliver varied levels
of service for time-sensitive, demanding
applications for voice, video and data
and ensure efficient bandwidth usage.
Eight hardware queues provide granularity for multiple applications, and
guarantee low latency/low jitter for time
sensitive applications (voice and
multimedia) with support for advanced
scheduling algorithms.
Application Flexibility
The Summit48si features a 128K routing
table size for maximum forwarding
control at the edge with the same
advanced feature set supported end-toend throughout the customer’s network.
Protocol-based VLANs enable the
network administrators to define a
packet filter that the switch uses as the matching criteria to determine if a
particular packet belongs to a particular VLAN.
Virtual MANs (vMANs) feature is useful
in building transparent private networks
that need point-to-point or point-tomultipoint connectivity across an
Ethernet infrastructure.
Policy-Based QoS with 8 queues per
port, bidirectional rate shaping and
bandwidth management provides the
ability to prioritize mission-critical
applications and traffic to deliver
maximum productivity and deliver
delay-sensitive applications such as
voice and video.
High Network Availability
Redundant hot-swappable power
supplies, and fiber gigabit uplinks
provide true high availability as

failover to the redundant port and the
user’s application is unaffected. The user
stays connected to the network and
remains productive.
The Summit48si delivers connectivity and
productivity with advanced high availability features, such as EAPS (RFC 3619)
with multidomain support to deliver subsecond (less than 50ms recovery)
protection switching to interconnected
switches in an Ethernet ring topology.
EAPS is similar to the Spanning Tree
Protocol (STP), but 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.
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
Equal Cost Multipath (ECMP) allows the
networks to be even more resilient 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 link and become active. Thus
multihomed redundancy can be easily
designed without the complexity of
a protocol.
Comprehensive Security for
Control at the Edge of the
With IEEE 802.1x Login, network managers can always control who is connected to
the network and prevent unauthorized
clients from gaining access to the network.
Web-based Network Login does not
require any specific client software and
can work with any HTTP-compliant web
browser and thus is independent of
platform. Every user on every port can be
authenticated so the network is protected
at the most sensitive point of attack.
MAC address security allows identifying
port abuse such as rogue wireless access
points or hubs/switches on edge ports. It
includes two features: lockdown on a per
port basis and limiting the number of MAC
addresses learned by a port. Lockdown
and saving learned MAC addresses
between reboot can be used to protect
dedicated ports for VoIP phones or
printers from abuse. Limiting the number
of MAC addresses learned on a port also
allows enforcement of service level
agreements in tenant or service provider
SSHv2 allows network managers to
securely configure the box remotely
without any risk of packet snooping or
man-in-the-middle attack. SSHv2, DoS
protection, TACACS+ and RADIUS bring
reliable secure configuration traffic
(encryption) and authentication.
Scanning of malicious users or virusinfected end-clients can cause the
Forwarding Database (FDB) table to fill
up very quickly and FDB replacements
to happen at higher rate. The attacks
can hurt the quality of internal traffic
significantly, if all Layer 3 forwarding is
made by host lookup. The IPDA SUBNET
lookup feature forces the attack traffic to
use the IPFDB SUBNET forwarding table
instead of the host-forwarding table.
This feature is intended to decrease
frequency of FDB collision and replacement and accelerate packet forwarding
for Summit48si.
Multiple Supplicant (client) enables
multiple clients to be individually authenticated on the same port.
The Summit48si has wire-speed Layers 2 – 4 ACLs on every port for
maximum security while maintaining
maximum throughput.
Ease of Management
Extreme Networks has developed tools
that save you time and resources in
managing your network. EPICenter®
provides all fault configuration, accounting, performance, and security functions
to manage Extreme Networks’ multi-layer
switching equipment in a converged
network. EPICenter Policy Manager
provides layer-independent policy
enforcement for Layers 1 – 4.
Extreme Networks’ software application,
ServiceWatch®, delivers powerful, Layers 4 – 7 monitoring and management
for mission-critical network services.
