BOUT THE SUMMIT FAMILY OF SWITCHES
A
Network managers are currently faced with the challenge of creating networks that can
provide ultra-fast speed and high performance to serve the needs of today’s network
users, while simultaneously preserving the investment they have made in Ethernet and
Fast Ethernet tech nology.
By addressing the entire spectrum of Ethernet data rates (10/100/1000 Mbps), the
Summit family of LAN switches enables you to introduce high-speed Gigabit Ethernet
backbones into your exist ing network, w hile maintaining established connecti ons to the
10 Mbps and 100 Mbps segments that already exist.

The major difference between the models of the Summit switch is the port
configurations on each switch model. Summit switches use a combination of the
following types of ports:
• Fixed 1000BASE-SX ports using 850nm duplex SC connectors
• Modular 1000BASE-LX and 1000BASE-LX10 using Gigabit Interface Connectors
(GBICs)
• 10BASE-T/100BASE-TX ports using standard RJ-45 connectors
• 100BASE-FX ports using st andard SC connectors
Table 1-1 describes port configurations available on the different Summit switch models.

UMMARY OF FEATURES
S
ULL-DUPLEX
F
The Summit switch provides full-duplex support for all ports. Fu ll-duplex allows
frames to be transmitted and received simultaneously and, in effect, doubles the
bandwidth av ailable on a l ink. All 10 /100 Mbps p orts on the S ummit auton egotiate fo r
half- or full-duplex operation.
ORT REDUNDANCY
P
The Summit2, Summit3, and Summit48 have an optional redundant Gigabit Ethernet
port. Using the redundant port, you can dual-home these models to one or two
switches. Figure 1-1 illustrates a Summit2 dual-homed to two different switches.
Dual-homed
Active
Figure 1-1:
Backup
Dual-homing confi guration
In the event that the active port fails or loses link status, the redundant port is
automatically activated. When the primary port resumes operation, the redundant port
becomes inactive. This feature can be disabled.
The redundant port cannot be used for load sharing when the primary port is active. If
the primary port becomes inactive, the redundant port is activated in the load sharing
configuration.
UMMIT SWITCH INSTALLATION AND USER GUIDE

UMMIT OVERVIEW
S
OAD SHARING
L
Load sharing with Summi t switches allows the user to increase bandwidth and
resilience between switches by using a group of ports to carry traffic in parallel between
switches. The sharing algorithm a llows the switch to use mu ltiple ports as a single
logical port. For example, VLANs see the load-sharing group as a single virtual port.
The algorithm also guarantees packet sequencing between clients.
For information on load shar ing, refer to Chapter 4.
IRTUAL
V
LANS (VLANS)
The Summit has a VLAN feature that enables you to const ruct your broadcast domains
without being restricted by physical conn ections. Up to 255 VLANs can be defined on
the Summit. A VLAN is a group of location- and topology-independent devices that
communicate as if they were on the same physica l local area network (LAN).
Implementing VLAN s on your networ k has the followin g three advantages :
• It helps to control broadcast traffic. If a device in VLAN marketing transmits a
broadcast frame, only VLAN marketing devices receive the frame.
• It provides extra security. Devices in VLAN marketing can only communicate with
devices on VLAN sales using a device that provides routing services.
• It eases the change and movement of devices on networks. If a device in VLAN
marketing is moved to a port in another part of the network, all you must do is
specify that the new port belongs to VLA N marketing.
For more infor mation on VLANs, refer to Chapter 5.
PANNING TREE PROTOCOL
S
(STP)
The Summit supports the IEEE 802.1D Spanning Tree Protocol (STP), which is a
bridge-based mechanism for providing fault tolerance on ne tworks. STP enables you to
implement parallel paths for ne twork traffic, and ensure the following:
• Redundant paths are disabled when the main paths are operational.
• Redundant paths are enabled if the main traffic paths fail.
1-6 S
UMMIT SWITCH INSTALLATION AND USER GUIDE
UMMARY OF FEATURES
S
The Summit supports up to 64 Spann ing Tree Domains ( STPDs).
For more information on STP, refer to Chapter 7.
UALITY OF SERVICE
Q
(QOS)
The Summit has policy-based Qual ity of Service (QoS) features that enable you to
specify service levels for different traffic groups. By default, all traffic is assigned with
the “normal” QoS policy profile. If needed, you can create other QoS policies and apply
them to different traffic types so that they have different guaranteed minimum
bandwidth, maximum bandwidth, and priority.
For more information on Qualit y of Serv ice, refer to Chapter 8.
NICAST ROUTING
IP U
The Summit can route IP traffic between the VLANs that are configured as virtual
router interfaces. Both dynamic and static IP routes are maintained in the routing table.
The following routing protocols are supported:
• RIP version 1
• RIP version 2
• OSPF
For more information on IP uni cast routing, refer to Cha pter 9.
ULTICAST ROUTING
IP M
The Summit can use IP multicastin g to allow a single IP hos t to transmit a packet to a
group of IP hosts. The Summit supports statically configured IP multicast routes, and
multicast routes that are learned by way of the D istance Vector Multica st Routing
Protocol (DVMRP).
For more information on IP multicast rou ting, refer to Chapter 11.

As shown in Figure 1-2 , the family of Summit switches offer a unique end-to-end LAN
system solution. From the desktop, to the gigabit core, to the data center/server farm,
there are Summit switches with an optimized hardware configuration to match the
requirements. ExtremeWare software is common to all Summit switches, and allows for
the same services to operate across the entire product family. All Summit switches
deliver wire-speed throughput and end-to-end policy based Quality of Service.

In the gigabit core of the network, the Sum mit1 and Summit2 act as a ggregators of
Gigabit Ethernet links from the edge and data center switches, as well as Ethernet and
Fast Ethernet links from legacy routers and hubs. In the core of the network, the
Summit1 and Summit2 ca n scale in port density and performa nce by connecting to a
Summit Virtual Chassis to support up to 32 non- blocking Gigabit Ethernet po rts at 48
million packets per second (pps), or 128 non-blocking 10/100BASE-TX ports at 19
million pps.
In the data center or server farm, the Summit4 offers the right mix of ports and features
for servers. Data centers and server farms require integrated wire-speed routing to
eliminate the performance penalty associated with legacy routers when servers had to
be separated into different subnets. In addition, the Summit4 supports trunking of
either Ethernet, Fast Ethernet, or Gigabit Ethernet ports to match the performance of the
LAN connection to the performance of the server. The goal is to only buy the amount of
bandwidth that is needed and can be used. This is ideal for servers that can drive 400
Mbps on trunk Fast Ethernet ports, but would not be capable of more than 400 Mbps
performance on a Gigabit Ethernet port. The port density and performance of the
Summit4 can be scaled with the Summit Virtual Chassis to 16 Gigabit Ethernet ports,
and 128 10/100BASE-T X ports at 43 million pps.
At the edge of the network, higher-performance desktops need dedicated throughput,
while other devices can use small, shared segments. For higher-performance
connections, use the Summit3 and Summit48 switches (which offer 24 10/100BASE-TX
ports) and a single Gigabit Ethernet port, or 48 10/100BASE-TX ports and two Gigabit
Ethernet ports, respectively. For shared desktop segments, the Summit2 offers 16
10/100BASE-TX ports and two Gigabit Ethernet ports. Combining the Summit3 and the
Summit48 with the Summi t Virtual Chassis, desktop switching port densities can scale
to 192 10/100BASE-TX ports at 28 million pps, and 384 10 /100BASE-TX ports at 28
million pp s, respe ctively.

The Summit1 has eight Gigabit Ethernet ports. Six of the ports use SC connectors and
support 1000BASE-SX over multimode fiber-optic cable. Ports 1 and 8 use modular
GBIC connectors.
