support from existing Gigabit Ethernetbased servers to 10 GbE-based highperformance servers to start the transition
to the new virtualized environment.
Data Sheet
Summit X670 Series
Product Overview
The Summit X670 series is available in two models: Summit X670V and
Summit X670. Summit X670V provides high-density for 10 Gigabit Ethernet
switching in a small 1RU form factor. The switch supports up to 64 ports
in one system and 448 ports in a stacked system using high-speed
SummitStack-V160, which provides 160 Gbps throughput and distributed
forwarding. The Summit X670 model provides up to 48 ports in one system
and up to 352 ports in a stacked system using SummitStack-V technology.
With its versatile design, the Summit X670 series provides high density
Layer 2/3 switching with low latency cut-through switching, and IPv4 and
IPv6 unicast and multicast routing to enable enterprise aggregation and
core backbone deployment in AC-powered and DC-powered environments.
Summit X670 series simplifies network operation with the ExtremeXOS
modular operating system (OS), which is used amongst all Extreme
Networks Summit and BlackDiamond Ethernet switches. The high
availability ExtremeXOS operating system provides simplicity and ease of
operation through the use of one OS everywhere in the network.
10 Gigabit Ethernet Switching
The Summit X670 model oers 48-port 10 Gigabit Ethernet non-blocking
switching with 10GBASE-X SFP+ interfaces. Summit X670 is capable of
Layer 2 and Layer 3 forwarding at up to 714 million packets per second
forwarding rate in a small 1RU form factor, enabling next-generation highperformance server deployment in data centers. Both models support
SummitStack-V high-speed, longer distance stacking.

SummitStack-V: Flexible Stacking
Over 10 Gigabit Ethernet
SummitStack-V capability utilizes 10 GbE ports as
stacking ports, enabling the use of standard cabling and
optics technologies used for 10 GbE such as XFP, SFP+,
10GBASE-T and XENPAK. SummitStack-V provides longdistance stacking connectivity of up to 40 km while
reducing the cable complexity of implementing a stacking
solution. SummitStack-V enabled 10 GbE ports must be
physically direct-connected.
40 Gigabit Ethernet Uplinks and High-Speed 160
Gbps Stacking
The Summit X670V model can support an additional four
QSFP+ ports of 40 GbE with the optional VIM4-40G4X
module. With this option, you can maximize the number
of interfaces for servers up to 48 ports while using the
dedicated four-port 40 GbE module for uplink connectivity.
The optional VIM4-40G4X provides 160 Gbps aggregated
bandwidth to the backbone. Each 40 Gigabit Ethernet port
can be independently configured as 40 Gigabit Ethernet
or 4 x 10 Gigabit Ethernet; thus with the VIM4-40G4X
module, Summit X670V can support up to 64 ports of 10
Gigabit Ethernet in a 1RU form factor and is capable of
Layer 2 and Layer 3 forwarding at up to 952 million packets
per second forwarding rate. This configuration provides
3:1 oversubscription from front ports (total 480 Gbps
bandwidth) to uplink ports (total 160 Gbps bandwidth) and
maximizes server port density.
Summit X670V together with VIM4-40G4X provides
high speed stacking running at 160 Gbps through the
SummitStack-V160 technology. SummitStack-V160 can
be enabled on two 40 Gigabit Ethernet QSFP+ ports on
the VIM4-40G4X, using half of the module’s four ports as
stacking interfaces. SummitStack-V160 is compatible with
SummitStack-V80, which is available for Summit X460 and
Summit X480 series switches.
Low Latency Switching for High-Frequency
Trading anD Cluster Computing
Summit X670 provides sub-microsecond latency and
supports cut-through switching to help optimize the high
frequency trading application as well as latency sensitive
cluster computing.
The power supplies are also highly ecient, which
minimizes the loss of power and unnecessary heat
generated by the power supply. Summit X670 series
switches can be used in AC or DC powered environments.
Supports Virtualized Data Centers
With the optional feature pack, Summit X670 switches
can also support Direct Attach (VEPA), which eliminates
the virtual switch layer, simplifying the network and
improving performance. Direct Attach enables data center
simplification by reducing network tiers from 4 or 5 tiers to
just 3 or 2 tiers, depending on the size of the data center.
To further enhance data center operations, Summit
X670 switches support XNV (ExtremeXOS Network
Virtualization), which is natively supported in the
ExtremeXOS operating system and is a licensable feature
pack for Ridgeline, a network and service management
application, sold separately. XNV provides insight, control
and automation for virtualized data centers.
Summit X670 switches also support Priority-based Flow
Control (PFC, or IEEE 802.1Qbb), which allows network
trac to be controlled independently based on Class of
Service. PFC allows network trac that requires lossless
throughput to be prioritized, while other trac types that
do not require or perform better without PFC can continue
as normal.
Software Defined Networking (SDN)
ExtremeXOS implementations of OpenFlow APIs allow
an external OpenFlow-based SDN controller to access
and control the forwarding plane of ExtremeXOS network
devices. ExtremeXOS-based switches oer a programming
interface through OpenFlow to enable high degree of
automation in provisioning network services for many upper
layer business critical applications running the OpenFlowbased SDN controller.
Extreme XOS-based switches also allow for integration with
the OpenStack open source cloud computing platform for
public and private clouds through the Extreme Networks
Quantum plugin. The plugin provides a scalable, automated,
rich API-driven system that enables networking-as-aservice model managing data center interconnect solutions
and large multi-tenant networks.
Green Design
The Summit X670 series is designed to be environmentally
green. System power consumption is very low at both
high-load and idle situations through the power-ecient
hardware design.

Audio Video Bridging (AVB)
ExtremeXOS supports IEEE Audio Video Bridging (AVB)
standards to enable reliable real-time audio and video
transmissions over Ethernet, for high-definition and timesensitive multimedia streams with assigned Quality of
2
Page 3
Service (QoS). ExtremeXOS leverages AVB to identify
and reserve network resources for A/V trac streams and
supports synchronous streaming capabilities to ensure
reliable and high-quality A/V transmissions over Ethernet.
AVB also enables time sensitive multimedia streams to
be sent over the Ethernet network with low latency and
provides service quality for high definition information and
entertainment applications.
DCB Support with Enterprise Core Class Scalability
The Summit X670 series supports Data Center Bridging
features such as Priority Flow Control (PFC), Enhanced
Transmission Selection (ETS) and Data Center Bridging
eXchange (DCBX) for data center convergence. At the same
time, the Summit X670 series oers more cost-eective
10 Gigabit Ethernet switches, for both small-sized core
backbone and traditional three-tier network architectures.
Summit X670 series can support 10 Gigabit Ethernet campus
aggregation with its core class routing and switching
scalability. The Summit X670 series can support up to 16,000
IPv6 longest prefix matching routing tables, 6,000 IP ARP
entries and 3,000 IP multicast group entries.
One Operating System
Extreme Networks simplifies network operation by
oering one common OS – ExtremeXOS – throughout the
BlackDiamond and Summit switchIng portfolio. From 10/100
Mbps switching products such as Summit X150 and Summit
X250e to the multi-10 gigabit core backbone BlackDiamond
modular chassis switches, all switches can run the same
version of the OS, which helps deploy, operate and maintain
your entire network and reduce operating costs.
10 Gigabit Ethernet SFP+
The Summit X670 series supports SFP+ optics, which can
support passive copper cable for up to 10 meters for Summit
X670V and up to 3 meters for Summit X670. The switches
also support fiber-optical cable installation with SFP+
transceivers. Summit X670 SFP+ ports support dual interface
speeds of Gigabit Ethernet and 10 GbE. SFP+ ports can
accept both gigabit SFP and 10 gigabit SFP, and depending
upon the pluggable optics you choose, SFP+ ports can work
in both modes.
40 Gigabit Ethernet QSFP+
The Summit X670V model provides a VIM4 slot for the optional
VIM4-40G4X module. The VIM4-40G4X module supports
four QSFP+ optics, and supports up to four ports of 40 GbE.
40 GbE QSFP+ ports can accept QSFP+ passive and active
cables, as well as QSFP+ transceivers. Each 40 GbE port can be
configured as a 40 GbE port or as four 10 GbE ports.

Low Power Consumption with Optimized
Cooling Options
The Summit X670 series consumes very low power and
provides optimized cooling options. Most servers installed in
a standard 19-inch rack system flow air from front to back to
maximize cooling performance. Compared to side-to-side air
flow, front-to-back air flow provides more eective cooling
throughout the rack system in the data center. The Summit
X670 series has 2+1 hot swappable fan tray oering eective
front-to-back air flow, or back-to-front air flow. Back-to-front
air flow allows placement of 10 Gigabit Ethernet SFP+ ports
in the back side of the rack and reduces distance between
switches and servers for 10GBASE-CR SFP+ passive copper
cable installations.
Modular Operating System for
Non-Stop Operation
Preemptive Multitasking and Protected Memory
Summit X670 series switches allow each of many
applications—such as Open Shortest Path First (OSPF)
and Spanning Tree Protocol (STP)—to run as separate OS
processes that are protected from each other. This drives
increased system integrity and inherently protects against
DoS attacks.
Loadable Software Modules
The modular design of the ExtremeXOS OS allows the
upgrading of individual software modules, should this be
necessary, leading to higher availability in the network.
High Availability Network
Protocols
Ethernet Automatic Protection Switching (EAPS)
EAPS allows the IP network to provide the level of resiliency
and uptime that users expect from their traditional voice
network. EAPS is more adaptable than Spanning Tree or
Rapid Spanning Tree protocols and oers sub-second (less
than 50 milliseconds) recovery that delivers consistent
failover regardless of the number of VLANs, network nodes
or network topology. Since EAPS allows the network to
recover almost transparently, Voice-over-IP (VoIP) calls will
not drop and digital video feeds will not freeze or pixelize in
most situations.
Spanning Tree/Rapid Spanning Tree Protocols
Summit X670 supports Spanning Tree (802.1D), Per VLAN
Spanning Tree (PVST+), Rapid Spanning Tree (802.1w) and
Multiple Instances of Spanning Tree (802.1s) protocols for
Layer 2 resiliency.
Process Monitoring and Restart
ExtremeXOS increases network availability using process
monitoring and restart. Each independent OS process is
monitored in real time. If a process becomes unresponsive or
stops running, it can be automatically restarted.
Software-enhanced availability allows users to remain
connected to the network even if part of the network
infrastructure is down. Summit X670 continuously checks
for problems in the uplink connections using advanced
Layer 3 protocols such as OSPF, VRRP and Extreme Standby
Router Protocol (ESRP, supported in Layer 2 or Layer 3), and
dynamically routes trac around the problem.

Equal Cost Multipath
IP Security
Equal Cost Multipath (ECMP) routing allows uplinks to be
load balanced for performance and cost savings while
also supporting redundant failover. If an uplink fails, trac
is automatically routed to the remaining uplinks and
connectivity is maintained.
Link Aggregation (802.3ad)
Link aggregation allows trunking of up to 32 links on a single
switch and up to 64 links in a SummitStack.
Multi-Switch LAG (M-LAG)
M-LAG can address bandwidth limitations and improve
network resiliency, in part by routing network trac around
bottlenecks, reducing the risks of a single point of failure,
and allowing load balancing across multiple switches.
Hardware Redundancy
Summit X670 series switches support a dual redundant AC/
DC power supply to provide high availability. The power
supply can be hot-swapped and replaced should it fail.
Summit X670 also supports N+1 redundant hot-swappable
fan trays.
Robust IP / MAC Security
Framework
Media Access Control (MAC) Lockdown
MAC security allows the lockdown of a port to a given MAC
address and limiting the number of MAC addresses on a
port. This capability can be used to dedicate ports to specific
hosts or devices such as VoIP phones or printers and avoid
abuse of the port—a capability that can be especially useful
in environments such as hotels. In addition, an aging timer
can be configured for the MAC lockdown, protecting the
network from the eects of attacks using (often rapidly)
changing MAC addresses.
ExtremeXOS IP security framework helps protect the
network infrastructure, network services such as DHCP and
DNS and host computers from spoofing and man-in-the-
middle attacks. It also protects the network from statically
configured and/or spoofed IP addresses and builds an
external trusted database of MAC/IP/port bindings providing
the trac’s source from a specific address for immediate
defense.
Identity Management
Identity Manager allows network managers to track users
who access their network. User identity is captured based
on NetLogin authentication, LLDP discovery and Kerberos
snooping. ExtremeXOS uses the information to then report
on the MAC, VLAN, computer hostname, and port location of
the user. Further, Identity Manager can create both roles and
policies, and then bind them together to create role-based
profiles based on organizational structure or other logical
groupings, and apply them across multiple users to allow
appropriate access to network resources. In addition, support
for Wide Key ACLs further improves security by going
beyond the typical source/destination and MAC address as
identification criteria access mechanism to provide filtering
capabilities.
threat detection and mitigation, and mirrors trac to
security appliances for further analysis of suspicious trac in
the network.
sFlow
Summit X670 series supports hardware-based sFlow®
sampling that provides the ability to sample application-level
trac flows on all interfaces simultaneously.

Port Mirroring
To allow threat detection and prevention, Summit X670
supports many-to-one and one-to-many port mirroring.
This allows the mirroring of trac to an external network
appliance such as an intrusion detection device for trend
analysis or for utilization by a network administrator for
diagnostic purposes. Port mirroring can also be enabled
across switches in a stack.
Line-Rate Ingress and Egress ACLs
ACLs are one of the most powerful components used
in controlling network resource utilization as well as in
protecting the network. Summit X670 series supports up
to 2,048 ingress ACLs and 1,024 egress ACLs per system
based on Layer 2-, 3- or 4-header information such as the
MAC or IP source/destination address. ACLs are used for
filtering the trac, as well as classifying the trac flow to
control bandwidth, priority, mirroring, and policy-based
routing/switching.
Secure and Comprehensive Network Management
As the network becomes a foundation of the enterprise
application, network management becomes an important
piece of the solution. Summit X670 supports comprehensive
network management through Command Line Interface
(CLI), SNMP v1, v2c, v3, and ExtremeXOS ScreenPlay
embedded XML-based Web user interface. With a variety of
management options and consistency across other Extreme
Networks modular and stackable switches, Summit X670
series switches provide ease of management for demanding
converged applications.
Extreme Networks has developed tools that simplify and
help in eciently managing your network. Ridgeline network
and service management provides fault, configuration,
accounting, performance and security functions, allowing
more eective management of Extreme Networks products,
solutions and third-party devices in a converged network.
Denial of Service Protection
Summit X670 series eectively handles Denial of Service
(DoS) attacks. If the switch detects an unusually large
number of packets in the CPU input queue, it assembles
ACLs that automatically stop these packets from reaching
the CPU. After a period of time these ACLs are removed, and
reinstalled if the attack continues. ASIC-based LPM routing
eliminates the need for control plane software to learn new
flows, allowing more network resilience against DoS attacks.
