Data Sheet
ExtremeSwitching™ X460-G2 Series
Scalable advanced aggregation switch with ExtremeXOS®
modular operating system.
The X460-G2 series is based on Extreme Networks revolutionary
ExtremeXOS, a highly resilient OS that provides continuous uptime,
manageability and operational eciency. Each switch oers the same highperformance, non-blocking hardware technology, in the Extreme Networks
tradition of simplifying network deployments through the use of common
hardware and software throughout the network.
The X460-G2 switches are eective campus edge switches that support
Energy Ecient Ethernet (EEE – IEEE 802.3az) with IEEE 802.3at PoEplus and can also serve as aggregation switches for traditional enterprise
networks. The X460-G2 series is also an option for DSLAM or CMTS
aggregation, or for active Ethernet access.
The X460-G2 can also be used as a top-of-rack switch for many data
center environments with features such as high-density Gigabit Ethernet
for concentrated data center environments; XNV™ (ExtremeXOS Network
Virtualization) for centralized network-based Virtual Machine (VM)
inventory, VM location history and VM provisioning; Direct Attach™ to
ooad VM switching from servers, thereby improving performance; highcapacity Layer 2/Layer 3 scalability for highly virtualized data centers; and
intra-rack and cross-rack stacking with industry leading flexibility.
Comprehensive Security Management
• User policy and host integrity enforcement, and identity management
• Universal Port Dynamic Security Profiles to provide fine granular
security policies in the network

• Threat detection and response instrumentation to
react to network intrusion with CLEAR-Flow Security
Rules Engine
• Denial of Service (DoS) protection and IP security
against man-in-the-middle and DoS attacks to harden
the network infrastructure
• Role Based Policy enables support for policy profiles to
secure and provision network resources based upon the
role the user or device plays within the network
Flexible Port Configuration
The X460-G2 oers flexible port configurations. X460-G2
24 port copper models with 10G uplinks can have up to
8 fiber GbE ports (four dedicated ports + four shared
ports) and 20 GbE copper ports (PoE-plus or non-PoE).
The X460-G2 24 port copper models with 1Gb uplinks can
provide up to 12 SFP ports with 20 Gigabit Ethernet ports
or eight SFP ports with 24 copper GbE ports.
All models come equipped with either 4 ports of SFP+
10 GbE or 4 ports of SFP 1GbE resident on the faceplate
of each model. Through an optional VIM slot, X460-G2
switches can be equipped with an additional 2 ports of 10
GbE for a total of six 10 Gigabit Ethernet ports on the 10Gb
uplink models.
As another option, each unit can be equipped with 2 ports
of QSFP+ 40 Gigabit Ethernet for uplinks or stacking.
provides long-distance 40 Gbps stacking connectivity
of up to 40 km while reducing the cable complexity of
implementing a stacking solution. SummitStack-V is
compatible with X440, X440-G2, X450, X450-G2, X460,
X460-G2, X480, X670, X670V, X670-G2 and X770 switches
running the same version of ExtremeXOS. SummitStack-V
enabled 10 GbE ports must be physically direct-connected.
Note: SummitStack-V is NOT supported on the 1GbE (SFP) front panel
faceplate ports of non-10Gb X460-G2 models but SummitStack-V is
supported on the 10GbE VIM cards (VIM-2x or VIM-2t) when used in the
non-10GbE switches.
SummitStack-V160 — Flexible Stacking
Over 40GbE
The X460-G2 also supports high-speed 160 Gbps stacking,
which is ideal for demanding applications where a high
volume of trac traverses through the stacking links, yet
bandwidth is not compromised through stacking.
SummitStack-V160 can support passive copper cable
(up to 3m), active multi-mode fiber cable (up to 100m),
and QSFP+ optical transceivers for 40 GbE up to 10km.
With SummitStack-V160, the X460-G2 provides a flexible
stacking solution inside the data center or central oce
to create a virtualized switching infrastructure across rows
of racks. SummitStack-V160 is compatible with X460-G2,
X480, X670V, X670-G2 and X770 switches running the
same version of ExtremeXOS.
Note: The 40Gb Ethernet ports CANNOT be fanned out into four
10Gb ports.
High-Performance Stacking
Up to eight X460-G2 switches can be stacked using
three dierent methods of stacking: SummitStack,
SummitStack-V, and SummitStack-V160.
SummitStack — Stacking Using Copper
CX4 Connections
The X460-G2 supports SummitStack by using the X460-G2VIM-2ss module, which oers high-speed 40 Gbps stacking
performance and provides compatibility with the X440,
X460, X460-G2 and X480 stackable switches running the
same version of ExtremeXOS.
SummitStack-V — Flexible Stacking Over 10GbE
ExtremeXOS supports the SummitStack-V capability
using 2 of the native 10 GbE ports on the faceplate as
stacking ports, enabling the use of standard cabling and
optics technologies used for 10 GbE SFP+, SummitStack-V
Intelligent Switching and MPLS/
H-VPLS Support
The X460-G2 supports sophisticated and intelligent
Layer 2 switching, as well as Layer 3 IPv4/IPv6 routing
including policy-based switching/routing, Provider Bridges,
bidirectional ingress and egress Access Control Lists, and
bandwidth control by 8 Kbps granularity both for ingress
and egress.
To provide scalable network architectures used mainly
for Carrier Ethernet network deployment, the X460-G2
supports MPLS LSP-based Layer 3 forwarding and
Hierarchical VPLS (H-VPLS) for transparent LAN
services. With H-VPLS, transparent Layer 3 networks
can be extended throughout the Layer 3 network cloud by
using a VPLS tunnel between the regional transparent
LAN services typically built by Provider Bridges (IEEE
802.1ad) technology.

IEEE 802.3at PoE-plus
Role-based Policy
IEEE 802.3af Power over Ethernet has been widely used
in the campus enterprise edge network for Ethernetpowered devices such as wireless access points, Voice
over IP phones, and security cameras. Ethernet port
extenders such as Extreme Networks ReachNXT™ 100-8t
can also utilize PoE, making installation and management
easier and reducing maintenance costs. The newer IEEE
802.3at PoEplus standard expands upon Power over
Ethernet by increasing the power limit up to 30 watts, and
by standardizing power negotiation by using LLDP. The
X460-G2 supports IEEE 802.3at PoE-plus and supports
standards-compliant PoE devices today and into the future.
1588 Precision Time Protocol (PTP)
The X460-G2 oers Boundary Clock (BC), Transparent
Clock (TC), and Ordinary Clock (OC) for synchronizing
phase and frequency and allowing the network and
the connected devices to be synchronized down to
microseconds of accuracy over Ethernet connection.
Audio Video Bridging (AVB)
The X460-G2 series supports IEEE 802.1 Audio Video
Bridging to enable reliable, real-time audio/video
transmission over Ethernet. AVB technology delivers the
quality of service required for today’s high-definition and
time-sensitive multimedia streams.
Utilizing NetSight Policy Management, the role-based policy
framework empowers a network administrator to define
distinct roles or profiles that represent industry specific
operational groups that may exist in an education or a
business environment (e.g., administrator, teacher, student,
guest). Each defined role is granted individualized access to
specific network services and applications and these access
privileges remain associated with users as they move across
both wired and wireless network access points.
Users can be authenticated via IEEE 802.1X, MAC address,
or web authentication, and then assigned a pre-defined
operational role. Network operations can be seamlessly
tailored to meet business-oriented requirements by
providing each role with individualized access to network
services and applications, thus aligning network resource
utilization with business goals and priorities.
In addition, administrators can easily transition from basic
VLAN and complex ACL deployments to the Extreme
Networks role based policy framework in a seamless
fashion, without the need to make changes to their
RADIUS infrastructure.
Ordering Notes
The X460-G2 base switches do not ship with fan trays
or power supplies. The fan tray, power supplies, and any
optional VIM cards must be ordered separately. There is
only one optional VIM slot on each X460-G2 switch. The
optional Timing Module has a separate dedicated slot on
the back of the X460-G2 switch. Beginning with EXOS 22.1,
all X460-G2 base systems will include an Advanced Edge
license -- an upgrade over the Edge License bundled with
earlier EXOS releases.
