Figure 1: Port Configuration Options for Summit X480 Switches
Flexible Port Configuration
Summit X480 offers flexible port
configurations from standard
configuration to optional VIM2 modules.
For Summit X480-24x, half of the
Gigabit Ethernet ports can handle dual
personality—select from either
10/100/1000BASE-T copper Gigabit
Ethernet or 100/1000BASE-X fiber
Gigabit Ethernet connectivity. In the case
of Summit X480-48t, the last four Gigabit Ethernet ports are configured as dual
personality ports to provide flexibility
between copper and fiber Gigabit
Ethernet.
Through the VIM2 slot, Summit X480 can
add an additional four 10 Gigabit Ethernet
or SummitStack stacking ports. For
stacking, depending upon the needs for
bandwidth across the units in a stack,
Summit X480 supports 40 Gbps
SummitStack or 128Gbps SummitStack128
through VIM2 option modules (See Figure
2: Summit X480-24x flexible port configuration).
A third, option, SummitStack-V,
utilizes 10 GbE ports as stacking ports.
|
Figure 2: Summit X480-24x Flexible Port Configuration
|
Summit X480 supports flexible 10 gigabit
optical transceivers such as 10GBASE-SR,
LR, ER and ZR as well as tunable DWDM.
Tunable DWDM (Dense Wavelength
Division Multiplexing) support allows
service providers and others to tune XFP
10 Gigabit Ethernet optics to a specific
frequency, reducing the need for additional
fiber runs and XFP sparing. Digital
Diagnostics Monitoring Interface support
allows service providers to monitor and
diagnose pluggable optics in real-time.
High-Performance Stacking
Summit X480 supports SummitStack,
which provides 40 Gbps
(VIM2-SummitStack) or 128 Gbps
(VIM2-SummitStack128) of stacking
bandwidth. High-speed 128 Gbps stacking
is ideal for demanding applications where
a high volume of traffic traverses through
the stacking links, yet bandwidth is not
compromised through stacking. Highspeed
stacking is very useful in applications
such as top of rack when stacked
with Summit X480 and Summit X650
(requires optional conversion cable) and
gigabit aggregation in large enterprise or
data center networks. With the longer
stacking cables such as 5-meters, stacking
can be configured through different racks
horizontally in a row (see Figure 3) as
opposed to typical stacking system
installed vertically in a rack.
|
Figure 3: SummitStack Across Racks in a Row
|
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 long-distance 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.
SummitStack-V is compatible with Summit
X450e, X450a, X460, X480 and X650
switches running the same version of
ExtremeXOS (version 12.5 or greater).
High Scalability in 1RU Compact Switch
Summit X480 supports highly scalable Layer 2 or Layer 3 networks, as well as highly secure networks. Summit X480 has expansion
memory called TCAM built inside which can be partitioned by application types or by deployment scenarios. For larger Layer 2
network deployments, Summit X480 can support up to 512K MAC addresses. Similarly for larger Layer 3 routing environments,
Summit X480 can support core routing class scalability for up to 512K IPv4 routing LPM entries in hardware (See Figure 4: Summit
X480 scalability).

Figure 4: Summit X480 Scalability
Supports Virtualized Data Centers
Summit X480 switches also support Direct Attach™, 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 X480 switches support XNV™ (ExtremeXOS Network Virtualization), a set
of licensable software modules for both the ExtremeXOS based switching product portfolio, as well as for EPICenter®, a network provisioning
and management application. XNV brings insight, control and automation for highly virtualized data centers to the network.
Intelligent Switching and MPLS/H-VPLS Support
Summit X480 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, Summit X480 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 (see Figure 5: Summit X480 in a Carrier Ethernet application).

Figure 5: Summit X480 in a Carrier Ethernet Application
|
High Availability
Powered by the ExtremeXOS OS, Summit X480 supports process recovery and application upgrades without the need for a
system reboot. Summit X480 provides the high network availability required for mission-critical servers and applications through
its advanced modular OS, highly available hardware architecture and carrier-grade network redundancy protocols.
Modular Operating System for Continuous Operation
-
Preemptive Multitasking and Protected Memory
Summit X480 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.
-
-
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.
-
Loadable Software Modules
The modular design of ExtremeXOS OS
allows the upgrading of individual software
modules, should this be necessary, leading
to higher availability in the network (See
Figure 7: ExtremeXOS modular design).
|
Figure 7: ExtremeXOS Modular Design
|
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 offers 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 X480 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.
-
Software-Enhanced Availability
Software-enhanced availability allows users
to remain connected to the network even if
part of the network infrastructure is down.
Summit X480 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 traffic
around the problem.
-
Equal Cost Multipath
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, traffic is
automatically routed to the remaining
uplinks and connectivity is maintained.
-
Link Aggregation (802.3ad)
Link aggregation (LAG) allows trunking of
up to eight links on a single logical connection.
A maximum of 128 link aggregation
groups can be created.
-
Multi-Switch LAG (Ì-LAG)
M-LAG can address bandwidth limitations
and improve network resiliency, in part by
routing network traffic around bottlenecks,
reducing the risks of a single point of failure,
and allowing load balancing across multiple
switches.
Voice-Grade Stacking with SummitStack
Summit X480 provides high-speed 40 Gbps
stacking bandwidth and 128 Gbps stacking
through optional VIM2 modules. All
SummitStack stacking architecture is
designed to support mission-critical
applications by its highly available, rapid
failover capability with n-1 master redundancy,
distributed Layer 2 and Layer 3
switching, link aggregation across the stack,
and distributed uplinks. SummitStack
supports up to eight units in a stack,
including any mix of Summit X480, X650,
X450a, X450e and X250e running the same
version of ExtremeXOS and provides 50
milliseconds failover for path failure and
hitless master/backup failover along with
hitless protocol support such as OSPF
graceful restart and Network Login user
authentication. Summit X480 provides
chassis-like management and availability
with its SummitStack stacking technology
(See Figure 8: SummitStack stacking
architecture).
|
Figure 8: SummitStack Stacking Architecture
|
Hardware Redundancy
Summit X480 supports a dual redundant AC/
DC power supply to provide high availability.
The power supply can be hot-swapped and
replaced should it fail. Summit X480 supports
a hot-swappable, field replaceable fan.
|
Figure 9: Summit X480 High Availability Design

Comprehensive Security Management
Implementing a secure network means providing protection at the network perimeter as well as the core. Working together with
Extreme Networks Sentriant® family of products, Summit X480 uses advanced security functions in protecting your network
from known or potential threats.
Robust IP and MAC Security Framework
-
NetLogin
Network Login provides three types of
authentication—Web-based, MAC-based,
and 802.1x—to properly authenticate
network users against RADIUS servers.
When combined with Extreme Networks
Universal Port Manager (UPM), IT
administrators can dynamically provision
policies to associated network users
based on roles or UPM profiles.
-
Media Access Control (MAC) Security
MAC security allows the lockdown of a
port to a given MAC address and limiting
the number of MAC addresses on a port.
This can be used to dedicate ports to
specific hosts or devices and avoid abuse
of the port. In addition, an aging timer
can be configured for the MAC lockdown,
protecting the network from the
effects of attacks using (often rapidly)
changing MAC addresses.
-
IP Security
ExtremeXOS IP security framework
protects the network infrastructure,
network services and host computers
from rogue access, 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
traffic’s source from a specific address
for immediate defense.
-
Identity Manager
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.
-
Private VLANs
Private VLANs provide port-to-port
security to prevent unauthorized communication
of users within the same VLAN.
Unlike normal VLANs, ports enabled for
Private VLANs cannot communicate with
other ports in the same VLAN over Layer 2
or Layer 3. Private VLAN ports can only
communicate with a designated “uplink”
port. In addition, a Private VLAN provides
separation of broadcast domains within the
same VLAN.
Threat Detection and Response
-
CLEAR-Flow Security Rules Engine
CLEAR-Flow provides first order threat
detection and mitigation, and mirrors
traffic to appliances for further analysis of
suspicious traffic in the network.
-
Protocol Anomaly Detection
The Extreme Networks chipsets contain
built-in hardware protocol checkers that
support port security features for security
applications, such as stateless DoS
protection. The protocol checkers allow
users to drop the packets based on
conditions, which are checked for ingress
packets prior to the Layer 2/Layer 3
entry table.
-
sFlow
sFlow® is a sampling technology that provides
the ability to sample application-level traffic
flows on all interfaces simultaneously.
-
IPFIX
IPFIX (Internet Protocol Flow Information
eXport) defines an Internet standards-track
protocol for a follow-on protocol to the
proprietary Netflow. The technology is a
complementary protocol to sFlow. IPFIX
gathers information about network flows
through the switch and sends the information
to an external collector. Summit X480
includes hardware support to keep track of
the flow records.
-
Ðort Mirroring
Summit X480 supports many-to-one and
one-to-many port mirroring. This allows the
mirroring of traffic 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 ACLs
ACLs are one of the most powerful components
used in controlling network resource
utilization as well as protecting the network.
ACLs are used for filtering the traffic, as well
as classifying the traffic flow to control
bandwidth, priority, mirroring, and policybased
routing/switching.
-
Denial of Service Protection
Summit X480 effectively 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.
-
Secure and Comprehensive Network Management
Summit X480 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 X480
series switches 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 management
suite provides fault, configuration,
accounting, performance and security
functions, allowing more effective
management of Extreme Networks
multi-layer switching equipment in a
converged network.
For carrier networks, Extreme Networks
Ridgeline™ Service Advisor enables the
shift from reactive circuit monitoring to
proactive service monitoring. Ridgeline
Service Advisor unifies service fulfillment,
service assurance, and service engineering
so carriers can effectively manage next-generation
residential triple play, business
Ethernet and mobile Ethernet backhaul
services.
