SummitStack-V80/V160/V320—Flexible Stacking Over 40 |
GREEN DESIGN – LOW POWER CONSUMPTION |
Gigabit Ethernet |
WITH OPTIMIZED COOLING OPTIONS |
The Summit X670-G2-48x-4q also supports high-speed 80Gbps,160 Gbps, and 320Gbps stacking using QSFP+ ports, which is ideal for demanding applications where a high volume of traffic traverses through the stacking links, yet bandwidth is not compromised through stacking. SummitStack-V80, -V160, and -V320 can support passive copper cables (up to 1m), active multi-mode fiber cable (up to 100m), and QSFP+
optical transceivers for 40 GbE up to 10km. With SummitStack, the Summit X670-G2-48x-4q provides a flexible stacking solution inside the data center or central office to create a virtualized switching infrastructure across rows of racks.
Intelligent Switching and MPLS/H-VPLS Support
Summit X670-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, Summit X670-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
1588 Precision Time Protocol (PTP)
Summit X670-G2 offers 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 X670-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.
Low Latency Switching for Cluster Computing
Summit X670-G2 can achieve latency less than 600 nanoseconds and supports cut-through switching for latencysensitive cluster computing.
The Summit X670-G2 series is designed to be environmentally green. System power consumption is very low at both highload and idle situations through the power-efficient hardware design. The power supplies are also highly efficient, which minimizes the loss of power and unnecessary heat generated by the power supply. Summit X670-G2 series switches can be used in AC or DC powered environments.
DESIGNED FOR CLOUD DATA CENTERS – VEPA, XNV, DCB, OPENFLOW, OPENSTACK
Summit X670-G2 has a variety of features that fit your data center needs:
DIRECT ATTACH (VEPA)
With the optional feature pack, Summit X670-G2 switches can 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.
DATA CENTER BRIDGING (DCB)
The Summit X670-G2 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.
PFC
Summit X670-G2 switches support Priority-based Flow Control (PFC, or IEEE 802.1Qbb), which allows network traffic to be controlled independently based on Class of Service. PFC allows network traffic that requires lossless throughput to
be prioritized,while other traffic types that do not require or perform better without PFC can continue as normal.
SOFTWARE DEFINED NETWORKING (SDN) OPENFLOW
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 offer a programming interface through OpenFlow to enable a high degree of automation
in provisioning network services for many upper layer businesscritical applications running the OpenFlow-based SDN controller.

OPENSTACK
ExtremeXOS-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 APIdriven system that enables networking-as-a- service model managing data center interconnect solutions and large multitenant networks.
VIRTUAL ROUTERS
In a virtualized environment there is a requirement to support multiple tenants. In an effort to isolate tenants from each other, logical separation is established at Layer 3 and Layer 2 level. ExtremeXOS supports multiple, isolated Layer 3 forwarding domains by way of Virtual Routers.
ENTERPRISE CORE CLASS SCALABILITY
The Summit X670-G2 series offers more cost-effective 10 Gigabit Ethernet switches, for both small-sized core
backbone and traditional three-tier network architectures. Summit X670-G2 series can support 10 Gigabit Ethernet campus aggregations with its core class routing and switching scalability.
ONE OPERATING SYSTEM
Extreme Networks simplifies network operation by offering one common OS – ExtremeXOS – throughout the BlackDiamond and Summit portfolio. From 10/100 Mbps
switching products such as Summit X430 and Summit X440 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.
Modular Operating System for Non-Stop Operation
LOADABLE SOFTWARE MODULES
The modular design of the ExtremeXOS OS allows the adding or upgrading of individual software modules dynamically without requiring a system reboot, leading to higher availability in the network.
PREEMPTIVE MULTITASKING AND PROTECTED MEMORY
Summit X670-G2 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 cross-platform 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.
Rich OAM Suite – CFM, Y.1731, BFD
Summit X670-G2 series switches supports a rich suite of protocols to help with Operations, Administration and Maintenance. Connectivity Fault Management (CFM) allows detection, verification, and isolation of connectivity failures in virtual bridged LAN. Y.1731 is largely similar to CFM but also supports performance management by way of frame delay and frame delay variation measurements. Bidirectional Forwarding Detection (BFD) is a hello protocol that provides
the rapid detection of failures in the forwarding path and helps the separation of control plane connectivity from forwarding plane connectivity. By having multiple control plane protocols like OSPF or MPLS rely on BFD to detect forwarding plane connectivity failures, network operators can benefit from simpler network profiling and planning, and consistent and predictable re-convergence times.
MPLS
On the Summit X670-G2 series switches MPLS can be enabled, if needed, by way of an optional feature pack. MPLS provides the ability to implement traffic engineering and multi-service networks, and improve network resiliency. The MPLS protocol suite provides the ability to deploy services based on L2VPNS (VPLS/VPWS), BGP-based L3VPNS; LSP Establishment based on LDP, RSVP-TE, Static provisioning; Integrated OAM tools like VCCV, BFD and CFM; And MPLS Fast Reroute to support rapid local convergence around network failures.
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 can achieve sub-second recovery that delivers consistent failover regardless of the number
of VLANs, network nodes or network topology in Extreme Networks-recommended configurations.. EAPS functionality increases network recovery time, which results in significant reduction in Voice-over IP call drop rates and improvement in digital video performance in supported solution configurations.

SPANNING TREE / RAPID SPANNING
TREE PROTOCOLS
Summit X670-G2 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 X670-G2 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.
Robust IP and 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 effects of attacks using (often rapidly) changing MAC addresses.
IP SECURITY
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 traffic’s source from a specific address for immediate defense.
LINK AGGREGATION (802.3AD)
Link aggregation allows trunking of up to 32 links on a single logical connection, for up to 320 Gbps of redundant bandwidth per logical connection.
MULTI-SWITCH LAG (M-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.
HARDWARE REDUNDANCY
Summit X670-G2 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-G2 also supports standardized N+1 redundant hotswappable fan units.
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.
