switches Cisco Nexus – is a series of network switches in fixed and modular configuration, designed primarily for installation in data centers or for installation in a corporate network as a network core.
Series devices Cisco Nexus support virtual networks (VLAN, Private VLAN), loop prevention protocols STP, and Root Guard, BPDU Guard etc.., port aggregation Port Channel and t. d. Also, switches Cisco Nexus support L3 functionality including static and dynamic routing (EIGRP, OSPF, BGP, ISIS), policy-based routing (PBR), support for default gateway redundancy protocols (HSRP, VRRP, GLBP), GRE-tunnels and t. d. Supported protocols for working with multicast traffic: IGMP And PIM.
Security in devices is represented by access lists ACL (IP, MAC, VLAN), port level access restriction (Port Security), various functions to combat address spoofing (DHCP snooping, Dynamic ARP inspection, IP source guard). There are mechanisms to deal with broadcast storms (Storm Control) and control level protection (Control Plane Policing). For monitoring and control there is SNMP, NTP, Netflow, various implementations SPAN, Embedded Event Manager and more, while supporting the ability to manage through the network management protocol NETCONF, as well as running scripts based on Python. switches Nexus support a fairly large range of other various technologies: MPLS, LISP, VXLAN, OTV, QoS (functionality depends on the platform).
Switch line Cisco Nexus includes such series:
- Nexus 1000 Series — virtual switch that is used in VMware vSphere And Hyper-V
- Nexus 2000 Series — fabric-extender, control and management is carried out through the "parent" equipment
- Nexus 3000 Series - network switches mounted in a telecommunications rack, a feature of this type of switches is the support of technology VXLAN
- Nexus 4000 Series - high-speed switches supporting the technology 10 Gigabit Ethernet, built on integrated circuits ASIC. Developed in collaboration with the company IBM, like a blade IBM BladeCenter
- Nexus 5000 Series - Layer 3 network switches mounted in a telecommunications rack, except LAN also provide switching SAN traffic. Switches run at speed 10 Gigabit Ethernet And 40 Gigabit Ethernet. Switches support technologies: Fibre Channel, FCoE, VXLAN And NVGRE
- Nexus 6000 Series - Layer 3 network switches may have up to 96 ports 40 GigabitEthernet or up to 384 ports 10 GigabitEthernet
- Nexus 7000 Series - modular switches, have a bandwidth of up to 1,3 Tbps for each slot (blade) or more than 83 Tbps on chassis
- Nexus 9000 Series - in addition to low-end technologies, supports MPLS-VPN (BGP-EVPN)
switches Cisco Nexus series 9000 provide the basis for infrastructure deployment Cisco, application oriented (ACI - application centric infrastructure), which are able to provide scalability, high performance, low power consumption, as well as the full operation of network virtualization technologies VXLAN (Virtual Extensible LAN) And NVGRE (Network Virtualization Using Generic Routing Encapsulation). They provide high scalability, performance and power efficiency in a compact size device.. These switches are ideal for aggregation and access layer deployments in large enterprise, service provider, and cloud networks..
switches Cisco Nexus 9000 available in modular and fixed configuration 10/40/100 Gigabit Ethernet and designed to work in modee Cisco NX for backwards compatibility and consistency with the current set of solutions Cisco Nexus, and in modee ACI to take full advantage of policy-based services and infrastructure automation features ACI.
Devices Cisco Nexus 9000 series are highly scalable, up to 60 Tbps (chassis Nexus 9516) less than 5 microsecond latency non-blocking bandwidth, and up to 1152 non-blocking ports 10 GigabitEthernet or 288 non-blocking ports 40 GigabitEthernet layer 2 and 3, as well as support for relaying, routing and gateways in the network VXLAN at wired speeds. Device high availability Cisco Nexus 9000 series characterized by full support for software updates without interruption (ISSU) and making corrections to the software without interruption, and the use of specialized integrated circuits (ASIC) Cisco and third parties to improve reliability and performance. Also, Chassis without intermediate board optimizes airflow and reduces power consumption.
