Switch Cisco Nexus N2K-C2248TP

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, as well as Root Guard, BPDU Guard etc.., port aggregation Port Channel and t. d. Also, switches Cisco Nexus support L3 Functional 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), restriction of access at the port level (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 «parental» 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 CiscoNexus 2000 Series – these are fixed configuration devices with up to 48 10 Gigabit Ethernet ports, as well as up to 4 10x4 Gigabit Ethernet ports, form factor 1RU, capable of transmitting per second up to 1,2 Tbps data, and at any moment you can switch from the network 10 Gigabit Ethernet On the 40 Gigabit Ethernet. devices Cisco Nexus Series 2000 run on an operating system Cisco NX - OS. This operating system is able to process operations that help the equipment cope with such complex tasks..

To the main features of the switches Cisco Nexus 2000 series include models with 24, 32 or 48 Ethernet ports, ports with support for standards 100/1000 and 10G Ethernet and with work through different transmission media using SFP/SFP+ modules, plug-and-play connectivity and automatic initial configuration. devices Cisco Nexus 2000 work only in conjunction with older models Cisco Nexus 5000 and Cisco Nexus 7000 (New models can be installed together with series switches Nexus 5500, 5600 and 6000 as mother, and in the future will also support series Nexus 7000 and 9000). Standard copper cables can be used to communicate with the main chassis. CX1, single or multimode optics, as well as special economical Cisco Fabric Extender Transceivers (FET).

Also, a series Cisco Nexus 2000 presented systems Cisco Nexus 2300. These models, among other things, also provides for the possibility of dividing ports 40G for the organization to 64 ports 10G (this feature is useful in data centers that are moving their servers from gigabit to 10 gigabit connections). Six 40G ports support optical transceivers Cisco BiDi bi-directional, so 10G to 40G uplink upgrades can leverage existing cabling, saving on cable relocation and speeding up network upgrades.
