Switch Cisco Nexus N5K-C5648Q

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 Cisco Nexus 5000 are a line of switches with a high density of ports, at speeds 10 GigabitEthernet and 40 GigabitEthernet, Cisco Data Center Ethernet (DCE) and Fibre Channel over Ethernet (FCoE). This series of switches uses cut-through switching and maintaining low switching latency regardless of packet sizes and enabled services. Cisco Nexus 5000 Provide data transmission over Ethernet network to 2 and 3 switching levels and storage traffic on one unified platform. Multiprotocol Cisco Nexus 5000 well suited for industrial and average network data centers.

Of the features devices Cisco Nexus 5000 series can be distinguished up to 96 unified ports, flexibility of architecture and extensions, high reliability of software, operating system Cisco NX-OS, high transmission speed networks Ethernet (10GbE, 40GbE, FCoE, DCE), including layer 2 and 3 traffic as well as traffic SAN, support for virtualized and cloud deployments, support for FabricPath for second-level networks, latency of all ports – 1 millisecond and single point of control. Switches Cisco Nexus Series 5000 Provide an advanced security system, which avoids unauthorized penetration, as well as high fault tolerance in any loads.
