Cisco nexus series

  1. 1. 2K 5K 7K
  2. 2.  Nexus is a modular network switch introduced on January 28, 2008  Designed for the data center (optimized for high-density 10 Gigabit Ethernet.)  Its throughput is beyond 15 Tbps.  It has a modular NX-OS firmware/operating system
  3. 3.  The Nexus switches family range:  - Nexus 1000v virtual switch  - Nexus 2000 fabric extender  - Nexus 3000 series  - Nexus 4000 IBM Blade Center switch  - Nexus 5000 series  - Nexus 7000 series modular datacenter switches
  4. 4. Usability focused for demanding operational environments Delivers a unified fabric and I/O 15+ Tb/s scalable switching capacity
  5. 5.  The Cisco Nexus 7000 Series was designed around three principles: 1- Infrastructure scalability: Virtualization, efficient power and cooling, high density, and performance all support efficient data center infrastructure growth. 2-Operational continuity: The Cisco Nexus design integrates hardware, NX-OS software features, and management to support zero- downtime environments.
  6. 6. 3-Transport flexibility: You can incrementally and cost-effectively adopt new networking innovations and technologies, such as:  Cisco Overlay Transport Virtualization (OTV)  Cisco FabricPath  Fibrer Channel over Ethernet (FCoE)  Cisco IOS Multiprotocol Label Switching (MPLS)
  7. 7.  Nexus VS 65XX :  - Virtual port channel (VPC) : VPC is similar to VSS of the 65K's.  - Virtual device context (VDC) :  With VDC you virtually divide your switch up to 4 different virtual switches and allocate hardware resources to them  - 65K's can perform all the functions... Nexus still doesn't support service modules like FWSM, load balancers etc...
  8. 8.  Cisco Overlay Transport Virtualization (OTV):  - It makes multiple DC as one Dc.  - The NX7k switch has MAC add table for each NX7k switch  - The MAC add tables are automatically shared  - It stops spanning tree protocol  - In multicast : Just one copy sent to the core  Cisco FabricPath :  - Combines the simplicity of L2 domain with scalability of L3 domain , Creates (L2 routing tables)  - No blocking , send through all links, down link will be excluded.  - Shortest path will be used  - Add fabricpath Switch destination header  - Add server any where in the dc
  9. 9.  Fiber Channel over Ethernet (FCoE) :  - Allow the server to connect to the San and the LAN through one link  Hitless software upgrade by :  - In Service Software Upgrade (ISSU)  Cisco Data Center Network Manager:  - Management tool
  10. 10.  Nexus 7000 Hw specifications :  - Delivers high-density 10, 40, and 100 Gigabit Ethernet  - provide parallel fabric channels to each I/O and supervisor module slot  - Up to five simultaneously active fabric modules work together delivering up to 230 Gbps per slot  46 Gbps per slot per fabric ( 46*5 fabric = 230 Gbps per slot )  - 46 is for fabric 1 , in fabric 2 its 110 per slot  - With 550G per slot, scales to more than 17 Tbps switching capacity
  11. 11.  New Nexus 7000 Supervisor Engines :  - Cisco Nexus 7000 Series Supervisor 2 and 2E Modules deliver increased control plane performance and system scalability  - Cisco Nexus 7000 Series Supervisor 2 has twice the CPU performance of the Supervisor 1 Module  - Cisco Nexus 7000 Series Supervisor 2E performance is Four times the CPU performance of the Supervisor 1 Module
  12. 12.  Simpler More Stable Layer 2 Network  Highly Available Platform  Preserves operational best practices  FCoE based Unified Fabric  Virtualization Optimized Networking  Support for GE, FCoE, DCE, and FC  Reduces power, cooling, cabling  Up to 52 non-blocking 10GbE  Up to 1.2 Tbps capacity Infrastructure Scalability Transport Flexibility Operational Continuity
  13. 13. 56-Port L2 Switch • 40 Ports 10GE/FCoE/DCE, fixed • 2 Expansion module slots Cisco DC-OS FC + Ethernet • 4 Ports 10GE/FCoE/DCE • 4 Ports 1/2/4G FC Fibre Channel • 8 Ports 1/2/4G FC Cisco DC-OS Ethernet • 6 Ports 10GE/FCoE/DCE DC-NM and Fabric Manager NX-OS
  14. 14. Nexus 5000 Platform
  15. 15. - NX-OS two images kickstart image and system image. - Not all the features are enabled by default... for example if you want to use OSPF... you firstly have to enable the feature. ... (feature ospf) - All the features are licensed... This is not very bad... considering that an enterprise licenses gets almost all of your features running.
  16. 16.  You don't have to prefix "do" in front of your "privilege level show commands" if you are in configuration mode  The routing protocol configuration is more on the interface level like in IPV6... ipv6 enable  NX-OS CANNOT NAT"; no NAT command on NX-OS... unusual as it is one of the common L3 feature on any cisco device.  No F and GE in the commands … all are Ethernet  There aren't any speed designations in the interface name.
  17. 17.  no "write" command you have to use the big old "copy run start“  The " sh tech-support" gives you never ending data... its HUGE MB's of data  Supports VTP only in transparent mode  - Doesn't support PAGP supports only LACP  - It doesn't support EIGRP unicast neighborship...  The "sh run" has a lot of minor components which makes it easier to look at the configuration... like "sh run rpm"(route processor module) : gives you all the route policy config like route-maps and prefix lists
