  3. 3. Introducing Cisco Nexus Family:  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 systemPresentation_ID © 2006 Cisco Systems, Inc.

  4. 4. 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 switchesPresentation_ID © 2006 Cisco Systems, Inc. All rights reserved. 4
  5. 5. The Cisco Nexus 7000 Series  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.Presentation_ID © 2006 Cisco Systems, Inc.

  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)Presentation_ID © 2006 Cisco Systems, Inc.

  8. 8. Nexus VS 65XX : - Virtual port channel (VPC) : VPC is similar to VSS of the 65Ks. - Virtual device context (VDC) : With VDC you virtually divide your switch up to 4 different virtual switches and allocate hardware resources to them - 65Ks can perform all the functions... Nexus still doesnt support service modules like FWSM, load balancers etc...Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. 8
  9. 9. 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 dcPresentation_ID © 2006 Cisco Systems, Inc.

  10. 10. 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 toolPresentation_ID © 2006 Cisco Systems, Inc.

  11. 11. 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 capacityPresentation_ID © 2006 Cisco Systems, Inc.

  17. 17. Day 2: IOS VS XOSPresentation_ID © 2006 Cisco Systems, Inc. All rights reserved. 17
  18. 18. NX-OS : - 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.Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. 18
  19. 19.  You dont 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 arent any speed designations in the interface name.Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. 19
  20. 20.  no "write" command you have to use the big old "copy run start“  The " sh tech-support" gives you never ending data... its HUGE MBs of data  Supports VTP only in transparent mode  - Doesnt support PAGP supports only LACP  - It doesnt 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 listsPresentation_ID © 2006 Cisco Systems, Inc.

  25. 25.  NX-OS has a setup utility that enables a user to specify the system defaults, perform basic configuration, and apply a predefined Control Plane Policing (CoPP) security policy.  Two preconfigured instances of VPN Routing Forwarding (VRF) by default (management, default).  By default, all Layer 3 interfaces and routing protocols exist in the default VRF.  The mgmt0 interface exists in the management VRF and is accessible from any VDC.  Each VDC has a unique IP address for the mgmt0 interface.Presentation_ID © 2006 Cisco Systems, Inc.
