CISCO NEXUS SERIES2K 5K 7K

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 system

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

Cisco Nexus 7000 SeriesData Center Class Switches

Usability focused for demanding operational environments

Delivers a unified fabric and I/O

15+ Tb/s scalable switching capacity

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.

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)

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...

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

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

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

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

NX-OS

Nexus 5000 Platform

- 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.

NX-OS :

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.

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

Thank you
