Cisco Nexus series high capabilities with fastest switching.

1. 2K 5K 7K

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.  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. Usability focused for demanding
operational environments
Delivers a unified fabric and I/O
15+ Tb/s scalable switching capacity

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. 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.  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.  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.  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.  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.  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.  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

NX-OS

14. Nexus 5000 Platform

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.  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.  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
