Today a blog post on something I hope you will find useful: How to build a virtual Cisco Nexus lab on VMware vSphere. The goal is to create a lab containing two or more virtual Cisco Nexus switches, which can be used to learn/test NX-OS. You can use the Titanium emulator for this setup, which has been to the internet. Just use Google to find it. The lab which is discussed in this article runs on vSphere/ESXi and is built according to the following design: The configuration consists of:.
Two Nexus 7000 switches (bases on a simulator);. For management of the switches you have a serial port and an SSH connection available. The serial port is connected to the management LAN using the serial-port-to-network feature of ESXi.
For the SSH connection Nexus port “mgmt 0” is configured and connected to the management LAN. On the first switch (N7K-1) port e2/1 is connected to the 192.168.192.0/24 network, and port e2/2 is connected to the 172.30.96.0/24 network;. On the second switch (N2K-2) port e2/1 is connected to the 172.30.96.0/24 network, and port e2/2 is connected to a third network with subnet 172.30.97.0/24. Building the Nexus lab The Titanium emulator comes as a set of files which can be uploaded to a VMFS/NFS datastore on an ESXi host.
After registering the virtual machine it becomes available in your vSphere inventory. The default NICs in the emulator won’t work with ESXi, so remove them and add E1000 adapters. Also remove the serial port (if available) and add a new serial port to your virtual Nexus switch.
Explains how you can access the Nexus serial port through a telnet connection. The configuration of the Titanium virtual machine should look like this: For the N7K-1 switch (displayed in the image) add (for example) 7 adapters to the switch and a serial port:. The serial port can be connected through Telnet on port 6001;. Network Adapter 1 is the mgmt 0 interface on the Nexus;.
Network Adapter 2-7 are devices e2/1-6 on the Nexus;. The nxos-mgmt = the management network;. LAN network is not connected or used at this point. Network Adapter 3 (e2/2) is connected to the 172.30.96.0 segment, which is actually a Virtual Machine portgroup name on the ESXi host. Nexus N7K-2 is also connected to this segment: vSwitch1 is deployed to interconnect N7K-1 and N7K2. After booting the switches you first have to access the switch through the serial port. After this you can set an IP address on the ‘mgmt 0’ interface to access the switch through SSH.

My topology: R1′s e2/2 —————-R2′s e2/2 both e2/2 belong to LAN2 in network settings.

Cisco Packet Tracer features an array of simulated Application layer protocols (HTTP, DNS, ), as well as basic routing with RIP, OSPF, and EIGRP, to the extent required by the current. It also includes Cisco IOS 15 with licence features which was introduced in the CCNA exam in 2013. Cisco Packet Tracer 7.1 was released in August 2017 with quite a lot of new devices and features, including for the first time emulated Cisco wireless capabilities with WLC and lightweight access point. New firewalling capabilities are also included with the Security Plus ASA licence. Released on June 2016, included 3 new ISR routers with wireless capabilities (ISR819IOX, ISR829,.), a new IE2000 industral switch, and. Python and javascript scripting capabilities have also been added to program IoT sensors behavior.
With command line configuration (but no Adaptive Security Device Manageror CCP tools). It also started collector support as a Desktop application in the server device, routing protocols for IPv6 (OSPFv3, EIGRPv6, RIPNg), DHCP snooping commands, IPv6 CEF, IPSEC. Packet Tracer 6.2 also introduced 3G/4G telephony support as well as a new Cisco 819 ISR router with a.
OSPF and EIGRP enhancements were also added in this version. In a rapidly growing IoE market, Cisco announced new Industrial/IoT certification ( IMINS2 Exam) program to help students and network professionnals to builds the skills required to converge Industrial Plant floor with IT infrastructure. Packet Tracer 7.0 provides advanced IoE capabilities with the following new devices and features:.
MCU and SBC IoT boards with wired and wireless connectivity. New IoE service in server device and IOE home Gateway with centralized modular programming capabilities (javascript, python). IoX application deployment capabilities on ISR819HG-4G IOX router. Several IoE activities such as an I2IoE 'Home IoE Implementation' lab.
An open source version of is now available on GitHub. This PTBridge version works with Packet Tracer 6.2 multiuser connection (server mode). It translates Packet Tracer packets and protocols to real ones and allows real network interaction with Packet Tracer simulated environment. ASA features such as IPSEC VPN or SSL clientless will be tested soon. Wait for upcoming test results!

Since Cisco Packet Tracer 5.3.3, it has been possible to connect Cisco Packet Tracer simulated environment to real world networks using PTBridge which is an external java application (PT533-Bridge-1.0.11.jar for Cisco Packet Tracer 5.3.3) working with the following components:. Java JRE 6. WinPcap v4.1.2 (captures the packets). JnetPcap v1.3.0 (decodes the captured packets). Packet Tracer multiuser cloud configured on TCP 38000 port. Cisco Packet Tracer Mobile 3.0 has been released by Cisco on may 12th, 2017.
This is the fourfth Packet Tracer version released by Cisco for android and apple mobile devices. Cisco Packet Tracer Mobile 3.0 is still not available for windows phones. However, Packet Tracer 7.0 PC version is available and fully functionnal on Windows 10 tablets.
This mobile version is based on the new simulation engine including IoT capabilities and is thus compatible with Cisco Packet Tracer 6.3 and 7.0 labs. This new version also corrects bugs fonds in previous the previous Packet Tracer Mobile 2.1 version. Limitations and differences with Cisco Packet Tracer 7.0 desktop version can be found in the release notes available on website.
A free Cisco Networking Academy Netspace account is required to use the full features of the simulation software. Packet Tracer mobile 3.0 requires Android 4.2 on ARMv7 CPU tablets.

User interface is optimized for screens with a minimum size of 7 inches and is as such difficultly usable (but working) on a phone.
Cisco UCS Manager Simulator This tutorial will walk you through the few steps required to setup the Cisco UCS Manager Simulator. To download the Cisco UCS Manager Simulator you will require a Cisco login. I’m using version 2.2.1b in this tutorial. You can download the latest version of the Cisco UCS Manager Simulator and User Guide here: Installing the Cisco UCS Manager Simulator 1. There are 2 options when you download the Cisco UCS Manager Simulator, downloading the package as an OVF/OVA or as VMDK files. I opted for the VMDK option.
I uploaded the folder to my VMware ESXi datastore and then registered the VMX file with my vCenter server which created the Virtual Machine for me. After registering the Virtual Machine I powered it on. Once the command prompt appears asking you to login enter the default username and password of, User: config and Pass: config. You will then be presented with the following menu. Press (a) to configure the Network settings. You will require 3 IP addresses for eth0, eth1 and eth2. Enter in the subnet mask and lastly the IP addresses for the default gateway.

The wizard will configure the simulator with the IP addresses and you will then be ready to login. Use Chrome or Firefox and enter in the address of the IP you set for eth0. In my example I used 192.168.1.92, so I will browse to 5. Clicking on Start-up Inventory on the left hand side will give you the option to add extra UCS hardware to the Simulator. Out of the box you will get 1 chassis configured for you which includes 6 blade servers along with 2 x Interconnect switches 6. Clicking on UCS Manager on the right hand side and selecting UCS Manager Home, you can click on the Launch UCS Manager button.
This will ask you to authenticate. Use the default username and password of User: config and Pass: config. You are now logged into your Cisco UCS Manager Simulator. You can then begin to configure your Organisations, Policies, Templates, Service Profiles etc. To shutdown the virtual machine go back to the Cisco UCS Platform Emulator Control Panel, click on Restart at the right hand side and select power down virtual machine.
