What is Cisco Packet Tracer ?

Cisco Packet Tracer 7.3 is a powerful network simulator for CCNATM and CCNPTM certification exam training allowing students to create networks with an almost unlimited number of devices and to experience troubleshooting without having to buy real CiscoTM routers or switches.

Cisco Packet Tracer features an array of simulated routing & switching protocols with STP, HSRP, RIP, OSPF, EIGRP, and BGP to the extent required by the current Cisco CCNA curriculum as well as application layer protocols (HTTP, DNS, …) to simulate network trafic .

It also includes Cisco IOS 15 with licence features, wireless capabilities with WLC and lightweight access point, and security devices with ASA 5505 and 5506-X firewalls.

PTBridge : Connect Cisco Packet Tracer to real network

An open source version of PTBridge 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 available for download !

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.

Cisco Packet Tracer Mobile LAN lab example with simulated traffic

This mobile version is based on the new Cisco Packet Tracer 7.0 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 Cisco netacad 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.

Download TSHOOT topology for Cisco Packet Tracer 7.3

Cisco CCNP TSHOOT (300-135) is a qualifying exam for the Cisco CCNP certification. It differs from the CCNP SWITCH and CCNP ROUTE exams by requesting the exam candidate to work on simulated troubleshooting tickets. The network topology of the tickets is publicly available on Cisco website.

CCNP TSHOOT topology lab for Cisco Packet Tracer 6.1

This CCNP TSHOOT lab is available in Cisco Packet Tracer 7.3 to help students to prepare the exam by beeing comfortable with the exam network topology and concepts before taking the exam.
