What is Cisco Packet Tracer ?

Cisco Packet Tracer 8.2 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, security devices with ASA 5505 and 5506-X firewalls, and SDN controller

Packet Tracer 8.2.2 released !!

Update 06/04/2024 : A new Cisco Packet Tracer 8.2.2 version has been released for download on Netacad website. This is a bugfix release fixing several bugs on accessibility, usability, and security of Packet Tracer 8.2.

Packet Tracer 8.2.2 is a maintenance release of Packet Tracer 8.x serires which introduced a new SDN network controller as well as the API programming capabilities which can be accessed from the host PC using real world programming tools (curl, Python requests, VS code, ....)

Cisco Packet Tracer 7.2 splash screen

Packet Tracer 8.x also introduced a new GUI apearence as well as a new Packet Tracer splash screen.

CCNA 7.0.2 is only supported from Cisco Packet Tracer 8.2 64-bits which is the minimum version for new activities and new PTSA to work properly. Packet Tracer 7.2.2 is not available for download anymore.

Prepare ENCOR exam with GNS3

Compared with Cisco Packet Tracer, GNS3 runs real IOS images and emulates all the features of real Cisco ISR routers, Cisco security devices, L4/L7 appliances, ...

From GNS3 installation through the creation of complex simulated netwoks, this guide to GNS3 will give you the know-how needed for Cisco CCNP ENTERPRISE and CCIE certifications :

  • Install GNS3 on Windows, OS X, and Linux
  • Build simulations using Cisco routers, layer 3 switches, and Virtual PCs
  • Examine your simulated traffic with Wiresharks
  • Include virtualized computers into your simulations
  • Simulate Juniper and Vyatta routers
  • Debug using the GNS3 command console
  • [...]

Cisco Packet Tracer 8.2 ASA support

Cisco Packet Tracer 8.2 features Cisco ASA 5506-X firewall support. Firepower functionalities are not supported in this release.

Packet Tracer 8.2 ASA security

ASA 5506 firewall security concept

Discover how to configure clientless SSL VPN on ASA 5505 firewall and to setup a DMZ using Cisco Packet Tracer 8.2 .

Connect Cisco Packet Tracer to real network

Cisco Packet Tracer 8.0.0 SDN Controller and API can be accessed from outside of Packet Tracer using the host web browser or programming tools. Default port is TCP/58000 (http://localhost:58000). External Access has to be enabled in Packet Tracer global preferences and in config tab of the SDN Controller.

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.

PTBridge : Connect Packet Tracer with real world networks

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 !
