Cisco Packet Tracer network simulation software logo

Cisco Packet Tracer is a powerful network simulator that can be utilized in training for CCNA TM and CCNP TM certification exam by allowing students to create networks with an almost unlimited number of devices and to experience troubleshooting without having to buy real Cisco TMrouters or switches.


Cisco Packet Tracer supports 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 CCNA TM curriculum. The new IOS 15 added in the 6.0.1 version is a chance for students to prepare for the new CCNA curriculum. With the introduction of versions 5.3 and 6.0, several new features were added, including BGP and HSRP, which are part of the CCNP TM curriculum. Despite some feature limitations, students preparing CCNP Route and CCNP Switch exams are also able to simulate basic IP telephony with Cisco Call Manager Express and IPSEC VPN using Cisco 2811 routers.


While Cisco Packet Tracer aims to provide a realistic simulation of functional networks, the application itself utilizes only a small number of features found within the actual hardware running a current Cisco IOS TM and focuses on CCENT / CCNA preparation. Work on Cisco hardware (switches & routers) or GNS3 simulation software is hardly recommended for a good preparation for CCNP exam simulation questions.


After months of waiting, Packet Tracer 6.1.1 has finally been released by Cisco in late August 2014. The new Packet Tracer version has been released with the version number 6.1.1 and is available in two versions : "Cisco Packet Tracer Student" and "Cisco Packet Tracer Instructor". This new version includes a Cisco ASA 5505 firewall with command line configuration (but no Adaptive Security Device Manageror CCP tools). It also includes a netflow collector as a Desktop application in the server device, routing protocols for IPv6 (OSPFv3, EIGRPv6 , RIPNg), DHCP snooping commands, IPv6 CEF, IPSEC ...
Update 15/12/2014 : The next Packet Tracer version will probably be Packet Tracer 6.2. This version is currently under development and Packet Tracer (build 33) is the last know beta build as of Decembre 15, 2014. Testing and bug reporting activity seems to have decreased for a few weeks.
Despite very little information has leaked about Packet Tracer 6.2 on the Internet, you can follow the bug tracking activity of the future version on our Packet Tracer 6.2 page.


Cisco Packet Tracer Mobile 1.0 for Android

Packet Tracer Mobile 1.0 is the first Packet Tracer version released by Cisco for android tablets. Packet Tracer Mobile 1.0 is not available for windows 8 or ipad devices.

This mobile version is based on the Packet Tracer 6.1 simulation engine and is thus compatible with PT 6.1 labs. Limitations and differences from Packet Tracer 6.1 desktop version can be found in the release notes.

What is Cisco Networking Academy ?

Cisco Networking Academy (netacad) is a Cisco Systems education program which goal is to prepare students for certification exams such as CCNA, CCNP, ... Courses are available in about 9000 local academies over 165 different countries around the world. Packet Tracer can be freely downloaded from Cisco web site by students and instructors members of the netacad program.


Update 17/09/2014 : The Cisco networkinh academy CCNA Routing & Switching 5.0 course material (pka files, ...) is affected by Packet Tracer 6.1.1 bug fixes. Cisco released an updated version of CCNA Routing & Switching (v5.02) to addess this problem. The new material is not backward compatible with previous Packet Tracer versions. Have a look on cisco official website for more informations about this issue.

PTBridge : Connect Packet Tracer to real network

Since Packet Tracer 5.3.3, it has been possible to connect Packet Tracer simulated environment to real world networks using PTBridge which is an external java application (PT533-Bridge-1.0.11.jar for 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.

Packet Tracer 6.1 bug #16605

The following bug has been reported for ASA device in Packet Tracer 6.1.1 and 6.2 beta build 20 :

1. All PCs have as their gateway from DHCP. Triggering a new DHCP request results the same.


2. Issue commands on ASA:
dhcpd dns int inside
dhcpd domain TEST int inside

Do 'show run' and notice these are missing.


3. Issue command on ASA:
no dhcpd auto_config outside

Save the config, save the file, and reload the file. Do 'show run' and
'dhcpd auto_config outside' will still be there.
