Packet Tracer 7.0 build 202 has been released on 17 June 2016. This new Packet Tracer version, which has been under active testing for 6 month, is the first Packet Tracer release including Internet of Everything features linked with the CCNA Industrial exam (CCNA IMINS2). This new version is expected to fix an OpenSSL vulnerability affecting multiple Cisco products (bug CSCuy54539 for Packet Tracer 6.x) but no confirmation has been issued for the moment.

An IoE (Internet of Everything) tab has been added to the server device. Three new Cisco routers and an IE2000 industrial switch were also added. Packet Tracer 7.0 features a lot of new protocols (LLDP, PTP, ...) and bug correction. As Packet Tracer 6.3, a Netacad account is required to access to the software. However, everyone is now able create a Netacad account, download Packet Tracer 7.0 for free, and get an introduction to Packet Tracer. Packet Tracer 7.0 new features.This is a very good news for CCNA self learners preparing the simulation questions of the CCNA exam !!


Leaked information (unconfirmed) in the last 6 month

Wireless IoE devices could also be added to this future Packet Tracer 7 version but no détails have leaked for the moment. Packet Tracer 7.0 could also provide Smart Cities scenarios with wireless connected cars. A lot of testing happened on Smart Cities features at the end of July but the development team seems to hava quite a lot of remaining crash problems.

A virtual version of the Cisco Nexus 9000 datacenter switch is now available for CCNP Datacenter training : Nexus 9000v (or NX-OSv 9000) switch. All the Nexus 9000 features are supported except the following table :

NX-OS Features



Not supported on NX-OSv 9000.


Not supported on NX-OSv 9000.


Not supported on NX-OSv 9000.

Policy maps

Not supported on NX-OSv 9000.

ARP Suppression

Not supported on NX-OSv 9000.


Not supported on NX-OSv 9000.

IGMP Snooping

Not supported on NX-OSv 9000.


Not supported on NX-OSv 9000.


Not supported on NX-OSv 9000.


Not supported on NX-OSv 9000.

Nexus 7000 Titanium NX-OS simulator has been included by Cisco in their new VIRL (Virtual Internet Routing Lab) simulation platform. Compared to Packet Tracer  VIRL uses real cisco IOS, IOS-XR, NX-OS images running in virtual environments. The NX-OS simulation platform is now named NX-OSv and features a Nexus 7000 switch running NX-OX v7.2 . NX-OSv can be used in GNS3 labs and linked to other Cisco devices like CSR1000V or other vendors simulated devices. This new simulation environment will help students preparing CCNA datacenter or CCNP by overcoming Packet Tracer limitations.

Zone based firewalling in Cisco Packet Tracer

3.9285714285714 1 1 1 1 1 Rating 3.93 (14 Votes)

Zone based firewalling is available in Cisco Packet Tracer 2800 routers with IOS 12.4(15)T1 and in new 2901/2911 ISR routers with IOS 15.1(4). This feature was introduced by Cisco in IOS 12.4(6)release.

The zone-member command seems to be only available on 2811 router's FastEthernet interfaces. It is not available on vlan interfaces of this router or in a 2911 router.

VLAN managment on Cisco ISR routers

5 1 1 1 1 1 Rating 5.00 (2 Votes)

VLAN managment is quite different on ISR routers than on Catalyst switches. VLAN can be used as 802.1q subinterfaces for routed interfaces or with more switch-like configuration on Ethernet Switch Modules (HWIC-4ESW for example)

VLAN configuration (subinterface)

Coming soon

VLAN configuration (internal switch)

Router(config)#interface Vlan100
Router(config-if)#description mgmt
Router(config-if)#ip address

Router#vlan database 
% Warning: It is recommended to configure VLAN from config mode,
  as VLAN database mode is being deprecated. Please consult user
  documentation for configuring VTP/VLAN in config mode.

Upgrade router/switch IOS version

4.1875 1 1 1 1 1 Rating 4.19 (16 Votes)

It is possible to upgrade the IOS of a device in Cisco Packet Tracer.

1. Put the TFTP server into the workspace
2. Click on it to open its properties
3. Go to the Config tab, then click TFTP. This will show you different IOS versions which can be downloaded on a router or switch device.

You can delete the IOS that is in flash of a router. After reloading the router, it will boot to rommon mode. You can then download an IOS version from the available ones on the TFTP server.

Since Packet Tracer 6.1, IOS 15.x has been available in Packet Tracer for ISR routers as well as catalyst 2960 switch
