Packet Tracer 7.1 has been under active development during Q1 and Q2 2017 and has ben realeased at the begining of August on Cisco Netacad website. The team focussed on correcting the stability issues encountered in Packet Tracer 6.3 & 7.0 versions and added quite a lot of new devices, including new cisco wireless simulation capabilities with WLC and lightweight access point.

Packet Tracer 7.1 new devices

The following devices have been added to Packet Tracer 7.1 :

Cisco 2504 wireless WLC

Packet Tracer 7.1 has a new Cisco 2504 Wireless LAN Controller (WLC) and Lightweight Access Point capabilities. The Lightweight Access Point connect to the WLC using CAPWAP tunnels and get their radio configuration (SSID) from it. The simulated WLC provides the following capabilities in Packet Tracer 7.1 :

  • CAPWAP tunnels
  • Multiple SSID with wlan to vlan mapping
  • WPA / WPA2 encryption (TKIP / AES) with 802.1x authentication support
  • Dynamic access point management interface
  • Internal DHCP server
  • DHCP proxy

Mobility management and rogue AP detection are not supported in Packet Tracer 7.1

Cisco 3702i Aironet Light Weight Access Point

Light Weight Access are centrally managed by a wireless controller. The WLC uses the CAPWAP protocol for Access Points registration and configuration.

The Cisco 3702i Aironet access points emulated in Packet Tracer 7.1 support the follwoing features :

  • PoE power supply (automatic when connected to a power inline enabled switch)
  • Local power supply (when PoE is not available)
  • DHCP client
  • Manual WLC address IP configuration
  • Power on auto provisionning with automatic WLC discovery using DHCP option 150

DHCP configuration for Light Weight access point automatic registration to a WLC using the 192.168.1.1 IP address

Cisco ISR 4321 Router

Packet Tracer 7.1 features a new Cisco ISR 4321 router with optical capabilities over (100BASE-FX and 1000BASELX/LH). This router runs IOS-XE unifying the 4000 Series Integrated Services Routers, 1000 Series Aggregation Services Routers. The Cisco ISR 4000 have been designed as multi-service branch office routers that has superior performance to the second generation ISRs, while the ASR 1000s series can serve as hight performance WAN edge router or aggregation service routers.

The Cisco ISR 4000 series also support IOX application, which extends  IOX hosting capabilities from small footprint routers, such as the ISR 819 routers which already allowed IOX simulation in Packet Tracer 7.0, to more powerful routers.

However, IOX features does not seem to have been implemented in the ISR 4321 emulated in Packet Tracer 7.1 . Only the securityk9 package is available :

IOS 15.5(3) for Cisco 1900 and 2900 ISR routers

Cisco Integrated Service Routers (ISR) 1941, 2901, and 2911 can be upgraded to IOS 15.5-3. Use the following steps to perform the upgrade :

Install a TFTP server and make sure it has these two files :

  1. c1900-universalk9-mz.SPA.155-3.M4a.bin
  2. c2900-universalk9-mz.SPA.155-3.M4a.bin

On each router, enter the following commands. Change the image file name accordingly to the ISR router model (1900 or 2900). Don't forget to save the configuration and to reload the router to boot on the new IOS image.

Router#copy tftp flash
Address or name of remote host []? 192.168.10.50 **TFTP server address**
Source filename []? c1900-universalk9-mz.SPA.155-3.M4a.bin
Destination filename [c1900-universalk9-mz.SPA.155-3.M4a.bin]? 

Router(config)#boot system c1900-universalk9-mz.SPA.155-3.M4a.bin

Router#write
Router#reload
Proceed with reload? [confirm]

MQTT messaging protocol for IoT devices

Packet Tracer 7.1 improves IoT objects communication by introducing an inovative MQTT messaging capability. MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. This lightweight protocol for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. It is also an ideal messaging protocol for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers

MQTT has been an OASIS Standard since 15 October 2014.

The following sample shows an example of MQTT messages available in Packet Tracer 7.1 . MQTT clients subscribe to MQTT message queues hosted by a MQTT broker. Those two functions are available in Packet Tracer SBC-PT IoT module

Bug correction :

This new version correct the following issues :

  • Crash when running "show ip ospf interface" command
  • Crash when moving from physcal to config menu of the 2901 ISR router
  • Crash when running entering the "service password-encryption" command on the ISR 829 router
  • Packet Tracer not remembering Netacad credentials -> login required at each application load
  • Home-VoIP-PT device does not save Server Address.
