New features in Packet Tracer 7.3

Dynamic ARP Inspection

Based on DHCP snooping, dynamic ARP inspection (DAI) is a security feature rejecting ARP packets in which advertised MAC address does not match any DHCP snooping entry for the switch port on which the ARP packet has been received. This behaviorpreventsman-in-the-middle attacks, where an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting neighbors.

Packet Tracer 7.3 dynamic arp inspection lab topology

DAI relies on DHCP snooping switch database. DHCP snooping listens to DHCP message between DHCP clients and DHCP servers. It builds a bindings database of valid tuples (MAC address, IP address, VLAN interface).

A sample Dynamic ARP Inspection lab is provided with Cisco Packet Tracer 7.3

Cisco Packet Tracer 7.3 has been released ! Current build is Packet Tracer 7.3.0.0838. Have a look at Cisco Packet Tracer 7.3 new features

 

Packet Tracer 6.2 has been released in february 2015 with version number 6.2.0.0052 (Packet Tracer 6.2 build 52). This new version is available in two versions which can be downloaded on Cisco networking Academy (netacad) platform : "Cisco Packet Tracer Student" and "Cisco Packet Tracer Instructor".

Packet Tracer 6.2 fixes several bugs reported in previous versions and includes a new Cisco 819 router, a wired sniffer with repeater functionnality and some new 3G/4G devices (3G/4G cell tower and central office (CO) server) as well as 3G/4G support for end devices (phone, tablet, server, ...)

Packet Tracer 6.2 is fully supported on Windows 7 and Windows 8 or 8.1. Support for Windows XP has been stopped by Cisco in this new version.

 

Packet Tracer 6.2 new features :

HTTP server (server device) :

  • Javascript and CSS support
  • HTTP and FTP linked file management support
  • Externel file import inside Packet Tracer HTTP server

New devices :

  • Cisco 819 Integrated Service Router with wlan access point capability and 3G/4G connectivity
  • 3G/4G telephony cell tower
  • 3G/4G central office (CO) server with coaxial connectivity with up to 8 cell towers
  • Wired sniffer with repeater functionnality

 

 

Cisco 819 Integrated Service Router

Cisco 819 ISR router

This new ISR router features 3G/4G WAN connectivity as well as an internal wireless access point. The router can be connected to the simulated mobile operator infrastructure (cell tower, ...) using the following IOS command :

cellular 0 gsm profile create "profile number" "apn" "authentication" "username" "password" ipv4
Authentication : PAP or CHAP
Username : Username provided by the mobile service provider for 3G/4G connectivity.
Password : Password provided by the mobile service provider for 3G/4G connectivity.

Mobile connectivity can be used to provide backup WAN connectivity for a branch office. In this case, the cellular interface connected to the Internet is isolated in a separate VRF and an IPSEC tunnel is established between the branch office and the central location.

Sniffer device

A sniffer device has been added to Packet Tracer 6.2. This traffic analysis device which can be installed inline logs all the selected traffic on a network segment. An event list filter help the user to select the network protocols to record to avoid buffering unwanted traffic. This device records traffic in "RealTime" Packet Tracer mode and is better than Packet Tracer "Simulation" mode to understand packet flow on a specific segment. Packet Tracer "Simulation" has to be prefered to monitor a specific trafic flow (ex : voip, dhcp, ...) on the entire network

Known bugs

ASA 5505 firewall bugs

A major CLI bug affects Packet Tracer 6.2 ipsec configuration. The crypto ipsec ikev1 transform-set --name-- esp-aes-256 esp-sha-hmac is not correctly written in the running-config and as such not saved when closing the lab pkt file. The command appears as below in the running-config :

crypto ipsec ikev1 transform-set --name-- esp-aes 256 esp-sha-hmac

Consequence : The following two lines are not saved in a pkt lab simulating IPSEC tunnels between ASA 5505 firewalls

crypto ipsec ikev1 transform-set  --transform-set-name--  esp-aes-256 esp-sha-hmac

crypto map --map-name-- 1 set ikev1 transform-set --transform-set-name--

Cisco Packet Tracer 7.3 has been released ! Current build is Packet Tracer 7.3.0.0838. Have a look at Cisco Packet Tracer 7.3 new features

General improvements in Cisco Packet Tracer 6.1.1

Cisco Packet Tracer 6.1 (version 6.1.0.0120) has been available on netacad since July 2014 for Cisco Networking Academy members. A newer verion, Packet Tracer 6.1.1 has been released at the end of august. This is a minor release correcting bugs found in the previous 6.1.0.0120 version. Packet Tracer 6.1.1 includes the following new or improved features :

Server (end-device) new services / applications :

  • New service tab (config and service tabs mixed in previous versions)
  • Netflow collector as a new server desktop application
  • AAA accounting desktop application
  • IPv4 and IPv6 firewalls moved from service to desktop application
  • DHCP service for IPv6

 

IPv6 Routing protocols enhancements :

  • OSPFv3 enhancements : distance command, "ipv6 ospf neighbor" interface subcommand, ....
  • EIGRPv6 over Frame Relay
  • EIGRPv6 debug and authentication commands
  • RIPng distance command update
  • RIPng "default-information originate" command

 

DHCP new features :

  • DHCP snooping
  • APIPA adressng in case of DHCP lookup failure
  • DHCPv6 commands in IOS15

 

Switches :

  • IOS 15 support for Catalyst 2960 switch. The IOS 15 image has to be downloaded by TFTP or FTP from a server device to be available on a switch.

 

Simulation / Activity Wizard:

  • Expanded buffer for PDUs and filters based on IPv4 or IPv6 traffic in simulation mode
  • Improved scripting and variable management Activity Wizard

 

Port channel support has also been improved in Packet Tracer 6.1.1 with layer 3 etherchannel support on ISR routers.

Packet Tracer 6.1.1 is fully supported on Windows 7 and Windows 8 or 8.1. Support for Windows Vista has been stopped by Cisco in this new version.

 

New Hardware in Cisco Packet Tracer 6.1.1

Cisco Packet Tracer 6.1.1 includes a major capacity improvement with the introduction of  a new Security device class including an ASA 5505 firewall. By default, the Eth0/0 interface is configured in the outside vlan (vlan 2) and the Eth0/1 to Eth0/7 interfaces in the inside vlan (vlan 1).

 

Features & limitations compared to the real ASA 5505:

New vlans can be created using the config tab or the cli command "interface vlan X". However, the licence included in the ASA doesn't allow configuring more than two vlan with nameif (This license does not allow configuring more than 2 interfaces with nameif and without a "no forward" command on this interface or on 1 interface(s) with nameif already configured).

Another limitation is on the physical interfaces which can only be configured in access mode. The command "switchport mode trunk" documented in the ASA configuration guide has not been implemented on the simulated ASA 5505 in Packet Tracer 6.1 .

 

IPSEC tunnels and clientless SSL VPN are supported on ASA 5505 but VTI interfaces or GRE tunnels are not available on this firewall. GRE tunnels have to be terminated on an inside ISR edge router.

Netflow

Netflow is a network analysis protocol that was initially created by Cisco to give the ability to collect network traffic as it flows through a router interface. The data processed by Netflow collectors provides the network administrator with detailled traffic informations such as the source and destination of the traffic, class of service, .... Netflow version 9 was standardized in 2008 as IPFIX by the IETF organization.

The following Netflow components are available in Packet Tracer 6.1.1 :

  • Netflow version 9 on Cisco ISR routers. This feature is not available on Layer 3 switches.
  • A netflow collector software on PC, laptop and server devices.
