What‘s new in Cisco Packet Tracer 7.2 & Packet Tracer 7.2.1 ?

Packet Tracer 7.2 & 7.2.1 main new feature is the new theme of the user interface designed to give a better network simulation experience.

Packet Tracer 7.2 & 7.2.1 workspace improvements :

• New themes
• Align workspace objects
• Ability to deploy device to specific rack
• Assessibility update
• Ability to name a rack

Protocol and software improvements :

• Protocol improvements (see below)

New devices in Packet Tracer 7.2 & 7.2.1:

• ASA 5506-X firewall (FirePOWER features not supported) (see Lab 18 - DMZ configuration with ASA 5506-X )
• Meraki security appliance
• Meraki server (for Meraki security appliance centralized configuration, emulating Cisco Meraki dashboard)
• Home router with advanced wireless capabilities (2.4G, 5G, beamforming, wireless bridge, ...)

Meraki server and security appliance are the first two devices emulating Cisco Meraki cloud managed network equipment.

A valid Cisco Netacad account is needed to use Packet Tracer 7.2 . Netacad login is required once after every PC reboot.

Protocol improvements :

• HSRP configurationis now supported on Cisco ISR 2911 sub-interfaces (example : int gi0/0.10)
• debug ip packet command is now supported in Packet Tracer 7.2
• debug ip eigrp command is now supported in Packet Tracer 7.2
• DHCPv6 client is now supported on ISR1941 router interfaces

The following improvements are expected in a future Packet Tracer release (ie : not included in Packet Tracer 7.2) :

• VTP v3 support is expected on Catalyst 3650 (VTP Version capable : 1 to 3 but no option to move to vtp v3 using vtp version)
• Private vlans and vlan-acl support is expected on IOS 15 in a future Packet Tracer release
• ip rip authentication command is expected in a future Packet Tracer release

New devices in Cisco Packet Tracer 7.2 & Packet Tracer 7.2.1

Cisco ASA 5506-X firewall

Cisco ASA 5506 is an upgrade from legacy Cisco ASA5505 which have been end of sale since August 2017. It incorporates the Cisco FirePOWER IPS technology, provides next-generation Intrusion Prevention (NGIPS), Application Visibility and Control (AVC), Advanced Malware Protection (AMP) and URL Filtering.

ASA 5506 is available in three models, but only ASA 5506X is emulated in Cisco Packet Tracer 7.2 :

• Desktop model 5506-X (emulated in Packet Tracer 7.2),
• Integrated wireless access point model 5506W-X
• Ruggedized model 5506H-X for industrial control systems and critical infrastructure environment.

ASA 5506-X is emulated with software version 9.6(1) and Security Plus license. Cisco FirePOWER features are not emulated in Packet Tracer.

The following features are licenced for this ASA 5506 platform in Packet Tracer 7.2 :

Meraki security appliance

A simplified version of the Cisco Meraki Security Appliance, model MX65W, has been added in Packet Tracer 7.2.

Meraki Security Appliance is a cloud managed Unified Threat Management (UTM) devices with Software Defined Wide Area Networking (SD-WAN) and wireless capabilities included.

Basic networking configuration can be achived via an HTTP session from a PC directly connected to the security appliance through the URL http://setup.meraki.com (login is the serial number of the appliance displayed on the config tab, no password). However, wireless and security functions have to be configured through the Meraki Server via the URL https://dashboard.meraki.com after having linked the Security Appliance to the Meraki Server.

Supported features of the MX65W are :

• Addressing & VLANs
• DHCP server
• Wireless Access Point. Supported security modes are Open, WEP, WPA2 PSK, and WPA2 Enterprise.
• Firewall (outbound rules only)
• PPPoE internet connection

Home Router

Home Router has been added in Packet Tracer 7.2 to emulate Linksys WRT120N Wireless-N Home Router. This home router features advanced wireless capabilities:

• Wireless 2.4G and 5G mode
• Wireless Media Bridge
• Wireless Beamforming
• Per Wireless interface Mac address filtering
• WEP, WPA-PSK, WPA-Enterprise, WPA2-PSK, WPA2-Enterprise with radius server and AES / TKIP encryption

New protocol support in Cisco Packet Tracer 7.2

Wired 802.1x (dot1x) device authentication

Wired 802.1x device authentication has been added to Catalyst switches emulated in Packet Tracer 7.2 . This feature is available with the following limitations :

• dot1x commands only supported with IOS 15. Update of the switch image is required (IOS 15 images available on the server device) before configuring 802.1x authentication.
• EAP-MD5 is the only EAP protocol supported.

802.1x configuration form has been added to end devices IP configuration utility.

PPPoE authentication

PPPOE support has been added to ISR routers, Meraki Security Appliance, and end devices (PC, servers) in Packet Tracer 7.2.

PAP and CHAP authentication is supported in Packet Tracer 7.2

PPPoE is a protocol widely used by Internet Service Providers to provide high speed internet services which can use the same authentication server for both PPP and PPPoE sessions, resulting in a cost savings. It expands the capability of PPP by allowing a virtual point to point connection over a multipoint Ethernet network architecture. PPPoE uses the same methods of compression, authentication, and encryption than PPP.

Real HTTP server and real websocket

Packet Tracer 7.2 IoT programming features now include a realHttpServer capability which starts an HTTP server accessible from outside the Packet Tracer environment. The HTTP server can be accessed from a web browser installed on the PC running Packet Tracer. In order for this to work correctly one may need to enable the [?] Enable External Network Access from Device Scripts from the Miscellaneous tab of the Options/Preferences dialog box.

 Packet Tracer 7.2 asks for user permission before starting the web server and listening on port 8765.

Output the C:\Program Files\Cisco Packet Tracer 7.2\saves\7.2\IoT\real-websocket.html test page provided to test the new real websocket capability.

DHCPv6 client on ISR1941 router
DHCP v6 client is now supported on ISR1941 router interface. Gigabit Ethernet interface IPv6 address can now be dynamically obtained by DHCP with the "ipv6 address dhcp" IOS command. ISR1941 can also act as  DHCPv6 server with the "ipv6 dhcp pool <pool name>" command.
