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.

VLAN management is quite different on ISR routers than on Catalyst switches. VLAN can be used as 802.1q subinterfaces for routed interfaces or with a switch-like configuration on Ethernet Switch Modules (HWIC-4ESW for example)
Subinterface configuration (routed interfaces)
Layer 3 router interfaces cannot be configured in switch mode using "switchport" command on a Cisco ISR router. However, 802.1q trunks interconnexion is supported on these interfaces using the subinterface feature.
Virtual layer 3 interfaces are bound to the physical port using the interface <interface name>.<inderface id> command, <interface id> beeing the subinterface ID. For better configuration readability, the <interface id> is usually configured with the <vlan id> value. The encapsulation dot1Q <vlan id> maps the trafic flowing with the 802.1q vlan id (tagged) to the subinterface.
In the example below, FastEthernet0/0.20 is a subinterface bound to the FastEthernet0/0 physical interface. FastEthernet 0/0.20 is configured to process trafic flowing on vlan 20 in the 802.1q trunk connected to the FastEthernet 0/0 physical router interface.
encapsulation dot1Q 20
ip address 10.20.10.1 255.255.255.0
encapsulation dot1Q 30
ip address 10.30.10.1 255.255.255.0
VLAN database (ESW module)
If an EtherSwitch Service Module (HWIC-4ESW for example) has been installed on the ISR router, VLAN for that module can be configured using the vlan database in Packet Tracer 7.2. Port membership to the vlan is configured in the same way than on a Catalyst switch using the "switchport access vlan <vid>" commmand.
