Packet Tracer is a free application by cisco and can be downloaded under netacad.com website
( Click the blow link ). Recently cisco has supported Packet Tracer to Mac computers too.

But we all knew we are moving to IPv6 world and hence we need to run the IPv6 most of the time.
Unfortunately, packet Tracer doesn't support IPv6 on Switch by default. I am going to do the step-by-step configuration to enable IPv6 on CISCO 2960 switch.
Let's do it.
First of all we need to setup a small network to upgrader the IOS version, We need IOS version 150-2 to enable IPv6
we need a switch and a server to do this upgrade.
Assign IPs to both server and switch ( int vlan 1)
TFTP server : 192.168.1.1
Switch : 192.168.1.2
once the IPs are assigned we must be able to ping each other.
Then make sure the server has got TFTP and it has IOS version 15 as well.
Now lets go ahead and start the upgrade
in switch enter the following commands.
Switch#copy tftp: flash:
Address or name of remote host []? 192.168.1.1
Source filename []? c2960-lanbasek9-mz.150-2.SE4.bin
Destination filename [c2960-lanbasek9-mz.150-2.SE4.bin]?
once you confirmed you will see the following
[OK - 4670455 bytes] 4670455 bytes copied in 0.199 secs (1886872 bytes/sec)
Alright now we have got the 150-2 version ios file to flash drive.
reload the switch and change the boot file using the following command
Switch(config)#boot system c2960-lanbasek9-mz.150-2.SE4.bin
Again reload the device to load 150.2 ios image.
Now you could see
Loading "flash:/c2960-lanbasek9-mz.150-2.SE4.bin"...
##############################
This means the device is now loading the IOS version 15.
once its done with booting we need to enable the IPv6 Dual-stack configuration in the switch
use the following command to enable the dual-stack configuration
Switch(config)#sdm prefer dual-ipv4-and-ipv6 default
That's all we are done and we should be able to use the IPv6 configuration now, this will take place once we reload the device
so reload one more time, we can see the IPv6 commands enabled.
Thanks,
