My Lab Notes

Download the VMWare appliance here:
http://www.juniper.net/support/downloads/?p=firefly#sw

You will find the latest version v12.1X47-D20, file size is around 230 Mb.
Note: You will need an authorized login account to download the appliance. Google v12.1X47-D20 it is also available on some file sharing websites in case you don't have one.

Download and extract with 7zip or winrar. We only need one file.

Run Oracle VM Manager and add create a new Virtual Machine. Click "Next"

Set the memory size to 1 GB or 2 GB if you are planning to run and configure a lot of security features and you have lots of available physical memory on board.

Apply the following settings:

Under the Motherboard Tab, check the Extended Features.

Under the processor tab, allocate 2 CPU and enable PAE/NX

Disable Audio, Enable Serial Port

Enable Network Adapter (not connect) 4 is currently available (8 is supported)

Click "OK" to close the Settings. You can close the VM Virtual box and create a notepad and type the following commands. Copy and paste it on the command prompt and then run VM Virtual Box to see the changes.

Configure GNS3 Preferences under Virtual Box and load the cloned vSRX virtual machine.

Create a simple topology and turn on the devices.

Once the vSRX client is up, access it via console and login as root with no password and you're ready to play with Juniper OS.

An alternative option of updating my lab switches using a .bin IOS image.
I prefer this method as using the tar via archive download-sw takes time.

(connect any port on the switch to my home router)
Switch(config)#int vlan 1
Switch(config-if)#ip address dhcp
Switch(config-if)#no shut
Switch(config-if)#
*Mar 1 00:02:51.370: %LINK-3-UPDOWN: Interface Vlan1, changed state to up
*Mar 1 00:02:51.379: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to up
Switch(config-if)#
*Mar 1 00:02:57.511: %DHCP-6-ADDRESS_ASSIGN: Interface Vlan1 assigned DHCP address 192.168.254.14, mask 255.255.255.0, hostname Switch

Old IOS backup (optional)
The .bin file i have to backup is in a directory

Switch#dir flash:
Directory of flash:/

    2 drwx        3072 Apr 10 1993 18:14:10 +00:00 crashinfo_ext
   41 -rwx        1920   Mar 1 1993 00:01:22 +00:00 private-config.text
   42 drwx         512   Mar 1 1993 00:08:39 +00:00 c2960-lanlitek9-mz.122-50.SE2

598 drwx       18432   Mar 1 1993 00:00:09 +00:00 crashinfo

To get the complete path of the image file:

Switch#dir flash://c2960-lanlitek9-mz.122-50.SE2
Directory of flash:/c2960-lanlitek9-mz.122-50.SE2/

   43 drwx        5632   Mar 1 1993 00:04:39 +00:00 html
595 -rwx     7353624   Mar 1 1993 00:06:09 +00:00 c2960-lanlitek9-mz.122-50.SE2.bin
596 -rwx         426   Mar 1 1993 00:08:39 +00:00 info

This is the complete command:
Switch#copy flash:/c2960-lanlitek9-mz.122-50.SE2/c2960-lanlitek9-mz.122-50.SE2.bin tftp:

Address or name of remote host []? 192.168.254.5

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
7353624 bytes copied in 19.738 secs (372562 bytes/sec)

Then delete the directory containing the old image to free some space:
Switch#delete /force /recursive flash:/c2960-lanlitek9-mz.122-50.SE2

Download the recommended update from TFTP server:

Switch#copy tftp:/c2960-lanlitek9-mz.122-55.SE10.bin flash:
Address or name of remote host []? 192.168.254.5
Destination filename [c2960-lanlitek9-mz.122-55.SE10.bin]?

8107679 bytes copied in 119.412 secs (67897 bytes/sec)

Note: Adjust the TFTP server timeout to avoid timeout errors and out of sequence packets.

Loading /c2960-lanlitek9-mz.122-55.SE10.bin from 192.168.254.5 (via Vlan1): !OOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOOO!OOOOOO!OOOOOOOO!OOOOOOOOOOOO!OOOOOOOOOOOOOOOO... [timed out]

And last step, modify the boot parameters as i have deleted the old IOS:
Note that the current boot path is still pointing to the deleted image.
Switch#show boot
BOOT path-list      : flash:/c2960-lanlitek9-mz.122-50.SE2/c2960-lanlitek9-mz.122-50.SE2.bin

The new Image, recently loaded.
Switch#dir flash:

Reload to boot the new IOS:

Done, this procedures works for 3750 and 3560 switches too.
