Howto License F5 BIG-IP LTM Appliance

Licensing a F5 BIG-IP® Local Traffic Manager™ (LTM) Virtual Edition (VE) is a multiple Step process. Let me run through it Step-by-Step.

These steps assumes following:-

1. You already know howto bring-up BIG-IP Virtual Appliance on your Hypervisor. I used KVM for this. 
2. You already have got the 'Registration Key' from F5 to activate this appliance.

Steps

1. Bring UP BIG-IP Virtual Appliance (Login: root Password: default)
2. Assign IP Address to it (Use 'config' command on BIG-IP to assign IP, Subnet and Default Gateway), so that it can be accessed via your Web Browser. 
3. This is how Non-Lisensed BIG-IP's prompt would look:-                                           [root@localhost:NO LICENSE:Standalone] config #
4. Open web interface to BIG-IP https://<mgmtIP> (Login: admin Password: admin)
5. Goto Setup-Utility->License and select Manual Method (Make sure you already have the "Registration Key" Typically 25 Digit Value), 
6. Enter the Registration Key, and press Next Tab
7. A Dossier would be generated by BIG-IP (based on your Registration Key). Copy this Dossier and Click on Step 2 which opens a new window and takes you to F5's Licencing Server ie. F5 Licencing Server
8. Enter the Dossier here, and click Next. 
9. Accept the Licencing Agreement here and Click Next
10. The next page has your License. Copy the whole License.
11. Now go back to the Local BIG-IP browser window form which you got the Dossier (see Step 6 above), and you would see "Step 3: License". Please paste the License here and click Next
12. If all goes fine, your device is Licensed and Activated....
13. Please Note the prompt would change now to:- (with 'Active' word)[root@localhost:Active:Standalone] config #
