Cisco License Generator - fasrct For those that have been using Cisco IOS 12 forever, you may not have realized that Cisco has begun rolling out IOS 15. Although there are a lot of that are being introduced, IOS 15 introduces a new licensing scheme that may throw old users for a loop. We were unable to find the support information for the product IOS Please refine your query in the Search box above or by using the following suggestions: Verify the correct spelling of the product name; Include both the product name and number in your search. Examples: Catalyst 6500 Series Switches; 7600 Series Routers.

In continuation of my Cisco IOS XR posts, this one will be on how to install license files on the Cisco IOS XR code train.
The following L3VPN licenses are available for Cisco IOS XR:

As of Cisco IOS Release 12.4 (11)T, peer public RSA key modulus values up to 4096 bits are automatically supported. The largest private RSA key modulus is 4096 bits. Therefore, the largest RSA private key a router may generate or import is 4096 bits. However, RFC 2409 restricts the private key size to 2048 bits or less for RSA encryption. Cisco installs license key (s) for software specified at time of initial router purchase. On each shipped device IP Base software activation key is installed by default. Additional keys are installed by manufacturing depending on the customer order. The details of each technology package license can be found in the table below. If you’re in need of a license key for, you’re in luck. A new license generator, iougen, has popped up on Github in the last day or two. From the README file: iougen is a python module/cli script that can be ran to generate IOU license keys. IOU stands for IOS on Unix and is a full IOS environment that can run as a Unix process.

So, lets get on with this and the ever loving Cisco licensing – well, not just Cisco but all vendors have some type of licensing. With the IOS XR in this case, we need a license to run VRF interfaces on our line cards. In order to request a license, you need to have a PAK key that you purchase, once you have that you will need to gather some information to request the license key.
From the command prompt, enter the admin mode
RP/0/RSP0/CPU0:R2#admin
Tue Apr 17 01:34:35.939 UTC
From there, enter the command show license udi
RP/0/RSP0/CPU0:R2(admin)#show license udi
Tue Apr 17 01:34:38.950 UTC
Local Chassis UDI Information:
PID : ASR-9010-AC
S/N : FOXXXXXAAAA
Operation ID: 1
RP/0/RSP0/CPU0:R2(admin)#
This information will be used on the Cisco License site – www.cisco.com/go/license (CCO Account required). Once you have submitted the PAK request, Licensing@cisco.com will send you the license file as an attachment within a few hours.
Once you have received the license file, you will need to copy it to the router via TFTP or some other method. The license file will also include the instructions to add it, and I have included them here as well. The license file we will be installing is called foo.lic and is on TFTP server 1.1.1.2
RP/0/RSP0/CPU0:R1#copy tftp: compactflash:
Wed Apr 11 05:23:23.259 UTC
Address or name of remote host []?1.1.1.2
Source filename [/tftp:]?foo.lic
Destination filename [compactflash:]? [just hit enter]
Accessing tftp://1.1.1.2/foo.lic
C

RP/0/RSP0/CPU0:R1#admin
Next we can use the license add command from Admin mode
RP/0/1/CPU0:CRS#
RP/0/1/CPU0:CRS(admin)#license add compactflash:/foo.lic
RP/0/1/CPU0:Mar 16 16:01:37.077 : licmgr[252]: %LICENSE-LICMGR-6-LOAD_LICENSE_FILE_OK : All licenses from license file compactflash:/foo.lic added successfully
License command “license add compactflash:/foo.lic sdr Owner” completed successfully.
RP/0/1/CPU0:CRS(admin)#
Now we need to see if is has been added via the show license command
RP/0/1/CPU0:CRS(admin)#show license

FeatureID: foo (Slot based, Permanent)
Available for use 1
Allocated to location 0
Active 0
Pool: Owner
Status: Available 1 Operational: 0
Pool: sdr1
Status: Available 0 Operational: 0
Once the license has been successfully added, we now need to assign it to a line card slot. Again, this is done from Admin config mode
RP/0/RSP0/CPU0:R1(admin)#config
To assign the license, the command is license (License) location (LocationID). In our case, we are going to apply A9K-iVRF-LIC. The question mark will show you what location are available for this license.
RP/0/RSP0/CPU0:R1(admin-config)#license A9K-iVRF-LIC location ?
0/0/CPU0 Fully qualified location specification
0/1/CPU0 Fully qualified location specification
0/RSP0/CPU0 Fully qualified location specification
WORD Fully qualified location specification
all all locations
Now we can apply the licenses that we have to 0/0 and 0/1:
RP/0/RSP0/CPU0:R1(admin-config)#license A9K-iVRF-LIC location 0/0/CPU0
RP/0/RSP0/CPU0:R1(admin-config)#license A9K-iVRF-LIC location 0/1/CPU0
RP/0/RSP0/CPU0:R1(admin-config)#commit
Thu Apr 19 03:13:44.883 UTC
RP/0/RSP0/CPU0:R1(admin-config)#exit
RP/0/RSP0/CPU0:R1(admin)#exit
Once installed, we should check
RP/0/RSP0/CPU0:R1#sh license
Thu Apr 19 03:13:51.432 UTC
FeatureID: A9K-iVRF-LIC (Slot based, Permanent)
Total licenses 2

Allocated to location 0
Active 2

Store index 1

Total licenses in pool: 2

There they are, assigned to 0/1 and 0/0 as requested.
