Throughput license installation in ASR 1002-x

There is no need to install the license on the router as cisco ASR 1002-x supports RTU(Right to use) method where cisco trust the customer.

I have installed L-FLSA1-2X-5-10G= on the router 1002-x.

Below is the command to configure new throughput level but it requires the reboot to activate.

(config)#platform hardware throughput level 10000000

PLEASE READ THE FOLLOWING TERMS CAREFULLY. INSTALLING THE LICENSE OR LICENSE KEY PROVIDED FOR ANY CISCO PRODUCT FEATURE OR USING SUCH PRODUCT FEATURE CONSTITUTES YOUR FULL ACCEPTANCE OF THE FOLLOWING TERMS.

YOU MUST NOT PROCEED FURTHER IF YOU ARE NOT WILLING TO BE BOUND BY ALL THE TERMS SET FORTH HEREIN. Use of this product feature requires an additional license from Cisco, together with an additional payment. You may use this product feature on an evaluation basis, without payment to Cisco, for 60 days. Your use of the product, including during the 60 day evaluation period, is subject to the Cisco end user license agreement http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.htmlOUTPUT SHORTENED

Activation of the software command line interface will be evidence of your acceptance of this agreement.

ACCEPT? (yes/[no]): yes

ASR# write memory

Building configuration…

[OK]

ASR##reload

Proceed with reload? [confirm]

After reboot, license remains as EvalRTU license for 60 days and then it changes automatically to Right-To-Use License

You can also use below command to move the license directly to permanent status instead of waiting for 60days.

ASR # license right-to-use move throughput

Use below commands to verify the throughput

ASR # show platform hardware throughput level

ASR# show license feature | include Feature|throughput
