Avalanche: What can cause the Avalanche virtual to report a license error?
Reboot the license server and the VM to clear any issues and services that could be down.
When reserving a VM port make sure that you have set the port to
performance mode if you have a performance license or to
if you have a funcational license.
Check the license files are in the correct directories on the license server.
Copy the correct port license file (stv port) to the
of the license controller
Copy the feature license file to the
of the license controller.
The Avalanche Virtual and the License Server use the following TCP ports:
27000 - 27200 - The default ports used by the License Server for licensing
32768 - 61000 - Ephemeral ports used by the VM's Linux kernel to communicate with License Server
22 (ssh) - Used to SCP (secure copy) a file from the License Server to the VM
ICMP (VM periodically sends ICMP echo requests (Ping - ICMP message type 8) to the License Server to which it expects ICMP echo replies (ICMP message type 0))
Check firewall settings - it must be configured to allow the TCP sessions initiated outgoing and allow incoming on the ports listed above.
The Avalanche Virtual starts polling for license server for the feature license file after it's booted up.
NOTE: The Avalanche virtual takes about 1 minute to boot up. If it takes more than 10 minutes then it could not talk to the license server.
You may be able to reserve the VM port; however the Avalanche Commander reports a license error message when starting a test.
Check the lisense server is up and configured on the Avalanche VM. Check for any down service and reboot license server to bring service up.
Workaround if the Avalanche virtual is unable to poll the license server for license file. Manually upload the feature license:
1) Open the Spirent TestCenter application. Then connect to the VM ports.
2) Go to Tools | License Management and click
Then browse to select your feature license file.
