This is what happens when you make your switch customers buy software they don't need or want just to try to fill the sales figures. Also forcing customers to allow products to call home to the Cisco mother ship to verify licenses. Imagine your TOR switches suddenly deciding there's an error or Cisco getting their data mixed up and your switches now all of a sudden drop half their licensing ! Utter madness.
I used to be a bit of a Cisco fan but the last 5 years has been very difficult and I've had enough. Juniper it is now.
