This is an older end of sale series but we are still using and reusing them in some parts of the network. I will be terminating a 1 Gigabit internet link on a 2921 router.
Is there a performance on demand license that I need to buy for this? Like we do for the newer 4331 series routers. I was looking for one but i wasn't able to find what it is called. Does it even exists and is the throughput limited in anyway?
