Capacity on Demand and Dynamic Ports on Demand overview

Capacity on Demand (COD) and Dynamic Ports on Demand (POD) provides a flexible mechanism for allocating port licenses that you can purchase to extend the base functionality of the SLX 9540 switches. The additional ports can be enabled after you install the appropriate license keys. The Dynamic POD feature assigns port licenses based on your connectivity choices. Any port on the switch can claim a free assignment from the pool of available POD licenses. The COD licenses require explicit manual port assignment for non-base allowance ports before the port can be used at 10 GbE port speed.

Note

When adding a Dynamic POD license to a platform that does not support Dynamic POD, you will be allowed to add the license, but the license display will show that the Dynamic POD license is not supported on the platform.

In a Dynamic POD system, each port can be associated with one of two port sets:

• Base port set — Ports that can be enabled without any Port Upgrade license.
• Port Upgrade license port set — Ports that are assigned after all the Base port set have been used or assigned; these are associated with the existence of a Port Upgrade or Capacity on Demand license.

Note

The 100 GbE/40 GbE, 10 GbE, and 100 GbE Port Upgrade licenses are supported using a base port set plus the ports that are available as specified by the port capacity in the respective port upgrade. These licenses are supported only on the SLX 9540 switches.

Note

Licenses are based on the license ID and are not interchangeable between units.
