Managing automatic POD port assignments

The Dynamic POD feature is only used on the 100 GbE ports of the SLX 9540 platform . With the Dynamic POD feature, you can use the base port set plus the number of additional ports you purchased. All ports that do not receive a POD assignment and are trying to come online will go offline. The show ip interface brief and show interface ethernet slot/port commands display the reason for the port-disabled status as related to POD licensing.

The Dynamic POD mechanism detects the ports that have active links, and makes assignments based on the remaining pool of vacancies:

• If the count of assigned ports is below the number of ports in the combined Base allowance plus the capacity provided by the purchased POD set, additional dynamic assignments can be made at a later time as new links are established. If a port comes online, that port can get assigned if you still have vacancies in your POD set.
• If the number of detected active links is greater than the Base allowance plus the number of ports in the purchased POD set, port assignments are made in the order in which the ports come online until the purchased limit is reached. Because the time it takes for each port to come online varies, the order in which ports are assigned to a given POD set cannot be guaranteed.

If the given assignment order does not align with your intended use of the ports, you can make adjustments using the dpod slot/port reserve or the dpod slot/port release configuration commands. Refer to Overriding Dynamic POD assignments for more information.
