This read-only value reports the maximum number of interfaces per port that this registered application supports, from 1 to 2147483647, noting the actual limit could be further constrained by the port's own capacity. An admin compares this against a port's available interfaces to determine which constraint, the application's own limit or the port's hardware capacity, will bind first for a given deployment. For example, an application with a very high interface limit deployed on a port with only 4000 available interfaces would be capped by the port's capacity rather than the application's own registry limit.
