Page 54: Allocation values, Buffer

The port-region variable is the device number on which the user-configurable buffer profile is applied.
The user-profile-name variable is the name of the user-configured profile.
Buffer and descriptor maximum and default allocation values
This section lists the maximum and default buffers and descriptors values of a port and its queues on
each hardware platform. The following tables are included:
•
describes FCX devices.
•
describes ICX 6610 devices.

NOTE
Values in the following tables are for software traffic classes (TCs) or QoS priority (qosp) levels.
