Brocade FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide - Manual (Page 54)

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:
• Table 8 describes FCX devices.
• Table 9 describes ICX 6610 devices.
• Table 10 describes ICX 6430 devices.
• Table 11 describes ICX 6450 devices.
NOTE
Values in the following tables are for software traffic classes (TCs) or QoS priority (qosp) levels.
Port buffers and descriptors values on FCX devices TABLE 8
