Dynamic buffer allocation for FCX, FWS, and ICX devices
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 105 describes FCX devices.
• Table 106 describes FWS devices.
• Table 107 describes ICX 6610 devices.
• Table 108 describes ICX 6430 devices.
• Table 109 describes ICX 6450 devices.
NOTE
Values in the following tables are for software traffic classes (TCs) or QoS priority (qosp) levels.
