If you configure buffers at the port or queue level (using qd commands or buffer profiles), the buffer
sharing level automatically changes to 1. You can change it manually.

ICX 6610 buffer sharing levels

The ICX 6610 buffer sharing level configures the shared buffers on the device. The ICX 6610 shared
buffers are divided into pools. Each of the following pools defines the buffer allocation for a set of
traffic class (TC) queues:

• Pool 0 contains TCs 0 and 1.
• Pool 1 contains TCs 2, 3, and 4.
• Pool 2 contains TCs 5 and 6.
• Pool 3 contains TC 7.

For example, the buffers allocated to Pool 0 are shared between TCs 0 and 1. The following table
defines the ICX 6610 buffer sharing level settings. Note that only the values of Pool 0 change. For
information about configuring buffer sharing, refer to
