ICX 6430 and ICX 6450 buffer sharing levels
The ICX 6430 and 6450 buffer sharing level configures the shared buffers on the device. Table 13 on
page 58 defines the FCX buffer sharing level settings. For information about configuring buffer sharing,
refer to
Configuring buffer sharing on FCX and ICX devices on page 57.
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.

Displaying buffer sharing information
To display information about buffer sharing, enter the show qd-share-level command. Following is an
example for an FCX device.
device# show qd-share-level
