After you change the buffers, you should execute this command before rebooting the switch to verify
that the buffer allocations meet the hardware requirements.

This command sets buffer sizes per port and per queue for the ASICs controlling ports 1– 48 and the
stack port on the S50, and ports 1 – 52 and the stack port on the S50V.

Set buffer sizes per port and per queue for the optional 10Gb ports 49 and 50
on the S50 and the 10Gb ports on the S25P.

There is no system-uplink in the S25P.
Note:
For each of the seven queues, in sequence, enter a number indicating its
desired buffer size, in 1KB increments (for example, 100 for 100KB).
Each queue can be assigned from 0KB to any portion of the remaining total
memory. Queue 7 is unavailable for buffer carving, inheriting any of the
total buffer size not allocated.
The total buffer size varies by platform:
• S50: 988KB
• S50V: 2013KB
Memory measurement is the total combined dedicated and dynamic memory
per 12-port group.
