buffer packets interface

This command sets packet limits per-port/per-queue on ports 1 – 48 and the stack port on the S50, ports
1 – 52 and the stack port on the S50V, and ports 1 – 28 on the S25P.
Syntax [no] buffer packets interface { unit/slot/port | system-uplink | system-downlink}
Queue-0_buffer Queue-1_buffer Queue-2_buffer Queue-3_buffer Queue-4_buffer
Queue-5_buffer Queue-6_buffer
To return buffers to their default values, use the no buffer packets interface unit/slot/port, no
buffer packets system-uplink, or no buffer packets system-downlink command syntax,
depending on the target port.

Introduced
Enter the port that you want to configure, in unit/slot/port format.
The possible ports vary by platform:
•
•
•
For the S50 and S50V only, enter the keyword
the stack ports of all stack members.
For the S50 only, enter the keyword
output from the switch fabric buffer.
For each of the seven queues, in sequence, enter a number indicating its desired
buffer size, in 1KB increments (for example, 100 for 100KB).
All S50, S50V, and S25P queues have a 2047 packet limit. The total number of
Queue-6_buffer
packets cannot exceed 2047 per port. It is possible to reduce the packet limit of
Queue 7 to 0 by allocating the total of 2047 packets to the other queues.
Introduced
Verify that the configured buffer allocations meet the hardware requirements.
Set dynamic buffer sizes per port for 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 ASICs controlling the optional 10GB
ports 49 and 50 on the S50 and the 10Gb ports on the S25P.
