size
Default The default size of the ingress buffer is 45 KB. The default buffer limit at which the
port sends the pause to peer and recommences the sending of packets to the peer
is 10 KB. The default threshold weight of the shared buffer space is 10.
Command DCB-BUFFER-THRESHOLD mode
Modes
Data Center Bridging (DCB)
Name of the QoS policy buffer that is applied to an interface
for this setting to be effective in conjunction with the DCB
input policy. You can specify the shared buffer threshold
limit, the ingress buffer size, buffer limit for pausing the
acceptance of packets, and the buffer offset limit for
resuming the acceptance of received packets. This method
of configuration enables different peer-provided and
administrative priorities to be set up because the intended
queue is directly configured instead of determining the
priority to queue mapping for local and remote parameters.
Specify the queue number to which the QoS policy buffer
parameters apply
Pause frames to be sent at the specified buffer limit levels
and pause packet settings
The packets for this queue must not be dropped
Enter a number in the range of 0 to 7 to denote the priority
to be allocated to the dynamic buffer control mechanism
Ingress buffer size
Size of the ingress buffer in KB. Enter a number in the range
of 0 to 7787. The default is 45 KB.
Buffer limit for pause frames to be sent
Buffer limit at which the port sends the pause to peer in KB.
Enter a number in the range of 0 to 7787. The default is 10
KB.
Buffer offset limit for resuming in KB
Buffer offset limit at which the port resumes the peer in KB.
Enter a number in the range of 1 to 7787. The default is 10
KB.
Buffer shared threshold weight
Weightage of the priorities on the shared buffer size in the
system. Enter a number in the range of 0 to 9. The default
shared threshold weight is 10.
