resume-offset

The default size of the ingress buffer is 45KB. The default buffer limit at which the

port sends the pause to peer and recommences the sending of packets to the peer

is 10KB. The default threshold weight of the shared buffer space is 10.

DCB-BUFFER-THRESHOLD mode

You must apply this buffer policy at the interface level for the attributes to be

applicable with the DCB input policy.

For each QoS policy buffer, you can specify the shared buffer threshold limit, the

ingress buffer size, buffer limit for pausing the acceptance of packets, and the

Data Center Bridging (DCB)

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

from 0 to 7787. The default is 45KB.

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 from 0 to 7787. The default is

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 from 1 to 7787. The default is

Buffer shared threshold weight

Weightage of the priorities on the shared buffer size in the

system. Enter a number in the range from 0 to 9. The default

shared threshold weight is 10.
