Version Description
9.9(0.0) Introduced on the C9010.
9.7(0.0) Introduced on the S6000-ON.
9.3(0.0) Introduced on the S6000 platform.
Usage
Information
Configure the maximum buffer available for PFC traffic. You can choose to increase or decrease the
buffer size that is currently allocated in the system by default. However, if you modify the PFC buffer size
to be lower than the previously configured PFC buffer size, the system determines whether this reduction
in size is valid without disrupting the existing configuration. In such a scenario, you must disable and re-
enable DCB. For example, if you modify the total buffer size to be 4000 KB from the previous size of
5000 KB, an error message is displayed that this reduction cannot be performed owing to existing system
configuration because of queues that are being currently processed.
