buffer size. If the buffer size and DCB buffer threshold settings are applied on one
or more ports, a validation is performed to determine whether following condition
is satisfied: If the preceding condition is not satisfied by the shared PFC buffer size
value, the configuration is not saved and a system logging message is generated as
follows:
Shared-pfc-buffer-size <= (Total-pfc-buffer-size - Σpfc priority <> buffer-size on
each port, priority).
Dell(conf)#dcb pfc-shared-buffer-size 2000
%ERROR: pfc shared buffer size configured cannot accommodate
existing buffer requirement in the system.
Example Dell(conf)#dcb pfc-shared-buffer-size 5000
dcb-buffer-threshold Configure the profile name for the DCB buffer threshold. This utility is supported on the S4810, S4820T,
and S6000 platforms.
S6000
Syntax dcb buffer—threshold profile-name

Usage
Information
When you enter the profile name, you enter the DCB buffer threshold
configuration mode. 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.
