Introduced on the MXL platform.
Usage
Information
Configure the maximum shared buffer available for PFC traffic. You can choose to
increase or decrease the shared buffer that is currently allocated in the system by
default. You must configure the shared buffer size to be less than the total PFC
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:
Shared-pfc-buffer-size <= (Total-pfc-buffer-size -
Σ
pfc priority <> buffer-size on
each port, priority).
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:
S4810-YU-MR-FTOS (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.
Syntax
dcb buffer—threshold
profile-name
Parameters
profile-name
Enter the name of the profile, which can be a string of up to
32 characters in length.

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.
