Version Description
9.7(0.0) Introduced on the S6000-ON and Z9500.
9.6(0.0) Introduced on the S5000.
9.3(0.0) Introduced on the S4810, S4820T, and S6000 platforms.
Usage Information
Configure the maximum shared buffer available for PFC traffic. You can choose to increase or decrease the
shared buffer that is allocated in the system by default. Configure the shared buffer size less than the total PFC
buffer size. If the shared buffer size is more than the total PFC buffer size value, the configuration is not saved
and a system logging message is generated.
DellEMC(conf)#dcb pfc-shared-buffer-size 3000
% Error: Shared buffer size cannot be greater than the the available buffer
in the system
DellEMC(conf)#
Enter a smaller value for the shared buffer size or increase the total buffer size appropriately by using the dcb
pfc-total- buffer-size command.
Example
DellEMC(conf)#dcb pfc-shared-buffer-size 800
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.
Default None
