Reference Guide

You cannot allocate more than the available memory for the dedicated buffers. If the system determines
that the sum of the configured dedicated buffers allocated to the queues is more than the total available
memory, the configuration is rejected, returning a syslog message similar to the following: 00:04:20:
%S50N:0 %DIFFSERV-2-DSA_DEVICE_BUFFER_UNAVAILABLE: Unable to allocate dedicated
buffers for stack-unit 0, port pipe 0, egress port 25 due to unavailability of
cells.
Dell Networking OS Behavior: When you remove a buffer-profile using the no buffer-profile [fp
| csf] command from CONFIGURATION mode, the buffer-profile name still appears in the output of
the
show buffer-profile [detail | summary] command. After a line card reset, the buffer profile
correctly returns to the default values, but the profile name remains. Remove it from the show buffer-
profile [detail | summary] command output by entering no buffer [fp-uplink |csf]
linecard port-set buffer-policy
from CONFIGURATION mode and no buffer-policy from
INTERFACE mode.
To display the allocations for any buffer profile, use the show commands.
To display the default buffer profile, use the show buffer-profile {summary | detail} command
from EXEC Privilege mode.
