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.
Display the allocations for any buffer profile using the
show commands in Figure 22-11. Display the
default buffer profile using the
show buffer-profile {summary | detail} command from EXEC Privilege mode
(Figure 22-10).

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
FTOS 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 show buffer-profile [detail |
summary]
.
After a stack unit is 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 using the no buffer
[fp-uplink |csf] stack-unit port-set buffer-policy
command from CONFIGURATION mode and the no
buffer-policy
command from INTERFACE mode.
