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 57-10. Display the
default buffer profile using the command
show buffer-profile stack-unit from EXEC Privilege mode, as shown
in Figure 57-9.

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 command no buffer-profile [fp | csf] 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 entering no buffer [fp-uplink |csf]
stack-unit port-set buffer-policy from CONFIGURATION mode and no buffer-policy from INTERFACE mode.
