Configuring Queuing and Scheduling
switch# clear counters buffers
Max Cell Usage has been reset successfully
This example shows how to set a buffer utilization threshold for a specific module:
switch(config)# hardware profile buffer info port-threshold module 1 threshold 10
Port threshold changed successfully
Note
The buffer threshold feature is not enabled for ports if they have a no-drop class configured (PFC).
Note
The configured threshold buffer count is checked every 5 seconds against all the buffers used by that port
across all the queues of that port.
Note
You can configure the threshold percentage configuration for all modules or for a specific module, which is
applied to all ports. The default threshold value is 90% of the switch cell count of shared pool SP-0. This
configuration applies to both Ethernet (front panel) and internal (HG) ports.
Note
The buffer threshold feature is not supported for ACI capable device ports.
This example shows how to display the interface hardware mappings:
