After you disable BST, be sure to clear the counter using the clear qos statistics type buffer-statistics-tracking
command.
Port to port-pipe and MMU mapping
A port pipe handles network traffic to and from a set of front-end I/O ports. On the Z9100–ON, Z9264F–ON, and MX9116n platforms,
interfaces are shared across port pipes and port pipes are shared across Memory Management Units (MMUs).
As interfaces span port pipes, Dell EMC Networking recommends using interfaces from same port pipes for both ingress and egress for
optimal performance. To find the port to port-pipe and MMU mapping, use the
show qos port-map details command.
Z9100–ON output example:
OS10# show qos port-map details
