Buffer management
OS10 devices distribute the total available buffer resources into two buffer pools at ingress direction and three buffer pools at
egress direction of all physical ports.
You can map a single traffic class or a group of traffic classes to a priority group. All ports in a system are allocated a certain
amount of buffers from corresponding pools based on the configuration state of each priority-group or queue. The remaining
buffers in the pool are shared across all similarly configured ports.
The following buffer pools are available:
● Ingress buffer pools:
○ Lossy pool (default)
○ Lossless pool
￭ PFC—For all platforms
￭ LLFC—For all platforms except the S4200-ON series switches
● Egress buffer pools:
○ Lossy pool (default)
○ Lossless pool
￭ PFC—For all platforms
￭ LLFC—For all platforms except the S4200-ON series switches
○ CPU pool (CPU control traffic)
The following terms are used in this section:
● Default buffer—By default, the system allocates a certain amount of default buffer to all the ports.
