Buer management
OS10 devices distribute the total available buer resources into two buer pools at ingress direction and three buer pools at egress
direction of all the physical ports.
All ports in a system are allocated a certain amount of buers from corresponding pools, based on the conguration state of each priority-
group or queue. The remaining buers in the pool are shared across all similarly congured ports.
The following buer pools are available:
• Ingress buer pools:
– Lossy pool (default)
– Lossless pool (PFC)
• Egress buer pools:
– Lossy pool (default)
– Lossless pool (PFC)
– CPU pool (CPU control trac)
For example, when all ports are allocated reserved buers from the lossy (default) pool, the remaining buers in the lossy pool are shared
across all ports, except the CPU port.
When you enable priority ow control (PFC) on the ports, all the PFC enabled queues and priority-groups use the buers from the lossless
pool.
OS10 dedicates a separate buer pool for CPU trac. All default reserved buers for CPU port queues are from the CPU pool, and the
remaining buers are shared across all CPU queues. You can modify the buer settings of CPU queues.
OS10 allows conguration of buers per priority-group and queue for each port.
