Usage
Information
The following information is displayed depending on whether the historical snapshot of buffer statistics is
needed for all ports, per-port per-queue, or a priority group.
● All – Displays all resources on ingress and egress for each of the port, queue.
● Port-Queue ucast/mcast – Displays the total unicast/multicast buffer usage on per-port per-queue
basis. For CPU port, counters for queues 0 – 11 are displayed and no differentiation is made between
unicast and multicast queues.
● Port- Priority-Group – Displays the shared space counters usage, head-room space counters per
ingress port on per-priority- group granularity.
When the buffer-stats-snapshot is disabled, an informational message is dispayed to this effect when you
attempt to view the buffer statistics tracking resource information without polling details and historical
snapshots.
