•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.

Only the queues for which the buffer cell consumption is not zero are displayed. If an egress buffer is not present on any of the queues on port 5, the following sample output is displayed:
