• Port {id |all} queue ucast {id | all} - egress queue-level
snapshot for unicast packets only
• Port {id |all} queue mcast {id | all} - egress queue-level

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.
