Display the historical snapshot of buffer statistical values unit
Enter the keyword unit along with a port-pipe number, then
the keyword counters to display the counters on the selected
port-pipe. The range is 0 to 0.
port resource X Buffer and traffic manager resources usage, where X
can be one of the following:
• All - Ingress and Egress resources snapshots
• Port {id |all} queue {all} - egress queue-level snapshot for
both unicast and multicast packets
• 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
snapshot for multicast packets only
• Port {id |all} prio-group {id | all} - ingress priority-group

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.
