show hardware stack-unit buffer-stats-snapshot
View the buffer statistics tracking resource information without polling details and historical snapshots.
Syntax
show hardware stack-unit stack-unit-number buffer-stats-snapshot unit
number resource X
Parameters
stack-unit stack-
unit-number
Unique ID of the stack unit to select a particular stack member and then enter
one of the following command options to display a collection of data based on the
option entered. The range is 0 to 11.
buffer-stats-
snapshot unit
number
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 level snapshot

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.
Example 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:
