● 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:
show hardware stack-unit buffer-stats-snapshot (Total Buffer
Information)
View the buffer statistics tracking resource information depending on the type of buffer information, such as device-level
details, port-level counters, queue-based snapshots, or priority group-level snapshot in the egress and ingress direction of
traffic.
Syntax
show hardware stack-unit <id> buffer-stats-snapshot unit <id> 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.
buffer-stats-
snapshot unit
number
Display the historical snapshot of buffer statistical values unit Enter the keyword
unit along with a port-pipe number. The range is from 0 to 0.
buffer-info Buffer and traffic manager resources usage, where X can be one of the following:
● All - Displays ingress and egress device, port, and queue snapshots
● Interface all queue {all} - egress queue-level snapshot for both unicast and
multicast packets
