Version Description
9.10(0.0) Introduced on the S6100–ON.
9.8(0.0) Introduced on the Z9100.
9.7(0.0) Introduced on the S6000-ON.
Version 9.3(0.0) Introduced on the S6000 platform.
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
• Interface all queue ucast {id | all} - egress queue-level snapshot for unicast packets
only
• Interface all queue mcast {id | all} - egress queue-level snapshot for multicast packets
only
• Interface all prio-group {id | all} - ingress priority-group level snapshot
