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

Usage Information

The following information is displayed based on the buffer-info type, such as device-level details, queue-based snapshots, or priority group-level snapshot in the egress and ingress direction of traffic:

• Device-ingress – Displays total buffer accounting usage for the unit.

• Device-egress –Display total buffer usage for the unit, total multicast buffer usage for the unit and also on per-service-pool basis. Counters will be displayed for the 2 service-pools – one for normal traffic and other for DCB traffic.

When the buffer-stats-snapshot is disabled, the following informational message is displayed when you run the show command: %Info: Buffer-stats-snapshot feature is disabled.
