show hardware stack-unit buffer-stats-snapshot View the buffer statistics tracking resource information with polling details and historical snapshots. Syntax Parameters show hardware stack-unit stack-unit-number buffer-stats-snapshot unit number resource X history Y stack-unit unitnumber buffer-statssnapshot unit number unit resource X 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. Display the historical snapshot of buffer statistical values 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. 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 history Y Historical snapshot details of buffer space statistics, where Y can be one of the following: ● Instance {all | id} - Displays the information for all instances or the specified instance of the snapshot. ● Summary - Displays the consolidated information pertaining to the preceding three instances of the snapshot values collected in history.

Usage Information When you enter the instance all option, show hardware stack-unit unit-number bufferstats-snapshot unit 0 resource X output for all available instances on the history collection is displayed. When you enter the instance id option, show hardware stack-unit unit-number bufferstats-snapshot unit 0 resource X for specified instance alone is displayed. When you enter the summaryoption, show hardware stack-unit stack-unit-number bufferstats-snapshot unit 0 resource X will be enhanced to display the total buffered cells, shared cells, headroom cells for last 5 instances in the table format. If information for specified instance id is not available when you enter the show command, which occurs if you issue the command before the time elapsed for the snapshot to be captured for that instance ID, the following informational message is displayed on the console:%Info: Data for instance id id is not available. If information for specified instance id id is not available when you enter the show command, which occurs if you issue the command before the time elapsed for the snapshot to be captured for that instance ID, the 564 Data Center Bridging (DCB)
