Enabling Buer Statistics Tracking
You can enable the tracking of statistical values of buer spaces at a global level. The buer statistics tracking utility operates in the
max use count mode that enables the collection of maximum values of counters.
To congure the buer statistics tracking utility, perform the following step:
1. Enable the buer statistics tracking utility and enter the Buer Statistics Snapshot conguration mode.
CONFIGURATION mode
Dell(conf)#buffer-stats-snapshot
Dell(conf)#no disable
You must enable this utility to be able to congure the parameters for buer statistics tracking. By default, buer statistics
tracking is disabled.
2. Enable the buer statistics tracking utility and enter the Buer Statistics Snapshot conguration mode.
CONFIGURATION mode
Dell(conf)#buffer-stats-snapshot
Dell(conf)#no disable
You must enable this utility to be able to congure the parameters for buer statistics tracking. By default, buer statistics
tracking is disabled.
3. To view the buer statistics tracking resource information depending on the type of buer information, such as device-level
details, queue-based snapshots, or priority group-level snapshot in the egress and ingress direction of trac, use show
hardware stack-unit <id> buffer-stats-snapshot unit <id> resource x
EXEC/EXEC Privilege mode
