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
Dell#show hardware stack-unit 1 buffer-stats-snapshot unit 3 resource interface all queue
mcast 3
Unit 1 unit: 3 port: 1 (interface Fo 1/144)
