frequently. The receive buffer must be large enough to save all data that is received when the system
processes a PFC PAUSE frame.
You can use the service-class buffer shared-threshold-weight queue0 ... queue7 number
command in Interface Configuration mode to specify the threshold weight for the shared buffer for each of
the queues per port.
1 Create a 10-Gigabit Ethernet interface.
Dell(conf)#interface TenGigabitEthernet 1/1/1
2 Configure the threshold weight of the shared buffer for the queues you want. In this example, this setting
is configured for queues 5 and 7.
Dell(conf-if-te-1/1/1)#Service-class buffer shared-threshold-weight queue5 4

Enabling Buffer Statistics Tracking
You can enable the tracking of statistical values of buffer spaces at a global level. The buffer statistics tracking
utility operates in the max use count mode that enables the collection of maximum values of counters.
To configure the buffer statistics tracking utility, perform the following step:
1 Enable the buffer statistics tracking utility and enter the Buffer Statistics Snapshot configuration mode.
CONFIGURATION mode
Dell(conf)#buffer-stats-snapshot
Dell(conf)#no disable
Enable this utility to be able to configure the parameters for buffer statistics tracking. By default, buffer
statistics tracking is disabled.
2 Enable the buffer statistics tracking utility and enter the Buffer Statistics Snapshot configuration mode.
CONFIGURATION mode
Dell(conf)#buffer-stats-snapshot
Dell(conf)#no disable
Enable this utility to be able to configure the parameters for buffer statistics tracking. By default, buffer
statistics tracking is disabled.
3 To view the buffer statistics tracking resource information depending on the type of buffer information,
such as device-level details, queue-based snapshots, or priority group-level snapshot in the egress and
ingress direction of traffic, 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
