Administrator Guide

1. Create a 10-Gigabit Ethernet interface.
DellEMC(conf)#interface TenGigabitEthernet 1/1/1/1
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.
DellEMC(conf-if-te-1/1/1/1)#Service-class buffer shared-threshold-weight queue5 4 queue7 6
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
DellEMC(conf)#buffer-stats-snapshot
DellEMC(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
DellEMC(conf)#buffer-stats-snapshot
DellEMC(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. Use show hardware buffer-stats-snapshot resource interface interface{priority-group { id |
all } | queue { ucast{id | all}{ mcast {id | all} | all} to view buffer statistics tracking resource information
for a specific interface.
