• The rate interval for polling the traffic statistics for member links of the high-Gigabit port channel must be configured. Thedefault hiGig stats polling interval is 15 seconds. This interval cannot be configured per high-Gigabit port channel and is applicablefor all of the high-Gigabit port channels on the system.• The threshold value identifies when to start the link bundle utilization calculation trigger (default of 60 percent). When overallutilization (mean) is below this value, link bundle distribution unevenness is not reported.• If unevenness is observed over three consecutive measurements, an alarm event is generated. The rateInterval for Hg statspolling (default 15 seconds) determines the time interval between two measurements. Alarm clear is sent when evenness isobserved for three successive rate intervals. If individual link utilization information is not available for a given timestamp, linkbundle utilization is not calculated at that timestamp. The previous known record shall be used for the alarm calculation.• Turning on and off the link bundle monitoring is performed at a high-Gigabit Ethernet port-channel level configuration.• The difference of utilization % between the high-used link and low-used link is used to determine the alarm condition. The alarmtrigger reporting is based on the same algorithm used for link bundle monitoring on LAG/ECMP. The alarm reporting is triggeredwhen the configured threshold has crossed for a given bundle. Now, if the delta utilization is beyond 10%, an alarm is raised. Thealarm condition remains active until all interface utilizations are within the band or until the overall utilization goes below thetrigger threshold. An alarm is not raised or cleared instantaneouslyEnabling the Verification of Member Links Utilization in a High-GigabitPort ChannelThis procedure is supported on the Z9000 platform.To examine the working efficiency of the high-Gigabit Ethernet port channel interfaces, perform the following steps:1. Use the hg-link-bundle-monitor slot slotId npuUnit npuUnitId hg-port-channel portChannelIdenable command in Global Configuration mode to enable this functionality to detect the working efficiency of the high-Gigabitport channel bundle interfaces.CONFIGURATION modeDell(conf)#hg-link-bundle-monitor slot 0 npuUnit 0 hg-port-channel 0 enable2. Specify the trigger threshold for higig link bundle monitoring.CONFIGURATION modeDell(conf)#hg-link-bundle-monitor trigger-threshold 303. Specify the interval in seconds for higig link bundle monitoring.CONFIGURATION modeDell(conf)#hg-link-bundle-monitor rate-interval 104. Enable the generation of traps for higig link-bundle monitoring.CONFIGURATION modeDell(conf)#snmp-server enable traps hg-lbm5. Use the show hg-link-bundle-distribution command to display the traffic-handling and utilization of the memberinterfaces of the port channel. The following table describes the output fields of this show command.EXEC, EXEC Privilege modesDell#show hg-link-bundle-distribution 0 npuUnit 5 hg-port-channel 0Viewing Buffer Utilization and Queue Statistics on High-GigabitEthernet Backplane PortsThis functionality is supported on the Z9000 platform.You can now view the queue statistics and buffer utilization counters for the internal leaf port and spine port queues using theappropriate show commands. Transmit and receive counters and drop counters per queue are computed and displayed for internal390 Link Aggregation Control Protocol (LACP)
