The difference in utilization percentage between the high-used link and low-used link determines the alarm condition. Alarm
reporting for link-bundle monitoring is based on the same algorithm used for LAG/ECMP. An alarm condition occurs when
the unevenness in link-bundle utilization exceeds 10 percent of the configured threshold and remains active until traffic on
member links falls below the trigger threshold. If unevenness is recorded for three consecutive measurements, an alarm
event is generated. The rate interval defines the time interval between measurements.
Enabling HiGig Link-Bundle Monitoring
To enable the monitoring of HiGig link bundles, follow these steps.
1. Enable the monitoring of traffic distribution on the member links in a HiGig link bundle (port-channel).
CONFIGURATION mode
Dell(conf)#hg-link-bundle-monitor {sfm npu-id hg-portchannel hg-portchannel-id | slot
slot npuUnit npu-id hg-portchannel 0} enable
2. Specify the trigger threshold for HiGig link-bundle monitoring.
CONFIGURATION mode
Dell(conf)#hg-link-bundle-monitor trigger-threshold percentage
3. Specify the interval (in seconds) when HiGig link-bundle monitoring is performed.
CONFIGURATION mode
Dell(conf)#hg-link-bundle-monitor rate-interval seconds
4. Enable SNMP trap generation for HiGig link-bundle monitoring.
CONFIGURATION mode
Dell(conf)#snmp-server enable traps hg-lbm
5. Display the traffic utilization of member links in a HiGig link bundle (port channel).
EXEC, EXEC Privilege modes
Dell#show hg-link-bundle-distribution {sfm npu-id hg-portchannel hg-portchannel-id |
slot slot npuUnit npu-id hg-portchannel 0}
Non Dell-Qualified Transceivers
The system supports Dell-qualified transceivers and only some of the non Dell-qualified transceivers.
The system supports the following cables and adapters:
DAC cables
AOC cables
AOC fan-out cables
DAC fan-out cables
40G fiber breakout cables
10G AOC and DAC cables
1G optics
QSA
If you use any of the cables or adapters in the preceding list that is not Dell-qualified, the Dell Networking OS detects it and
makes it operational. The system displays a syslog message similar to the following:
Apr 29 05:09:16: %S4048-ON:1 %IFAGT-5-UNSUP_OPTICS: Non-qualified optics in slot 1 port
49
The system supports the following types of transceivers only if they are Dell-qualified:
LR4
SR4
436
