• View all LAG link bundles being monitored.
show running-config ecmp-group
Link bundle monitoring can be also enable on port-channels, here it is the way it can be congured:
interface Port-channel 111
no ip address
switchport
no shutdown
link-bundle-monitor enable
To view the links that are being monitored, use the show link-bundle-distribution command.
Dell(conf-if-po-111)#do show link-bundle-distribution

Monitoring HiGig Link Bundles
You can monitor the HiGig link bundles that transmit data between internal backplane ports on line-card (leaf) and switch fabric module
(SFM - spine) network processing units (NPUs) and generate a system log message or SNMP trap when trac distribution in a link bundle
is uneven. Each NPU is a Trident chip.
On the switch, backplane port channels operate as HiGig link bundles to transmit data trac between line-card and SFM NPUs. There are
11 line-card and 2 SFM NPUs. The two SFM (spine) NPUs include the switch fabric module.
Each line-card use one NPU numbered 0. SFM NPUs are numbered 0 to 1.
Line-card and SFM NPUs use HiGig link bundles to transmit data.
• An SFM (spine) NPU uses 10 HiGig link bundles, one link bundle to transmit data to each line-card (leaf) NPU. Each HiGig link bundle in
an SFM NPU consists of three HiGig links.
• A line-card (leaf) NPU supports 24 front-end I/O ports and 6 backplane HiGig ports. The six backplane links are members of 2 HiGig
link bundles that connect the line-card NPU to each SFM (spine) NPU. Three HiGig links in the bundle are used to connect to each
SFM NPU
You can enable the capability to detect uneven trac distribution in the member links of a HiGig link bundle on a line-card or SFM NPU. You
can also enable a notication to be sent using alarms and SNMP traps. The algorithm used to determine uneven distribution of trac is
predened.
Monitoring HiGig link bundles allows you to view and analyze unequal trac ow in backplane port channels and take corrective action.
Alarms are generated if the link-bundle trac threshold is greater than the congured threshold and the unevenness is greater than 10
percent between links for three successive rate-intervals. Alarms are removed when the link-bundle threshold is lower than the congured
threshold and the unevenness is less than 10 percent between links for three successive rate intervals.
An alarm includes the following information:
• Line-card or SFM NPU unit and HiGig port-channel ID in the format: hg-port-channel slot slot/npu-id/hg-port—
channel-id
• Alarm: triggered or cleared
Examples of the system log messages triggered when the threshold for a HiGig link bundle/port channel is exceeded are:
