Configure MTU Size on an Interface
In Dell EMC Networking OS, Maximum Transmission Unit (MTU) is defined as the entire Ethernet packet (Ethernet header +
FCS + payload).
The following table lists the range for each transmission media.

594-12000 = link MTU
576-9234 = IP MTU
Link Bundle Monitoring
Monitoring linked LAG bundles allows traffic distribution amounts in a link to be monitored for unfair distribution at any given
time. A threshold of 60% is defined as an acceptable amount of traffic on a member link. Links are monitored in 15-second
intervals for three consecutive instances. Any deviation within that time sends Syslog and an alarm event generates. When the
deviation clears, another Syslog sends and a clear alarm event generates.
The link bundle utilization is calculated as the total bandwidth of all links divided by the total bytes-per-second of all links. If you
enable monitoring, the utilization calculation is performed when the utilization of the link-bundle (not a link within a bundle)
exceeds 60%.
To enable and view link bundle monitoring, use the following commands.
● Enable link bundle monitoring.
ecmp-group
● View all LAG link bundles being monitored.
show running-config ecmp-group
● Enable link bundle monitoring on port channel interfaces.
link-bundle-monitor enable
DellEMC(conf-if-po-10)#link-bundle-monitor enable
● Configure threshold level for link bundle monitoring.
link-bundle-distribution trigger-threshold
DellEMC(conf)#link-bundle-distribution trigger-threshold
● View the link bundle monitoring status.
