Congure MTU Size on an Interface
In Dell EMC Networking OS, Maximum Transmission Unit (MTU) is dened as the entire Ethernet packet (Ethernet header + FCS +
payload).
The following table lists the range for each transmission media.
Transmission
Media
MTU Range (in bytes)
Ethernet
592-9216 = link MTU
576-9398 = IP MTU
The IP MTU automatically congures.
Link Bundle Monitoring
Monitoring linked LAG bundles allows trac distribution amounts in a link to be monitored for unfair distribution at any given time. A
threshold of 60% is dened as an acceptable amount of trac 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
• Congure threshold level for link bundle monitoring.
link-bundle-distribution trigger-threshold
DellEMC(conf)#link-bundle-distribution trigger-threshold
• View the link bundle monitoring status.
show link-bundle-distribution
