Configure MTU Size on an Interface
In Dell Networking OS, Maximum Transmission Unit (MTU) is defined as the entire Ethernet packet (Ethernet header + FCS +
payload).
The link MTU is the frame size of a packet, and the IP MTU size is used for IP fragmentation. If the system determines that the IP
packet must be fragmented as it leaves the interface, Dell Networking OS divides the packet into fragments no bigger than the size
set in the ip mtu command.
NOTE: Because different networking vendors define MTU differently, check their documentation when planning MTU
sizes across a network.
The following table lists the range for each transmission media.
Transmission MTU Range (in bytes)

594-12000 = link 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
