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 Media Ethernet MTU Range (in bytes) 594-12000 = link MTU 576-9234 = IP MTU 386 Interfaces
