Encapsulation; Show Ip Brief - D-Link DWL-8500AP Command Reference Manual

• Packets forwarded in software are dropped if they exceed the IP MTU of the outgoing
interface.
Packets originated on the router may be fragmented by the IP stack. The IP stack uses its
default IP MTU and ignores the value set using the ip mtu command.
The IP MTU size refers to the maximum size of the IP packet (IP Header + IP
NOTE:
payload). It does not include any extra bytes that may be required for Layer-2
headers. To receive and process packets, the Ethernet MTU (See
page 39.) must take into account the size of the Ethernet header.
