If the packet includes a Layer 2 header, the difference between the link MTU and IP MTU (ip mtu
command) must be enough bytes to include the Layer 2 header:
•
On C-Series, the IP MTU will get adjusted automatically when the Layer 2 MTU is configured
with the mtu command.
•
On the E-Series, you must compensate for a Layer 2 header when configuring IP MTU and link
MTU on an Ethernet interface. Use the ip mtu command.
