ip mtu
This command sets the IP Maximum Transmission Unit (MTU) on a routing interface. The IP MTU is the size of the largest
IP packet that can be transmitted on the interface without fragmentation. Unified Switch software currently does not fragment
IP packets.
• Packets forwarded in hardware ignore the IP MTU.
• 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.
Note: The IP MTU size refers to the maximum size of the IP packet (IP Header + IP 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 "mtu" on page
Default 1500 bytes
Format
ip mtu <68-1500>

15) must take into account the size of the Ethernet header.
