bytes
Maximum transmission unit of IP packets ranging from 68 to 1500
bytes
Defaults The MTU is the same as the MTU value configured by the interface command mtu.
Command
Mode
Interface configuration mode
Usage Guide
If an IP packet is larger than the IP MTU, the RGOS software will split this packet. All the devices in
the same physical network segment must have the same IP MTU for the interconnected interface.
If the interface configuration command mtu is used to set the MTU value of the interface, IP MTU will
automatically match with the MTU value of the interface. However, if the IP MTU value is changed,
the MTU value of the interface will remain unchanged.
Configuration
Examples
The following example sets the IP MTU value of the FE interface 0/1 to 512 bytes.
interface fastEthernet
0/1
ip mtu 512
