Parameters

size: Sets the MTU in bytes. The value range for this argument is 46 to 9198.

Usage guidelines

If you configure both the mtu and ip mtu commands on a VLAN interface, the MTU set by the ip mtu command is used for fragmentation. For more information about the ip mtu command, see Layer 3—IP Services Command Reference.

Examples

# Set the MTU to 1492 bytes for VLAN-interface 1.

<Sysname> system-view
[Sysname] interface vlan-interface 1
