    mtu (Mobile Interface)

    Syntax

    mtu mtu-size;

    Hierarchy Level

    [edit interfaces interface-name]

    Release Information

    Statement introduced in Junos OS Mobility Release 11.2W.

    Description

    Configure the maximum transmission unit (MTU) size for the mobile interface. MTU sizes can be important because the GPRS tunneling protocol (GTP) tunneling can cause a data unit to exceed the maximum frame size when the tunnel headers are added, which causes an error. However, larger MTU sizes increase throughput.

    Options

    mtu-size—MTU size.

    Range: 256 through 9192 bytes

    Default: 500 bytes (INET, INET6, and ISO families), 1448 bytes (MPLS)

    Required Privilege Level

    interface—To view this statement in the configuration.

    interface-control—To add this statement to the configuration.
