Configuring IP MTU


The following feature is available on the switches covered in this guide. jumbos support is required for this feature. On switches that do not support this command, the IP MTU value is derived from the maximum frame size and is not configurable.

You can set the IP MTU globally by entering this command. The value of max-frame-size must be greater than or equal to 18 bytes more than the value selected for ip-mtu. For example, if ip-mtu is set to 8964, the max-frame-size is configured as 8982.


jumbo ip-mtu <size>

Globally sets the IP MTU size. Values range between 1500 and 9198 bytes. This value must be 18 bytes less than the value of max-frame-size.

(Default: 9198 bytes)
