Hi,
If dpdk plugin used, which is the default case in VPP, MTU to each
interface is set by retrieving MTU information from underlying DPDK PMD
API: rte_eth_dev_info_get(). So if the device supports max MTU say 9216
then that will be configured.
I don't think setting MTU via vpp cli or startup.config is supported.
Although it should be easy to implement by adding dpdk plugin cli by
calling rte_eth_dev_set_mtu().
Thanks,
Nitin

Hi
I set mtu to all of my interfaces using "vppctl set interface mtu 1500
<interface>".
But when I generate packets larger than mtu size, all packet pass
through vpp. Is there any parameter that I must set?
I generate large packet using "ping -M do -s 9472 200.200.200.40".
My vpp version: master v18.07-rc0~147-g7220f42c
Thanks,
Sincerely
