2023年5月30日 · Here we can see that MTU of the loopback interface is 65536B, and 1500B for enp0s31f6, which is a Ethernet interface. It can be set using ip link set dev <interface> mtu <value>, where <interface> is the interface name. ip link set dev enp0s31f6 mtu 1400 would set the MTU of emp0s31f6 to 1400 bytes. Should I change it? Generally speaking, no.
