The MTU size is restricted to prevent an ICMP-based attack. An ICMP-based attack could reduce the MTU size to very low value. A very low MTU size could cause a severe decrease in performance. However, an MTU size that is restricted to 576 bytes may affect certain WAN scenarios, such as satellite links. In these WAN scenarios, the MTU size might

Network MTU can be increased via OpenStack CLI( latest version - 4.0.0 ) or via API call. To increase the MTU size via CLI OpenStack CLI use the following command # openstack network set --mtu 8950 Note: MTU option in the command is only available in … microHOWTO: Change the MTU of a network interface A common reason for wanting to increase the MTU of an interface is to improve the throughput of high-speed Ethernet. The standard Ethernet MTU has remained fixed at 1500 bytes for backward compatibility with 10 and 100 megabit networks, however this is far from optimal at speeds of 1 gigabit and above. Configuring System MTU - Cisco

To verify the MTU size on Aruba HPE Switch, collect "show tech all" and look for "ghsNetStatShow". This will show the MTU size for all the VLAN interface. There are no CLI commands available to increase/modify default MTU size on Aruba HPE Switch, but jumbo frames can be enabled on respective VLAN, if packet size are found to be exceeding 1500
