What is the default MTU size on Aruba HPE Switches and how to validate the same?


Unlike Mobility Access Switches, who's MTU size is 1514 bytes by default, Aruba HPE Switch has a default MTU size of 1500 bytes only. 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 bytes.
