How do I find the MTU size on my HP switch?
A: 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.

When should I enable jumbo frames?
When should jumbo frames be used? Use jumbo frames only when you have a dedicated network or VLAN, and you can configure an MTU of 9000 on all equipment, to increase performance. A good example of this approach is a separate SAN or storage network.
Do jumbo frames make a difference?
The throughput achieved with jumbo frames is around 985 Mbps as compared to 934 Mbps with standard Ethernet frames. We observe that use of jumbo frames in one-to-one file transfer provides a 5.5% potential benefit over standard Ethernet frames even when utilizing full link capacity.
How do you set jumbo frames?
Right-click the NIC for which you want to enable jumbo frames and select Properties. Under the Networking tab, click the Configure button for the network adapter. Select the Advanced tab. Select Jumbo Frame and change the value from disabled to the desired value, such as 9kB MTU or 9,014 Bytes, depending on the NIC.

How do I turn on jumbo frames in Aruba switch?
What happens if MTU is too high?
Generally, if your MTU is too large for the connection, your computer will experience packet loss or dropping internet connection. To determine the correct MTU size for your network, you’ll have to do a specific ping test on the destination you’re trying to go to like using another computer or a web address.
What should my MTU size be?
Add 28 to that number (IP/ICMP headers) to get the optimal MTU setting. For example, if the largest packet size from ping tests is 1462, add 28 to 1462 to get a total of 1490 which is the optimal MTU setting.
Does the HPE MTU support jumbo frames?
Looking at numerous HPE documents outlining configuration and best practices, the documents did confirm that the unit supported Jumbo Frames. However, the documentation on the MTU was never clearly stated and can be confusing.
How to enable jumbo frames on HP ProCurve switch?

What is the difference between the default MTU and Jumbo MTU?
When the switch applies the default MTU (1522-bytes including 4 bytes for the VLAN tag) to a VLAN, all ports in the VLAN can receive incoming frames of up to 1522 bytes. When the switch applies the jumbo MTU (9220 bytes including 4 bytes for the VLAN tag) to a VLAN, all ports in that VLAN can receive incoming frames of up to 9220 bytes.
What happens to frames larger than the MTU allowed on Port?
The switch drops any inbound frames larger than the MTU allowed on the port. Ports operating at a minimum of 1 Gbps can accept forward frames of up to 9220 bytes (including four bytes for a VLAN tag) when configured for jumbo traffic.
