- Outlines how to set a custom MTU size to configure your cluster to utilize jumbo frames.
- Cluster running Qumulo Core
Consult your Network Administrator before making any changes to the MTU value. Service disruption can occur if an incorrect value is set.
Note that the suggested values of 1500 and 9000 do not include the packet overhead. Packet drop or fragmentation can occur if you choose an MTU that is incompatible with your networking environment.
Qumulo core provides the ability to set custom TCP Maximum Transmission Unit (MTU) sizes to configure jumbo frames.
To set a custom MTU size:
- Navigate to the Cluster > Network Configuration panel in the Web UI
- Use Static IPs (if not already doing so) in your Network Configuration. Custom MTUs can only be set if Static IPs are used.
- Adjust the MTU size based on your networking environment. Presets for 1500 and 9000 (Jumbo Frames) MTUs are provided as well as the option for custom MTU in the non-standard input box.
- Once the desired value has been set, click on the Save button at the bottom of the screen. The changes will be propagated throughout the cluster and you will be returned to the Network Configuration screen.
You should now be able to successfully configure your cluster to use jumbo frames by adjusting the MTU accordingly.
