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 in the UI.
- Login to the Web UI
- Hover over Cluster and select Network Configuration in the dropdown
NOTE: Custom MTUs can only be set if Static IPs are used so Switch to Static IP in your Network Configuration if needed for configuration
- Click Switch to Static IP
- 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.
- Click Save once the desired value has been set
The changes will be propagated throughout the cluster and you will be returned to the Network Configuration screen. Note that you may need to re-login for changes to take effect.
You should now be able to successfully configure your cluster to use jumbo frames by adjusting the MTU accordingly
