= Checking the current cluster MTU value

[role="_abstract"]
To ensure network stability and performance in a hybrid environment where part of your cluster is in the cloud and part is an on-premise environment, you can obtain the current maximum transmission unit (MTU) for the cluster network.

.Procedure

* To obtain the current MTU for the cluster network, enter the following command:
