Perform a Ping on the Cluster Control Link

You can check to make sure all the cluster nodes can reach each other over the cluster control link by performing a ping. One major cause for the failure of a node to join the cluster is an incorrect cluster control link configuration; for example, the cluster control link MTU may be set higher than the connecting switch MTUs.

Procedure

Step 1

Choose Devices > Device Management, click the More (more icon) icon next to the cluster, and choose > Cluster Live Status.

The node sends a ping on the cluster control link to every other node using a packet size that matches the maximum MTU.
