Failed Stack Node

If the show stacking command shows the stack state for a slot as Failed, check the following things:

Does the show stacking stack-ports command show a port state as Inhibited? If so, the problem might be a duplicate slot number. If more than one node is using the same slot number, change the slot number on one of the affected nodes to a unique slot number.
Is the affected node isolated by other nodes for which the stack state is listed as Disabled? If so, you need to enable stacking on the disabled nodes.
Enter the show slot detail command. If the command displays License Mismatch, either upgrade the node license, or configure a license level restriction so that all master-capable nodes are at the same effective license level.
Enter the show slot detail command. If the command displays Incompatible EXOS Version, log into the master node and use the synchronize slot command to update the failed node.
