27.9.3 Physical interconnect warnings and errors

Symptom Possible cause and recommendation

Interconnect-level	Interconnect warnings or errors due to:
warnings or errors	• Downlink with a deployed connection is not operational
	• Downlink with a deployed connection is not operational
	• Incorrect firmware version (different from firmware baseline version)
	•	Configuration error
	•	Hardware fault
	•	Lost communication
	• Connection and redundancy status (no redundant paths)
	•	Administratively disabled ports

27.10 Troubleshooting networks

27.10.1 Network create operation is unsuccessful

Symptom Possible cause and recommendation

Network creation is	The prerequisites have not been met
unsuccessful	1.	Verify that the prerequisites listed in the online help have been met.
	1.
	2.	Retry the create network operation.
	The network was configured incorrectly
	1.	Verify that:
		• The VLAN ID is in the range of valid integers (2 through 4092).
		• The network name is unique.
		• The network bandwidth is within the range indicated by the UI. The preferred bandwidth
		must be less than the maximum bandwidth.
	2.	Retry the create network operation.

27.11 Troubleshooting server hardware

27.11.1 Server add or remove is unsuccessful

If the add server action is not successful, a notification panel provides the reason why the add action failed and provides a solution to the problem. Often, the resolution is to click the add link
