Inventory

Problem:	Try this:
"Error connecting" with error messages “Error setting up shell channel:”or “Error opening shell channel”	Likely caused by network connectivity issues or SSH is misconfigured. Confirm connection with alternate SSH client
"Timeout" or “Error retrieving data" with error messages “Command: XXX has timed out."	* Try the command with alternate SSH client * Increase timeout
"Error connecting " or “Invalid login credentials" with error messages “Could not communicate with the device:"	* Check IP address * Check user name and password * Confirm connection with alternate SSH client
