A number of devices are showing as 'failed' in archive management. The error message is "TELNET: Failed to establish TELNET connection to x.x.x.x - Cause: Authentication failed on device 3 times. PRIMARY-RUNNING config Fetch Operation failed for TFTP. Could not detect SSH protocols running on the device Failed to fetch config using RCP.Verify RCP is enabled or not."
I have one set of credentials for all devices. Not sure why some are failing. Any help would be appreciated.
