I had a problem with Software Image Management for the upgrade of a switch.
It seems that at the end of the upgrade, CiscoWorks was unable to save the configuration with telnet.
Yet, telnet seems to be ok because CiscoWorks manages to connect to the switch at the beginning of the upgrade.
Updating config file during software upgrade process
Device running-config is modified but failed to save the running-config to startup-config.Cause:
Could not detect SSH protocols running on the device
TELNET: Failed to establish TELNET connection to 10.1.3.4 -
Cause: Authentication failed on device 3 times.
I sent attached the logs of the upgrade.
Thank you in advance.
Does the Device crendential verification report succeeds or fail? Is config Archive failing for one device or all?
If the devices are configured for AAA the you have to modify the Tacacsprompt.ini file for telnet to work successfully.
For procedure on editing the file, see my post :
yes, the DCR verification report is succeed :
|1.||switch03-d||Ok(Primary Successful)||Ok(Primary Successful)|
|2.||switch04-d||Ok(Primary Successful)||Ok(Primary Successful)|
I have modify the tacacsprompt.ini and reload an upgrade of the switchs at 13:28 pm for testing. It is 16:33 pm and the upgrade is still running...
3 hours for upgrade 2 switchs ? The upgrade seems to be blocked or looped in swim_log.
The job fails last night after timeout.
I have reschedule job this morning for 2 switchs :
The device credentials verification job seems to be coherent :
|Device Name|| Read |
| Read Write |
|Telnet|| Enable |
|SSH|| Enable |
|1.||switch04-d||Ok||Ok||Ok(Primary Successful)||Ok(Primary Successful)||Failed to connect.||Did Not Try|
|1.||switch03-d||Ok||Ok||Ok(Primary Successful)||Ok(Primary Successful)||Ok(Primary Successful)||Ok(Primary Successful)|
But the job fails again cause telnet authentication failed on device 3 times.
I do not understand why LMS does not use ssh if possible at the finish of the job? Why telnet authentication fails ?
Thanks in advance.
