Backup Failed.

It sounds like the application is having trouble talking to the built-in TFTP server. This might be due to port contention on UDP port 69. This port is used by TFTP and PXE applications. I would suggest rebooting the system to clear any unused ports and verify that UDP port 69 is not in use before starting the application.

You can use a freeware program called Active Ports to scan the ports on the system and end any processes to clear the necessary ports.

I've checked the active ports and port 69 is only used by the openmanage application.

Another message is given after I refresh the job tree.......

"Mediation Exception occured on device XXXXXXX.  Review log database for more information."

I see this in the appserver.log

08:25:17,828 ERROR [com.dorado.redcell.devicedriver.base.MessageUtil] Timeout has occurred.  Device may not be responding.

Is there something I have to have in the switch config to allow me to pull the config?   Does it use the username and password I used to discover the device, or does it use SNMP strings to connect to and pull the config?

I see the following on the switch when a backup is attempted.

04-Aug-2004 08:23:50 %ERHG-I-SEND: Access attempted by unauthorized NMS

 

 

The "Mediation Exception... " error indicates that the application cannot properly communicate with the switch. This is usually due to the device not being discovered properly. This error combined with the "Unauthorized NMS" error leads me to believe that there is a problem with either the SNMP configuration on the switch, or the telnet credentials configured in the application.

For the 3300/6000 series switches, you should configure the switch to allow a host with "su" (super) access. The command for this would be:

console(config)# snmp-server community su

Once you change this configuration on the switch, delete the switch from the Equipment Manager and re-discover it. During the discovery, the application should recognize the vendor as Dell. If it does not, then the discovery is not completeing properly.

The other common problem are the telnet credentials. You must use the credentials of a user on the switch with admin (level 15) privilege.

That was it!!!!    Backups are working!  

Thanks!!!

 

But.......now that I have a bunch of SNMP and TELNET authentication credentials created, how can I delete the ones I don't need?    I don't see a delete button for removing those.....

 

 

You should be able to modify/delete them from the Settings/Permissions/Authentication Manager window.

Yeah.........right where you said.

 

Thanks for the help!!!

Ok, I must be dense.  I am also getting what seems to be the same backup error.  Mediation etc etc.  I added the snmp community su to the switch and still no go.  Mentioned also was possible telnet admin priv.  Is this added under ONM?  Under equipment manager, I clicked on the device, chose open, authentication, then under authencitcation profiles, added my username and password that allows me access to the switch.  I then opened a dos window, telneted to the switch using that name and password just to be sure it worked ok and it does.  What am I missing?-

When you added the community string with su privilege, did you specify the ip address of the management station? To access the switch via SNMP, the management station must be entered into the host table.
