IMC 7 Config deploy not working

[markopolo]

Hi, I am having a problem with deploying config templates out to my 2920 series switches using IMC.

Telnet is set as the connection option in IMC and I can connect via putty to it. When I try to deploy or run a backup using TFTP the failure message is "TFTP server is not started" however, I have a TFTP server on the IMC server and can connect to it directly using the switch to copy or download. 

The log has errors which are as follows:

 I have also tried with SSH/SFTP settings for config deployment and get the same error message. Any advice would be appreciated.

Cheers,

First guess would be that you don't have correct Telnet/SSH credentials assigned.

If you've got it set to Telnet mode, can you find the device in IMC, go to Configure -> Modify Telnet Settings, then click Test?

Do the same with SSH.

Hi Lindsay,

Thanks for getting back to me.

I can confirm that testing telnet, SSH for individual devices completes successfully. I can also update the switches firmware and deploy CLI commands via deployment task successfully.

Regards,

Mark

Hmmm. Well, those tests verify that credentials are all good.

I have seen something similar before (specifically where you see this log: "Failed to exec cmd: close, error message: spawn_id: spawn id exp4 not open"), but I can't recall the exact circumstances.

Next things I'd be looking at:

* If you're using SFTP, check that 'ip ssh filetransfer' is configured

* If you're using Telnet, capture all traffic between the switch & IMC, and analyse what commands it's sending, and where it's getting stuck. Correlate these with the logfiles, and any temp files created in <IMC>/server/tmp.

If you like, you could email me the PCAP and log file, and I'll see if I can work out what's going on - lindsay AT lkhill DOT com.

You try to deploy the new configuration as a segment or CLI command?

If I remember well, to Procurve switches the segment method doesn't work, you can upload config only via CLI mode.
