LMS 4.1 - Smart Install generates wrong configuration for DI?

Hi,

I'm testing the Smart Install Feature with LMS and want to use LMS as the TFTP Server.

The SI Director Wizzard seems to push the wrong configuration to the Director, since it deploys a TFTP configuration with 127.0.0.1 to the switch:

#MODE_CONFIG

vstack director 192.168.1.236

vstack basic

vstack hostname-prefix SIClient_

vstack group built-in 3750e 48poe

config tftp://127.0.0.1/swwien_version_2.txt

image tftp://127.0.0.1/c3750e-universalk9-tar.122-58.SE2.tar

Anyone knows why this happens?

Thanks in advance!

LMS 4.1 - Smart Install generates wrong configuration for DI?

Check if you hosts file in windows has an entry with the servers name and 127.0.0.1.

If so remove it or hash # it out.

Cheers,

Michel

Re: LMS 4.1 - Smart Install generates wrong configuration for DI

Yes, that caused this issue- thanks Michel!

Now, there seems to be still some TFTP related issues on LMS:

After configuring vstack, this error occurs:

*Mar  1 05:54:38.861: VSTACK_ERR:

!! smi_tftp_image_list_to_tftp_server: tftp://172.22.210.205/3750e-48poe-imagelist.txt Image List Transfer failed!

Looks like this is an upload from the DI to the TFTP Server (LMS).

So I tried to push another file to the Server maually as a test, which is also not successful:

LMS-SI-DI#copy flash:backup-2011-11-29 tftp:

Address or name of remote host []? 172.22.210.205

Destination filename [backup-2011-11-29]?

%Error opening tftp://172.22.210.205/backup-2011-11-29 (Permission denied)

But it is indeed possible to download files manually from the LMS TFTP Server/directory.

In my TFTPboot directory on LMS Server I have only these files:

When I try a Smart-Install with a blank switch connected on my Director, the "imagelist" file is the cause for the failed SI process:

*Mar  1 00:03:21.444: %SMI-6-UPGRD_SUCCESS: Device (IP address: 192.168.1.52) startup-config has upgraded successfully

*Mar  1 00:03:21.460: %SMI-6-UPGRD_STARTED: Device (IP address: 192.168.1.52) image upgrade has started

%Error opening tftp://172.22.210.205/3750e-48poe-imagelist.txt (Timed out)

%Error opening tftp://172.22.210.205/3750e-48poe-imagelist.txt (Timed out)

%Error opening tftp://255.255.255.255/3750e-48poe-imagelist.txt (Timed out)

%Error opening tftp://255.255.255.255/3750e-48poe-imagelist.txt (Timed out)

*Mar  1 00:05:18.238: smi_get_image_array: ERROR : could not download imagelist file: tftp://172.22.210.205/3750e-48poe-imagelist.txt

*Mar  1 00:05:18.238: HSMI_ERR:

!! smi_ibc_download_image : error in getting image array

Seems like the SI process tries to copy a imagelist file to the LMS TFTP Server but is not allowed.

Usually this file is located on the flash as far as I know - what am I missing here?

Thanks

Re: LMS 4.1 - Smart Install generates wrong configuration for DI

Ok this one I could resolve by myself (;

LMS TFTP does not allow to store files, that are not existing in tftpboot directory.

So I had to create the file "3750e-48poe-imagelist.txt" as empty file on the server and then SI worked as expected.

As resumé I have to say: Smart Install Work Center with LMS is not very well engineered until now.

Without deep knowledge about DHCP snooping, LMS TFTP Tweaking a.s.o. it is not possible to get it work...

I still run into some Smart Install issues, like if there is not enough space on flash for another image, the process also fails... lot of investigation is necessary here...

What you see is the common TFTP server behavior sometimes called security.

If you desire to opload files from devices, this can be done using the RCP or SCP facilities.

LMS actually runs an RCP server as a service and an SCP server as a process.

You can set a username password under: Admin > System > System Preferences

I'm not familiar with a smart install.

Cheers,

Michel
