We have LMS 4.1 with more than 150 devices.
Config Archive is failed for around 20 device.
11- Cisco VG248 ( Cisco analogue gateway)
7 - Cisco call manager
2 - Wireless Lan controller
For this device- discovery, Inventory Collection ,Fault Discovery, Topology Data Collection ,etc are successfull.
Can you please advice me what could be the reason for this issue
Are you sure that these devices are supported by the LMS ?
I also have a WLC and I know that the software version of the WLC is not supported on my LMS.
I know that it is already a late answer... But I do no like to see a question no answered...
Are you sure that the LMS support the config collection on these devices ?
Check on this link :
If yes, it means that you have a problem for the file transfer... I would suggest to debug like this :
1) Check the credentials (Inventory->Job Browser->Device Credential Verification Jobs, then create a new one)
2) Is it possible to do a tftp from the device to the LMS ? (If the config is done by tftp)
Create a tmp file on /tftpboot on LMS
Copy the startup or running file from the device to the LMS with the name of your tmp file (it is not allowed to create a file on the LMS with TFTP)
3) Do a sniffing of the traffic between the LMS and the device in order to see what happen
