We have some Cisco devices which we want to configure firmware uploads but we are not successful. We can run TFTP uploads but in our environment, TFTP is unstable, hence why we want FTP to function.
We checked NCM logs and TCPDUMP of the transfer but was not able to determine the cause.
Release : 20.2
Component : Spectrum Applications
The device does not support FTP
Spectrum checked the following OID for device FTP support
Enable .vnmrc NCM debugging to check device protocol supportability:
Add the line ncm_debug=true
Restart SS or use CLI command to reload .vnmrc: https://knowledge.broadcom.com/external/article?articleId=190121
Reproduce the issue and check VNM.OUT log for errors.
If device is not supporting, you may see messages like the following:
- this is not a Spectrum issue
- problem must be resolved on the device-side
You can check the snmpset failure reason with the help of wireshark . The error-status and error-index in get_response from the device after snmp_set packet gives the reason for snmp_set request failure . The error-status and error-index may not help fully understand snmp-set request rejection at the device side.
