Hi, If NCM_TFTP_Host attribute is blank, Spectrum uses primary NIC IP as TFTP server.
Initially, Spectrum creates a file named "0xmh" in tftpboot folder and then sends SNMP sets to the device in order to tell it "start a copy config TFTP". Then, Spectrum waits for TFTP transfer to finish and finally adds the file "0xmh" contents to Spectrum Database. So, you'll have to troubleshoot all steps: - Try to telnet to the device and run a manual copy run tftp. - Use wireshark to monitor SNMP sets and TFTP transfer. - While running a host config capture, monitor tftpboot folder to see if file is created and it's growing. I had problems with devices with very large configurations. I needed to increase tftp timeout (in Configuration Manager -> Information -> TFTP Configuration). Other times, after rebooting the router, it started working. Regards. James.
