Every time when you modify dhcpd.conf file, DHCP service must be restarted. Issue “killall dhcpd”
command to disable DHCP service and then issue “dhcpd” command to enable DHCP service.
Step 4. Backup a Configuration File
Before preparing a configuration file in TFTP/FTP Server, make sure the device generating the
configuration file is set to “Get IP address from DHCP” assignment. This is because that DHCP
Auto-provisioning is running under DHCP mode, so if the configuration file is uploaded by the
network type other than DHCP mode, the downloaded configuration file has no chance to be equal
to DHCP when provisioning, and it results in MD5 never matching and causing the device to
reboot endless.
In order for your Managed Switch to retrieve the correct configuration image in TFTP/FTP Server,
please make sure the filename of your configuration file is defined exactly the same as the one
specified in in dhcpd.conf. For example, if the configuration image‟s filename specified in
dhcpd.conf is “metafile”, the configuration image filename should be named to “metafile” as well.
Step 5. Place a copy of Firmware and Configuration File in TFTP/FTP
The TFTP/FTP File server should include the following items:
1. Firmware image (This file is provided by the vendor.)
2. Configuration file (This file is generally created by users.)
3. User account for your device (For FTP server only.)
