Quick Steps for Automatic Remote Configuration
1 Configure the DHCP server in the network to provide IP address, gateway, and TFTP server addresses
to the OmniSwitch DHCP client.
2 Store the instruction file on the TFTP server.
3 Store the configuration, image, and script files on the primary and/or secondary FTP/SFTP servers.
4 When the OmniSwitch is integrated in to the network as a new device with no vcboot.cfg file in the
working directory, the automatic remote configuration process is initiated.
5 A DHCP client is automatically configured on the OmniSwitch. The OmniSwitch obtains IP address
information, TFTP server address, instruction file name, and location from the DHCP server through the
DHCP client.
6 The OmniSwitch downloads the instruction file from the TFTP server. The instruction file contains the
file names and file locations of the configuration, image, and script files.
7 The OmniSwitch downloads the image files from the FTP/SFTP server if necessary.
8 The OmniSwitch downloads the configuration file from the FTP/SFTP server, if available, and saves it
as the vcboot.cfg file in the /flash/working/ directory. If no script file is downloaded, the switch reboots
applying the downloaded configuration file and the automatic configuration process is complete.
9 The OmniSwitch downloads the script file, if available, from the FTP/SFTP server and runs the
commands in the script file.
Note.
• If the script file is not specified in the instruction file, or if it is not properly downloaded, then the
Remote Configuration Manager software automatically initiates a reload from working no
rollback-timeout command
after firmware or bootup configuration files are downloaded.
• If a write memory command is used in the script file, then it overwrites the vcboot.cfg file. Hence, if
the script file is downloaded along with the bootup configuration file, then the script file must not
contain the write memory command.
• If a vcboot.cfg is already present in the working directory of the switch, Automatic Remote
Configuration Download does not occur.
