Automatic Remote Configuration Download Process

Automatic Remote Configuration Download
Process
The automatic remote configuration process is initialized when an OmniSwitch is integrated into the
network as a new device or when a firmware and configuration upgrade is required.
If the automatic configuration download process is terminated midway, or if it is not performed
completely on the switch, manual intervention is required. For details on troubleshooting techniques under
such instances, see -
The detailed process of Automatic Remote Configuration Download performed on the OmniSwitch is as
follows:
1
When the switch is integrated into the network as a new device with no boot.cfg file, then Automatic
Remote Configuration is performed on the switch.
2
A DHCP client is automatically configured on the switch at boot up.
3
The switch must have at least one port with connectivity to the DHCP server through default VLAN 1.
4
The DHCP client obtains the switch IP address information from DHCP server.
5
The DHCP client obtains the TFTP server IP address from the DHCP server using option 66.
6
The DHCP client obtains the instruction file name and location from the DHCP server using option 67.
7
SSH access is automatically enabled to allow remote access in case the auto configuration process fails.
8
The instruction file with the .alu extension is downloaded from the TFTP server to the /flash/working
directory of the OmniSwitch.
9
If available, the configuration, script, and images files are downloaded from the FTP or SFTP servers.
The password used to connect to the FTP/SFTP servers is same as the username.
10
If available, the switch compares the firmware version available on the switch with the firmware
version in the instruction file. If the firmware versions are different, then the new firmware is downloaded
into the /flash/working directory.
11
If available, the downloaded configuration file is saved as the boot.cfg file in the /flash/working direc-
tory and the switch is rebooted completing the auto configuration process (a reboot occurs only if no script
file is downloaded).
12
If available, commands in the script file are run and the DHCP client configuration is automatically
removed on the default VLAN 1.
