Managing Automatic Remote Configuration Download
Automatic Remote Configuration Download
Process
The automatic remote configuration process is initialized when an OmniSwitch is integrated in to the
network as a new device or when a firmware and configuration upgrade is required.
If the automatic configuration download process is not performed completely on the switch, manual
intervention is required. For details on troubleshooting techniques under such instances, see
"Troubleshooting" on page 8-24
The detailed process of Automatic Remote Configuration Download performed on the OmniSwitch is as
follows:
1 When the switch is integrated in to the network as a new device with no boot.cfg file, then Automatic
Remote Configuration is performed on the switch.
2 The Remote Configuration Manager on OmniSwitch configures a link aggregate automatically when a
LACP PDU is detected on combo or uplink ports on the switch during Automatic Remote Configuration.
For details, see the following section
3 A DHCP client is automatically configured first on the default VLAN at switch boot up. OmniSwitch
then uses different methods of DHCP client configuration until connection to a DHCP Server is obtained.
For details, see the following section
4 The DHCP client looks for the OXO DHCP server response to provide preference to the desired OXO
DHCP server. For details, see the following section
page 8-19
5 The DHCP client obtains the switch IP address information from the DHCP server.
6 The DHCP client obtains the TFTP server IP address from the DHCP server using Option (66).
7 The DHCP client obtains the instruction file name and location from the DHCP server using Option
(67).
8 SSH access is automatically enabled to allow remote access in case the automatic configuration
process fails.
9 The instruction file with the .alu extension is downloaded from the TFTP server to the /flash/working
directory of the OmniSwitch.
10 If available, the configuration, script, and images files are downloaded from the FTP or SFTP serv-
ers. The password used to connect to the FTP/SFTP servers is same as the username.
11 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
in to the /flash/working directory.
12 If available, the downloaded configuration file is saved as the boot.cfg file in the /flash/working
directory and the switch is rebooted completing the auto configuration process (a reboot occurs only if no
script file is downloaded).
13 If available, commands in the script file are run and the DHCP client configuration is automatically
removed on the default VLAN 1.
