System Intialization

Auto Init

During the first boot or a reboot after the execution of CLI command admin reboot auto-init, if
the user does not intervene to create the BOF file in the manual mode, the system, by default, goes
to auto-init procedure after a "wait" time. The default wait time is 3 seconds. There are two
designated ports used for auto init. These are the front panel ports, port 1 and port 2. Auto init
requires a DHCP server to be configured in the network which should be reachable by the system.
DHCP requests are directed out of one uplink port at a time. All other ports of the system would be
down.
If a DHCP server is present in the network, the system expects to receive an IP address, the default
gateway information, and BOF file path in the response returned by the DHCP server. Upon
receiving these parameters from DHCP server, the system will apply the IP configuration and then
download the BOF file from the path given by the DHCP server. The BOF file is then saved into
the flash and is used for subsequent reboots. The bootstrap image then processes the BOF
parameters in order to boot the system. BOF processing is explained in

The system first attempts to use uplinkA and then uplinkB parameters to receive a successful
response from the DHCP server. If there is no response from the DHCP server on both the uplink
ports, the boot procedure is restarted, during which the user can opt to enter the manual mode or
allow the system to default to auto-init again.
Note: Ethernet management port does not support AutoInit mode. The use of DHCP to obtain the
BOF file from the network and other system parameters is currently not supported on Ethernet
management port.

Out-of-band (OOB) Ethernet Management Port

An Out-of-band Ethernet port can be used to download the TIMOS image file and the
configuration file. In the Autoinit manual mode, if the OOB port is enabled (that is the eth-mgmt-
disable is set to "no"), the OOB port is used to download the TIMOS image file and configuration
file specified in the BOF file, and the system boot is successfully completed. If a system boot fails,
the uplink A and uplink B parameters are used to retrieve the TIMOS image and configuration
files.
