The client searches for option 43 in the DHCP reply. This provides the URL,
which has to be accessed through FTP. For example: ftp://
abcd:xyz@10.0.0.2/test/bof.cfg. If this file is found the client retrieves this
file.
- collating server-name and file-name
If option 43 is not found in the DHCP reply, a URL is formed by using the
tftp-server name and the boot-file retrieved via TFTP. The IP address of the
TFTP server is obtained from DHCP option 66 or the "sname" field of a
DHCP message, and the filename on the TFTP server is obtained from
DHCP option 67 or the "file" field of a DHCP message.
• In manual mode, if the OOB port is enabled (that is, if no eth-mgmt-disable is
configured), the OOB port is used to download the TIMOS image file and
configuration file specified in the BOF, and the system boot is successfully
completed. If a system boot fails, the uplinkA and uplinkB parameters are used
to retrieve the TIMOS image and configuration files.
• On the 7210 SAS-M 24F 2XFP (10GigE) (both standard and ETR variants),
DHCP requests are sent out of ports 1/1/25 and 1/1/26 as part of auto-init. The
system attempts to obtain the system parameters and BOF location by sending
out DHCP requests on the following ports in this order: 1/1/1, 1/1/2, 1/1/25, and
1/1/26. The system sends out the DHCP request on a single port at a specific
time and waits for the DHCP server to respond. If a successful server response
is received, the auto-init process uses the information to boot up the system. If
no response is received from the server within a stipulated time, the system
sends out DHCP requests on the next port in the list based on the preceding
order, looping through all the ports until a successful response is received from
the server, or the user interrupts the boot process.
• On a factory-shipped 7210 SAS-T device, the system attempts the auto-init
process (that is, sends DHCP requests) using the first two 1GE ports (1/1/1 and
1/1/2 on 7210 SAS-T) and the last two 10GE ports (1/1/25 and 1/1/26 on
7210 SAS-T). See System Boot Options for 7210 SAS-Sx 1/10GE,
7210 SAS-S 1/10GE, 7210 SAS-Sx 10/100GE, and 7210 SAS-Mxp in Satellite
Mode and System Boot Options for 7210 SAS-Mxp, 7210 SAS-S 1/10GE,
7210 SAS-Sx 1/10GE, and 7210 SAS-Sx 10/100GE in Standalone Mode
information about ports used for bootup on these platforms.
• On the 7210 SAS-M 24F 2XFP, the 10G MDA cannot be used for auto-init. The
use of DHCP to obtain the BOF is not supported with the 10G MDA.
• When using auto-init with partial BOF configuration, the user has the option to
either stop auto-init by logging in to the node and using the console to run the
admin>auto-init stop command or let auto-init continue.
• The user can intervene to stop auto-init at any time when auto-init is in progress.
The system logs the progress of auto-init. The system emits the LED light until
auto-init is complete or when the user stops the auto-init process.
