Configuring iSCSI Boot Parameters
Configure the Broadcom iSCSI boot software for either static or dynamic configuration. Refer toTable 35 for
configuration options available from the General Parameters menu. Table 35 lists parameters for both IPv4 and
IPv6. Parameters specific to either IPv4 or IPv6 are noted.
Table 35: Configuration Options
Option Description
TCP/IP parameters via DHCP This option is specific to IPv4. Controls whether the iSCSI boot host
software acquires the IP address information using DHCP (Enabled) or
use a static IP configuration (Disabled).
IP Autoconfiguration This option is specific to IPv6. Controls whether the iSCSI boot host
software will configure a stateless link-local address and/or stateful
address if DHCPv6 is present and used (Enabled). Router Solicit
packets are sent out up to three times with 4 second intervals in
between each retry. Or use a static IP configuration (Disabled).
iSCSI parameters via DHCP Controls whether the iSCSI boot host software acquires its iSCSI target
parameters using DHCP (Enabled) or through a static configuration
(Disabled). The static information is entered through the iSCSI Initiator
Parameters Configuration screen.
CHAP Authentication Controls whether the iSCSI boot host software uses CHAP
authentication when connecting to the iSCSI target. If CHAP
Authentication is enabled, the CHAP ID and CHAP Secret are entered
through the iSCSI Initiator Parameters Configuration screen.
DHCP Vendor ID Controls how the iSCSI boot host software interprets the Vendor Class
ID field used during DHCP. If the Vendor Class ID field in the DHCP
Offer packet matches the value in the field, the iSCSI boot host software
looks into the DHCP Option 43 fields for the required iSCSI boot
extensions. If DHCP is disabled, this value does not need to be set.
Link Up Delay Time Controls how long the iSCSI boot host software waits, in seconds, after
an Ethernet link is established before sending any data over the
network. The valid values are 0 to 255. As an example, a user may need
to set a value for this option if a network protocol, such as Spanning
Tree, is enabled on the switch interface to the client system.
Use TCP Timestamp Controls if the TCP Timestamp option is enabled or disabled.
Target as First HDD Allows specifying that the iSCSI target drive will appear as the first hard
drive in the system.
LUN Busy Retry Count Controls the number of connection retries the iSCSI Boot initiator will
attempt if the iSCSI target LUN is busy.
IP Version This option specific to IPv6. Toggles between the IPv4 or IPv6 protocol.
All IP settings will be lost when switching from one protocol version to
another.
