10–iSCSI Protocol
iSCSI Boot
166 83840-546-00 D
Table 10-1 lists parameters for both IPv4 and IPv6. Parameters specific to either
IPv4 or IPv6 are noted.
NOTE
Availability of IPv6 iSCSI boot is platform/device dependent.
Table 10-1. 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 Configu-
ration 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 sec-
onds, 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.
