Ethernet

Click on the

Ethernet

menu item.

iSCSI Port Number

Specifies the port number whereby the iPBridge listens
for iSCSI connections. The port number must be between
1024 and 65535 except for port 860. The default is 3260.

iSCSI

Click on the

iSCSI

menu item.

iSCSI Alias

Provides a human-readable name assigned to the
iPBridge. Aliases may be 1 to 64 characters long and may
contain spaces if spaces are enclosed in quotation
marks. The default is a blank space.

iSNS Login Control

Specifies whether the iPBridge will delegate its access
control/authorization to an iSNS server. Default is
disabled.
Note
iSNS Login Control cannot be used with
Access Control found on the
iSCSI Target
Management
page.

iSNSServer

Specifies whether the IP address of a valid iSNS server
from which the iPBridge will attempt iSCSI initiator
discovery. Setting to 0.0.0.0 disables the iSNS server
lookup. Default is 0.0.0.0.

SpeedWrite

When enabled, improves the performance of WRITE
commands to SCSI devices attached to the iPBridge.

CHAP commands

To find the CHAP commands,

1 Click on the Manual Target Mgt menu item
2 Click on the Target Management page
3 Click on the iSCSI CHAP table entry next to the
iSCSI target you wish to use.

iSCSI CHAP

iSCSI CHAP controls whether CHAP (Challenge
Handshake Authentication Protocol) is used for the iSCSI
protocol. If CHAP is enabled, the target requires the
initiator to negotiate CHAP authentication using CHAP
secrets (passwords). An initiator may reject this
negotiation.

iSCSI Chap Secret

Specifies the incoming and outgoing secrets (passwords)
for iSCSI CHAP sessions. Secrets are case sensitive, 12
to 32 characters (16 for Microsoft iSCSI initiator), and
cannot contain spaces.
In
and
out
secrets must be
different.
An
in
secret is for authentication of the server to the
iPBridge. The iPBridge can store up to 32 in secrets.
An
out
secret is for authentication of the iPBridge to the
server. There is only one out secret per target that cannot
be deleted.

iSCSI Target

Creates or deletes an iSCSI target name. The target
name acts as a suffix to the standard bridge iSCSI-
qualified name. The target name may not exceed 24
characters.
