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.
