Enable Data Digest enables or disables support for iSCSI data digest.
Data digest is an ISCSI feature that adds a validity check to iSCSI data
to verify that no corruption has occurred during transmission of the
data. The iSR6152 router supports data digest in its hardware to
maximize performance.
Select the check box to enable this option; clear the check box to
disable it.
CHAP Settings include the following:
Enable CHAP enables or disables CHAP support. Select the check
box to enable this option; clear the check box to disable it.
CHAP Secret lets you define the CHAP secret used for authenticating
an iSCSI client. The box is available only when the Enable CHAP
check box is selected. The CHAP secret can contain any ASCII
characters, and should be at least 16 characters in length.
Statistics
The Statistics page for the selected iSCSI port contains a scrollable table of
parameters and values, as shown in Figure 3-13. The table is divided into two
sections: the upper section contains statistics that are port specific, and the lower
section contains shared statistics (common to all iSCSI ports).
NOTE:
Enabling either the Header Digest or Data Digest slows performance,
especially on 10Gb iSCSI ports.
