Target TCP Port Number – Identifies the TCP port number the router uses
to receive iSCSI target commands. The iSCSI community uses TCP port
number 3260 by default any change to this TCP port number requires a
corresponding change in all iSCSI initiators connecting to this iSCSI target
port. When you change the target TCP port number, you must click Save (at
the bottom of the page) for the change to take effect.
Jumbo Frame – Enables or disables router jumbo frame size as the
maximum transfer unit (MTU). Disabling this option sets the port to support
1500 byte MTU. Enabling this option sets the port to support 9000 bytes
MTU. To change this setting, select Enabled or Disabled from the
drop-down menu. When you change this setting, you must click Save (at the
bottom of the page) for the change to take effect.
Max Burst Length – Enables you to set the iSCSI maximum burst length.
To change this setting, select the desired value (ranging from 512 to
262144 bytes) from the drop-down menu.
Max First Burst Length – Enables you to set the iSCSI maximum first burst
length. To change this setting, select the desired value (ranging from 512 to
262144 bytes) from the drop-down menu.

Enable Header Digest – Enables or disables support for iSCSI header
digest. Header digest is an ISCSI feature that adds a validity check
field to iSCSI PDU headers to verify that no corruption has occurred
during the transmission of the PDU header. The SANbox 6142 router
supports digest in its hardware to maximize performance. When you
change this setting, you must click Save (at the bottom of the page) for
the change to take effect.
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 the
transmission of the data. The SANbox 6142 router supports data
digest in its hardware to maximize performance. When you change this
setting, you must click Save (at the bottom of the page) for the change
to take effect.
