Command Mode CONFIGURATION
Usage
Information
iSCSI optimization automatically detects storage arrays and autoconfigures switch ports with the iSCSI
parameters that are received from a connected device. The no version of this command disables iSCSI
autodetection.
Starting from release 10.4.1.1, when you perform a fresh installation of OS10, iSCSI autoconfig is enabled
and flow control receive is set to on. However, when you upgrade from an earlier release to release
10.4.1.1 or later, the existing iSCSI configuration is retained and the flow control receive could be set to on
or off, depending on the iSCSI configuration before upgrade.
Example
OS10(config)# iscsi enable
Supported
Releases
10.3.0E or later
iscsi priority-bits
Resets the priority bitmap that is advertised in iSCSI application TLVs.
Syntax iscsi priority-bits {priority-bitmap}
Parameter priority-bitmap — Enter a bitmap value for the dot1p priority advertised for iSCSI traffic in iSCSI
application TLVs (0x1 to 0xff).
Default 0x10 (dot1p 4)
Command Mode CONFIGURATION
Usage
Information
iSCSI traffic uses dot1p priority 4 in frame headers by default. Use this command to reconfigure the
dot1p-priority bits advertised in iSCSI application TLVs. Enter only one dot1p-bitmap value — setting
more than one bitmap value with this command is not supported. The default dot1p 4 value advertises
only if you enabled PFC pause frames for dot1p 4 traffic using the pfc-cos dot1p-priority
command. The no version of this command resets to the default value.
Example
OS10(config)# iscsi priority-bits 0x20
Supported
Releases
10.3.0E or later
iscsi profile-storage
Configures a port for direct connection to a storage device that is not automatically detected by iSCSI.
Syntax
iscsi profile-storage storage-device-name
Parameter storage-device-name — Enter a user-defined name of a storage array that iSCSI does not
automatically detect.
Default Not configured
Command Mode INTERFACE
Usage
Information
Configure directly attached storage arrays that iSCSI supports if they are not automatically detected. This
command is required for storage devices that do not support LLDP. The no version of this command
disables the connection.
Example
OS10(conf-if-eth1/1/2)# iscsi profile-storage compellant
Supported
Releases
10.3.0E or later
