1 Congure an interface or interface range to detect a connected storage device.
interface ethernet node/slot/port:[subport]
interface range ethernet node/slot/port:[subport]-node/slot/port[:subport]
2 Enable the interface to support a storage device that is directly connected to the port and not automatically detected by iSCSI. Use
this command for storage devices that do not support LLDP. In this release, the only valid
storage-device-name value is
Compellant. The switch auto-detects and auto-congures Dell EqualLogic storage arrays directly connected to an interface when
you enable iSCSI optimization.
iscsi profile-storage storage-device-name
3 Congure DCBX to use LLDP to send iSCSI application TLVs with the dot1p priorities for iSCSI trac in INTERFACE mode.
lldp tlv-select dcbxp-appln iscsi
4 Return to CONFIGURATION mode.
exit
5 (Optional) If necessary, re-congure the iSCSI TCP ports and IP addresses of target storage devices in CONFIGURATION mode.
Separate TCP port numbers with a comma (0-65535; default 860 and 3260).
iscsi target port tcp-port1 [tcp-port2, ..., tcp-port16] [ip-address ip-address]
6 Congure the QoS policy applied to the ingress iSCSI ows. Apply the service policy to ingress interfaces in CONFIGURATION mode.
(Optional) Reset the default CoS dot1p priority (default 4) and/or the trusted DCSP value used for iSCSI trac. Assign an internal
qos-group queue (0 to 7) to dot1p (0 to 7) and DSCP (0 to 63) values in POLICY-CLASS-MAP mode.

7 Enable iSCSI monitoring sessions on TCP ports in CONFIGURATION mode.
iscsi session-monitoring enable
8 Set the aging time for the length of iSCSI monitoring sessions in CONFIGURATION mode (5 to 43,200 minutes; default 10).
iscsi aging time [minutes]
9 (Optional) Recongure the dot1p priority bits advertised in iSCSI application TLVs in CONFIGURATION mode. The default bitmap is
0x10 (dot1p 4). The default dot1p 4 value is sent in iSCSI application TLVs only if you enabled the PFC pause for dot1p 4 trac
(
pfc-cos dot1p-priority command).
If you do not congure an iscsi priority-bits dot1p value and you congure a set cos value in Step 6, the set cos value
is sent in iSCSI application TLVs. If you congure neither the
iscsi priority-bits nor the set cos value, the default dot1p 4
is advertised.

10 Enable iSCSI auto-detection and auto-conguration on the switch in CONFIGURATION mode.
