iSCSI enable

The steps in this section enable iSCSI auto-detection of attached storage arrays and switch auto-
configuration. Dell PS Series and SC Series storage arrays are detected by the switch when iscsi is enabled.
The switch will auto-configure for Jumbo frames with MTU 9216 and flowcontrol receive on, and transmit off
for all the ports. The ports detected to be connected to the storage units are auto-configured as spanning-tree
edge ports withunicast storm control disabled.
OS10(config)# iscsi enable
OS10(config)# iscsi session-monitoring enable
Note: Do not change the LLDP description on the SC Series array. Changing this will disable iSCSI storage
detection and iSCSI auto-configuration.
Note: iSCSI auto-configuration on OS10 switch ports is not supported with QLogic
adapters on SC Series arrays.
2.10

Enable Jumbo frames and flow control (optional)

Note: This step is optional because iSCSI auto-detection and auto-configuration enabled in the previous step
will enable Jumbo frames with MTU 9216 and enable receive flowcontrol on all ports, once PS Series or SC
Series storage ports are detected on the switch.
OS10(config)# interface range ethernet 1/1/1 – 1/1/54
OS10(conf-range-eth1/1/1-1/1/54)# mtu 9216
OS10(conf-range-eth1/1/1-1/1/54)# flowcontrol receive on
OS10(conf-range-eth1/1/1-1/1/54)# flowcontrol transmit off
2.11

Configure spanning tree on edge ports

OS10(conf-range-eth1/1/1-1/1/54)# spanning-tree port type edge
OS10(conf-range-eth1/1/1-1/1/54)# exit
Note: Spanning tree is enabled by default. If there is a need to reconfigure it, use the following command.
OS10(config)# no spanning-tree disable
OS10(config)# exit
2.12

Save configuration

OS10# copy running-configuration startup-configuration
OS10# reload
System configuration has been modified. Save? [yes/no]: yes
Proceed to reboot the system? [confirm yes/no]:yes
