Dell EMC recommended switch configuration 
 
 
10 Dell EMC Networking S4148-ON and S4128-ON Switch Configuration Guide for Dell EMC SC Series SANs | SCG3704 
2.9  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
®
 QLE4062 network 
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
