3  Configure Data Center Bridging (DCB) (optional) 
To enable DCB mode on the switch, use the commands in this section.  
Note: Complete the switch configuration steps in section 2 before configuring the switch for DCB mode.   
 
Note: DCB switch configuration is applicable only for environments with DCB-capable SC Series arrays. 
3.1  Disable iSCSI 
OS10# configure terminal 
OS10(config)# no iscsi enable 
OS10(config)# no iscsi session-monitoring enable 
3.2  Disable 802.3x flowcontrol on all ports 
OS10# configure terminal 
OS10(config)# interface range ethernet 1/1/1–1/1/54 
OS10(conf-range-eth1/1/1-1/1/54)# no flowcontrol receive 
OS10(conf-range-eth1/1/1-1/1/54)# no flowcontrol transmit 
OS10(conf-range-eth1/1/1-1/1/54)# exit 
OS10(config)# 
3.3  Enable DCB  
OS10(config)# dcbx enable 
3.4  Create tagged VLAN for all ports and port-channels 
Note: You must supply a VLAN ID. The valid range is 2-4093. 
The following commands configure a single VLAN ID. If desired, multiple VLAN IDs can be created on the 
switch and assigned to ports. 
OS10(config)# interface vlan <vlan-id> 
OS10(conf-if-vl-<vlan-id>)# mtu 9216 
OS10(conf-if-vl-<vlan-id>)# no shutdown 
OS10(conf-if-vl-<vlan-id>)# exit
