4 Revert from DCB to non-DCB configuration (optional)
One method to revert from a DCB configured switch to a non-DCB configured switch is to delete the current
configuration (startup-config) and follow the steps in section 2. If deleting the current configuration is not an
option, use the following procedure to unconfigure DCB and enable standard flow control.
Note: This is a disruptive operation that requires downtime. The arrays will temporarily lose communication
with each other. Power off all arrays and hosts connected to the SAN before proceeding with these steps.
4.1 Disable DCB
OS10# configure terminal
OS10(config)# no dcbx enable
OS10(config)#
4.2 Disable iSCSI
OS10(config)# no iscsi enable
OS10(config)# no iscsi session-monitoring enable
4.3 Remove DCB policies and apply standard flow control on edge ports
OS10(config)# interface range ethernet 1/1/1-1/1/54
OS10(conf-range-eth1/1/1-1/1/54)# no priority-flow-control
OS10(conf-range-eth1/1/1-1/1/54)# no qos-map traffic-class
OS10(conf-range-eth1/1/1-1/1/54)# no ets
OS10(conf-range-eth1/1/1-1/1/54)# no service-policy output type queuing
<queuing-policy-name>
OS10(conf-range-eth1/1/1-1/1/54)# no service-policy input type network-qos
<policy-map-name>
OS10(conf-range-eth1/1/1-1/1/54)# no switchport trunk allowed vlan <vlan-id>
OS10(conf-range-eth1/1/1-1/1/54)# no switchport mode
OS10(conf-range-eth1/1/1-1/1/54)# switchport mode access
OS10(conf-range-eth1/1/1-1/1/54)# flowcontrol receive on
OS10(conf-range-eth1/1/1-1/1/54)# flowcontrol transmit off
OS10(conf-range-eth1/1/1-1/1/54)# exit
OS10(config)#
