Reverting 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, then use the following procedure to unconfigure DCB and enable standard
flow control.
Note: This is a disruptive operation that will require down time. 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

FTOS#configure
FTOS(conf)#no dcb enable
FTOS(conf)#exit
4.2

Remove DCB policies and apply standard flow control

FTOS#configure
FTOS(conf)#interface range tengigabitethernet 0/0 - 47
FTOS(conf-if-range-te-0/0-47)#no dcb-map profile-name
FTOS(conf-if-range-te-0/0-47)#flowcontrol rx on tx off
FTOS(conf-if-range-te-0/0-47)#exit
FTOS(conf)#interface range fortyGigE 0/48 - 60
FTOS(conf-if-range-fo-0/48-60)#no dcb-map profile-name
FTOS(conf-if-range-fo-0/48-60)#flowcontrol rx on tx off
FTOS(conf-if-range-fo-0/48-60)#exit
4.3

Revert to default VLAN ID on switch and arrays

Once DCB is disabled on the switch, host ports and the EqualLogic arrays will no longer use the VLAN ID
that was configured when DCB was enabled. The arrays revert to the default or native VLAN. Therefore, a
valid VLAN must be configured for all host servers, switches, and EqualLogic array members. A valid VLAN
can use the default VLAN ID (typically 0 or 1) or a specific VLAN can be configured (for example, VLAN
100). If a non-default VLAN is configured, then any ports connected to the arrays must be configured as
"untagged".
