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 requires 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 , fortyGigE 0/52
FTOS(conf-if-range-fo-0/48,fo-0/52)#no dcb-map profile-name
FTOS(conf-if-range-fo-0/48,fo-0/52)#flowcontrol rx on tx off
FTOS(conf-if-range-fo-0/48,fo-0/52)#exit
FTOS(conf)#exit
4.3

Revert to default VLAN ID on switch and arrays

Once DCB is disabled on the switch, the EqualLogic arrays will no longer use the VLAN ID that was
configured when DCB was enabled. The arrays will 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 or native 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".
Note: Host NICS must also be updated with matching VLAN information.
Use the steps below to configure the native VLAN on the switch.
