3. Repeat steps 1 and 2 for Port 2 on Switch B.
switchB:admin> portdisable 2
switchB:admin> portcfgdport --disable 2
4. Enable Port 1 on Switch A by using the portEnable command.
switchA:admin> portenable 1
5. Enable Port 2 on Switch B by using the portEnable command.
switchB:admin> portenable 2
Pre-provisioning D_Ports
In a normal scenario, you need to disable a port before enabling static D_Port on the particular port.
This is a disruptive operation and any command or procedure error could cause the wrong port to go
down. To avoid such errors, you can pre-provision the ports that need to be configured as D_Ports.
Any pre-provisioned port does not require to be disabled before configuring it as a D_Port.
1. To add one or more ports to the D_Port provision list, use the portcfgdport --provision -add
[slot/]port_list command.
Switch:admin> portcfgdport --provision -add 7/16
2. To remove one or more ports from the provision list, use the portcfgdport –-provision –delete
[slot/]port_listcommand.
Switch:admin> portcfgdport --provision -delete 4/12
3. To list the ports in the provision list, use the portcfgdport --provision -show command.
Switch:admin> portcfgdport --provision -show
Slot Port D-Port provision
============================
7 16 ON
7 17 ON
7 18 ON
The following example shows that a port is not pre-provisioned:
Switch:admin> portcfgdport –-provision –show 7/20
Slot Port D-Port provision
============================
7 20 OFF
4. To enable D_Port mode on a pre-provisioned port, use the portcfgdport --enable command. You
do not need to disable the port before running this command. However, this command will display
an error message if the particular port is not pre-provisioned using the previous steps.
Switch:admin> portcfgdport --enable 4/10
5. To disable D_Port mode on a pre-provisioned port, use the portcfgdport --disable command.
Switch:admin> portcfgdport -–disable 4/10
Using D_Port between switches and HBAs
When HBAs are used, D_Port mode initiates electrical loopback, optical loopback, and link traffic
diagnostic tests on the link between the HBA and the connected switch port. Results can be viewed
from the switch by means of Fabric OS commands and from the adapter by way of the Brocade
Command Line Utility (BCU) and Brocade Host Connectivity Manager (HCM) during or after the test.
Once in D_Port mode, the adapter port does not participate in fabric operations, log in to a remote
device, or run data traffic.
