Disabling D_Port in static mode
Use this procedure to disable a D_Port diagnostics session in static mode, as configured in "Enabling D_Port in static mode."
NOTE
"Port 1" and "Port 2" simply represent corresponding peer ports at opposite ends of the link to be tested.
1. Disable Port 1 on Switch A.
switchA:admin> portdisable 1
2. Disable the D_Port functionality in static mode on Port 1 on Switch A.
switchA:admin> portcfgdport --disable 1
3. Repeat Steps 1 and Step 2 for Port 2 on Switch B.
switchB:admin> portdisable 2
switchB:admin> portcfgdport --disable 2
4. Reenable Port 1 on Switch A.
switchA:admin> portenable 1
5. Reenable Port 2 on Switch B.
switchB:admin> portenable 2
Disabling D_Port globally
You can prevent D_Port testing from running regardless of the configuration at the other end of the link.
1. Enter interface subtype configuration mode.
2. Enter the fabric dport mode none command.
Using D_Port in dynamic mode
Enabling dynamic D_Port switch-wide configuration forces the ports on that switch or chassis to respond to D_Port requests from the
other end of the connection. It basically responds to a remote port request to change its mode to D_Port mode, and run diagnostic tests
automatically. For more information on enabling dynamic D_Port mode for all ports in a switch or chassis, refer to "D_Port configuration
mode and testing" in this chapter.
Preprovisioning D_Ports
In a normal scenario, you must disable a port before configuring it as a static D_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 preprovision a port that needs to be configured as
a D_Port. Any preprovisioned port does not require to be disabled before being configured as a D_Port.
1. To add one or more ports to the D_Port provision list, use the portcfgdport --provision -add [-dwdm] [
slot /] port_list command.
If the -dwdm option is specified, the ports in the provision list are provisioned for D_Ports over links with DWDM or CWDM.
With the preprovisioning of D_Ports, links with DWDM or CWDM can support dynamic D_Port testing and on-demand D_Port
testing.
