To disable D_Port diagnostic mode:
From the Brocade Fibre Channel 16G or 32G switch, issue the following
commands:
# portdisable <port_num>
# portcfgdport ––disable <port_num>
# portenable <port_num>
The D_Port test stops.
Configuring and Running Diagnostics Port on a Cisco
Fibre Channel 16 or 32G Switch
The following example configures and starts a diagnostic test on port 2 of a Cisco
Fibre Channel 9396S or 97xx switch (NX-OS 8.2.1 or later). For more details
about the switch, see the Cisco switch documentation.
Cisco# config t
Cisco# int fc 1/2
Cisco(config-if)# shut
Cisco(config-if)# switchport link-diag
Cisco(config-if)# no shut
Cisco(config-if)# diagnostic start interface fc 1/2 test link-diag
To check the diagnostic test status, type the following command:
Cisco(config-if)# show diagnostic result interface fc1/1 test
link-diag
