Diagnostic Port (D_Port)

Controlling testing
You can stop and start D_Port testing on a port by using the following respective commands:
• portdporttest - -stop [slot/]port
• portdporttest - -start [slot/]port
Available suboptions to the - --start option are as follows:
• -nframes — Number of frames (in millions)
• -framesize — Size of frame (from 36 to 2112 bytes)
• -time — Test duration (in HH:MM format)
• -pattern — A predefined pattern
• -payload — A user-defined payload
• -fec — Forward error correction (default is off)
• -cr — Credit recovery (default is off)
In addition, the following options are available:
• - -setarg — Allows you to set suboptions between tests or before automatic tests, with the same
options as with the - -start option.
• - -restart — Allows you to use already-set parameters during current tests.
Example test scenarios and output
In addition to the examples shown in“Enabling D_Port” on page 95, other practiical scenarions are
shown below.
Confirming SFP and link status with an HBA
The steps in the following example illustrate how the command bcu diag - -dportenable will fail with
an SFP installed but without a connection to the switch.
1. Confirm the initial port status.
switch:admin> bcu port --list
---------------------------------------------------------------------------
Port# FN Type PWWN/MAC FC Addr/ Media State Spd
Eth dev
---------------------------------------------------------------------------
1/0 - fc 10:00:8c:7c:ff:1c:e9:00 160000 sw Linkup 16G*
0 fc 10:00:8c:7c:ff:1c:e9:00 160000 sw Linkup 16G*
1/1 - fc 10:00:8c:7c:ff:1c:e9:01 -- sw Linkdown ---
1 fc 10:00:8c:7c:ff:1c:e9:01 -- sw Linkdown ---
---------------------------------------------------------------------------
2. Disable the port.
switch:admin> bcu port --disable 1/0
port disabled
3. Remove the connection to the switch and attempt to enable the D_Port.
switch:admin> bcu diag --dportenable 1/0
