FEC (-fec)
2. Adapter Configuration2. FC Adapter Configuration13. FEC
From the FC Adapter Configuration menu, select the FEC option. The following
menu options allow you to view, enable, or disable support for FEC on the
selected adapter port:
FEC Configuration Menu
1: Status (shows the FEC status as either Enabled or Disabled)
2: Enable (enables FEC; requires a reboot to take effect)
3: Disable (disables FEC; requires a reboot to take effect)
4: Info (shows the quantity of received correctable and uncorrectable FEC errors)
5: Reset (resets the counters for all FEC correctable and uncorrectable errors from the
reported FEC information)
To enable FEC for the selected adapter port:
1. From the FEC Configuration Menu, select the Enable option.
QConvergeConsole CLI prompts you to confirm that you want to Enable
FEC on all ports of the selected HBA?
2. Respond by either typing 1 for Yes or 2 for No.
3. To confirm that FEC is now enabled, select the Status menu option and
view the change.
4. For the FEC change to take effect, you must reboot the server.
BB Credit Recovery (-bbcr)
2. Adapter Configuration2. FC Adapter Configuration14. BB Credit Recovery
Buffer-to-buffer credit recovery (BB-CR) enables two FC peer ports (N_Port,
F_Port, or E_Port) to periodically send and receive the quantity of receiver ready
(R_RDY) signals transmitted. The BB-CR feature allows the peer port to recover
from possible R_RDY signals lost over a lossy link. BB-CR enables two FC ports
logged in with each other to recover lost buffer-to-buffer credits. These lost credits
can impact throughput, cause link resets, and disrupt traffic flow.
NOTE
The forward error correction (FEC) feature is supported only on Marvell
QLogic 16Gb Fibre Channel adapters—including the QLE269x, QLE267x,
and the QLE8362 in FC mode—if the current adapter port is connected to a
Brocade switch with FEC support. For information on how to enable FEC on
the switch side, refer to documentation from Brocade.
For 32Gb adapters, FEC is enabled by default and cannot be disabled.
