Release Notes

Fabric OS v7.3.0c Release Notes v1.0 Page 46 of 52
o Only supports FCoE direct attach.
o Layer2 Ethernet traffic is not supported.
o If an FCoE10-24 blade is inserted into a DCX 8510-8 chassis, it is required to reboot the
chassis or slot poweroff/poweron core blades. A chassis reboot or slot poweroff/poweron
core blades must also be performed if the FCoE10-24 blade is removed and replaced with
another blade type.
FCR and Integrated Routing
• With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs
unique.
• VEX edge to VEX edge device sharing will not be supported.
• The man page and help display of fcrlsanmatrix --display and fcrlsan --show command syntax should
be corrected as below:
fcrlsanmatrix --display -lsan | -fcr | -all
fcrlsan --show -enforce | -speed | -all
•
Forward Error Correction (FEC)
• Though FEC capability is generally supported on Condor3 (16G capable FC) ports when operating at
either 10G or 16G speed, it is not supported with all DWDM links. Hence FEC may need to be disabled
on Condor3 ports when using DWDM links with some vendors by using portCfgFec command. Failure
to disable FEC on these DWDM links may result in link failure during port bring up. Refer to the
Brocade Fabric OS 7.x Compatibility Matrix for supported DWDM equipment and restrictions on FEC
use.
• To connect between a switch and an HBA at 16 Gbps, both sides must be in the same mode (fixed
speed, and FEC on or off) for them to communicate at that rate. If only one port has FEC enabled,
neither port will be able to see the other. If the ports are in dynamic mode, then they may connect, but
not at 16 Gbps.
FICON
• For FICON qualified releases, please refer to the Appendix: Additional Considerations for FICON
Environments section for details and notes on deployment in FICON environments. (This appendix is
only included for releases that have completed FICON qualification).
FL_Port (Loop) Support
• FL_Port is not supported on FC16-32, FC16-48, FC16-64, FC8-32E, FC8-48E, Brocade 6510, Brocade
6505, Brocade 6520, or Brocade 7840.
• The FC8-48 and FC8-64 blade support attachment of loop devices.
• Virtual Fabrics must be enabled on the chassis and loop devices may only be attached to ports on
a 48-port or 64-port blade assigned to a non-Default Logical Switch operating with the default 10-
bit addressing mode (they may not be in the default Logical Switch).
• A maximum of 144 ports may be used for connectivity to loop devices in a single Logical Switch within
a chassis in 10-bit dynamic area mode on DCX-4S.
• A maximum of 112 ports may be used for connectivity to loop devices in a single Logical Switch within
a chassis in 10-bit dynamic area mode on DCX.
• Loop devices continue to be supported when attached to ports on the FC8-16, FC8-32 with no new
restrictions
