switch:admin>fcoe –disable slot/port
switch:admin>fcoe --enable slot/port
When a FCOE10-24 blade is powered off during configuration replay, the interface specific
configuration won't get applied. Later when FCOE10-24 blade is powered on, all physical interfaces
will come up with default configurations. User can execute ―copy startup-config running-config‖
command to apply the new configuration after powering on the FCOE10-24 blade.
When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN.
User has to reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN.

FCR and Integrated Routing

With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs
unique.
When using FC Routing in a backbone to edge configuration with an Mi10K in the edge fabric, users
may experience slow throughput for hosts attached to the Mi10K. Users may encounter this following
a bounced IFL connection between the backbone and edge fabric. This slowdown can be resolved by
disabling/enabling the Mi10K ports for the hosts that are impacted.
Mi10K Directors operating with firmware prior to M-EOSn v9.9.5 may experience repeated system
faults when attached as an FCR edge switch to a Brocade 7800 EX Port. To avoid this, ensure that the
Mi10K is operating with M-EOSn v9.9.5 or later when in an edge fabric that will be attached to a
Brocade 7800 FCR Backbone.
VEX edge to VEX edge device sharing will not be supported.
To allow Hot Code Load on Brocade 5100 when using Integrated Routing, the edge switch connected
to the 5100 must be running Fabric OS v6.1 or later code.

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, FC8-32E, FC8-48E, Brocade 6510, and Brocade
6505.
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

ICLs on DCX/DCX-4S

If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the 16-
link license will report enc_out errors. The errors are harmless, but will continue to increment. These
errors will not be reported if a DCX with a 16-link license is connected to a DCX-4S with only 8-link ICL
ports.
