Fabric OS v7.1.0a Release Notes v1.0 Page 37 of 41

 The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade

8000 to FOS v7.1 or downgrading from v7.1 is disruptive to the IO through the switch.

 Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.4.1_fcoe1

to FOS v7.0 or later will be non-disruptive to FCoE traffic through FCOE10-24 blades and FC traffic.

 Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.3.x, v6.4.x,

and v6.4.1_fcoe to FOS v7.0 or later will be disruptive to any traffic through the FCOE10-24 blades.

 Connecting Brocade 8000 to an FCR-capable switch with fcrbcast config enabled will cause a storm of

broadcast traffic resulting in termination of iswitchd.

 When rebooting a DCX or DCX-4S with an FCOE10-24 blade, Qlogic CNA and LSAN zoning, the switch

will become very unresponsive for a period of time. This is due to the CNA sending excessive MS

queries to the switch.

 The Brocade 8000 and FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the

Brocade 8000 or FCOE10-24, and you delete a large number of v-ports with HCM, some of the v-ports

may not appear to be deleted. To correct this, disable and re-enable FCoE with the following CLI

commands:

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.

 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.

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 when using active DWDM links. Hence FEC must be

disabled on Condor3 ports when using active DWDM links by using portCfgFec command. Failure to

disable FEC on active DWDM links may result in link failure during port bring up.

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, Brocade 6505

and Brocade 6520.

 The FC8-48 and FC8-64 blade support attachment of loop devices.
