 Integrated Routing and TopTalkers (Fabric Mode) are not concurrently supported. To use Integrated
Routing, be sure to disable Fabric Mode TopTalkers prior to configuring EX_Ports first.
Native Connectivity
 FOS-based platforms operating in interopmodes 2 or 3 should never be deployed in a fabric without at
least one M-series switch. FOS switches in interopmode 3 (McDATA Open Fabric Mode) do not support
configuration of zoning without an M-series switch in the fabric. When migrating from M-series to B-
series switches, all B-series switches should be configured to interopmode 0 (Brocade Native mode)
once the last M-series switch has been removed from the fabric.
 M-EOSc switches may exhibit a behavior where they block all attached devices with a reason
indication of “Blocked Temporarily, Internal”. Users that experience this may have power cycled the
M-series switch while it was participating in a fabric with Frame Redirection zoning, a capability used
for FOS-based application or encryption services . If the switch is still participating in the fabric with
Frame Redirection, issue the “cfgsave” command from a Brocade FOS-based switch with the Frame
Redirection zone in its defined zone database. If the M-EOS switch is no longer attached to the fabric
with Frame Redirection zoning, issue the “Config.Zoning.deleteSplZoneSet” command via CLI to the M-
EOS switch.
FCAP
 If VF is enabled on a switch, HTTPS and FCAP certificates should always be imported in the Default
Switch. Certificates imported in a non-Default Switch will not be available after hafailover operation.
 The pkicert (1.06) utility may cause evm errors, so each new switch should be isolated from the fabric
and placed in non-vf mode to install new certificates.
FICON
 Refer to Appendix: Additional Considerations for FICON Environments for details and notes for
deployment in FICON environments.
FL_Port (Loop) Support
 The FC8-48 and FC8-64 blade support attachment of loop devices in the DCX and DCX-4S.
 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, FC4-16 and
FC4-32 blades with no new restrictions.
Port Mirroring
 On the Brocade 5300, the port mirroring feature has a limitation where all port mirror resources must
stay within the same ASIC port group. The resources are the configure mirror port, Source Device, and
Destination Device or ISL, if the Destination Device is located on another switch. The ASIC port groups
are 0-15, 16-31, 32-47, 48-63, and 64-79. The routes will be broken if the port mirror resources are
spread across multiple port groups.
 Port Mirroring is not supported on the Brocade 7800.
