Fabric OS v7.2.1 Release Notes v1.0 Page 28 of 49
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.
 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.
Flow Vision
 Users must not specify well known FC addresses, domain controller addresses or CUP Port ID (in FMS
mode) for either the source or the destination device field while defining flows.
 Flow Vision does not support port swap. Users must not create flows on ports that are already
swapped and users must not swap the ports on which the flows are currently defined.
 After a HA reboot, a flow generator flow can be created if the source or the destination port is F-Port.
But traffic will not be initiated. Toggling the port will enforce the restriction again to simulated ports.
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.
 If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors.
Native Connectivity (M-EOS interoperability)
 A switch running FOS v7.0 or later cannot form E-port connectivity with any M-EOS platform.
 Platform running FOS v7.1 or later does not support EX port configuration in Interopmode 2 or
Interopmode 3.
 Device sharing between a switch running FOS v7.1 or later and McDATA fabrics is allowed via
Integrated Routing platforms using FOS v7.0.x (or earlier) firmware.
Port Initialization
Users may observe that a port is in “Port Throttled” state when an F_Port is being initialized. This is mostly an
informational message that is shown in switchshow output indicating systematic initialization of F_Ports.
