Release Notes

Fabric OS v7.3.0c Release Notes v1.0 Page 47 of 52
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.
• Flow Monitor does not support flows with defined LUN parameters on ingress ports on 8G platforms.
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.
However, a port may remain in “Port Throttled” state for an extended period of time and may never come
online if it fails to negotiate speed successfully with the neighboring port. Users are advised to check the speed
setting of the neighboring switch port to determine the cause of the speed negotiation failure.
Example Output:
74 9 10 36ed40 id N8 In_Sync FC Disabled (Port
Throttled)
Port Mirroring
• Port Mirroring is not supported on the Brocade 7800.
Virtual Fabrics
• When creating Logical Fabrics that include switches that are not Virtual Fabrics capable, it is possible
to have two Logical Switches with different FIDs in the same fabric connected via a VF incapable
switch. Extra caution should be used to verify the FIDs match for all switches in the same Logical
Fabric.
• A switch with Virtual Fabrics enabled may not participate in a fabric that is using Password Database
distribution or Administrative Domains. The Virtual Fabrics feature must be disabled prior to deploying
in a fabric using these features.
