Release Notes
Fabric OS v7.3.0a Release Notes v2.0 Page 47 of 55
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.
ISL R_RDY mode is not supported in a base switch with FOS version 7.0 or higher.
WebTools
WebTools since FOS v7.1.0 has a “SupportSave” interface. It only collects, however, information
specifics to WebTools. It does not contain the same information as collected by supportSave initiated
through CLI or Brocade Network Advisor.
When launching WebTools on a computer without Internet access, it could take up to 5 minutes to
complete because the certificate revocation check performed for the WebTools application takes time
to timeout. Users can turn off the certification revocation check on the Java control panel as a
workaround.
FOS v7.3.0 is qualified and supported with Oracle JRE 1.7.0 update 60. When launching Web tools
directly using the browser for FOS 7.3.0, ensure that Oracle JRE update 1.7u60 is installed in that
machine. WebTools can be launched from the local client of Brocade Network Advisor installed on
Windows OS. Launching WebTools from local client of Brocade Network Advisor installed on Linux OS
will fail due to the expiration check with JRE 1.7 update 51. As a workaround for this issue on Linux,
please do the following changes in the Brocade Network Advisor installed computer.
1. Add following lines in <User Home>/.java/deployment/deployment.properties file
deployment.expiration.check.enabled=false
For example, if the user is root then the absolute path of this file is as below
