Brocade Fabric OS v7.2.1a Release Notes v1.0

Fabric OS v7.2.1a Release Notes v1.0 Page 29 of 55
Port Mirroring
Port Mirroring is not supported on the Brocade 7800.
Port Statistics
On 16G capable ports, the enc_in (number of encoding errors inside of frames) and enc_out
(number of encoding errors outside of frames) counters will not be updated when a port is operating
at either 10G or 16G speed. This is due to the different encoding scheme used at 10G and 16G
speeds when compared to 8G/4G/2G speeds. Because of this, Fabric Watch alerts and Port Fencing
based on ITW (Invalid Transmission Word) thresholds will not function as these enc_in and enc_out
counters will not be incremented when operating at either 10G or 16G (ITW is computed based on
enc_in and enc_out counters). Also any CLI or GUI that displays enc_in and enc_out counters will
show no incrementing of these counters when a port is operating at either 10G or 16G.
Both enc_in and enc_out counters contain valid information when a Condor3-based port is operating
at speeds other than 10G and 16G.
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
Please note a documentation correction to the Table 3 Certified and Tested Platforms” of the
WebTools Administrator’s Guide supporting Fabric OS v7.2.0. Unlike what is stated in the table,
WebTools is not supported with the Chrome browser with FOS v7.2.0x and FOS v7.2.1. WebTools is
supported with the Chrome browser with FOS v7.2.1a.
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 upto 5 minutes to
complete because the certicate 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.
Launching WebTools with Oracle JRE 1.7.0 update 51 through Brocade Network Advisor is only
supported on version 12.1.5 or later. With JRE 1.7.0 update 51, users could see browser warning
messages that the WebTools application requires unrestricted access or the certificate signing the
application is not recognized. These messages can be ignored. In addition, users must check the
“Enable Java content in the browser” box under the Security tab of Java Control Console to allow
launching WebTools from BNA server clients.
Zoning
Support for up to 2MB zone database in a fabric with only DCX/DCX-4S/DCX8510 systems. The
presence of any other platform in the fabric will limit the maximum zone database to 1MB. Please
note that there is no enforcement by FOS 7.1 or later to restrict users to operate within a zone
database limit - it is the responsibility of the user to not exceed this limit.
