Release Notes

Fabric OS v7.2.1e Release Notes v1.0 Page 29 of 82
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
other thanother than
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.
• FOS v7.1.0 or later supports setting logical switch context using switch name. As a result, configuring
the same switch names for the logical switches in a physical chassis is not allowed.
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 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.
• FOS v7.2.1e is qualified and supported with Oracle Java version 7 update 76 and Java version 8
update 40. Oracle enforces the latest JRE update to be used to launch WebTools. After JRE expiration
date users will see the message “Your Java version is out of date” when launching WebTools. Users
can either ignore the message by selecting the later option to proceed with launching WebTools, or
install the latest JRE release and then launch WebTools.
• Launching WebTools with JRE 1.7.0 update 76 support begins with the following FOS versions under
defect fix 481199:
• FOS v6.4.3f
• FOS v7.0.2e
• FOS v7.1.1c
• FOS v7.1.2
• FOS v7.2.1
