Release Notes

Fabric OS v7.3.0c Release Notes v1.0 Page 13 of 52
FOS v7.3 introduces firmware sync ability for the firmware on an active CP to be automatically synced to a
standby CP after the standby CP is hot-plugged into a backbone switch chassis. Administrator can configure
this ability on their chassis to enable quick operational replacement of a standby CP.
Rolling Reboot Detection Enhancements
FOS v7.3 enhances the rolling reboot detection feature to detect and stop a rolling reboot in disabled FOS
switch state as a first attempt. This would enable an administrator to capture more diagnostic information.
New external RASLOG for Link Reset
FOS v7.3 adds a new external RASLOG (Cx-1014) for Link Reset due to credit loss for both front-end and back-
end ports.
supportInfoClear Command
FOS v7.3 introduces a new CLI command supportInfoClear to clear a number of statistics counters and logs.
This command can help administrators to quickly reset the counters and logs on behalf of switch vendors in
support scenarios.
Brocade 8510 ICL Scalability Enhancement
FOS v7.3 increases the supported number 8510 chassis connected via ICL in a core-edge topology to twelve
switches.
Miscellaneous Enhancements
trunkShow CLI Enhancement
FOS v7.3 adds to CLI trunkShow (via -swname option) to display the switch name of the neighboring switch
connected on the other end of trunked ports.
fabricShow CLI Enhancement
FOS v7.3 adds to CLI fabricShow (via -version option) to display the firmware version of each switch listed in
the fabricShow output.
portShow and portName CLI Enhancement
FOS v7.3 enhances the CLI portShow and portName to display as port name the host name registered with
FDMI for the host system attached to that port. Administrators must enable the “Display FDMI Host Name”
configuration via the configure CLI.
fspfShow and lsdbShow CLI Enhancement
FOS v7.3 changes fspfShow and lsdbShow CLI output to omit all zero value to be listed in port bitmap values.
Device Probing and Update on ALPA 0xC0 and 0x40
FOS v7.3 enhances FCP probing for devices connected to a port with ALPA 0xC0 and 0x40 to obtain the device
information for NS entry.
For base devices that logged in with ALPA 0xC0 and 0x40, FOS v7.3 provides the ability to update NS entries
when these base devices perform logout. Administrators can turn on this update mode to ensure NS and login
database consistency with “F-port Device Update Mode” option under the “Fabric parameters” section of the
configure CLI. This option can only be changed when a switch is disabled.
NPIV Base Device Logout Enhancements
FOS v7.3 enhances NPIV by allowing NPIV devices remain logged in on a port to a fabric when the base device
on the same port performs a logout. Administrator can configure this feature via the portCfgFlogiLogout CLI.
