Release Notes

Fabric OS v7.3.0c Release Notes v1.0 Page 49 of 52
• POST diagnostics for the Brocade 5100 have been modified beginning with FOS v6.3.1b and
v6.4.0 to eliminate an “INIT NOT DONE” error at the end of an ASIC diagnostic port loopback
test. This modification addresses BL-1020 Initialization errors encountered during the POST
portloopbacktest. (Defect 263200)
• It is important to note that the outputs of slotshow –p and chassisShow commands also
display the maximum allowed power consumption per slot. These are absolute maximum
values and should not be confused with the real-time power consumption on 16G blades. The
chassisshow command has a “Power Usage (Watts):” field that shows the actual power
consumed in real-time on 16G blades.
• Class 3 frames that have been trapped to CPU will be discarded in the following scenarios on
DCX/DCX-4S/DCX 8510 during the following conditions:
• HA failover on DCX/DCX-4S/DCX 8510 platforms while running FOS v7.0 or later firmware
• Firmware upgrade from v7.0 to a later release on Brocade 300, 5100, VA-40FC, 5300,
6510
• Firmware upgrade from v7.0.1 to a later release on Brocade 6505
• Firmware upgrade from v7.1.0 to a later release on Brocade 6520
• The QSFP information in the sfpshow output will indicate the ID field as all zeros. This is as
designed.
ras080:FID128:root> sfpshow 5/32
QSFP No: 8 Channel No:0
Identifier: 13 QSFP+
Connector: 12 MPO Parallel Optic
Transceiver: 0000000000000000 16_Gbps id
• It is recommended that for directors with more than 300 E_Ports, the switch be disabled prior
to executing the “switchCfgTrunk” command (used to disable or enable trunking on the
switch).
• During non-disruptive firmware upgrades, E_Ports in R-RDY mode may cause some frame
drops on the E-port links.
• The Brocade Network Advisor seed switch should always have the highest FOS version used in
the fabric.
• For login authentication through RADIUS, Brocade switch should be able to reach RADIUS
servers through TCP authentication port (default 1812) and accounting port (default 1813).
Both of these ports must be kept open in any firewall settings.
• When a firmware upgrade on a Brocade 6510 switch initiated through Brocade Network
Advisor results with “failed to enforce new iptable rules” error message, the switch could be
inaccessible via SSH and/or Telnet. Activating (from console) a new policy with rules of
default active policy will restore access to the switch.
• Firmware downgrade from FOS v7.3.0 with one or more ports enabled with the Flow
Generator feature as a SIM port will be blocked. The SIM ports configuration must first be
disabled.
• Firmware upgrade to FOS v7.3.0 with one or more ports enabled with the Flow Generator
feature as a SIM port will be blocked. The SIM ports configuration must first be disabled.
• FOS v7.3.0 includes a fix for defect 492340 where users may see frame drops on the back-
end edge and core ports with FS8-18 and FX8-24 blades in DCX 8510 chassis. This fix will
only take effect after the affected blades are powered off and on. After the fix takes effect, a
new credit allocation model leads to fewer credits available for long distance ports. If there
