Release Notes

Fabric OS v7.2.0a Release Notes v1.0 Page 36 of 93
When using anonymous ftp, to avoid long delays or failure of simultaneous supportsave
collections when AP blades are present in a director chassis, the number of unlimited
anonymous users for a Windows FTP server should be configured as follows:
Number of anonymous FTP connections = (Number of director chassis) + (Number of
installed Application Blades x 3)
 RASlog message AN-1010 may be seen occasionally indicating “Severe latency bottleneck
detected”. Even though it is a “Warning” message, it is likely to be a false alarm and can be
ignored.
 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 chassishow 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.
