Optionally Licensed Software
Fabric OS v7.2 includes all basic switch and fabric support software, as well as optionally licensed software
that is enabled via license keys.
Optionally licensed features include:
Brocade Ports on Demand—Allows
customers to instantly scale the fabric by provisioning additional ports via
Demand
license key upgrade. (Applies to select models of switches).
Brocade Extended Fabrics—Provides
greater than 10km of switched fabric connectivity at full bandwidth over
Fabrics
long distances (depending on platform this can be up to 3000km).
Note:
If a port on 16G FC blades or a 16G switch is configured to operate at 10G speed, Extended fabrics
license is not needed to enable long distance connectivity on that port.
Brocade ISL Trunking—
Trunking Provides the ability to aggregate multiple physical links into one logical link for
enhanced network performance and fault tolerance. Also includes Access Gateway ISL Trunking on those
products that support Access Gateway deployment.
Brocade Advanced Performance Monitoring—Enables
performance monitoring of networked storage resources.
Monitoring
This license includes the Top Talkers feature.
Brocade Fabric Watch — Monitors mission-critical switch operations. Fabric Watch includes Port Fencing
capabilities.
Brocade Fabric Vision – Enables MAPS (Monitoring and Alerting Policy Suite), Flow Vision, and D_Port to nonBrocade devices. MAPS enables rules based monitoring and alerting capabilities, provides comprehensive
dashboards to quickly troubleshoot problems in Brocade SAN environments. Flow Vision enables host to LUN
flow monitoring, application flow mirroring for offline capture and deeper analysis, and test traffic flow
generation function for SAN infrastructure validation. D_Port to non-Brocade devices allows extensive
diagnostic testing of links to devices other than Brocade switches and adapters. (Functionality requires
support by attached device, availability TBD).
Fabric Vision license also enables Fabric Watch and Advanced Performance Monitoring functionalities without
requiring Brocade Fabric Watch or Brocade Advanced Performance Monitoring license (with FOS v7.2 and later
only).
Note:
If installed on a switch operating with FOS v7.1.x, the Fabric Vision license will be displayed as “Fabric
Insight”. If installed on a switch operating with FOS v7.0.x or earlier, the Fabric Vision license will be
displayed as “Unknown”. Fabric Vision features are not supported under FOS v7.1.x or earlier.

FICON Management Server—
Server Also known as “CUP” (Control Unit Port), enables host-control of switches in
Mainframe environments.
Enhanced Group Management — This license enables full management of devices in a data center fabric with
deeper element management functionality and greater management task aggregation throughout the
environment. This license is used in conjunction with Brocade Network Advisor application software and is
applicable to all FC platforms supported by FOS v7.0 or later.
Note: This capability is enabled by default on all Gen 5 65XX model switches and DCX 8510 platforms,
and on DCX and DCX-4S platforms that are running Fabric OS v7.0.0 or later. Gen 5 embedded
switches receive this capability by default with FOS v7.2.1 and later. Individual upgrade is required
when upgrading directly to FOS v7.2.1 on Gen 5 embedded switches. Subsequent group operations on
Gen 5 embedded switches including group upgrade are supported..

Adaptive Networking with QoS—Adaptive
Networking provides a rich framework of capability allowing a user to
QoS
ensure high priority connections obtain the bandwidth necessary for optimum performance, even in congested
environments. The QoS SID/DID Prioritization and Ingress Rate Limiting features are the first components of
this license option, and are fully available on all 8Gb and 16Gb platforms.
Note :
With FOS v7.2, the Adaptive Networking license has become part of the base FOS firmware, and
features under this license no longer require the license to be installed. Customers that wish to have
these capabilities without purchasing the license are required to upgrade to FOS v7.2 or later.
Brocade 6520 does not require the Adaptive Networking with QoS license to enable the capabilities
associated with this license. These capabilities are included by default on the Brocade 6520.
Server Application Optimization — When deployed with Brocade Server Adapters, this license optimizes overall
application performance for physical servers and virtual machines by extending virtual channels to the server
infrastructure. Application specific traffic flows can be configured, prioritized, and optimized throughout the
entire data center infrastructure. This license is not supported on the Brocade 8000.
Note :
With FOS v7.2, Server Application Optimization license has become part of the base FOS firmware,
and features under this license no longer require the license to be installed. Customers that wish to
have these capabilities without purchasing the license are required to upgrade to FOS v7.2 or later.
Brocade 6520 does not require the SAO license to enable the capabilities associated with this license.
These capabilities are included by default on the Brocade 6520.
Integrated Routing—
Routing This license allows any port in a DCX 8510-8, DCX 8510-4, Brocade 6510, Brocade 6520,
DCX-4S, DCX, 5300, 5100, 7800, or Brocade Encryption Switch to be configured as an Ex_port or VEx_port (on
some platforms) supporting Fibre Channel Routing. This eliminates the need to add an FR4-18i blade or use
the 7500 for FCR purposes, and also provides double or quadruple the bandwidth for each FCR connection
(when connected to another 8Gb or 16Gb-capable port). .
Encryption Performance Upgrade — This license provides additional encryption processing power. For the
Brocade Encryption Switch or a DCX/DCX-4S/DCX 8510-8/DCX 8510-4, the Encryption Performance License
can be installed to enable full encryption processing power on the BES or on all FS8-18 blades installed in a
DCX/DCX-4S/DCX 8510-8/DCX 8510-4 chassis.
DataFort Compatibility — This license is required on the Brocade Encryption Switch or DCX/DCX-4S/DCX 85108/DCX 8510-4 with FS8-18 blade(s) to read and decrypt NetApp DataFort-encrypted disk and tape LUNs.
DataFort Compatibility License is also required on the Brocade Encryption Switch or DCX/DCX-4S/DCX 85108/DCX 8510-4 Backbone with FS8-18 Encryption Blade(s) installed to write and encrypt the disk and tape
LUNs in NetApp DataFort Mode (Metadata and Encryption Algorithm) so that DataFort can read and decrypt
these LUNs. DataFort Mode tape encryption and compression is supported beginning with the FOS v6.2.0
release on DCX platforms. Availability of the DataFort Compatibility license is limited; contact your vendor for
details.
Advanced Extension – This license enables two advanced extension features: FCIP Trunking and Adaptive Rate
Limiting. The FCIP Trunking feature allows multiple IP source and destination address pairs (defined as FCIP
Circuits) via multiple 1GbE or 10GbE interfaces to provide a high bandwidth FCIP tunnel and failover resiliency.
In addition, each FCIP circuit supports four QoS classes (Class-F, High, Medium and Low Priority), each as a
TCP connection. The Adaptive Rate Limiting feature provides a minimum bandwidth guarantee for each tunnel
with full utilization of the available network bandwidth without impacting throughput performance under high
traffic load. This license is available on the 7800 and the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 for the FX824 on an individual slot basis.

• Enables 10G FC capability on Brocade 6510, Brocade 6520.
This license is available on the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 on an individual slot basis.
Advanced FICON Acceleration – This licensed feature uses specialized data management techniques and
automated intelligence to accelerate FICON tape read and write and IBM Global Mirror data replication
operations over distance, while maintaining the integrity of command and acknowledgement sequences. This
license is available on the 7800 and the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 for the FX8-24 on an
individual slot basis.
7800 Port Upgrade – This license allows a Brocade 7800 to enable 16 FC ports (instead of the base four
ports) and six GbE ports (instead of the base two ports). This license is also required to enable additional FCIP
tunnels and also for advanced capabilities like tape read/write pipelining.
ICL 1616-link, or Inter Chassis Links -- This license provides dedicated high-bandwidth links between two Brocade
DCX chassis, without consuming valuable front-end 8Gb ports. Each chassis must have the 16-link ICL license
installed in order to enable the full 16-link ICL connections. (Available on the DCX only.)
ICL 88-Link – This license activates all eight links on ICL ports on a DCX-4S chassis or half of the ICL bandwidth
for each ICL port on the DCX platform by enabling only eight links out of the sixteen links available. This allows
users to purchase half the bandwidth of DCX ICL ports initially and upgrade with an additional 8-link license to
utilize the full ICL bandwidth at a later time. This license is also useful for environments that wish to create ICL
connections between a DCX and a DCX-4S, the latter of which cannot support more than 8 links on an ICL port.
Available on the DCX-4S and DCX platforms only.
ICL POD License – This license activates ICL ports on core blades of DCX 8510 platforms. An ICL 1st POD
license only enables half of the ICL ports on CR16-8 core blades of DCX 8510-8 or all of the ICL ports on
CR16-4 core blades on DCX 8510-4. An ICL 2nd POD license enables all ICL ports on CR16-8 core blades on a
DCX 8510-8 platform. (The ICL 2nd POD license does not apply to the DCX 8510-4.)
Enterprise ICL (EICL) License
License – The EICL license is required on a Brocade DCX 8510 chassis when that chassis
is connected to four or more Brocade DCX 8510 chassis via ICLs either as ISLs or IFLs.
Note that this license requirement does not depend upon the total number of DCX 8510 chassis that exist in a
fabric, but only on the number of other chassis connected to a DCX 8510 via ICLs. This license is
recognized/displayed when operating with FOS v7.0.1 but enforced with FOS v7.1.0 or later.
Note: The EICL license supports a maximum of nine DCX 8510 chassis connected in a full mesh
topology or up to ten DCX 8510 chassis connected in a core-edge topology. Refer to the Brocade SAN
Scalability Guidelines document for additional information.

FOS Migration Considerations
This section contains important details to consider before migrating to or from this FOS release.

FOS Upgrade and Downgrade Special Considerations
DCX/DCX-4S units running any FOS v7.1.x or FOS v7.2.0x can be non-disruptively upgraded to FOS v7.2.1e.
This upgrade is non-disruptive to both FC and FCoE traffic (when using FCOE10-24 blades).
Any firmware activation on Brocade 7800, or DCX, DCX-4S, DCX 8510-8, DCX 8510-4 with FX8-24 will
disrupt I/O traffic on the FCIP links.
For FCIP, the best practice is to always operate the switch or blade at both ends of the tunnel with the same
level of Fabric OS, down to the maintenance release. Fabric OS upgrades should be done on both ends of the
FCIP tunnel concurrently.
Note:
To achieve non-disruptive firmware upgrade on 5431, 6547 and M6505 embedded switches to FOS
v7.2.1e please follow the instructions given below:
5431:
5431
Upgrade 5431 from FOS v7.0.1_hut to FOS v7.0.1_hut1 before non-disruptively upgrading it to FOS
v7.2.1e.
6547:
6547
Upgrade 6547 from FOS v7.0.0_pha3 to FOS v7.0.0_pha4 before non-disruptively upgrading it to FOS
v7.2.1e.
M6505:
M6505
Upgrade M6505 from FOS v7.0.1_ sh to FOS v7.0.1_sh1 before non-disruptively upgrading it to FOS
v7.2.1e.
Disruptive upgrades to Fabric OS v7.2.1e are allowed and supported from FOS v7.0.x (up to a two-level
migration) using the optional “-s” parameter with the firmwaredownload command.
If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node
at a time before downloading on another node.

Recommended Migration Paths to FOS v7.2.1e

For SAN Management, Network Advisor 12.1.4 is available in three editions:

•

Network Advisor Professional:
Professional a fabric management application that is ideally suited for small-size
businesses that need a lightweight management product to manage their smaller fabrics. It manages
one FOS fabric at a time and up to 1,000 switch ports. It provides support for Brocade FC switches,
Brocade HBAs / CNAs, and Fibre Channel over Ethernet (FCoE) switches.

•

Network Advisor Professional Plus:
Plus a SAN management application designed for medium-size
businesses or departmental SANs for managing up to thirty-six physical or virtual fabrics (FOS) and up
to 2,560 switch ports. It supports Brocade backbone and director products (DCX 8510-4/DCX-4S,
48Ks, etc.), FC switches, Fibre Channel Over IP (FCIP) switches, Fibre Channel Routing (FCR) switches/
Integrated Routing (IR) capabilities, Fibre Channel over Ethernet (FCoE) / DCB switches, and Brocade
HBAs / CNAs.

•

Network Advisor Enterprise:
Enterprise: a management application designed for enterprise-class SANs for
managing up to thirty-six physical or virtual fabrics and up to 9,000 switch ports. Network Advisor SAN
Enterprise supports all the hardware platforms and features that Network Advisor Professional Plus
supports, and adds support for the Brocade DCX Backbone (DCX 8510-8/DCX) and Fiber Connectivity
(FICON) capabilities.

More details about Network Advisor’s new enhancements can be found in the Network Advisor 12.1.4 Release
Notes, Network Advisor 12.1.4 User Guide, and Network Advisor 12.1.4 Installation, Migration, & Transition
Guides.
Note:
Brocade Network Advisor 12.1.4 or later is required to manage switches running FOS 7.2.1 or later.
The Brocade Network Advisor seed switch should always have the highest FOS version used in the fabric.

WebTools Compatibility
FOS v7.2.1e is qualified and supported with Oracle Java version 7 update 76 and Java version 8 update
40. Launching WebTools with Oracle JRE 1.7u45 through Brocade Network Advisor is supported on 12.1.5.

Fabric OS v7.2.1e Release Notes v1.0

Page 13 of 82

Brocade Network Advisor 12.1.6 supports launching WebTools with JRE 1.7u45, JRE 1.7u51[Windows],
and JRE 1.7u67 [Linux].

SMI Compatibility
•

It is important to note that host SMI-S agents cannot be used to manage switches running FOS v7.2.
If users want to manage a switch running FOS v7.2 using SMI-S interface, they must use Brocade
Network Advisor’s integrated SMI agent.

Fabric OS Compatibility
The following table lists the earliest versions of Brocade software supported in this release, that is, the earliest
supported software versions that interoperate. Brocade recommends using the latest software versions to get
the greatest benefit from the SAN.
To ensure that a configuration is fully supported, always check the appropriate SAN, storage or blade server
product support page to verify support of specific code levels on specific switch platforms prior to installing on
your switch. Use only FOS versions that are supported by the provider.

When routing to an M-EOS edge fabric using frame redirection, the M-EOS fabric must have a FOS-based product in
order to configure the frame redirection zone information in the edge fabric.

When directly attached to a Host or Target that is part of an encryption flow.

These platforms may not be directly attached to hosts or targets for encryption flows.

McDATA 1620 and 2640 SANRouters should not be used with FOS-based routing (FCR) for connections to the same
edge fabric.

FA4-18 is not supported in a DCX/DCX-4S that is running FOS v7.0 or later

If operating with FOS v6.2.2e or earlier,
earlier Adaptive Networking QoS must be disabled when connecting to 16G FC
platform. Otherwise, ISL will segment.

Connectivity to FC SAN is established via VDX6730 connected to FCR running FOS v7.0.1 or later. FCR platforms
supported include 5100, VA-40FC, 5300, 7800, DCX, DCX-4S, DCX 8510-8, DCX 8510-4, 6510, 6520 (requires FOS
v7.1 or later). For higher FCR backbone scalability (refer to separate “Brocade SAN Scalability Guidelines”
documentation for details), please use 5300, 6520, DCX, DCX-4S, DCX 8510-8, DCX 8510-4.

FR4-18i and FC10-6 are not supported on DCX/DCX-4S on FOS v7.1 or later.

Brocade 8000 is not supported with FOS v7.2 or later.

Represents the earliest major FOS version. These embedded platforms running respective dedicated FOS versions
can also interoperate with FOS v7.2.

Zoning Compatibility Note:
Note
Users are recommended to upgrade to the following versions of firmware when interoperating with a switch
running FOS v7.0 or later in the same layer 2 fabric to overcome some of the zoning operations restrictions
that otherwise exist:

Main code level
FOS v6.2
FOS v6.3
FOS v6.4

Patch code levels with full zoning
compatibility
FOS v6.2.2d or later
FOS v6.3.2a or later
FOS v6.4.1 or later

If there are switches running FOS versions lower than the above listed patch levels in the same fabric as a
switch with FOS v7.0 or later, then cfgsave and cfgenable operations initiated from these switches will fail if
the zoning database is greater than 128KB. In such scenarios zoning operations such as cfgsave/cfgenable
can still be performed successfully if initiated from a switch running FOS v7.0 or later.

power supplies is incorrectly set to zero, which will prevent Fabric Watch from generating notifications when the
switch enters the marginal state due to missing power supplies

Scalability
All scalability limits are subject to change. Limits may be increased once further testing has been completed,
even after the release of Fabric OS. For current scalability limits for Fabric OS, refer to the Brocade Scalability
Guidelines document, available under the Technology and Architecture Resources section at
http://www.brocade.com/compatibility

Other Important Notes and Recommendations
Adaptive Networking/Flow-Based QoS Prioritization
•

Any 8G or 4G FC platform running FOS v6.2.2e or lower version of firmware cannot form an E-port
with a 16G FC platform when Adaptive Networking QoS is enabled at both ends of the ISL. Users must
disable QoS at either end of the ISL in order to successfully form an E-port under this condition.
Users can disable QoS via portcfgQos --disable command. Please consult Fabric OS Command
Reference manual for details related to portcfgQoS command.

•

When using QoS in a fabric with 4G ports or switches, FOS v6.2.2 or later must be installed on all 4G
products in order to pass QoS info. E_Ports from the DCX to other switches must come up AFTER
6.2.2 is running on those switches.

•

When FOS is upgraded from v7.1.x to v7.2.0 or later:

•

If the Adaptive Networking license was NOT installed in v7.1.x, all ports will have QOS disabled
following the firmware upgrade and links will come up in normal mode.

•

If the Adaptive Networking license was installed in v7.1.x, there will be no change in port QOS
mode following the upgrade.

If the remote port supports QOS and QOS is not explicitly disabled on the local or
remote port, the link will come up in QOS mode.

Otherwise, the link will come up in normal mode.

Fabric OS v7.2.1e Release Notes v1.0

Page 22 of 82

•

If FOS v7.2 or later is factory installed (or net installed), Adaptive Networking features are always
available. This matches the behavior of the Brocade 6520 and all products shipping with prior
versions of FOS and with the Adaptive Networking license factory installed.

•

Ports will come up in AE mode by default

•

If the remote port supports QOS and is not explicitly disabled, the link will come up in QOS
mode. Otherwise, the link will come up in normal mode.

Access Gateway
•

Users who want to utilize Access Gateway’s Device-based mapping feature in the ESX environments
are encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices.
Please follow these instructions to access this technote:
•

•

Go to Documentation > Tech Notes.

•

Look for the Tech Note on Access Gateway Device-Based Mapping in VMware ESX Server.

Brocade HBA/Adapter Compatibility
•

Brocade HBA/Adapter should be using driver version 2.3.0.2 or later when attached to 16G ports on
Brocade switches.

D_Port
•

FOS v7.0.0a and later support the execution of D_Port tests concurrently on up to eight ports on the
switch.

•

Support of D_Port is extended to R_RDY flow control mode. The R_RDY mode is useful for active
DWDM links that do not work in VC_RDY or EXT_VC_RDY flow control modes.

•

A new sub-option “-dwdm” is added to “portcfgdport --enable” CLI to configure D_Port over active
DWDM links. The “-dwdm” option will not execute the optical loopback test while performing D_Port
tests as the active DWDM links do not provide necessary support to run optical loopback tests.

Edge Hold Time
•

Edge Hold Time (EHT) default settings for FOS v7.x have changed from those in some FOS v6.4.x
releases. The following table shows the Default EHT value based on different FOS release levels
originally installed at the factory:

Factory Installed Version of FOS

Default EHT Value

FOS v7.X

220 ms

FOS v6.4.3x

500 ms

FOS v6.4.2x

FOS v6.4.1x

FOS v6.4.0x

500 ms

Any version prior to FOS v6.4.0

500 ms

Fabric OS v7.2.1e Release Notes v1.0

Page 23 of 82

Gen 5 platforms and blades are capable of setting an EHT value on an individual port basis. On 8G
platforms EHT is set on an ASIC-wide basis, meaning all ports on a common ASIC will have the same
EHT setting. Extra care should be given when configuring EHT on 8G platforms or Gen 5 platforms
with 8G blades to ensure E_Ports are configured with an appropriate Hold Time setting.

When using Virtual Fabrics and creating a new Logical Switch when running FOS v7.1.0 or later, the
default EHT setting for the new Logical Switch will be the FOS default value of 220ms. However, with
FOS v7.1.0 and later, each Logical Switch can be configured with a unique EHT setting that is
independent of other Logical Switches and the Default Switch. Any Gen 5 ports (Condor3 based)
assigned to that Logical Switch will be configured with that Logical Switch’s EHT setting. Any 8G ports
(Condor2 based) will continue to share the EHT value configured for the Default Switch.

For more information on EHT behaviors and recommendations, refer to the Brocade SAN Fabric
Resiliency Best Practices v2.0 document available on www.brocade.com.

•

SafeNet’s KeySecure hosting NetApp’s LKM (SSKM) is supported for data encryption operations with
SSKM operating in PVM mode.Please see SSKM documentation for operating in PVM mode for details.
Operation in HVM mode is not supported
• RASlog SPC-3005 with error 34 may be seen if the link key used by a BES/FS8-18 is reestablished. Please refer to the LKM/SSKM Encryption Admin Guide for the workaround.
Also, please ensure that two (2) SSKM’s are present in the deployment for workaround to be
performed.
For crypto tape operations, please ensure to use Emulex FC HBA firmware/drivers
2.82A4/7.2.50.007 or higher. Use of lower level firmware/drivers may result in hosts not being able to
access their tape LUNs through a crypto target container.

•

Adding of 3PAR Session/Enclosure LUNs to CTCs is now supported. Session/Enclosure LUNs (LUN
0xFE) used by 3PAR InServ arrays must be added to CryptoTarget (CTC) containers with LUN state set
to “cleartext”, encryption policy set to “cleartext”. BES/FS8-18 will not perform any explicit
enforcement of this requirement.

•

The Brocade Encryption switch and FS8-18 blade do not support QoS. When using encryption or
Frame Redirection, participating flows should not be included in QoS Zones.

•

FOS 7.1.0 or later will use SHA256 signatures for the TLS certificates used to connect to the ESKM 3.0
Server using ESKM 2.0 client. Upgrade from FOS v7.0.x to FOS 7.2 and downgrade from FOS 7.2 to
FOS v7.0.x would require regeneration and re-registration of CA and signed KAC certificates to restore
connectivity to the key vault. Please refer to the Encryption Admin Guide for more details on
ESKM/FOS compatibility matrix.

•

The RSA DPM Appliance SW v3.2 is supported. The procedure for setting up the DPM Appliance with
BES or a DCX/DCX-4S/DCX 8510 with FS8-18 blades is located in the Encryption Admin Guide.

•

Before upgrading from FOS v7.0.x to FOS7.2, it is required that the RKM server running SW v2.7.1.1
should be upgraded to DPM server running SW v3.2. Please refer to DPM/FOS compatibility matrix in
the Encryption Admin Guide for more details.

•

Support for registering a 2nd DPM Appliance on BES/FS8-18 is blocked. If the DPM Appliances are
clustered, then the virtual IP address hosted by a 3rd party IP load balancer for the DPM Cluster must
be registered on BES/FS8-18 in the primary slot for Key Vault IP.

•

With Windows and Veritas Volume Manager/Veritas Dynamic Multipathing, when LUN sizes less than
400MB are presented to BES for encryption, a host panic may occur and this configuration is not
supported in the FOS v6.3.1 or later release.

Fabric OS v7.2.1e Release Notes v1.0

Page 24 of 82

•

Hot Code Load from FOS v7.1.x to FOS v7.2 or later is supported. Cryptographic operations and I/O
will be disrupted but other layer 2 FC traffic will not be disrupted.

•

When disk and tape CTCs are hosted on the same encryption engine, re-keying cannot be done while
tape backup or restore operations are running. Re-keying operations must be scheduled at a time that
does not conflict with normal tape I/O operations. The LUNs should not be configured with auto rekey
option when single EE has disk and tape CTCs.

•

Gatekeeper LUNs used by SYMAPI on the host for configuring SRDF/TF using in-band management
must be added to their containers with LUN state as “cleartext”, encryption policy as “cleartext” and
without “-newLUN” option.

•

FOS 7.1.0 introduces support for “disk device decommissioning” to the following key vault types:
ESKM, TEKA, TKLM and KMIP. To use disk device decommissioning feature for these key vaults,
all the nodes in the encryption group must be running FOS v7.1.0 or later. Firmware downgrade will be
prevented from FOS v7.2 to a FOS v7.0.x if this feature is in use. Disk Device decommissioning for
DPM and LKM key vaults will continue to work as with previous firmware versions.

•

FOS7.2 supports KMIP key vault type for Thales e-Security Key Authority SW v4.0.0 KMIP servers.
Please refer to the KMIP Encryption Admin Guide for more details.

•

Replication feature from Thales e-Security Key Authority KMIP server is not supported with
BES/FS8-18.

•

In FOS 7.1.0 or later the encryption FPGA has been upgraded to include parity protection of lookup
memory (ROM) within the AES engine. This change enhances parity error detection capability of the
FPGA.

•

BES/FS8-18 will reject the SCSI commands WRITE SAME, ATS(Compare and Write/Vendor Specific
opcode 0xF1) and EXTENDED COPY, which are related to VAAI (vStorage APIs for Array Integration)
hardware acceleration in vSphere 4.1/5.x. This will result in non-VAAI methods of data transfer for the
underlying arrays, and may affect the performance of VM related operations.
VMware VMFS5 uses ATS commands with arrays that support ATS. BES/FS8-18 does not support this
command set. Use of a workaround procedure is required in order to configure encryption in a VMFS
5 environment. Please refer to Brocade Tech Note “Deployment Options for VMware VMFS-5 with
Brocade Encryption” for details.

•

XIV storage arrays that have been upgraded to firmware 11.2x or later required to support encryption
on thin provisioned LUNs will report all XIV data LUNs as TP=Yes.

FCIP (Brocade 7800 and FX8-24)
•

Any firmware activation will disrupt I/O traffic on FCIP links.

•

Latency measurements supported on FCIP Tunnels:
o

1GbE & 10GbE - 200ms round trip time and 1% loss.

•

After inserting a 4G SFP in GE ports of an FX8-24 blade or 7800 switch, sometimes “sfpshow”
output might display “Cannot read serial data!” . Removing and re-inserting the SFP should
resolve this issue. It is recommended that users perform sfpshow immediately after inserting
the SFP and ensure SFP is seated properly before connecting the cables.

•

When running FOS v7.2.0 or later, if the new FCIP Circuit Group feature is configured on any
FCIP Circuits, a downgrade operation to pre-FOS v7.2.0 will be blocked until the feature is
removed from the FCIP configuration(s).

Fabric OS v7.2.1e Release Notes v1.0

FCoE/DCB/CEE (FCOE10-24)
•

When upgrading a DCX/DCX-4S with one or more FCOE10-24 blades from FOS v6.x to FOS v7.0.0 or
later, the user should carefully review Chapter 5 of the FOS v7.0.0 Converged Enhanced Ethernet
Administrator’s Guide.

•

Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience
momentary traffic disruption during HA failover.

•

Hot plugging a CP with firmware level less than FOS v6.3.0 into a DCX or DCX-4S with an active
FCOE10-24 blade will result in the new standby CP not coming up.

•

When operating in Converged Mode, tagged traffic on the native VLAN of the switch interface is
processed normally. The host should be configured not to send VLAN tagged traffic on the switch’s
native VLAN.

•

When operating in Converged Mode, tagged frames coming with a VLAN tag equal to the configured
native VLAN are dropped.

•

The Converged Network Adapter (CNA) may lose connectivity to the FCOE10-24 if the CNA interface is
toggled repeatedly over time. This issue is related to the CNA and rebooting the CNA restores
connectivity.

•

The FCOE10-24 support only one CEE map on all interfaces connected to CNAs. Additionally, CEE map
is not recommended for use with non-FCoE traffic. QoS commands are recommended for interfaces
carrying non-FCoE traffic.

•

Before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, if the CEE map “default” value
already exists, the same “default” value is preserved after upgrading to FOS
v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later. However, if the CEE map “default” is not configured before
upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, then after upgrading to FOS
v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the following CEE map “default” will be created
automatically:
cee-map default
priority-group-table 1 weight 40 pfc
priority-group-table 2 weight 60
priority-table 2 2 2 1 2 2 2 2

•

When upgrading from FOS v6.3.x or v6.4.x to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the CEE
start up configuration dcf.conf file will be incompatible with the FCoE provisioning changes
implemented in v6.4.1_fcoe and later releases. Users can save the dcf.conf file as a backup and
apply it once the firmware upgrade is completed to get the DCX/DCX-4S to the same startup
configuration as in the older release.

•

It is recommended that Spanning Tree Protocol and its variants be disabled on CEE interfaces that are
connected to an FCoE device.

•

The Fabric Provided MAC Address (FPMA) and the Fibre Channel Identifier (FCID) assigned to a
VN_Port cannot be associated with any single front-end CEE port on which the FLOGI was received.

•

LLDP neighbor information may be released before the timer expires when DCBX is enabled on a CEE
interface. This occurs only when the CEE interface state changes from active to any other state.
When the DCBX is not enabled, the neighbor information is not released until the timer expires,
irrespective of the interface state.

•

The FCoE login group name should be unique in a fabric-wide FCoE login management configuration. If
there is a login group name conflict, the merge logic would rename the login group by including the
last three bytes of the switch WWN in the login group name. As long as the OUI of the switch WWNs
are identical this merge logic guarantees uniqueness in any modified login group name (switches with

Fabric OS v7.2.1e Release Notes v1.0

Page 26 of 82

the same OUI will have unique last 3 bytes in WWN). However, if the participating switches have
different OUIs but identical last three bytes in the switch WWNs, then the merge logic will fail to
guarantee uniqueness of login group names. This will result in one of the login groups being dropped
from the configuration. This means, no device can login to the login group that is dropped as a result
of this name conflict. Users must create a new login group with a non-conflicting name to allow device
logins.
•

Ethernet switch services must be explicitly enabled using the command “fosconfig –enable ethsw”
before powering on an FCOE10-24 blade. Failure to do so will cause the blade to be faulted (fault 9).
Users can enable ethsw after upgrading firmware without FC traffic interruption.

•

Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.4.1_fcoe1
to FOS v7.0 or later will be non-disruptive to FCoE traffic through FCOE10-24 blades and FC traffic.

•

Upgrading firmware on a DCX or DCX-4S with one or more FCOE10-24 blades from FOS v6.3.x, v6.4.x,
and v6.4.1_fcoe to FOS v7.0 or later will be disruptive to any traffic through the FCOE10-24 blades.

•

When rebooting a DCX or DCX-4S with an FCOE10-24 blade, Qlogic CNA and LSAN zoning, the switch
will become very unresponsive for a period of time. This is due to the CNA sending excessive MS
queries to the switch.

•

The FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the FCOE10-24, and
you delete a large number of v-ports with HCM, some of the v-ports may not appear to be deleted. To
correct this, disable and re-enable FCoE with the following CLI commands:
switch:admin>fcoe
fcoe –disable slot/port
switch:admin>fcoe
fcoe --enable
--enable slot/port

•

When a FCOE10-24 blade is powered off during configuration replay, the interface specific
configuration won’t get applied. Later when FCOE10-24 blade is powered on, all physical interfaces
will come up with default configurations. User can execute “copy startup-config running-config”
command to apply the new configuration after powering on the FCOE10-24 blade.

•

When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN.
User has to reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN.

FCR and Integrated Routing
•

With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs
unique.

•

VEX edge to VEX edge device sharing will not be supported.

Forward Error Correction (FEC)
•

Though FEC capability is generally supported on Condor3 (16G capable FC) ports when operating at
either 10G or 16G speed, it is not supported with all DWDM links. Hence FEC may need to be disabled
on Condor3 ports when using DWDM links with some vendors by using portCfgFec command. Failure
to disable FEC on these DWDM links may result in link failure during port bring up. Refer to the
Brocade Fabric OS 7.x Compatibility Matrix for supported DWDM equipment and restrictions on FEC
use.

FICON
•

For FICON qualified releases, please refer to the Appendix: Additional Considerations for FICON
Environments section for details and notes on deployment in FICON environments. (This appendix is
only included for releases that have completed FICON qualification).

FL_Port (Loop) Support
•

FL_Port is not supported on FC16-32, FC16-48, FC8-32E, FC8-48E, Brocade 6510, Brocade 6505
and Brocade 6520.

Fabric OS v7.2.1e Release Notes v1.0

Page 27 of 82

•

The FC8-48 and FC8-64 blade support attachment of loop devices.
•

Virtual Fabrics must be enabled on the chassis and loop devices may only be attached to ports on
a 48-port or 64-port blade assigned to a non-Default Logical Switch operating with the default 10bit addressing mode (they may not be in the default Logical Switch).

•

A maximum of 144 ports may be used for connectivity to loop devices in a single Logical Switch within
a chassis in 10-bit dynamic area mode on DCX-4S.

•

A maximum of 112 ports may be used for connectivity to loop devices in a single Logical Switch within
a chassis in 10-bit dynamic area mode on DCX.

•

Loop devices continue to be supported when attached to ports on the FC8-16, FC8-32 with no new
restrictions.

Flow Vision
•
•
•

Users must not specify well known FC addresses, domain controller addresses or CUP Port ID (in FMS
mode) for either the source or the destination device field while defining flows.
Flow Vision does not support port swap. Users must not create flows on ports that are already
swapped and users must not swap the ports on which the flows are currently defined.
After a HA reboot, a flow generator flow can be created if the source or the destination port is F-Port.
But traffic will not be initiated. Toggling the port will enforce the restriction again to simulated ports.

ICLs on DCX/DCX-4S
•

If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the 16link license will report enc_out errors. The errors are harmless, but will continue to increment. These
errors will not be reported if a DCX with a 16-link license is connected to a DCX-4S with only 8-link ICL
ports.

•

If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors.

Native Connectivity (M-EOS interoperability)
•

A switch running FOS v7.0 or later cannot form E-port connectivity with any M-EOS platform.

•

Platform running FOS v7.1 or later does not support EX port configuration in Interopmode 2 or
Interopmode 3.

•

Device sharing between a switch running FOS v7.1 or later and McDATA fabrics is allowed via
Integrated Routing platforms using FOS v7.0.x (or earlier) firmware.

Port Initialization
Users may observe that a port is in “Port Throttled” state when an F_Port is being initialized. This is mostly an
informational message that is shown in switchshow output indicating systematic initialization of F_Ports.
However, a port may remain in “Port Throttled” state for an extended period of time and may never come
online if it fails to negotiate speed successfully with the neighboring port. Users are advised to check the speed
setting of the neighboring switch port to determine the cause of the speed negotiation failure.

Page 28 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 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

Fabric OS v7.2.1e Release Notes v1.0

Page 29 of 82

•

FOS v7.3.0

FOS versions before the above listed ones do not support JRE 1.7.0 update 76. Users can use the
following workaround on a computer launching WebTools.
1. Go to C:\Program Files\Java\jre7\lib\security
2. Edit java.security file and change the value to 256 from 1024 for
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024

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.

•

There are limitations to zoning operations that can be performed from a FOS v6.x switch that is in the
same fabric as a FOS v7.0 or later switch if the FOS v6.x switch is not running the recommended
firmware version. Please see Fabric OS Interoperability section for details.

•

Beginning with the FOS v6.2.0 release, all WWNs containing upper-case characters are automatically
converted to lower-case when associated with a zone alias and stored as part of a saved configuration
on a switch. For example, a WWN entered as either “AA.BB.CC.DD.EE.FF.GG.HH” or
“aa.bb.cc.dd.ee.ff.gg.hh” when associated with a zone alias will be stored as “aa.bb.cc.dd.ee.ff.gg.hh”
on a switch operating with FOS v6.2.0 or later.
This behavioral change in saved zone alias WWN members will not impact most
environments. However, in a scenario where a switch with a zone alias WWN member with upper case
characters (saved on the switch with pre-FOS v6.2.0 code) is merged with a switch with the same alias
member WWN in lower case characters, the merge will fail, since the switches do not recognize these
zoning configurations as being the same.
For additional details and workaround solutions, please refer to the latest FOS Admin Guide updates
or contact Brocade Customer Support.

Miscellaneous
•

Users must also keep the RADIUS accounting port (Authentication Port+1) open in the firewall
to ensure proper working of the RADIUS authentication.

•

Using a Windows anonymous FTP server for supportsave collection:
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

Fabric OS v7.2.1e Release Notes v1.0

Page 30 of 82

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.

•

Support for the 16G 2km ICL QSFP optics has the following notes:
•

The maximum number of ICL ports with the 2km ICL QSFP can be supported in an 8510
backbone switch with the two kilometer distance is 10, which requires 16 credits
configured per Virtual Channel. More ports can be supported with less distance and fewer
credits. Full 16 ICL ports can be supported with 11 credits configured per Virtual Channel
for upto 1,375 meters.

•

Before the ICL ports with the 2km ICL QSFP come online, switchShow CLI command may
display the port states as in-sync or shifting in and out of port fault.

•

The sfpShow CLI command displays the 16G 2km ICL QSFP incorrectly as “Length Cu: 3
(units m)” instead of the correct value 0.

•

Firmware downgrade from FOS v7.2.1e to a prior version is blocked if ICL ports with 2km
ICL QSFP optics are present in the switch.

Technology Area: Security Vulnerability
Symptom: Bash shell security vulnerabilities (CVE-2014-6271, CVE-2014-7169, CVE-2014-7186, CVE-20147187). These vulnerabilities allows certain malformed function definition to bypass privilege
boundaries and execute unauthorized commands.
Condition: To exploit these vulnerabilities in FOS requires access to the CLI interface after user authentication
through console, Telnet, and SSH connections. An authenticated user account could exploit this bug
to gain privileges beyond the permission granted to this account, such as executing commands with
root privilege.
Workaround: Place switch and other data center critical infrastructure behind firewall to disallow access from
the Internet; Change all default account passwords; Delete guest accounts and temporary accounts
created for one-time usage needs; Utilize FOS password policy management to strengthen the
complexity, age, and history requirements of switch account passwords. Upgrading to a FOS
version including this fix prevents exposures to the four CVEs noted in the defect Symptom. In

Technology Area: Security Vulnerability
Symptom: Security vulnerability CVE-2014-3566 makes it easier for man-in-the-middle attackers to obtain
cleartext data via a padding-oracle attack,
Condition: Following are the conditions that customers of Brocade SAN products could be exposed to this
vulnerability:
•
An end user must use a web browser to access the FOS WebTools interface or use other
HTTP clients such as Brocade Network Adviser to manage the switch.
•
A web browser or other HTTP client must support SSL protocol 3.0.
•
An intruder has to interject between an HTTP client and a SAN switch.
•
An intruder has to spend time monitoring the request-response formats to gain knowledge of
the system operations. Total of 256 SSL 3.0 requests are required to decrypt one byte of HTTP
cookies.
Workaround: End users should configure their web browsers or Brocade Network Advisor to disable SSLv3
support when accessing Brocade SAN switch. In addition, place your Brocade SAN switch and
other data center critical infrastructure behind firewall to disallow access from the Internet to
minimize potential exposure to the attacks documented in this advisory.

Defect ID: DEFECT000513920
Technical Severity: High
Product: FOS
Technology: Security
Reported In Release: FOS7.1.0
Technology Area: Fabric Authentication
Symptom: CVE-2014-0224: OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not
properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle
attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications,
and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka
the "CCS Injection" vulnerability.
Condition: FOS switches that are not running LDAP or RADIUS with PEAP-MSCHAPv2 for authentication are
not running OpenSSL client mode and are not at risk. To be at risk:
• The FOS product must be running authentication using LDAP or RADIUS with PEAP-MSCHAPv2
protocols.
• The OpenSSL server must also be running with a version of OpenSSL that contains this
vulnerability (1.0.1 or 1.0.2-beta1)
Workaround: For users requiring LDAP or RADIUS with PEAP-MSCHAPv2 for authentication, upgrading the
OpenSSL server to a version of OpenSSL that does not contain this vulnerability will prevent
exposure.
