Overview Fabric OS (FOS) v7.2.1 is a maintenance release based on FOS v7.2.0. All hardware platforms and features supported in FOS v7.2.0 are also supported in FOS v7.2.1. This release also contains fixes for many defects including those from the FOS v7.2.0a and b patch releases. In addition to the fixes noted above and listed in the defect tables at the end of this document, FOS v7.2.1 also includes support for additional hardware platforms and enhanced capabilities.
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 license key upgrade. (Applies to select models of switches).
Adaptive Networking with QoS—Adaptive Networking provides a rich framework of capability allowing a user to 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.
10GbE FCIP/10G Fibre Channel – This license enables the two 10GbE ports on the FX8-24 and/or the 10G FC capability on FC16-xx blade ports supported on DCX 8510 platforms. On the Brocade 6510, Brocade 6520 this license enables 10G FC ports.
Temporary License Support The following licenses are available in FOS v7.
Supported Switches FOS v7.2.1 supports the following existing platforms: 300, 5100, 5300, 7800, VA-40FC, Brocade Encryption Switch, DCX, DCX-4S 6505, 6510, 6520, DCX 8510-8, DCX 8510-4 FC16-32, FC16-48, FC8-32E, FC8-48E, FX8-24, FS8-18 on DCX 8510-8/DCX 8510-4 FC8-16, FC8-32, FC8-48, FC8-64, FX8-24, FS8-18, FCOE10-24 on DCX/DCX-4S 5410, 5424, 5430, 5450, 5480, 5470, 5460, NC-5480 Support merged to FOS v7.2.
Switch operating system version Error numbers and messages received supportSave command output and associated files o For dual CP platforms running FOS v6.
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 v7.2.1. 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.
Important Notes This section contains information that you should consider before you use this Fabric OS release. Brocade Network Advisor Compatibility Brocade Network Advisor greatly simplifies the steps involved in daily operations while improving the performance and reliability of the overall SAN and IP networking environment. Brocade Network Advisor unifies, under a single platform, network management for SAN, LAN and converged networks.
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.
Multi-Protocol Router Interoperability Brocade 7500 and FR4-18i blade V6.2.2 and higher 4 6 8 McDATA SANRouters 1620 and 2640 Not Supported NOS (VDX Platform) Interoperability Brocade VDX6710, VDX6720, VDX6730 NOS v2.1.1 or later7 Brocade VDX8770 NOS 3.0 or later Table Notes: 1 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.
SNMP Support Starting with FOS v7.2.0, the Fabric OS MIB Reference document is not updated. You can obtain the latest MIBs from the downloads area of MyBrocade site after logging in. For information about SNMP support in Fabric Operating System (FOS) and how to use MIBs, see the Fabric OS Administrator’s Guide. Obtaining the MIBs You can download the MIB files required for this release from the downloads area of the MyBrocade site.

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.
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.
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. 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.
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.
are identical this merge logic guarantees uniqueness in any modified login group name (switches with 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.
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. 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).
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. Example Output: 74 9 10 Throttled) 36ed40 id N8 In_Sync FC Disabled (Port Port Mirroring Port Mirroring is not supported on the Brocade 7800.
“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.
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.
