Overview Fabric OS (FOS) v7.2.0a is a patch release based on FOS v7.2.0. All hardware platforms and features supported in FOS v7.2.0 are also supported in FOS v7.2.0a. New Hardware Support FOS v7.2 does not introduce support for any new hardware platform, while it adds support for the existing embedded switches 5431, 6547 and M6505 on a major FOS release. Summary of New Software Features FOS v7.
New Feature Descriptions MAPS (Monitoring and Alerting Policy Suite) FOS v7.2 implements a new easy to use policy based monitoring and alerting suite that proactively monitors the health and performance of the SAN infrastructure to ensure application uptime and availability. Brocade MAPS helps users to uncover potential problems in the SAN fabric quickly, before they cause application performance impacts or costly failures.
minute, send an e-mail notification when the error rate is at five per minute, and fence a port when the error rate exceeds ten per minute. Ability to monitor both sudden failures and gradual degradations MAPS provides the ability to not only detect abnormal conditions but also gradually deteriorating conditions in the switch. For example, if a CRC error counter at a switch port increments suddenly at the rate of five per minute, MAPS can detect and alert the end users about that condition.
Bottleneck Detection integration with MAPS dashboard Bottleneck Detection information is integrated with MAPS dashboard. The “Summary” section of the dashboard shows bottleneck events detected by the Bottleneck Monitor. The “History” section of the dashboard shows entries for bottlenecked ports, including transient bottlenecks that are not detected by the Bottleneck Monitor. This enables users to get at an instant view of the bottlenecked ports in the switch and enables rapid problem resolution.
Flow Generator: Flow generator is a test traffic generator for pre-testing the SAN infrastructure (including internal connections) for robustness before deploying the applications. Allows users to configure a16G FC capable port as a simulated device that can transmit frames at full 16G line rate.
ClearLink Diagnostics: D_Port Enhancements FOS v7.2 adds the following D_Port enhancements: Enhancement to D_Port test results Starting with FOS v7.2 complete results of the D_Port tests will be available on the responder switch as well. Prior to FOS v7.2, D_Port test results on the D_Port responder switch did not include optical and remote loopback test results. Complete results were only available on the D_Port initiator switch. D_Port support between Brocade 16G HBA and Brocade 16G Access Gateway.
FOS v7.2 allows buffer credit assignment even for “normal distance” (regular) E_ports The portCfgEportCredits CLI introduced in FOS v7.2 allows users to perform fine grained performance tuning on normal E_ports by allowing users to specify buffer credits. In FOS v7.2, the portaddess CLI has been enhanced to display an address as user bound when a user has explicitly bound an address to a port. FOS v7.
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 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: 5431, 6547, M6505 Access Gateway mode is also supported by Fabric OS v7.

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 can be non-disruptively upgraded to FOS v7.2.0a. This upgrade is nondisruptive 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.

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).
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.
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”.
