Overview Fabric OS (FOS) v7.2.1e is a patch release based on FOS v7.2.1d. All hardware platforms and features supported in FOS v7.2.1 are also supported in FOS v7.2.1e. This release contains fixes for many defects. This release also merge in the support for long distance 16G optical cable QSFP that extends the ICL connectivity up to two kilometers (km). Resolution of Important Defects This release contains the following important fixes.
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).
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.
10GbE FCIP/10 FCIP/10G 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, FC8-64, 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, M5424, 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 v7.2.1e. 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.
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.
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.

• 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.
• 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.
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.
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.
• 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.
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.
• 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.
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.
