Overview Fabric OS (FOS) v7.2.1a is a patch release based on FOS v7.2.1. All hardware platforms and features supported in FOS v7.2.1 are also supported in FOS v7.2.1a. This release also contains fixes for many defects including those from the FOS v7.2.0d patch releases. Due to the impact of defect 491192 and 494570, Brocade recommends all customers planning or using FOS v7.2.1 to upgrade to FOS v7.2.1a. Note: If customers are already running FOS v7.2.1 on their switches, and the “Custom.
Brocade Extended Fabrics—Provides greater than 10km of switched fabric connectivity at full bandwidth over 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— Provides the ability to aggregate multiple physical links into one logical link for enhanced network performance and fault tolerance.
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.

This license is available on the DCX/DCX-4S/DCX 8510-8/DCX 8510-4 on an individual slot basis.
Temporary License Support The following licenses are available in FOS 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.x or FOS v7.2.0x can be non-disruptively upgraded to FOS v7.2.1a. 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.
on version 12.1.5 or later. With JRE 1.7.0 update 51, users could see some browser warning messages that can be ignored. 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.

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.
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.
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.
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.
