Overview Fabric OS (FOS) v7.1.0a is a patch release based on FOS v7.1.0. All hardware platforms and features supported in FOS v7.1.0 are also supported in FOS v7.1.0a. Warning – Applicable only if upgrading from FOS v7.1.0: Before upgrading the firmware to FOS v7.1.0a from FOS v7.1.0, you must run the supportSave command to save any existing error log information. Once the switch is upgraded to FOS v7.1.
Summary of New Software Features In addition to new hardware support, FOS v7.1 also includes support for several software features and enhancements: D_Port on optical ICLs of the DCX 8510 platforms New D_Port test options – users can specify number of frames, frame size, test duration, etc. Full D_Port support between Brocade 16G Adapter and 16G FC switch (requires Brocade adapter driver version 3.
New Feature Descriptions Diagnostic Port (D_Port) Enhancements FOS v7.1 implements the following enhancements to the D_Port functionality: Support for D_Port on optical ICL ports of DCX 8510 New D_Port test options D_Port between 16G Access Gateway and 16G FC Switch D_Port between 16G Switch and Brocade 16G FC Adapter Support for D_Port on Optical ICL ports of DCX 8510 FOS v7.1 implements D_Port functionality on the optical ICL ports of the DCX 8510 platforms.
FEC (Forward Error Correction) Support Enhancements FEC Support on Additional Links With FOS v7.1 FEC support is extended as follows: FEC support on links between 16G switch and 16G AG FEC support on links between 16G switch and Brocade 16G HBA (requires HBA driver 3.2 or later) FEC support on links between a pair 16G AGs (for cascaded Access Gateway Configurations) FEC support on links between 16G AG and Brocade 16G HBA (requires HBA driver 3.2 or later) Note: In FOS v7.0.
Sorting Security Policy Member List In a strict fabric wide consistency policy, if the security policy members are not in the same order, a newly joined switch will be segmented. To avoid segmentation of ports due to member list order mismatch, the security policy members are sorted by default. Newly added members to existing policies will also be sorted. FCIP Enhancements FOS v7.1 implements the following FCIP features and enhancements: Virtual Fabrics (VF) support on the Brocade 7800 FOS v7.
Name Server enhancements FDMI (Fabric Device Management Interface) enhancements Zoning Enhancements The zoning enhancements in FOS v7.1 are as follows: Ability to replace a zone member (WWN/D, I) by another member via the zoneobjectreplace command. Enhancement to the existing commands (zoneCreate, zoneAdd, zoneRemove) to take a collection of zone aliases as an input instead of a single alias member.
In FOS v7.1 the fcrfabricshow command has been enhanced to display the names of the edge fabrics attached to an FCR. iflShow Command In FOS v7.1 a new command “iflshow” is implemented to display the connection details between an edge switch and an FCR. This command is intended be executed on an edge switch, also provides details of VE-VEX connections. Note: Platforms running FOS v7.1 do not support EX_ Port configuration in Interopmode 2 or Interopmode 3. Access Gateway Enhancements FOS v7.
Update sfpShow data when a new SFP is plugged-in FOS v7.1 has been enhanced to update the SFP serial data information when a new SFP is inserted even in a disabled port, and to show the "valid" data (Temperature, Current, Voltage and Tx/Rx power, etc.) once the port is enabled and SFP data has been polled for that port. Time stamp for SFP polling In FOS v7.1 a new field has been added in the command “sfpshow port# [-f]” to display the last poll time stamp for a port.
Frame Viewer (Class 3 Discard Log) Enhancements In FOS v7.1 Frame Viewer has been enhanced to display class 3 discard log messages associated with the backend ports (internal ports) of a chassis. Backend Link Monitoring Enhancements FOS v7.1 introduces three different options/policies to fault the core blade/edge blade when the link reset threshold of a Back End (BE) port is exceeded. Please see the bottleneckmon command description for additional details. LR_IN and LR_OUT in fabriclog FOS v7.
Miscellaneous Enhancements Credit Recovery Support on F_Ports to Brocade HBA FOS v7.1 implements credit recovery mechanisms on F_Ports connecting to Brocade 8G or 16G HBAs. Credit Recovery alert to the User Level RASlog FOS v7.1 adds a user level RASlog Cxx_1023 to alert about buffer credit recovery performed on 16G FC platforms. This RASlog is generated whenever a single credit loss was detected and automatically recovered. This RASlog can be viewed by using the errDump command.
SuperPing Enhancements In FOS v7.1, SuperPing for FCIP supports the following features: Traverse all possible FCIP links based on FCIP routing. Display all possible VE and GE link in path. Fabric OS v7.1.0a Release Notes v1.

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 v7.0.x can be non-disruptively upgraded to FOS v7.1.0a. This upgrade is non-disruptive to both FC and FCoE traffic (when using FCOE10-24 blades). FR4-18i and FC10-6 blades are not supported on DCX/DCX-4S with FOS v7.1.
Migrating from FOS v6.4.x DCX/DCX-4S units running any FOS v6.4.x firmware must be upgraded to FOS v7.0.x before they can be nondisruptively upgraded to FOS v7.1. Any 8G platforms (other than DCX/DCX-4S) that are currently operating at lower than FOS v6.4.1a must be upgraded to FOS v6.4.1a or later, they then must be upgraded to FOS v7.0.x, before non-disruptively upgrading to FOS v7.1.0. Upgrading these platforms from any FOS V6.4.x release lower than FOS v6.4.1a to FOS v7.0.
Important Notes This section contains information that you should consider before you use this Fabric OS release. Brocade Network Advisor Compatibility Brocade® Network Advisor provides the industry’s first unified network management solution for data, storage, and converged networks.

o Go to Documentation > Tech Notes. o 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.
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.
Hot Code Load from FOS v6.4.1a to FOS v7.0 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.
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.
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 Brocade 8000/FCOE10-24 if the CNA interface is toggled repeatedly over time.
The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade 8000 to FOS v7.1 or downgrading from v7.1 is disruptive to the IO through the switch. 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.
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.
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.
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.
