Fabric OS v7.0.2 Release Notes v1.0 Page 4 of 99

Overview

Fabric OS (FOS) v7.0.2 is a maintenance release based on FOS v7.0.1x. All hardware platforms and features supported in FOS v7.0.1x are also supported in FOS v7.0.2.

Resolution of Important Defects

• 404780 High count of CRC w/Good EOF errors across multiple card types

• 403996 Enhancement needed to link credit loss recovery on 8G platforms

FOS v7.0.2 Features

FOS v7.0.2 is a maintenance release that contains fixes for defects including those from FOS v7.0.1a and FOS v7.0.1b patch releases. In addition this release includes the following features and enhancements:

• D_Port Enhancements

o D_Port link saturation capability – ability to drive test traffic to saturate link utilization close to

line rate as part of D_Port test

• Ability to assign individual ports of an optical ICL to logical switches o Prior to FOS v7.0.2, in Virtual Fabrics enabled environment, an entire ICL port (which includes

four individual ports as part of a single QSFP) has to be associated with a single logical switch. Starting with FOS v7.0.2, the individual ports within an optical ICL can be assigned to different logical switches. This feature is applicable to the DCX8510 platforms.

Note:

Note: Please note that if any individual port of a QSFP is part of the Base Switch, the

Note:Note: remaining ports of that QSFP cannot be assigned to any other logical switch.

• Bottleneck detection enhancements - Decoupling of latency and congestion alerts

In FOS v7.x releases prior to FOS v7.0.2, when users enabled bottleneck alerts, it would enable alerting for both congestion and latency bottleneck conditions. Starting with FOS v7.0.2 users can choose to enable alerts only for latency bottleneck while not enabling alerts for congestion bottleneck or vice versa. Users still have the option to enable alerts for both congestion and latency bottleneck conditions.

Fabric OS v7.0.2 Release Notes v1.0 Page 5 of 99

FOS v7.0.1 Feature Descriptions

New Hardware Support

• Brocade 6505 entry level 16G FC switch

• FC8-32E and FC8-48E Condor3 based 8G blades for DCX 8510-8 and DCX 8510-4

Enhanced Optical ICL Topology Support for DCX 8510

FOS v7.0.1 supports the following enhanced topologies using optical ICLs:

• Support for up to nine DCX 8510 chassis in full mesh configuration using optical ICLs

• Support for ICL connectivity with up to ten DCX 8510 chassis in core-edge topology

This increased support delivers massive scalability, significantly reduces cabling complexity, and also makes more ports available for device connectivity.

FOS v7.0.1 also adds support for Enterprise ICL license on DCX 8510 platforms. Description of this license can be found in the “Optionally Licensed Software” section of this document.

Support for Dynamic Fabric Provisioning: Fabric Assigned World Wide Name

In order to simplify and accelerate server deployment and improve operational efficiency, FOS v7.0.1 provides Fabric Assigned WWN or FA-PWWN capability. This feature allows users to create a virtual WWN for a server instead of using the server’s physical port WWN (PWWN) to create zoning and LUN mapping/masking. When a FA-PWWN capable server is attached to the SAN, this feature allows the fabric to assign this virtual WWN to that server. This feature requires servers to be using Brocade HBAs/Adapters. Please consult Brocade HBA/Adapter driver documentation and Release Notes to confirm minimum requirements for this feature. For Brocade Network Advisor support, please consult Brocade Network Advisor documentation and Release Notes.

VCS/VDX6730 to FC SAN Connectivity

This feature enables connectivity between hosts (using FCoE) connected to VCS/VDX platforms and FC storage connected to FC SAN via FCR. An E-port on a VDX6730 platform running NOS v2.1.1 is connected to an EX_port on an FCR running FOS v7.0.1 to enable this functionality.

Note:

Note:Note:

• Integrated Routing license is not required to share devices between VDX/VCS Ethernet fabric and FC

SAN fabric.

• It is recommended to use 5300, DCX/DCX-4S, DCX 8510-8, DCX 8510-4 for FCR functionality for

higher scalability.

• A new FCR EX_port mode 5 is used to connect VCS/VDX6730 to FCR

FCIP Enhancements

FOS v7.0.1 enables ESCON and Bus/Tag printer emulation support on FCIP platforms.

This feature provides near native performance for FICON Extended paths to remote ESCON or Bus and Tag printers. Enabling FICON Printer emulation requires the Advanced FICON Acceleration license. This feature is supported on 7800 and FX8-24.

D-port (Diagnostic Port) Support between Brocade 16G Fabric Adapter and Brocade 16G FC switch

D-port functionality is supported between a Brocade 16G Fabric Adapter with adapter firmware version 3.1 or later, and a Brocade 16G FC switch running FOS v7.0.1 or later. This feature requires usage of 16G SFP+ at

Fabric OS v7.0.2 Release Notes v1.0 Page 6 of 99

both the adapter and the switch. For additional information please consult the Brocade Adapter Release Notes for firmware version 3.1 or later, and the Brocade Adapter Administrator’s Guide.

FOS Upgrade and Downgrade Special Considerations

The DCX/DCX-4S units running any FOS v6.4.x can be non-disruptively upgraded to FOS v7.0.2. This upgrade is non-disruptive to FC traffic only. When loading FOS v7.0.2 to a DCX chassis with FCOE10-24 blades with Brocade Network Advisor v11.1.1/11.1.1a, there is no warning flagging FCoE traffic disruption.

The DCX/DCX-4S units running FOS v6.4.1_fcoe1 can be non-disruptively upgraded to FOS v7.0.2. This upgrade is non-disruptive to both FCoE traffic through FCOE10-24 blades and FC traffic.

Non-disruptive upgrade to FOS v7.0.2 on 8G switches is allowed from FOS

Disruptive

Disruptive upgrades to Fabric OS 7.0.2 are allowed and supported from FOS 6.3 (up to a two-level migration)

DisruptiveDisruptive using the optional “-s” parameter with the firmwaredownload command.

If there are multiple node EGs (encryption groups) in a fabric, please complete firmwaredownload on one node at a time before downloading on another node.

The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade 8000 to FOS v7.0 .1 will be disruptive to the I/O through the switch.

FC FastWrite , EX_Ports, and TCP byte streaming on FR4-18i must be disabled prior to upgrading to FOS v7.0.2. Failure to do so will cause the upgrade to be blocked. Upgrading a switch currently operating in interopmode 2 or 3 to FOS v7.0.2 is disruptive. The interopmode must be changed to 0 prior to upgrading to FOS v7.0.2, as interopmodes 2 and 3 are not supported on FOS v7.0.2. Changing the interopmode is an offline operation.

Notes:

1. When 2+2 power supply combination is used, the users are advised to configure the Fabric Watch setting for switch marginal state to be two power supplies. Users can use the CLI switchstatuspolicyset to configure this value if the current value is set to zero. In FOS v7.0.x, the default setting for the marginal state due to missing power supplies is incorrectly set to zero (Defect 000349586), which will prevent Fabric Watch from generating notifications when the switch enters the marginal state due to missing power supplies

Other Important Notes and Recommendations

Adaptive Networking/Flow-Based QoS Prioritization

• Any 8G or 4G FC platform running FOS v6.2.2e or lower version of firmware cannot form an E-port with a 16G FC platform when Adaptive Networking QoS is enabled at both ends of the ISL. Users must disable QoS at either end of the ISL in order to successfully form an E-port under this condition.

Users can disable QoS via portcfgQos --disable command. Please consult Fabric OS Command Reference manual for details related to portcfgQoS command.

• When using QoS in a fabric with 4G ports or switches, FOS v6.2.2 or later must be installed on all products in order to pass QoS info. E_Ports from the DCX to other switches must come up AFTER

6.2.2 is running on those switches.

Access Gateway

• AG cascading is not supported on Brocade 6510, Brocade 6505 in FOS v7.0.1 or later.

• Users who want to utilize Access Gateway’s Device-based mapping feature in the ESX environments

are encouraged to refer to the SAN TechNote GA-TN-276-00 for best implementation practices. Please follow these instructions to access this technote:

o Log in to http://my.brocade.com

o Go to Documentation > Tech Notes.

Fabric OS v7.0.2 Release Notes v1.0 Page 23 of 99

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

• D-port tests must be run with FEC disabled. Sometimes, a D-Port test may get stuck in “IN PROGRESS” state, when FEC is enabled for a port. The D-Port stuck in “IN PROGRESS” state can be recovered by toggling the port (port disable/enable).

• FOS v7.0.0a and later support the execution of D-Port tests concurrently on up to eight ports on the switch.

• D-Port tests may only be executed on ports configured for “portcfglongdistance port# L0” or normal port distance mode. Executing D-Port tests on long distance ports may cause tests to fail due to time out exceeded.

•

Support of D-Port is extended to R_RDY flow control mode. The R_RDY mode is useful for active DWDM links that do not work in VC_RDY or EXT_VC_RDY flow control modes.

• A new sub-option “-dwdm” is added to “portcfgdport --enable” CLI to configure D-Port over active DWDM links. The “-dwdm” option will not execute the optical loopback test while performing D-Port tests as the active

active DWDM links do not provide necessary support to run optical loopback tests.

Encryption Behavior for the Brocade Encryption Switch (BES) and FS8-18

• SafeNet’s KeySecure hosting NetApp’s LKM (SSKM) is supported for data encryption operations with FOS v7.0.1 or later.

• Use of SSKM with the Brocade encryption solution is only supported for SSKM operating in PVM mode. Please see SSKM documentation for operating in PVM mode for details. Operation in HVM mode is not supported.

• It is recommended to use Tight VNC connection to access the management console for SSKM and LKM key vaults instead of remote desktop. If remote desktop is used, customer may encounter the following errors related to smart card reader:

 Error communicating with smart card reader.  Card reader already in use by default key.  Unable to complete TEP/TAP process as window for selecting card and entering

password does not appear.

• Please refer to SafeNet Keysecure install documentation for setting up and initially configuring the SSKM key vaults. There are some changes between setting up the SSKMs and the LKMs. Please refer SafeNet or NetApp documentation for any LKM to SSKM migration procedures. This migration is not tested/supported with FOS v7.0.1 or later.

• The following is tested and supported with FOS v7.0.1 or later.

 Platform Serial Number: 27CJNQ1  Platform FW Version: SSKM-1.0-03  Platform Firmware Build ID: 0.5_secure  DB version: 166  SEP FW ID: SEPLuna TDB  SEP HW ID: Luna K6 TBD  SEP SW ID: 6.2.0 TBD  System Card FW ID: 200.5  Management console version: 1.0 build 18.

• For crypto tape operations, please ensure to use Emulex FC HBA firmware/drivers

2.82A4/7.2.50.007 or higher. Use of lower level firmware/drivers may result in hosts not being able to access their tape LUNs through a crypto target container.

Fabric OS v7.0.2 Release Notes v1.0 Page 24 of 99

• If the migration to FOS v7.0 or later does not occur from 6.4.1a, 6.4.1b, or 6.4.2, the following will result

• BES will reboot if auto reboot is enabled otherwise it needs to be rebooted manually for recovery2010/11/08-04:54:35:485488, [FSS-1009], 4424/886, CHASSIS, ERROR, MACE, FSS Error: fcsw0-vs: MISMATCH: component., svc.c, line: 2462, comp:FSSK_TH, ltime:2010/11/08-04:54:35:485484

• 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.

• The “cryptocfg –manual_rekey –all” command should not be used in environments with multiple encryption engines (FS8-18 blades) installed in a DCX/DCX-4S/DCX 8510 chassis with more than one encryption engine has access to the same LUN. In such situations, use the “cryptocfg –manual_rekey <CTC> <LUN Num> <Initiator PWWN>” command to manually rekey these LUNs.

• When host clusters are deployed in an Encryption environment, please note the following recommendations:

• If two EEs (encryption engines) are part of a HAC (High Availability Cluster), configure the host/target pair such that they form a multipath from both EEs. Avoid connecting both the host/target pairs to the same EE. This connectivity does not give full redundancy in the case of EE failure resulting in HAC failover.

• Since quorum disk plays a vital role in keeping the cluster in sync, please configure the quorum disk to be outside of the encryption environment.

• The “–key_lifespan” option has no effect for “cryptocfg –add –LUN”, and only has an effect for “cryptocfg --create –tapepool” for tape pools declared “-encryption_format native”. For all other encryption cases, a new key is generated each time a medium is rewound and block zero is written or overwritten. For the same reason, the “Key Life” field in the output of “cryptocfg --show -container -all –stat” should always be ignored, and the “Key life” field in “cryptocfg --show –tapepool –cfg” is only significant for native-encrypted pools.

• The Quorum Authentication feature requires a compatible DCFM or Brocade Network Advisor release (DCFM 10.3 or later for pre-FOS v7.0 and Network Advisor 11.1 or later for FOS v7.0 or later) that supports this feature. Note, all nodes in the EG must be running FOS v6.3.0 or later for quorum authentication to be properly supported.

• The System Card feature requires a compatible DCFM or Brocade Network Advisor release (DCFM

10.3 or later for pre-FOS v7.0 and Network Advisor 11.1 or later for FOS v7.0 or later) that supports this feature. Note, all nodes in the EG must be running FOS v6.3.0 or later for system verification to be properly supported.

• The Brocade Encryption switch and FS8-18 blade do not support QoS. When using encryption or Frame Redirection, participating flows should not be included in QoS Zones.

• HP SKM & ESKM are supported with Multiple Nodes and Dual SKM/ESKM Key Vaults. Two-way certificate exchange is supported. Please refer to the Encryption Admin Guide for configuration information. If using dual SKMs or ESKMs on BES/FS8-18 Encryption Group, then these SKM / ESKM Appliances must be clustered. Failure to cluster will result in key creation failure. Otherwise, register only one SKM / ESKM on the BES/FS8-18 Encryption Group.

• The RSA RKM Appliance A1.6, SW v2.7.1.1 is supported. The procedure for setting up the RKM Appliance with BES or a DCX/DCX-4S/DCX 8510 with FS8-18 blades is located in the Encryption Admin Guide.

• Support for registering a 2nd RKM Appliance on BES/FS8-18 is blocked. If the RKM Appliances are clustered, then the virtual IP address hosted by a 3rd party IP load balancer for the RKM Cluster must be registered on BES/FS8-18 in the primary slot for Key Vault IP.

Fabric OS v7.0.2 Release Notes v1.0 Page 25 of 99

• 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 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. The LUNs should not be configured with auto rekey option when single EE has disk and tape CTCs.

• Gatekeeper LUNs used by SYMAPI on the host for configuring SRDF/TF using in-band management must be added to their containers with LUN state as “cleartext”, encryption policy as “cleartext” and without “-newLUN” option.

• For new features added to encryption in FOS v6.4.0, such as, disk device decommissioning, combined disk-tape encryption support on the same encryption engine, and redundant key ID metadata option for replication environments, all the nodes in the encryption group must be running FOS v6.4.0 or higher versions of FOS. Firmware downgrade will be prevented from FOS v6.4.0 to a lower version if one or more of these features are in use.

• Special Notes for HP Data Protector backup/restore application

• Tape Pool encryption policy specification:

• On Windows Systems, HP Data Protector can be used with tape pool encryption

specification only if the following pool label options are used:

 Pick from Barcode

 User Supplied – Only 9 characters or less

For other options, behavior defaults to Tape LUN encryption policy.

• On HP-UX systems, HP Data Protector cannot be used with tape pool encryption specification for any of the pool options. The behavior defaults to Tape LUN Encryption Policy.

• Tape LUN encryption policy specification:

• No restrictions, tape LUN encryption policy specification can be used with HP Data

Protector on HP-UX and Windows systems.

• BES/FS8-18 will reject the SCSI commands WRITE SAME and EXTENDED COPY, which are related to VAAI (vStorage APIs for Array Integration) hardware acceleration in vSphere 4.1. This will result in nonVAAI methods of data transfer for the underlying arrays, and may affect the performance of VM related operations.

FCIP (FR4-18i, 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. It is recommended that users perform sfpshow immediately after inserting the SFP and ensure SFP is seated properly before connecting the cables.

• When running FOS v7.0.0 or later, if any of the following features are enabled in the FCIP configuration, a downgrade operation to pre-FOS v7.0.0 will be blocked until the features are removed from the FCIP configuration:

Fabric OS v7.0.2 Release Notes v1.0 Page 26 of 99

o InBand Management

o Multigigabit Circuit

o Shared GE among Logical Switches

o Auto-mode compression option

o VE as XISL

o 10GigE lossless failover

o Modified QoS percentages

o 10GigE ARL

o IP Configuration where multiple GigEs have same subnet values

o For a tunnel configuration on 1GE ports that has more than 4 circuits

o Teradata emulation enabled

o Circuits configured explicitly to be listeners or an initiators

FCoE/DCB/CEE (Brocade 8000 and FCOE10-24)

• When upgrading a Brocade 8000 or 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.

• FOS v7.0 or later supports a new optimized model for provisioning FCoE with fewer configuration steps to enable FCoE on DCB ports. These changes do not allow the Brocade 8000 to retain FCoE configuration information following an upgrade to FOS v7.0 or later. After the upgrade to FOS v7.0 or later, all FCoE edge ports will need to be provisioned with the new model before any FIP FLOGIs will take place

• Although including Brocade 8000 in the path of TI (Traffic Isolation) and ETI (Enhanced Traffic Isolation) Zones is not prohibited, it is not supported. Configuring Brocade 8000 in the TI/ETI Zone path is not recommended and will result in undefined behavior.

• Ethernet L2 traffic with xSTP Hello timer set to less than or equal to 3 seconds may experience momentary traffic disruption during HA failover.

• The Brocade 8000 balances the FCoE bandwidth across all six port groups (each port group contains four ports). To get optimum performance for FCoE traffic it is recommended that the user distribute server CNA connections across these six port groups.

• Hot plugging a CP with firmware level less than FOS v6.3.0 into a DCX or DCX-4S with an active FCOE10-24 blade will result in the new standby CP not coming up.

• 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. This issue is related to the CNA and rebooting the CNA restores connectivity.

• The Brocade 8000 and FCOE10-24 support only one CEE map on all interfaces connected to CNAs. Additionally, CEE map is not recommended for use with non-FCoE traffic. QoS commands are recommended for interfaces carrying non-FCoE traffic.

Fabric OS v7.0.2 Release Notes v1.0 Page 27 of 99

• Before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, if the CEE map “default” value already exists, the same “default” value is preserved after upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later. However, if the CEE map “default” is not configured before upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, then after upgrading to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the following CEE map “default” will be created automatically:

cee-map default

priority-group-table 1 weight 40 pfc

priority-group-table 2 weight 60

priority-table 2 2 2 1 2 2 2 2

• When upgrading from FOS v6.3.x or v6.4.x to FOS v6.4.1_fcoe/v6.4.1_fcoe1/v7.0.0 or later, the CEE start up configuration dcf.conf file will be incompatible with the FCoE provisioning changes implemented in v6.4.1_fcoe and later releases. Users can save the dcf.conf file as a backup and apply it once the firmware upgrade is completed to get the DCX/DCX-4S to the same startup configuration as in the older release.

• It is recommended that Spanning Tree Protocol and its variants be disabled on CEE interfaces that are connected to an FCoE device.

• The Fabric Provided MAC Address (FPMA) and the Fibre Channel Identifier (FCID) assigned to a VN_Port cannot be associated with any single front-end CEE port on which the FLOGI was received.

• LLDP neighbor information may be released before the timer expires when DCBX is enabled on a CEE interface. This occurs only when the CEE interface state changes from active to any other state. When the DCBX is not enabled, the neighbor information is not released until the timer expires, irrespective of the interface state.

• The FCoE login group name should be unique in a fabric-wide FCoE login management configuration. If there is a login group name conflict, the merge logic would rename the login group by including the last three bytes of the switch WWN in the login group name. As long as the OUI of the switch WWNs 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. 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.

• Ethernet switch services must be explicitly enabled using the command “fosconfig –enable ethsw” before powering on an FCOE10-24 blade. Failure to do so will cause the blade to be faulted (fault 9). Users can enable ethsw after upgrading firmware without FC traffic interruption.

• The Brocade 8000 does not support non-disruptive hot code loads (HCL). Upgrading the Brocade 8000 to FOS v7.0.x or downgrading from v7.0.x 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 v7.0 or later will be disruptive to any traffic through the FCOE10-24 blades.

• Connecting Brocade 8000 to an FCR-capable switch with fcrbcast config enabled will cause a storm of broadcast traffic resulting in termination of iswitchd.

• When rebooting a DCX or DCX-4S with an FCOE10-24 blade, Qlogic CNA and LSAN zoning, the switch will become very unresponsive for a period of time. This is due to the CNA sending excessive MS queries to the switch.

Fabric OS v7.0.2 Release Notes v1.0 Page 28 of 99

• The Brocade 8000 and FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the Brocade 8000 or FCOE10-24, and you delete a large number of v-ports with HCM, some of the v-ports may not appear to be deleted. To correct this, disable and re-enable FCoE with the following CLI commands:

switch:admin>fcoe

• When a FCOE10-24 blade is powered off during configuration replay, the interface specific configuration won’t get applied. Later when FCOE10-24 blade is powered on, all physical interfaces will come up with default configurations. User can execute “copy startup-config running-config” command to apply the new configuration after powering on the FCOE10-24 blade.

• When IGMP Snooping is disabled on a VLAN, all configured IGMP groups are removed from that VLAN. User has to reconfigure the IGMP groups after enabling the IGMP snooping on that VLAN.

FCR and Integrated Routing

• With routing and dual backbone fabrics, the backbone fabric ID must be changed to keep the IDs unique.

• When using FC Routing in a backbone to edge configuration with an Mi10K in the edge fabric, users may experience slow throughput for hosts attached to the Mi10K. Users may encounter this following a bounced IFL connection between the backbone and edge fabric. This slowdown can be resolved by disabling/enabling the Mi10K ports for the hosts that are impacted.

• Mi10K Directors operating with firmware prior to M-EOSn v9.9.5 may experience repeated system faults when attached as an FCR edge switch to a Brocade 7800 EX Port. To avoid this, ensure that the Mi10K is operating with M-EOSn v9.9.5 or later when in an edge fabric that will be attached to a Brocade 7800 FCR Backbone.

• VEX edge to VEX edge device sharing will not be supported.

• To allow Hot Code Load on Brocade 5100 when using Integrated Routing, the edge switch connected

to the 5100 must be running Fabric OS v6.1 or later code.

Forward Error Correction (FEC)

• Though FEC capability is generally supported on Condor3 (16G capable FC) ports when operating at either 10G or 16G speed, it is not supported when using active DWDM links. Hence FEC must be disabled on Condor3 ports when using active DWDM links by using portCfgFec command. Failure to disable FEC on active DWDM links may result in link failure during port bring up.

FICON

• For FICON qualified releases, please refer to the Appendix: Additional Considerations for FICON Environments section for details and notes on deployment in FICON environments. (This appendix is

only included for releases that have completed FICON qualification).

FL_Port (Loop) Support

• FL_Port is not supported on FC16-32, FC16-48, FC8-32E, FC8-48E, Brocade 6510, and Brocade

6505.

• 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.

Fabric OS v7.0.2 Release Notes v1.0 Page 29 of 99

• A maximum of 112 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.

• Loop devices continue to be supported when attached to ports on the FC8-16, FC8-32 with no new restrictions

ICLs on DCX/DCX-4S

• If a DCX with an 8-link ICL license is connected to a DCX with a 16-link license, the DCX with the 16link license will report enc_out errors. The errors are harmless, but will continue to increment. These errors will not be reported if a DCX with a 16-link license is connected to a DCX-4S with only 8-link ICL ports.

• If ICL ports are disabled on only one side of an ICL link, the enabled side may see enc_out errors.

Native Connectivity (M-EOS interoperability)

• A switch running FOS v7.0 or later cannot form E-port connectivity with any M-EOS platform. A switch running FOS v7.0 or later can only operate in Brocade native mode (interopmode 0). Connectivity between M-EOS platforms and a switch running FOS v7.0 or later is supported via FCR.

Port Mirroring

• On the Brocade 5300, the port mirroring feature has a limitation where all port mirror resources must stay within the same ASIC port group. The resources are the configured mirror port, Source Device, and Destination Device or ISL, if the Destination Device is located on another switch. The ASIC port groups are 0-15, 16-31, 32-47, 48-63, and 64-79. The routes will be broken if the port mirror resources are spread across multiple port groups.

• Port Mirroring is not supported on the Brocade 7800.

Port Statistics

• On Condor3-based (16G FC) 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. 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.

Both enc_in and enc_out counters contain valid information when a Condor3-based port is operating at speeds other than

other than 10G and 16G.
