The following features supported in FOS v7.3 and earlier releases are obsolete beginning with FOS v7.4:
•Fabric Watch
•Advanced Performance Monitoring (APM)
Users running Fabric Watch for switch monitoring in FOS v7.3 are advised to convert to MAPS monitoring before upgrading to FOS v7.4. Converting Fabric Watch to MAPS before upgrading to FOS v7.4 can preserve Fabric Watch threshold configurations. If users choose to upgrade to FOS v7.4 without converting to MAPS, Fabric Watch will stop functioning after the firmware upgrade and the Fabric Watch thresholds cannot be automatically migrated for use by MAPS. Please refer to the Fabric OS MAPS Administrator’s Guide for step-by- step migration instructions.
Users running APM in FOS v7.3 are required to remove all monitors before upgrading to FOS v7.4 by using the following commands:
Fabric OS 7.4.0a Release Notes v2.0 |
Page 8 of 53 |
1.Enter perfdeleemonitor to remove all End-to-end monitors.
2.Enter perfcfgsave to save this change.
3.Enter fmmonitor --delmonitor to remove all filter monitors.
4.Enter fmmonitor --delete frametype to remove the specified user-defined frametype.
5.Enter perfttmon --delete to remove all switch level Top Talker monitors.
6.Enter perfttmon --delete fabricmode to remove fabric mode Top Talker monitors.
After upgrading to FOS v7.4, the APM monitors will stop functioning. Users can use the Flow Vision features as part of Fabric Vision for performance monitoring. Please refer to the Fabric OS Flow Vision Administrator’s Guide for detailed instructions on removing APM monitors and Flow Vision feature configurations.
Brocade Fabric Vision licenses are required for MAPS and Flow Vision. The combination of Brocade Fabric Watch license and Brocade APM license enables the MAPS and Flow Vision features.

New Feature Descriptions
New Hardware Support
FOS v7.4 adds support for the following new hardware:
•Brocade-branded 4GB external USB flash drive
IP Extension features for Brocade 7840
FOS v7.4 introduces IP Extension support for the Brocade 7840. Users can use this capability to extend IP storage for replication and disaster recovery in much the same way as Fibre Channel storage while taking advantage of the compression, encryption, QoS, and trunking features available in the Brocade 7840.
A Brocade 7840 running FOS v7.4 can support both FCIP Extension and IP Extension at the same time. IP Extension includes the following:
•Support for system configuration for IP Extension
•Support for GbE port configuration for IP Extension
•Tunnel configuration for IP Extension
•Adaptive Rate Limiting
•TCP/IP Features
•Traffic Control List
Support System Configuration for IP Extension
FOS v7.4 supports users configuring Brocade 7840 for both FCIP Extension and IP Extension (hybrid mode). By default, Brocade 7840 supports FCIP Extension only. Changing a Brocade 7840 between FCIP-only and hybrid mode requires a switch reboot.
Support GE Port Configuration for IP Extension
FOS v7.4 supports users configuring the front end 1/10 GbE ports as LAN ports on a Brocade 7840 for hybrid mode. These ports are used to connect to IP storage devices on the LAN side. FOS v7.4 supports static Link Aggregation Group (LAG) configuration so that multiple LAN ports can be assigned to the same LAG group.
Tunnel configuration for IP Extension
FOS v7.4 supports user configuration of IP tunnels on a Brocade 7840 in the same way as FC tunnels are configured. IP tunnels and FC tunnels are all represented under virtual E-port (VE). Each VE is configured as a FC-only tunnel or as both FC and IP tunnels. Trunking, QoS, and compression are supported on IP tunnels as they are for FC tunnels.
Adaptive Rate Limiting (ARL)
FOS v7.4 supports all ARL features available on the FCIP Extension for IP Extension. The static distribution of unused bandwidth is hierarchical.
TCP/IP Features
FOS v7.4 supports the following TCP/IP features for IP Extension.
•LAN side jumbo frames
•IPv4 and IPv6 for LAN side
•Maximum 512 TCP connections per Data Processor (DP)
•Maximum 512 TCP open requests per second per DP
•Maximum 64 UDP flows per DP
•DSCP/VLAN L2CoS marking
•Segment Preservation
•Each LAN TCP window will be 64K by default. If TCP window scaling is requested, the maximum advertised window is 256K. The maximum window per connection is 2M irrespective of the advertised window.
Fabric OS 7.4.0a Release Notes v2.0 |
Page 10 of 53 |
•Untagged and single tagged packets are supported.
•Stacked/double (IEEE 802.1ad) tagged packets from hosts are not supported. Packets will be dropped.
Traffic Control List
FOS v7.4 supports Traffic Control List (TCL) to manage and route IP flows. Each TCL is identified by a unique user configured name. FOS v7.4 supports maximum 128 TCLs. System generated default TCL will drop all the incoming packets.
FCIP Enhancements to Brocade 7840
Base Switch Support for 7840
FOS v7.4 enhances Virtual Fabric support on 7840 switches to include the base switch, i.e., to support XISL. Users can configure E_port (ISL over FC), EX_port (IFL over FC), and VE_port (ISL over GE) in base switch. The maximum number of logical switches supported — including the base switch — remains four.
FCIP Hot Code Load (HCL)
FOS v7.4 enhances FCIP HCL support in the following conditions, which were excluded in FOS v7.3.
•Support concurrent FCIP HCL on all 7840 switches in the configuration
•Support multiple sites for FCIP HCL
Monitoring and Alerting Policy Suite (MAPS) Enhancements
FOS v7.4 has a number of important MAPS feature enhancements. These include:
•Basic monitoring without Fabric Vision license
•Monitor NPIV device login limits
•Monitor backend ports
•Monitor FCIP circuit QoS
•Monitor FCIP circuit RTT and jitter on Brocade 7800 and FX8-24 blade
•Fabric Performance Impact monitoring enhancement
•Slow drain device quarantine action for Fabric Performance Impact monitoring
•Port toggle action
•FICON notification action
•Alert quiet time support
•Usability enhancements
Monitoring without Fabric Vision license
FOS v7.4 introduces a new basic monitoring capability in MAPS. The basic monitoring capability allows end users without Fabric Vision licenses on their switches to use MAPS to monitor overall switch status, FRU health, and switch resource categories under the new pre-defined MAPS policy dflt_base_policy.
Monitor NPIV device login limits
FOS v7.4 introduces MAPS monitoring of NPIV login limits. FOS has limits on the number of NPIV devices that can login to a physical F_port. MAPS monitors the percentage of logged in NPIV devices relative to the maximum number of NPIV logins allowed on the F_port to alert users before the limit is reached.
Monitor backend ports
FOS v7.4 introduces back-end port error monitoring in MAPS. Users can take early recovery actions if any of the monitored back-end errors have crossed specified thresholds. Typical recovery actions include SerDes tuning on a switch or reseating blades. For detailed instructions on these actions, please contact your support provider for additional assistance.
Fabric OS 7.4.0a Release Notes v2.0 |
Page 11 of 53 |
Monitor FCIP circuit QoS
FOS v7.4 enhances FCIP QoS monitoring in MAPS to add monitoring of Fibre Channel QoS parameters at circuit level. The circuit QoS monitoring combined with the tunnel QoS monitoring available since FOS v7.3 provides additional granularity to monitor the FCIP link performance.
Monitor FCIP circuit RTT and jitter on 7800 and FX8-24
MAPS monitors circuit round trip time (RTT) and jitter statistics in FOS v7.3 on Brocade 7840. FOS v7.4 supports these two FCIP circuit monitoring elements on Brocade 7800 and FX8-24 blade so that they are available to 8G FC extension platforms.
Fabric Performance Impact monitoring enhancement
FOS v7.4 enhances Fabric Performance Impact (FPI) monitoring to add a new IO_LATENCY_CLEAR state so that end users can receive notification when latency conditions are cleared. FOS v7.4 enhances FPI monitoring by adding latency counter monitoring on all ports to detect potential transient spikes of latency conditions. In addition, FOS v7.4 moves port TX, RX, and UTIL monitoring systems to the FPI category from the Port Health category in FOS v7.3 and earlier releases so that all potential congestion conditions are reported under the FPI category.
Slow drain device quarantine action for Fabric Performance Impact monitoring
FOS v7.4 introduces a new MAPS action that automatically isolates slow drain devices when they are detected by FPI monitoring. This frees up buffer credits for normal devices that are sharing the same links and mitigates the effect due to presence of slow drain devices in the fabric.
Port toggle action for Fabric Performance Impact monitoring
FOS v7.4 introduces Port Toggle as an action which automatically recovers slow drain device conditions when they are detected by FPI monitoring. A port toggle, (which is a port disable followed by a port enable) can recover the ports from some slow drain device conditions or force traffic failover to an alternate path.
FICON notification action
FOS v7.4 introduces FICON notification as a new action that enables MAPS events to be sent to FMS with detailed event information upon rule violations. FMS CUP can translate these MAPS events into FICON-specific Health Summary Check reports.
Alert quiet time support
FOS v7.4 introduces a quiet time support for RASLOG and EMAIL alert actions. This feature allows end users to configure within a rule a period of time not to receive duplicated alerting actions after the first alert has already been sent.
Usability enhancements
FOS v7.4 has a number of usability enhancements to MAPS. These include:
•Allow none to be used as an email address to clear previously configured email addresses in the CLI command mapsconfig.
•Enhanced Temperature Sensor monitoring so that actions are triggered on change of Temperature Sensor (TS) states.
•Modified FRU monitoring so that the states being monitored are more accurate and useful for operations.
•An upper limit to the number of rules that can be created in a policy. The maximum number of rules in a policy is dependent on the character length of each rule name.
Flow Vision Enhancements
FOS v7.4 provides the following enhancements to Flow Vision:
All F_Port Flow Monitoring
FOS v7.4 introduces a system predefined learning flow named sys_mon_all_fports to monitor performance on all F_ports in a switch. Flow learning on all F_ports provides a continuous, automatic, and comprehensive view of application traffic patterns for all device connections.
Fabric OS 7.4.0a Release Notes v2.0 |
Page 12 of 53 |
Scalability Improvement
FOS v7.4 increases the scalability limit supported by Flow Vision. In particular, the total number of sub-flows supported by chassis switches is increased to 2048 and by fixed port switches is increased to 512.
Identify All Devices in a Flow
FOS v7.4 supports displaying all zoned devices in a flow by introducing a new option -allzoned to the Flow Vision command. This will identify all zoned devices for a flow defined on an E_Port or F_Port.
Fabric Flow Dashboard
FOS v7.4 introduces support of a Flow Dashboard that provides information for a flow from all the available data points in the fabric through which it can pass. With all relevant data summarized for a flow of interest, users are able to more easily troubleshoot and identify the root cause of various issues that may occur.
ClearLink Diagnostic (D_Port) Enhancements
FOS v7.4 implements the following D_Port feature enhancements.
Link Power (dB) Loss Calculation
FOS v7.4 supports calculating TX and RX power loss of a link with D_Port tests. D_Port tests include the power loss calculation to provide additional details on the health of physical media of links.
Dynamic D_Port and On-demand D_Port with DWDM
FOS v7.4 enhances D_port pre-provision feature to allow administrators to pre-provision certain ports connected to DWDM links. With the pre-provisioned list, dynamic D_port and on-demand D_port tests can start automatically on those ports with the optical loopback test skipped.
CLI Command Hierarchical Help Display
FOS v7.4 enhances the help page for D_port CLI commands so that only the relevant sub-options are displayed when a command action is specified for the portCfgDport and portDportTest commands.
Peer Zoning Support
FOS v7.4 introduces support for Peer Zoning as defined in the FC-SW-6 and FC-GS-7 standard. In a Peer Zone configuration, membership in a zone is differentiated into principal members and non-principal or peer members. Peer Zoning configuration allows communication between a principal member and any peer member but does not allow communication between two peer members or between two principal members. By adopting Peer Zoning, users can simplify zoning configuration and management, improve performance, and increase scalability.
Target Driven Zoning support
FOS v7.4 introduces the Target Driven Zoning feature that allows end devices to create Peer Zone configurations through inband commands. This feature enables zoning to be configured by management software on storage devices and reduces the manual configuration needed on switches.
Lossless DLS enhancement
FOS v7.4 introduces a routing enhancement to support lossless Dynamic Load Sharing (DLS) in a 2-hop topology. This enhancement allows adding links or switches in existing paths that are up to 2 hops between a host and a target, including the new link that is coming online, to ensure lossless and in-order frame delivery.

FCR enhancements
FOS v7.4 has a number of enhancements in FCR. These enhancements include:
Location Embedded LSAN zone
FOS v7.4 introduces the location-embedded LSAN zone feature. A location-embedded LSAN zone specifies in the LSAN zone name the remote fabric ID that shares devices. The corresponding FCR switch will use this information in the LSAN zone names to store only these entries for the locally connected edge fabric. As a result. users are now able to configure more LSAN zones across a backbone fabric.
Increase Number of Imported Proxy Devices
FOS v7.4 increases the maximum number of proxy devices that can be imported into each edge fabric to 4000. This limit applies to the cumulative number of all proxy devices created on all translate domains in the edge fabric. FOS versions prior to v7.4 support 2000 proxy devices as the limit for this number.
Sort WWNs in lsanzoneshow CLI
FOS v7.4 supports sorting WWNs in the CLI command lsanzoneshow output. A new -o or -sort option is added to the CLI command to display entries in sorted order by WWNs for each LSAN zone listing.
Support Port Range for portcfgexport and portcfgvexport CLI
FOS v7.4 supports port range as input parameters for the portcfgexport and portvexport CLI commands so that multiple ports can be configured as EX-port or VEX-port at the same time.
Support Peer Zoning with FCR
FOS v7.4 supports Peer Zoning in LSAN zones if users have configured a peer zone in an edge fabric. Peer zoning rules and RSCN distribution will be enforced by edge fabric switches.
Support New Domain ID Range for Front and Translate Phantom Domains
FOS v7.4 supports assigning for an FCR the front domain ID in the range of 160 through 199 and the translate domain ID in the range of 200 through 239. Users can use the CLI command fcrConfigure -- resetPhantomDomain to use the new range to avoid conflicting with the real switch domain IDs.
Security Enhancements
FOS v7.4 has a number of important security enhancements:
Obfuscation of RADIUS Shared Secrets
FOS v7.4 supports obfuscation of the RADIUS shared secrets so that they are not stored as plaintext. With this option, stored shared secrets are not visible as plaintext in configUpload files and SupportSave files.
Import/Export Syslog Server Certificates
FOS v7.4 adds the support of importing and exporting a syslog server certificate to support syslog over TLS. A syslog server CA certificate can be imported from a remote host or exported to a remote host.
Password Policy Enhancement for Root Password Change
FOS v7.4 adds a new option in the switch account password policy to allow root password change by root account login sessions without prompting for the existing (old) password.
secCryptoCfg CLI Command
FOS v7.4 supports a new CLI secCryptoCfg command to configure the set of acceptable cryptographic algorithms for the SSH and HTTPS protocols on a switch. Administrators can use this new CLI command to mandate various cryptographic algorithms conform to their policies.
Default Account Password Change
FOS v7.4 modifies the behavior of default switch account password change. Login to admin account would only prompt changes to the default admin and user account passwords. The default root and factory account passwords change would only be prompted when login to the switch as root.

Time Server Enhancements
FOS v7.4 enhances Time Server to support Network Time Protocol (NTP) server configuration distribution to Access Gateway switches. This enhancement allows AGs, including cascaded AG connections, to receive the same NTP server configuration from a connected fabric.
SNMP Enhancements
FOS v7.4 implements the following SNMP enhancements.
Log Messages for SNMPv3 Authentication
FOS v7.4 logs SNMP authentication success and failure as audit log messages to track the authentication results for SNMPv3 requests.
SNMPv3 Individual Inform Tag
FOS v7.4 enhances SNMPv3 configuration to allow SNMP informs to be enabled or disabled at individual receiver host level. With this enhancement, users can configure some receivers to get SNMP informs, while other receivers get SNMP traps.
Disable SNMP Write Access
FOS v7.4 changes the default SNMP configuration to have SNMP write disabled. This affects the default switch configuration loaded with FOS v7.4 on a new switch from factory.
Obsoletes Fabric Watch and Advanced Performence Monitoring MIBs
FOS v7.4 obsoletes the following MIBs associated with Fabric Watch and Advanced Performance Monitoring feature: swFwSystem, swBlmPerfMnt, swTopTalker.
RDP Enhancements
FOS v7.4 enhances the Read Diagnostic Parameter (RDP) support which includes the following:
•Enable polling to refresh RDP data cache at a default 4 hour interval.
•Include signal power loss information in the sfpShow --link or sfpShow --pid options.
•Include corrected and uncorrected FEC blocks in portShow --link or portShow --pid options.
Firmware Download Enhancements
FOS v7.4 introduces the following important enhancements for firmware download.
Staged Firmware Download
FOS v7.4 supports staged firmware download so that users can download firmware package to a switch first and choose to install and activate the downloaded firmware at a later time.
Firmware Clean Installation
FOS v7.4 supports firmware clean installation. This installs a firmware package without retaining the existing configuration or maintaining HA. With this feature, customers receiving a new switch from factory can install firmware in a single step to the desired version that their networks are running, without going through multiple steps of non-disruptive firmware download.
Firmware Auto Sync Enhancement
FOS v7.4 enhances the firmware auto sync feature to support automatic synchronization of firmware versions on a standby CP with a version different from the active CP. If an active CP runs FOS v7.4 or higher:
•A standby CP with firmware version as early as FOS v6.4 can be upgraded automatically.
•A standby CP with firmware version later than FOS v7.4 can be downgraded automatically.

Firmware Integrity Check
FOS v7.4 introduces a firmwareCheck CLI command to check the integrity of firmware packages already installed on the switch. If any of the files or packages as part of firmware has been changed, the firmware integrity check will fail and notify users which package has failed the check.
Challenge-Response Authentication
FOS v7.4 introduces support for SSH servers configured with “keyboard-interactive” as defined in IETF RFC 4256 as authentication method to be used with SCP or SFTP for firmware download, support save, and config upload/download commands. With this SSH server configuration, FOS v7.4 only supports account passwords as a form of challenge-response authentication.
RAS Enhancements
FOS v7.4 supports the following RAS enhancements:
WWN Card Replacement Enhancements
FOS v7.4 enhances the procedure for field replacement of WWN cards in chassis based systems. WWN cards are chassis FRUs that contain chassis WWNs and other information. Each chassis has two WWN cards for redundancy. FOS v7.4 enhances WWN card handling so that certain error or data corruptions associated with WWN cards can be recovered in the field.After users replace a single defective WWN card with a new one, some data can be restored from the current/non-defective WWN card to the newly replaced WWN card. In addition, the system periodically checks the integrity of the WWN cards and logs RASLOG error messages if problems are detected.
Show RASLOG Messages within a Timeframe
FOS v7.4 adds options to errdump and errshow CLI command so that only RASLOG messages within the specified beginning and end time will be shown, instead of all RASLOG messages.
Audit Log Enhancements
FOS v7.4 enables audit log by default for all classes of messages. FOS v7.4 increases the maximum number of audit log messages stored on a switch to 1024 from 256.
Clihistory Identify Command Virtual Fabric FID
FOS v7.4 enhances cliHistory so that FID contexts will be shown along with the command line. With this enhancement, clihistory in a support save file includes the FID information for support and debug usage.
Zoning Enhancements
FOS v7.4 adds the following enhancements to standard zoning to simplify zoning configuration:
List Zones with Specific Alias
FOS v7.4 adds support to zoneshow command to display only the zone configurations that match a given alias instead of the entire zone database. Administrators can use this enhancement to quickly locate certain zone configurations that contain a specific alias or alias prefix.
Sort zoneShow Command Output by WWN
FOS v7.4 enhances the zoneShow --sort command output in sorted order for both (D,I) and WWN members.
Indicate offline members in zoneShow output
FOS v7.4 provides a new option --validate to the zoneshow command to indicate members in the configuration but not online in the fabric. Administrators can use this enhancement to quickly discover the online and offline members in a zone configuration.
Traffic Isolation (TI) Zoning Enforcement enhancement
FOS v7.4 enhances TI zoning rule enforcement so that devices connected to the same local switch are also enforced by the TI zoning rule.
