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.
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.
• 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.
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.
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.
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.
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.
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.
TI Failover Disabled Zone Message FOS v7.4 adds a RASLOG message ZONE-1060 to warn users if the TI zone dedicated path is the only path available between two domain IDs. FICON Enhancements FOS v7.4 adds the following FICON related enhancements : MAPS notification to FMS CUP FOS v7.4 supports a new MAPS FICON notification action. With this action, MAPS rule violations can trigger notifications to the FMS host as Health Summary Code reports. ConfigUpload and ConfigDownload of FMS Mode FOS v7.
portStatsShow Command Display TXQ Latency FOS v7.4 enhances the portStatsShow CLI command to display the ASIC transmit queue (TXQ) latency information for each virtual channel (VC). Support De-bouncing of Loss of Signal for Fixed Speed and Auto Negotiate Ports FOS v7.4 expands loss of signal de-bouncing for both fixed-speed and auto-negotiated ports in any port state. FOS v7.4 adds a “mode 2” option for the portcfglosstov CLI command to enable for both fixed-speed ports and auto-negotiate ports.
Optionally Licensed Software Fabric OS v7.4 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 license key upgrade.

• If FOS v7.2 or later is factory installed (or by firmwarecleaninstall), 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. o Ports will come up in AE mode by default o 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.
Logical Switches and the Default Switch. Any Gen 5 ports (Condor3 based) assigned to that Logical Switch will be configured with that Logical Switch’s EHT setting. Any 8G ports (Condor2 based) will continue to share the EHT value configured for the Default Switch. For more information on EHT behaviors and recommendations, refer to the Brocade SAN Fabric Resiliency Best Practices v2.0 document available on www.brocade.com.
FCIP (Brocade 7800 and FX8-24) • Any firmware activation will disrupt I/O traffic on FCIP links. • Latency measurements supported on FCIP Tunnels: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 frames coming with a VLAN tag equal to the configured native VLAN are dropped. • The Converged Network Adapter (CNA) may lose connectivity to the 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 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.
• The FCOE10-24 can handle 169 small FCoE frames in bursts. If you are using the 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 –disable slot/port switch:admin>fcoe --enable slot/port • When a FCOE10-24 blade is powered off during configuration replay, the interface specific configuration won’t get applied.
FL_Port (Loop) Support • FL_Port is not supported on FC16-32, FC16-48, FC16-64, FC8-32E, FC8-48E, Brocade 6510, Brocade 6505, Brocade 6520, or Brocade 7840. • 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 48port or 64-port blade assigned to a non-Default Logical Switch operating with the default 10-bit addressing mode (they may not be in the default Logical Switch).
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.
• It is important to note that the outputs of slotshow –p and chassisShow commands also display the maximum allowed power consumption per slot. These are absolute maximum values and should not be confused with the real-time power consumption on 16G blades. The chassisshow command has a “Power Usage (Watts):” field that shows the actual power consumed in real-time on 16G blades.

Appendix: Additonal Considerations for z Systems (FICON) Environments New Features Support Not all possible combinations of features and hardware configurations are included in the FICON qualification process. Features and hardware configurations not supported for FICON may be supported for open systems environments. This appendix articulates those features and configurations tested for FICON environments and include supplemental information for users deploying FOS-based platforms in FICON environments.
• If you are using the portCfgEportCredit command, a maximum of 16 buffer credits can be configured on all the ICL ports when all the 16 ICL ports are in the disabled state. After enabling all the ports, until the buffer credits are available, the ports will come up with the configured buffer credits. The remaining ports will come up in degraded mode. In case of remaining QoS-enabled ports, the ports will come up without QoS enabled.
ALL to re-balance the E_Port load on a particular logical switch or on all the logical switches, without waiting for a topology change to occur. When the Dynamic Load Sharing (DLS) is disabled, Lossless Dynamic Load Sharing (DLS) is not supported and the E_port Balance Priority feature also gets disabled; but the E_port Balance Priority can be enabled even if the DLS is in Off state. The E_port balance priority is supported on the following z Systems qualified platforms at FOS 7.4.
• To connect between a switch and an HBA at 16 Gbps, both sides must be in the same mode (fixed speed, and FEC on or off) for them to communicate at that rate. If only one port has FEC enabled, neither port will be able to see the other. If the ports are in dynamic mode, then they may connect, but not at 16 Gbps.
• Between Brocade 16 Gbps capable HBAs (Catapult2) Host Bus Adapters and an F_Port. The HBA must be running v3.2 or later and the switch must be running Fabric OS v7.1.0. FEC is compatible with QoS, Credit Recovery, and Fabric-Assigned Port WWM (FA-PWWN). FEC is not supported on D_Ports configured with Dense Wavelength Division Multiplexing (DWDM). The TTS mode is supported only for F_Ports. If a port initializes as an E_Port, it is disabled with a warning message and its peer port will be in "No_Light".
Enabling the insistent domain ID To enable the insistent domain ID, complete the following steps for each switch in the fabric: 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the configure command and step through the interactive prompts. a. At the "Fabric parameters" prompt, type y. b. At the "Insistent Domain ID Mode" prompt, type y. Creating and activating the SCC policy Creating a switch connection control (SCC) policy defines switches allowed in the fabric.
a. At the "Fabric parameters" prompt, type y. b. At the "High Integrity Fabric Mode" prompt, type y. If HIF configuration requirements have not been met, an error message describes what you must configure for the command to succeed. For example, the following message states that an IDID, SCC policy or fabric-wide consistency policy have not been configured for the switch. Perform additional configuration if required, then enable HIF mode. Error: Unable to set HIF Mode.
