Page 9: Fos V7.4 Obsoleted Fos Features
vTap supports automatic discovery of Analytic F_Port (AF_Port) when a Brocade Analytics Monitoring Platform is attached to the fabric. An AF_Port is a mirror port on the Analytics Monitoring Platform designated as the destination of information sent from vTap-enabled ports on a fabric switch.
Page 10: Fos V7.4 New Feature Descriptions
FOS v7.4 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.
Page 11: Traffic Control List
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.
Page 12: Monitor Fcip Circuit Qos
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.
Page 13: Scalability Improvement
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.
Page 14: Fcr Enhancements
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.
Page 15: Time Server Enhancements
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.
Page 16: Sort Zoneshow Command Output By Wwn
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”...
Page 17: Ti Failover Disabled Zone Message
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.
Page 18: Portstatsshow Command Display Txq Latency
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).
