Release Notes

Fabric OS v7.3.0c Release Notes v1.0 Page 9 of 52
two latency severity levels and provide intuitive reporting in MAPS dashboard under a new Fabric Performance
Impact category.
Monitor FCIP statistics
FOS v7.3 supports new monitoring elements (RTT, Jitter) in the FCIP circuit group, adds a FCIP tunnel group to
monitor tunnel state change and throughput, adds 4 FCIP tunnel QoS groups to monitor throughput and packet
loss for each QoS priority. These new monitoring elements and groups are included in MAPS pre-defined
policies and supported only on Brocade 7840.
Monitor fabric scalability limit
FOS v7.3 supports new monitoring elements in the switch group to monitor them against the fabric scalability
limits supported by Brocade. These elements include number of device connections in a layer2 fabric, number
of imported devices in a metaSAN, number of FCRs in a backbone fabric, and zoning database size. These new
monitoring elements are included in MAPS pre-defined policies.
Monitor ClearLink Diagnostic (D_Port) ports
FOS v7.3 supports new monitoring elements for port error statistics (CRC, ITW, PE, LF, and LOSS_SYNC) in a
new D_Port logical group to monitor D_Port tests so that the test results can be determined by thresholds in
the MAPS rules. These new monitoring elements and groups are included in MAPS pre-defined policies.
Monitor Ethernet management port
FOS v7.3 supports monitoring Ethernet management port state in a new Ethernet port group to generate alerts
if states for Ethernet management ports are changed. These new monitoring elements and group are included
in MAPS pre-defined policies.
Monitor Flow Vision learning flows
FOS v7.3 supports importing and monitoring of learning flows created through Flow Vision in MAPS.
Administrators can use this capability to configure thresholds and alerts for application flows without knowing
the source or destination device identities in advance.
Support Port Decommissioning as an action
FOS v7.3 supports port decommissioning as an action that can be triggered by MAPS rules. With port
decommissioning, ports can be gracefully shutdown in the event of violations without I/O interruption. FOS
v7.3 supports port decommissioning on E_Port natively through MAPS. For port decommissioning on F_Port,
Brocade Network Advisor 12.3 is required.
Support dynamic group based on user defined pattern
FOS v7.3 introduces dynamic group to enhance logic group definition for port objects. Administrators can
create custom groups whose membership dynamically changes based on user defined port identity traits.
Support port group augmentation
FOS v7.3 implements port group augmentation to pre-defined groups and dynamic groups so that
administrators can make small adjustments to group memberships without having to create a new group.
Usability enhancements
FOS v7.3 has a number of usability enhancements to MAPS. These include:
• Change mapssam CLI to display system CPU, memory, and flash usage.
• Change mapsrule and logicalgroup CLIs to make deletion of rules and groups easier.
• Add a new option to mapsConfig CLI to send test emails to validate email configuration.
Flow Vision Enhancements
FOS v7.3 has a number of important Flow Vision enhancements to the Flow Monitor, Flow Generator, and Flow
Mirror functionalities.
