FOS v7.3 upgrades a number of important open source software packages (openSSH, openSSL, Apache) to provide stronger security. Access Gateway Enhancements FOS v7.3 implements following Access Gateway (AG) enhancements. ClearLink Diagnostics (D_Port) Support on AG FOS v7.3 supports dynamic D_Port on connections between an AG and an HBA to allow automatically start D_Port test requested by an HBA. User Account and Password Distribution to AG FOS v7.3 supports user account and password database distribution from a native switch to an AG so that user accounts and passwords can be managed the same way as native switches in a fabric. Fabric Device Management Interface (FDMI) Data Access on AG FOS v7.3 adds the support of accessing device information for devices that are registered with FDMI and connected through AGs. Zoning Enhancements FOS v7.3 enhances zoning to disallow two fabrics with empty zoning configuration to merge if one fabric has All Access as default zone access mode and the other has No Access as default zone access mode. This enhancement prevents the fabric with All Access default zone access mode from losing all device connections due to converting to No Access default zone access mode after fabrics merging. High Integrity Fabric FOS v7.3 introduces support of High Integrity Fabric mode to ensure strict and consistent fabric configurations required by a FICON fabric, which include Insistent Domain ID and strict fabric-wide Switch Connection Control policy. Administrators can use the High Integrity Fabric mode to enforce these configurations for a FICON fabric. RAS Enhancements FOS v7.3 implements the following RAS enhancements. Frame Viewer (Class 3 Discard Log) Enhancements FOS v7.3 enhances Frame Viewer to capture two new types of class 3 discard frames. The new discard types captured include destination unreachable frames and unroutable frames. Audit Log for Class 3 Discard Frames FOS v7.3 adds to audit log message for each class 3 discard frame. This ability to allow administrator to configure audit log to send class 3 discard frame messages to a centralized syslog server, which does not have size limitation of a switch Frame Viewer log. Forward Error Correction (FEC) Enhancements FOS v7.3 adds the ability to allow FEC capability negotiation during speed negotiation in Transmitter Training Signal. This ability can be configured by existing CLI command portCfgFec. Firmware Download Enhancement Fabric OS v7.3.0a Release Notes v2.0 Page 12 of 55
