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.
