Time Server Enhancements - ADTRAN NetVanta 7100 IP PBX Configuration Manual

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.
