Audit Log Messaging Enhancements
Many enhancements are added in the 11.4 release regarding the logging of events. These include:
■In previous releases, only one SYSLOG server on the network could be sent the audit log messages from an Enterprise OS device. With 11.4, the administrator can configure each Enterprise OS device to send it's audit log messages to up to six SYSLOG servers.
■In previous releases, only one SYSLOG server on the network could be sent the audit log messages from an Enterprise OS device. With 11.4, the administrator can configure each Enterprise OS device to send it's audit log messages to up to six SYSLOG servers.
■Persistent logging of events across reboots now available across all platforms. Previously this feature was available only for NETBuilder II and PathBuilder S5xx devices (those devices which could support the partial dump feature). With 11.4, the partial dump feature is extended to the stackable devices (OfficeConnect NETBuilder, SuperStack II NETBuilder SI, and PathBuilder S400 devices), so reasons for spontaneous failures will be logged both on the device and within audit log messages sent to the SYSLOG server(s).

■A new message format will have identifying labels. The new syntax is as follows:
priority Seq:SeqNumber Sev:Severity From:Entity/Source Msg:Text
Changes to audit log messages saved on the device's local audit log buffer:
■The new message format will have identifying labels. The new syntax is as follows:
<priority> Seq:SeqNumber Date/Time Sev:Severity From:Entity/Source
Msg:Text
■Audit Log Message Filters are now supported. In previous releases, all audit log messages were sent to the designated SYSLOG server. With 11.4, the administrator can set a LogFilter, whereby specific messages can be sent to specific SYSLOG servers. Messages can be filtered based on service, priority,
