mnHistTimestamp
Module: MAC-NOTIFICATION-MIB
OID (symbolic): MAC-NOTIFICATION-MIB::mnHistTimestamp
OID (numeric): 1.3.6.1.4.1.13464.1.2.3.3.1.1.1.8.1.3
Node type: OBJECT-TYPE
Type: TimeStamp
Access: read-only
Description: The value of sysUpTime when the mnMacChangedNotification containing the information denoted by the mnHistMacChangedMsg object in this entry was generated.
What is mnHistTimestamp?
This read-only value records sysUpTime at the moment the mnMacChangedNotification associated with this mnHistoryTable entry was generated. An admin uses it to determine exactly when a logged MAC learn or remove event occurred relative to device uptime, which helps correlate history entries with other time-stamped logs. For example, comparing mnHistTimestamp values across consecutive entries lets the admin see how tightly clustered a burst of MAC changes was in time.
