Description: The sysUpTime value when the trunk was last changed to the current status.
What is lportTrkLastTimeChange?
This records the sysUpTime at which the trunk last transitioned into its current lportTrkStatus value, functioning like an ifLastChange analog scoped specifically to trunk state. An admin uses it to determine trunk stability, since a trunk whose lportTrkLastTimeChange is recent despite the device having a long uptime suggests the trunk just flapped. For example, if sysUpTime shows the device has been up for 30 days but lportTrkLastTimeChange indicates the trunk state changed only 5 minutes ago, that trunk clearly just went through a status transition worth investigating.
