This object reports the object identifier of the specific MIB table that was modified, as part of a configuration-change trap. Administrators use it to identify exactly which table on the device changed when a csOrionConfigChange trap fires, without having to poll the whole device to find the change. For example, receiving a trap where this object points to the pseudowire VC table would tell an engineer that a VC entry, not some other configuration, triggered the change notification.
