This read-write TruthValue controls, for the whole interface range in swIfPortLockIfRange, whether an SNMP trap is generated in locked mode. Admins use it to enable violation alerting across a batch of ports in a single configuration action rather than configuring trap settings on each port individually. For example, enabling this across an entire range of secured access ports ensures the admin gets notified regardless of which specific port in that range experiences an unauthorized-device event.
