This read-create TPRowStatus manages, per its source description, the lifecycle of this notification host table entry, accepting active(1) to indicate the row is in use, createAndGo(4, the default) to create and immediately activate a new entry, or destroy(6) to remove an existing entry. Admins use createAndGo to quickly provision a new IPv4 notification host entry in a single SNMP SET operation, or destroy to remove a host that should no longer receive notifications. For example, setting this to destroy(6) for a decommissioned NMS server would remove that entire notification host entry from the switch.
