Abstract
An example method involves generating a table to store current reroute statistics based on rerouting of data from one or more logical circuits, when they have failed, to one or more logical failover circuits. The current reroute statistics include trap data received for the one or more logical circuits. The trap data includes a committed information rate. Each of the logical circuits and logical failover circuits is identified by a logical circuit identifier that is renamed until the one or more logical circuits have been restored. The table is updated to store updated reroute statistics that include updated trap data received for the one or more logical circuits. Generating the updated reroute statistics comprises detecting a change in a status of the one or more logical circuits by determining if a frame has been dropped. The frame is dropped when the committed information rate has been exceeded.
