Symptom:
When checking the output rate for a bundle, the result is significantly higher then the sum of max traffic for all RF channels assigned to this bundle. Customer never do RP and LC switch over.
For example, customer real traffic is about 5Gbps on a bundle interface, but after a few days or hours, they found the bundle rate suddenly turns to 100Gpbs or more higher. Then the bundle rate goes down to 5Gpbs  within a few minutes.
Customer configured resiliency, and first found on SCG5. It also found SCH and SCI images in lab by manually do resiliency test.

Conditions:
1) Bundle interface with MAC domains assigned to it (normal CMTS configuration)
2) With no PRE switch over and LC switch over.
3) Configured dynamic resiliency Wideband interface, and modem switch over to resiliency wideband interface.
4) Or manually run resiliency test, such as run command "test cable cm-status bcc8.1087.d858 1 2 0103040106".
