For telco-return CMs, the ToD server verifies that the IP address for the CM making the ToD request is
on the correct cable interface, so as to prevent IP spoofing. If the IP address and interface do not match,
the following message is printed:
000104: Jun 8 05:48:08.783: tod: Cant match output i/f for telco return
