acsDefaultCpeUser and acsDefaultCpePassword testvars when trying to access this URL. For example, a CPE with a default username of 'cpeurl' and password of 'cpe123' would be configured as follows:
testvaracsCpeDefaultUsercpeurl testvaracsCpeDefaultPasswordcpe123
If the testvar acsDeviceDiscovery is set to 'yes', CDRouter can automatically set the CPE Connection Request URL username and password during the first CWMP session. This will ensure that the username and password match.
