Hello all. I have a problem with Cisco 7970. At startup this device asks for CTL (Certificate Trust List) file, and startup process stops. I am even can't boot this device. Does anyone know how to avoid this problem? It is said that in older versions of SCCP dummy file with the name CTLSEP<mac addr>.tlv placed to TFTP can solve this problem, but in newer versions it doesn't work. Please help!
