Hello everyone!! I have a question here, I need your help! Recently I bought a Cisco uBR924 and I've been trying to connect it at home, so I can expand my home lab capabilities. My service provider is Time Warner (Road Runner) and I simply can't connect it to the Internet. This router has one cable-modem interface, four ethernet ports (represented as 1 ethernet interface) and two FXS voice-ports.
According to the Cisco's documentation, the service establishment process of a cable-modem-router like this one is as follows: - Scan for a downstream channel and establish synchronization with the CMTS. - Obtain upsteam channel parameters. - Start ranging for power adjustments. - Establish IP connectivity - Establish the time of day - Establish security - Transfer operational parameters - Perform registration - Comply with baseline privacy - Enter the operational maintenance state When I issue "show int cable-modem 0", I notice a lot of "interface resets" displayed by the output. Further investigation required me to run some debug commands and - I love this one - "show controllers cable-modem 0 mac log", which probably identified the problem. I could see almost all "CMAC_LOG_STATE_CHANGE" events, but during the registration process (registration_state), the modem received a "RESET_AUTHENTICATION_FAILURE". I pasted part of the output so my question may be answered by someone: The steps from "scanning downstream" to "establish security" seem to be fine: 1041.159 CMAC_LOG_STATE_CHANGE wait_for_link_up_state 1041.159 CMAC_LOG_STATE_CHANGE ds_channel_scanning_stat 1043.540 CMAC_LOG_STATE_CHANGE wait_ucd_state 1046.319 CMAC_LOG_STATE_CHANGE wait_map_state 1046.371 CMAC_LOG_STATE_CHANGE ranging_1_state 1047.337 CMAC_LOG_STATE_CHANGE ranging_2_state 1048.112 CMAC_LOG_STATE_CHANGE dhcp_state 1048.404 CMAC_LOG_DHCP_ASSIGNED_IP_ADDRESS 10.47.170.200 1048.404 CMAC_LOG_DHCP_TFTP_SERVER_ADDRESS 24.29.99.72 1048.404 CMAC_LOG_DHCP_TOD_SERVER_ADDRESS 24.29.99.72 1048.404 CMAC_LOG_DHCP_SET_GATEWAY_ADDRESS 1048.404 CMAC_LOG_DHCP_TZ_OFFSET 0 1048.404 CMAC_LOG_DHCP_CONFIG_FILE_NAME disabled.bin 1048.404 CMAC_LOG_DHCP_ERROR_ACQUIRING_SEC_SVR_ADDR 1048.404 CMAC_LOG_DHCP_LOG_SERVER_ADDRESS 24.29.99.57 1048.404 CMAC_LOG_DHCP_COMPLETE 1059.956 CMAC_LOG_STATE_CHANGE establish_tod_state 1059.956 CMAC_LOG_TOD_REQUEST_SENT 24.29.99.72 1059.964 CMAC_LOG_TOD_REPLY_RECEIVED 3252376461 1059.968 CMAC_LOG_TOD_COMPLETE 1059.968 CMAC_LOG_STATE_CHANGE security_association_state 1059.968 CMAC_LOG_SECURITY_BYPASSED But when the modem downloaded de DOCSIS configuration (the config file), I noticed something weird: 1059.968 CMAC_LOG_STATE_CHANGE configuration_file_state 1059.968 CMAC_LOG_LOADING_CONFIG_FILE disabled.bin 1063.988 CMAC_LOG_CONFIG_FILE_PROCESS_COMPLETE Did you noticed the filename received by the Cisco uBR924? Its name is "DISABLED.BIN". It doesn't sound good...... After that, the next step is "registration". Now I noticed that the CTMS has, for an "unknown" reason, rejected the registration process. Therefore, the router is unable to proceed with other steps toward the Internet connection. 977.130 CMAC_LOG_STATE_CHANGE registration_state 977.130 CMAC_LOG_REG_REQ_MSG_QUEUED 977.138 CMAC_LOG_REG_REQ_TRANSMITTED 977.142 CMAC_LOG_REG_RSP_MSG_RCVD 977.142 CMAC_LOG_RESET_AUTHENTICATION_FAILURE 977.142 CMAC_LOG_STATE_CHANGE reset_interface_state 977.142 CMAC_LOG_STATE_CHANGE reset_hardware_state I tried to configure this device at both bridge and routing levels, and it didn't work at all. Do you guys know if some ISPs have configured anything that could block "unauthorized devices" (anything not the modem they provide us) to establish internet connectivity? Do they make any kind of MAC addresses filtering? I really don't want to use a plain modem to connect to the Internet. Specially when I have a cool Cisco with a lot of interesting features. Any help would be appreciated.
