These states correspond to output fields displayed when the show cable modem summary command is issued (such as IP Compl and Dclr). init(i) Cable modem is in the IP-complete state (IP Compl). A cable modem enters this state after the CMTS receives a registration request from the cable modem containing an IP address (TLV Type 12 or 20). The cable modem can transition to this state only from the ranging-complete state. init(r1) Cable modem is in the declared state (Dclr). A cable modem enters this state after the CMTS receives the cable modem s initial ranging request. init(r2) Cable modem is in the ranging state (Rng). A cable modem enters this state during its initial ranging. init(rc) Cable modem is in the ranging-complete state (Rng Compl). A cable modem enters this state after it has completed its initial ranging. 213

If a cable modem goes offline for more than 24 hours, it is removed from the CMTS and briefly enters the destroyed state. A cable modem enters the ranging-aborted state after the CMTS aborts the ranging (initial or periodic) in its ranging response. online Cable modem is in the registration-complete state (Reg). A cable modem enters this state after the CMTS sends an okay registration response (DOCSIS 1.0) or receives an error-free registration acknowledgment (DOCSIS 1.1) from the cable modem. reject Cable modem is in the access-denied state (Access Denied). A cable modem enters this state after one of the following conditions occurs: A cable modem times out before responding to an upstream channel change request. The CMTS responds to a DCI-REQ message with a DCI-RSP message containing a confirmation code set to reject-permanent. The cable modem s registration process fails. You can identify rogue cable modems by the presence of one of the following appended to the Online State field: rc The cable modem was statically configured as rogue by the operator. rt The cable modem was declared rogue by the CMTS because it was not provisioned using DHCP and TFTP before registration. ru The cable modem is presumed to be unprovisioned. Timing Offset Timing adjustment sent to the cable modem by the CMTS in the initial ranging response. Units are 6.25/64 microseconds. Rec Power Measured receive power level (in dbmv) of the cable modem. An asterisk (*) next to the power level indicates the cable modem s power has drifted beyond +/ 3 db from the commanded power level and a power adjustment has been made by the CMTS to bring the power back to within 3 db. An exclamation point (!) next to the power level indicates the cable modem has reached its maximum transmit power level. QoS QoS profile ID. BPI Baseline privacy status. It can be On or Off. IP-Address IP address of the cable modem. MAC-Address MAC address of the cable modem. Reg DOCSIS version of the cable modem as registered with the CMTS. It can be 1.0 or 1.1. Modul Upstream burst modulation format (always TDMA).
