Table8 Show Controllers Cable-Modem MAC State Field Descriptions
Field Description
MAC State Current operational state of the MAC layer of the Cisco uBR924.
Ranging SID Service ID used for ranging requests.
Registered Indicates whether or not the Cisco uBR924 is currently registered with the CMTS.
Privacy Established Indicates whether or not keys for baseline privacy have been exchanged between the
Cisco uBR924 and the CMTS, establishing privacy.
Mac Resets Number of times the Cisco uBR924 reset or initialized this interface.
Sync lost Number of times the Cisco uBR924 lost synchronization with the downstream
channel.
Invalid Maps Number of times the Cisco uBR924 received invalid MAP messages.
Invalid UCDs Number of times the Cisco uBR924 received invalid UCD messages.
Invalid Rng Rsp Number of times the Cisco uBR924 received invalid ranging response messages.
Invalid Reg Rsp Number of times the Cisco uBR924 received invalid registration response messages.
T1 Timeouts Number of timeouts caused by the Cisco uBR924 not receiving a valid upstream
channel descriptor (UCD) from the CMTS within the specified time.
T2 Timeouts Number of timeouts caused by the Cisco uBR924 not receiving a maintenance
broadcast for ranging opportunities from the CMTS within a specified time.
T3 Timeouts Number of timeouts caused by the Cisco uBR924 not receiving a response within a
specified time from the CMTS to a RNG-REQ message during initial maintenance.
T4 Timeouts Number of timeouts caused by the Cisco uBR924 not receiving a response within a
specified time from the CMTS to a periodic maintenance request.
Range Aborts Number of times the ranging process was aborted by the CMTS.
DS ID Identifier of the downstream channel on which this MAC management message has
been transmitted. This identifier is arbitrarily chosen by the CMTS and is only
unique within the MAC-sublayer domain.
DS Frequency Downstream frequency acquired by the Cisco uBR924 during its last initialization
sequence.
