Description
Current operational state of the MAC layer of the Cisco uBR924.
Service ID used for ranging requests.
Indicates whether or not the Cisco uBR924 is currently registered with the CMTS.
Indicates whether or not keys for baseline privacy have been exchanged between the
Cisco uBR924 and the CMTS, establishing privacy.
Number of times the Cisco uBR924 reset or initialized this interface.
Number of times the Cisco uBR924 lost synchronization with the downstream
channel.
Number of times the Cisco uBR924 received invalid MAP messages.
Number of times the Cisco uBR924 received invalid UCD messages.
Number of times the Cisco uBR924 received invalid ranging response messages.
Number of times the Cisco uBR924 received invalid registration response messages.
Number of timeouts caused by the Cisco uBR924 not receiving a valid upstream
channel descriptor (UCD) from the CMTS within the specified time.
Number of timeouts caused by the Cisco uBR924 not receiving a maintenance
broadcast for ranging opportunities from the CMTS within a specified time.
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.
Number of timeouts caused by the Cisco uBR924 not receiving a response within a
specified time from the CMTS to a periodic maintenance request.
Number of times the ranging process was aborted by the CMTS.
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.
Downstream frequency acquired by the Cisco uBR924 during its last initialization
sequence.
