4-70
slot is the slot number of the DOCSIS module on the BSR 64000
interface is the number of the cable interface
n is the SID number for the CM
The SM Exhausted Count value in the command output refers to the number
of times a CM was dropped because it did not reply to station maintenance
requests.
The SM Aborted Count value in the command output refers to the number of
times the CM was dropped because of unacceptable operating parameters.
This can occur if the power level is outside the acceptable range, or the timing
offset changes. The command output indicates the times when this occurs.
CM is Offline
If a CM is offline, it is disconnected from the network and unable to register.
Ping the CM to determine if the connection between the cable interface and the
CM is online. A CM may appear to be offline if it does not have an IP address and
is not registering; however, it may still be online. Pinging is necessary when the
following symptoms occur:
• CM is unable to complete registration.
• CM has internal bugs.
• CM is unresponsive due to a crash.
The ping feature includes a real-time view and plot of requested power
adjustments. It also measures the optimal headend reception power that allows the
cable interface to solicit a configurable number of periodic ranging requests from a
CM.
Note: The BSR 1000 uses the same syntax as the above command,
however both the slot number and interface number are set to zero.
