Table 13 debug cable mac Command Field Descriptions

Field Description

SID value is.... Reports the service ID of the modem. The range is from 1 through

891. The information on this line should agree with the ﬁrst line of

the return (that is, Ranging Modem with Sid...).

CM mac address.... The MAC address of the speciﬁed cable modem.

Timing offset is.... The time by which to offset the frame transmission upstream so the

frame arrives at the expected minislot time at the CMTS.

Power value is FE0, or 0 dB The raw value derived from the 3137 Broadcom chip. Alternately,

the dB value speciﬁes the relative change in the transmission power

level that the cable modem needs to make so transmissions arrive at

the CMTS at the desired power level. This desired power level is

usually 0, but you can use the CLI to change it via the cable

power-level command.

Freq Error = .... The raw value derived from the 3137 Broadcom chip.

Freq offset is ....

Speciﬁes the relative change in the transmission frequency that the

cable modem will make to match the CMTS.

Command Description

show controllers cable Displays interface controller information for the speciﬁed slot.
