Chapter 2 Cisco Cable Modem Termination System Commands
Note The show controllers clock-reference command might display compare errors on the Cisco uBR10012
router because there could be a slight delay at system startup before the TCC+ cards synchronize with
each other. These initial compare errors can be ignored and cleared with the cable clock clear-counters
command.
Most of the information shown by the show controllers clock-reference command is in the form of a
hexadecimal bitfield that is not meaningful for normal operations, but the following fields can be useful
in troubleshooting problems with the TCC+ and cable interface line cards:
UCPC Bus Control Status Reg—Displays the status of both TCC+ cards and whether the LCD
Display Panel is present.
Line Card Presence Status Reg—Provides a software view of whether a cable interface line card is
physically present in the Cisco uBR10012 chassis.
LC Presence Input Reg—Provides a hardware view of whether a cable interface line card is
physically present in the Cisco uBR10012 chassis.
LC Power off Status Reg—Indicates whether a cable interface line card slot has been powered off
using the cable power command.
Table 2-31 shows how to interpret these fields.
