Table 2-23 Descriptions for the Default show cable modem remote-query Fields
show cable modem remote-query
Field Description
IP Address The IP address that the DHCP server has assigned to the CM.
MAC Address The MAC address for the CM.
S/N Ratio The current signal-to-noise ratio (SNR) on the downstream, as seen by the
CM.
US Power The current operational transmit power level, in dBmV, as seen by the CM.
DS Power The received power level, in dBmV, as seen by the CM. This field is set to
zero if the CM does not support power level measurements.
TX Time Offset The timing offset for the CM, in ticks, as recognized on the CM. (A tick, as
used here, is 6.25/64 microseconds.) This is the delay between when a
particular cable modem is scheduled to make a transmission and when the
CMTS actually receives it. The CM value includes any internal delay between
when the CM software begins the transmission and when the bits actually
appear on the local cable interface.
Note The timing offset shown here is typically larger than the Time Offset
value shown by the show cable modem command, because the latter
value is the offset as recognized on the CMTS (which does not
include the internal delay on the CM).
Micro (dB) Reflection The approximate number of total microreflections (including in-channel
reponses) on the downstream, measured in dBc below the signal level, as seen
by the CM.
Modem State The current state of the MAC layer for the CM (see Table 2-22 on
page 2-370).
The following example shows typical output from the show cable modem remote-query command
when the remote-query feature has not been configuerd.

Tip In Cisco IOS Release 12.1(12)EC, 12.2(8)BC1, and later releases, you can add a timestamp to show
commands using the exec prompt timestamp command in line configuration mode.
