Understanding Show Command Responses
– offline time—the time the CM went offline; the format is the same as other show cable modem
commands (month, day, time, and year).
– init (r1)—CM sent initial ranging.
– init (r2)—CM is ranging.
– init (rc)—CM ranging complete.
– init (d)—Dhcp request received.
– init (i)—Dhcp reply received; IP address assigned.
– init (o)—Option file transfer started.
– init (t)—TOD exchange started.
– online—CM registered, enabled for data.
– online(d)—CM registered, but network access for the cable modem is disabled.
– online(pk)—CM registered, BPI enabled and KEK assigned.
– online(pt)—CM registered, BPI enabled and TEK assigned.
– reject (m)—CM did attempt to register; registration was refused due to bad MIC.
– reject (c)—CM did attempt to register; registration was refused due to bad COS.
– reject (pk)—KEK modem key assignment rejected.
– reject (pt)—TEK modem key assignment rejected.
• Rec Power column contains the nominal receive power in decibels for this SID.
Note An asterisk (*) means that the noise power adjustment method is active for this modem. An
exclamation point (!) means that the modem has reached its maximum transmit power.
• The QoS column contains the service class assigned to the modem.
• The CPE column identifies the number of devices behind the modem.
• The Max CPE column identifies the maximum number of devices configured for the modem.
• The IP address reveals the modem’s IP address.
• The MAC address reveals the modem’s MAC address.
• The Concatenation column reveals if concatenation is enabled (yes) or disabled (no).
• The Rx SNR column reveals the SNR ratio level in dBmV as perceived by the CM.
Note This parameter is only meaningful for CMs. A CMTS returns a zero.
• The S/N Ratio column provides values for remote-queried modems.
• The US Power column reveals the transmit power level for the upstream channel in dBmV.
• The DS Power column reveals the received power level at the downstream modem in dBmV.
Note If the power level measurement is not supported, set this parameter to zero. Also, if the
interface is down, this value will be the CMTS-configured value, the most current CM value,
or zero.
