exclamation point (!) in the Receive Power column indicates that the CM has reached its maximum
power transmit level and cannot increase its power level further. An exclamation point (!) in the Timing
Offset column indicates that the CM has exceeded the maximum delay and timing offset specified by the

A pound sign (#) in the MAC State column indicates that the
has been used to require that a CM attempt a TFTP download of the DOCSIS configuration file before
registering, but the CM did not do so (Cisco IOS Release 12.1(11b)EC1 and Cisco IOS
Release 12.2(8)BC2 or later releases).
The following example shows typical output for the show cable modem vendor summary command,
displaying the total numbers for each vendor and OUI, along with the total numbers of those vendor's
CMs that are currently registered with the CMTS, unregistered, or offline.

Description
The cable interface line card providing the upstream for this CM.
The current state of the MAC layer (see
The primary SID assigned to this CM.
The received power level (in dB) for the CM.
An asterisk (*) in the RxPwr column indicates that a power

adjustment has been made for that CM. An exclamation point (!)
indicates that the CM has reached its maximum power transmit level
and cannot increase its power level further.
The timing offset for the CM, in ticks, as recognized on the CMTS. (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.
An exclamation point (!) in the Timing Offset column indicates that

by the

The timing offset shown here is typically smaller than the TX Time

Offset value shown by the
command, because the latter value is the offset as recognized on the
CM (which will include any internal delay between when the CM
software begins the transmission and when the bits actually appear on
the local cable interface).
Indicates the number of CPE devices for which the CM is providing services.
Indicates whether Baseline Privacy Interface (BPI) or BPI Plus (BPI+)
encryption is enabled for the CM.
