Chapter 2 Cisco Cable Modem Termination System Commands
Table 2-21 Descriptions for the Default show cable modem Fields (continued)
Field Description
Timing Offset 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.
Note An exclamation point (!) in the Timing Offset column indicates that
the CM has exceeded the maximum delay and timing offset specified
by the cable map-advance command.
Note The timing offset shown here is typically smaller than the TX Time
Offset value shown by the show cable modem remote-query
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).
Num CPEs Indicates the number of CPE devices for which the CM is providing services.
Number of CPE IPs Indicates the maximum number of IP addresses assigned to CPE devices
behind this CM, as configured by the cable max-hosts command.
Ver Displays the maximum supported version of DOCSIS that the CM supports
(DOCSIS 1.0 or DOCSIS 1.1).
Prov Displays the version of DOCSIS that the CM currently is provisioned for
(DOCSIS 1.0 or DOCSIS 1.1).
BPI Enbld Indicates whether BPI or BPI+ encryption is enabled for the CM.
Vendor The vendor for the indicated CM, as specified by the cable modem vendor
command.

MAC State Value Description
Registration and Provisioning Status Conditions
init(r1) The CM sent initial ranging.
init(r2) The CM is ranging. The CMTS received initial ranging from the Cm and has
sent RF power, timing offset, and frequency adjustments to the CM.
init(rc) Ranging has completed.
init(d) The DHCP request was received. This also indicates that the first IP broadcast
packet has been received from the CM.
init(i) The DHCP reply was received and the IP address has been assigned, but the
CM has not yet replied with an IP packet.
init(o) The CM has begun to download the option file (DOCSIS configuration file)
using the Trivial File Transfer Protocol (TFTP), as specified in the DHCP
response. If the CM remains in this state, it indicates that the download has
failed.
init(t) Time-of-day (TOD) exchange has started.
