Command History
Usage Guidelines
To verify whether or not upstream timing adjustment is configured and activated, enter the
show
running-config
command and look for the cable interface configuration information. If upstream timing
adjustment is enabled, either or both of the
continue
and
threshold
timing adjustment entries are
displayed in the
show running-config
output. If both the
continue
and
threshold
upstream timing
adjustments are disabled, no timing adjustment entry is displayed in the
show running-config
output.
If you are having trouble, make sure that the cable connections are not loose or disconnected; the cable
interface line card is firmly seated in its chassis slot; the captive installation screws are tight; and you
have entered the correct slot and port numbers.
Note
The
cable timing-adjust
command is applicable only on Cisco IOS Release 12.0(12)SC and Cisco IOS
Release 12.1(3)T. It is deprecated and removed on Cisco IOS Release 12.1(3a)EC, 12.1(4)CX, and later
releases.
n
Specifies the upstream port number. Valid values start with 0 for the
first upstream port on the cable interface line card.

sec
Sets the minimum timing adjustment that sets
continue
ranging status
in seconds. The range for
sec
is 2 to 64 seconds. Default value is
2 seconds.

Sets the timing adjustment threshold in seconds. Valid threshold value
is 1 to 32 seconds. Default is 1 second.
