Chapter 2 Cisco CMTS Configuration Commands
cable upstream timing-adjust
To enable upstream timing adjustment for a specified cable interface, use the cable upstream timing-
adjust command in cable interface configuration mode. To return to the default values, use the no form
of this command.
Syntax Description n
continue sec
threshold sec
Defaults 2 seconds for continue and 1 second for threshold
Command Modes
Interface configuration (cable interface only)
Command History Release
11.3 NA
12.0(12)SC
12.1(3)T
12.1(3a)EC
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.
The cable timing-adjust command is applicable only on Cisco IOS Release 12.0(12)SC and Cisco IOS
Note
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.
