Purpose
Sets the interval between successive sync message transmissions in milliseconds.
Default Access Level
15
Command Syntax
configure interface cable-mac <mac> cable sync-interval <milliseconds>
configure interface cable-mac <mac> cable sync-interval [<milliseconds>] no
Supplemental
Information
The sync messages allow a cable modem to lock into the 10.24 MHz system clock in the C4 CMTS. The recommended value for this
parameter is 10 msec.
Decreasing the sync interval causes additional overhead because more sync messages are sent. But increasing the sync interval may
prevent some cable modems from locking onto the system clock. According to the DOCSIS® RFI specification, the maximum time
between sync messages should be 200 msec.
To restore the default value, use the no option.
Parameters
<mac>
The MAC identifier. Valid numbers are 0-415.
<milliseconds>
Valid range for interval is 1 to 200 milliseconds.
Default is 10 milliseconds.
