Cisco cBR 8 Configuration Guide

Enabling Default DOCSIS 1.0 ToS Overwrite
All CMs with a DOCSIS 1.0 configuration file currently have their ToS overwrite default values are set to
tos-and: 0xff and tos-or: 0x00. Since there were previously no mechanism in the DOCSIS 1.0 configuration
file to specify the ToS overwrite, QoS profiles were created and assigned to the default ToS overwrites.
The following procedures enable the Default DOCSIS 1.0 ToS Overwrite feature, which will allow a default
ToS overwrite to be bound to all CM created profiles.
Before You Begin
There are no prerequisites for these procedures.
Note
•
The Default DOCSIS 1.0 ToS Overwrite feature is only applicable to CMs running DOCSIS version
1.0.
•
Once the Default DOCSIS 1.0 ToS Overwrite feature is configured, all CMs will need to be reset
in order for the effect to take place.
•
Once the Default DOCSIS 1.0 ToS Overwrite feature is configured, all CMs will display the default
values that were configured. After which, overwrite values can only be changed by editing the QoS
profiles.
