Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

A CMTS bridge is a logical entity that serves DHCTs in the same hub. For this reason, create one CMTS bridge
for every hub that serves Explorer 8300 DHCTs. 

Obtain a copy of your network map to ensure you can easily reference the information you need to enable each
CMTS in your system for multicasting. You must also have the following information:



Multicast IP address for each CMTS bridge

Important: A unique IP address that is within the range of addresses reserved for multicasting is
required.



IP address of your Session Resource Manager (SRM)



UDP port number that the DHCT uses to communicate with the SRM

Adding a CMTS bridge takes about 5 minutes.

Adding a CMTS bridge to the DNCS does not impact network performance. You can complete this procedure at
any time.
