Authorize the BRF as a BFS Server (Optional)
Introduction
In systems that use a DOCSIS
®
return path for DHCT communications, there is no
support in the cable modem termination system (CMTS) for the downstream
channel descriptor (DCD). These systems need a Bridge Resolution File (BRF) to use
as a BFS server in order to enable DHCTs to discover their hub ID and MAC layer
multicast address. After an upgrade, the system does not automatically authorize the
creation of the BRF as a BFS server; you must authorize the file creation manually.
Follow these instructions to inspect the BFS GUIs for the presence of the BRF and
then to authorize the file, if necessary.
