cadBridgeGroupTable

A table (and along with other supported tables)
contains bridge group information. 
A bridge group is actually a Port-Vlan concept
which consists of one or more E-ports and one 
or more D-ports. 
          
Each D-port includes its associated U-ports and is
further subdivided into 3 sub-ports associated with
different types of traffic.  The CM sub-port carries
traffic for the cable-modem itself.  The CPEAUTH sub-port
carries traffic for an authorized CPE behind a cable-modem.
The CPEUNAUTH sub-port carries traffic for an unauthorized
CPE behind a cable-modem.
          
Initially, all ports belong to the OAM&P bridge group when
a card is first provisioned.  Bridge ports can only exist
in one bridge group at a time and can be moved between them.
          
Generally, the CPEAUTH sub-port on the D card would be in a
bridge group with an E port that had access to the internet
and the DHCP servers for the ISP used by the subscriber.
The CM sub-port would be in a bridge group with an E port that
had access to the DHCP servers and administrative controls
for the MSO. The CPEUNAUTH sub-port would be in a bridge 
group that included access to a sign-on server.
