Provisioning
Ambit/Broadcom private MIBs provide extensive
support for configuring and controlling PacketCable
NCS based eMTAs where additional functionality has
been added to software above and beyond CableLabs
and other industry specifications. Ambit and
Broadcom’s private enterprise MIBs for Cable data
products(1.3.6.1.4.1.4684/1.3.6.1.4.1.4413.2) currently
consist of the class of devices adhering to Cablelabs
and Excentis specifications for DOCSIS, PacketCable,
and eDOCSIS based devices. Normally the MIB
definitions themselves provide a good overview and
enough information for understanding the purpose and
how to control objects but additional details will be
provided where appropriate. Throughout the
descriptions to MIB objects are references to
interfaces. Ambit’s software can support 8 IP stacks or
interfaces. The assignments of IP addresses is
different if an ePS is included in conjunction with an
eMTA but for the purposes of this document the follow
assignment shows the combined functionality of
DOCSIS or a cable modem along with an eMTA:
• IP Stack (1) = Cable Modem’s public WAN IP
address
• IP Stack (2) = eMTA public WAN IP address
• IP Stack (3) = Cable Modem’s private LAN IP
address 192.168.100.1
