CABH-CAP-MIB Table View

This table contains IP address mappings between private
network addresses, or network addresses and port
numbers/ICMP Identifiers, assigned to devices on the
subscriber's home LAN, and network addresses, or network
addresses and port numbers/ICMP Identifiers on the WAN,
presumed to be on a separate subnetwork than the private
IP addresses.  The CAP Mapping Table is used by the
CableHome Address Portal (CAP) function of the PS to make
packet forwarding decisions.

cabhCapMappingEntry row .1.3.6.1.4.1.4491.2.4.3.1.2.1.1

List of the private IP (LAN) address - to - cable
operator assigned IP (WAN) address mappings stored
in the PS and used by the PS to make packet
forwarding decisions.
