Usage Based Billing (SAMIS)

Cisco IOS Release 12.3(9a)BC introduces the Usage-Based Billing feature on the Cisco uBR7246VXR
universal broadband router, supporting DOCSIS 1.0- and DOCSIS 1.1-compliant cable modems. This
feature provides subscriber account and billing information in the Subscriber Account Management
Interface Specification (SAMIS) format. SAMIS is specified by the Data-over-Cable Service Interface
Specifications (DOCSIS) Operations Support System Interface (OSSI) specification.
For additional information about configuring and monitoring Usage-Based Billing (SAMIS) on the
Cisco uBR7246VXR CMTS, refer to the following document on Cisco.com:

Bidirectional PIM
Cisco IOS Releases-Supported in the Cisco IOS 12.2 BC and 12.1 EC release trains.
Bidirectional Protocol Independent Multicast (bidir-PIM) is a variant of the Protocol Independent
Multicast (PIM) suite of routing protocols for IP multicast. In PIM, packet traffic for a multicast group
is routed according to the rules of the mode configured for that multicast group. The Cisco IOS
implementation of PIM supports three modes for a multicast group:
•
•
•
A router can simultaneously support all three modes or any combination of them for different multicast
groups. In bidirectional mode, traffic is only routed along a bidirectional shared tree that is rooted at the
rendezvous point (RP) for the group. In bidir-PIM, the IP address of the RP acts as the key to having all
routers establish a loop-free spanning tree topology rooted in that IP address. This IP address does not
need to be a router, but can be any unassigned IP address on a network that is reachable throughout the
PIM domain. Using this technique is the preferred configuration for establishing a redundant RP
configuration for bidir-PIM.
