  Viewing the Address Family (IPv6) Profile
Viewing the PIM Profile
PIM is a family of multicast routing protocols for Internet Protocol (IP) networks that provide 
one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet. It is termed 
protocol-independent because PIM does not include its own topology discovery mechanism, but instead 
uses routing information supplied by other traditional routing protocols such as the Routing Information 
Protocol, Open Shortest Path First, Border Gateway Protocol and Multicast Source Discovery Protocol. 
There are four variants of PIM:
PIM Sparse Mode (PIM-SM)
PIM Dense Mode (PIM-DM) 
Bidirectional PIM
PIM source-specific multicast (PIM-SSM) 
Although PIM is called a multicast routing protocol, it actually uses the unicast routing table to perform 
the Reverse Path Forwarding (RPF) check function instead of building up a completely unrelated 
multicast routing table. PIM does not send and receive multicast routing updates between routers like 
other routing protocols.
To view the PIM profile:
Step 1Right-click on the required device and choose the Inventory option.
Step 2In the Inventory window, choose Logical Inventory>Multicast>PIM. The profile details are 
displayed in the content pane. You can click on the tabs to view more details.
Table 23-5 describes the fields that are displayed in the PIM profile. Group Ranges Tab
Group Range The multicast group range in CDIR format, which is basically the 
Multicast Group IP address followed by the CDIR prefix.
Protocol The PIM protocol that is used by the IGMP group range.
Table 23-4 IGMP Profile Details (continued)
Field Name Description
Table 23-5 PIM Profile Details
Field Name Description
NSF Status The non-stop forwarding status, which can be Normal or Non-Stop 
Forwarding Activated.
NoteThe Non-Stop Forwarding Activated status implies that recovery 
of an IGMP failure is in progress.
Interfaces Tab
Interface Name The name or ID of the interface on which PIM is enabled.
Associated Entity The link to the associated entity, which when clicked will highlight the 
associated Default routing entity record under the Routing Entity 
node.

IP Address The IP address of the interface.
VRF The name of the VRF associated to the interface. This is a link, which 
when clicked will take you to the relevant record under the VRF node.
PIM Status Indicates whether the PIM is enabled (ON) or disabled (OFF) on the 
interface.
Hello Interval The frequency at which PIM hello messages are sent over the PIM 
enabled interfaces. 
These messages are sent at regular intervals by routers on all the PIM 
enabled interfaces. The router sends these messages to advertise their 
existence as a PIM router on the subnet.
Designated Router The IP address of the designated router on the LAN.
NoteSerial 4.3.2 do not have a designated router. Hence, the IP 
address is displayed as 0.0.0.0. If the interface on the router is 
the designated router, then the words “This system” is displayed. 
If not, then the IP address of the external neighbor is displayed.
Designated Router 
PriorityThe priority of the designated router, which is advertised by the 
neighbor in the hello messages. This value in this field will range from 
0 to 4294967295.
Rendezvous Points Tab
RP Address The address of the interface serving as a rendezvous point for the group 
range or list.
A Rendezvous Point (RP) is a router in a multicast network domain that 
acts as a shared root for a multicast shared tree. Any number of routers 
can be configured to work as RPs and they can be configured to cover 
different group ranges. For correct operation, every multicast router 
within a Protocol Independent Multicast (PIM) domain must be able to 
map a particular multicast group address to the same RP.
Mode The PIM protocol mode for which the router is advertised as a 
rendezvous point. The mode can be PIM-SM or bidirectional PIM.
Scope The number of candidate announcement messages sent out from the 
rendezvous point.
Priority The value of the candidate rendezvous point priority.
Uptime The amount of time from when the rendezvous point is available.
Group List The IP access list number or name of the group prefixes that are 
advertised in association with the rendezvous point address.
RP Type The type of rendezvous point, which can be BSR or Au t o R P.
NoteThe Bootstrap Router (BSR) is a mechanism for a router to 
learn RP information. It ensures that all routers in the PIM 
domain have the same RP cache as the BSR. Au t o -R P is a 
mechanism to automate distribution of RP information in a 
multicast network. The Auto-RP mechanism operates using two 
basic components, the candidate RPs and the RP mapping 
agents.

Managing Session Border Controllers (SBCs)
This chapter identifies and describes the properties for Session Border Controllers (SBCs) that appear 
in the Vision client logical inventory. It also describes commands you can run to manage SBCs.
Session Border Controllers (SBCs) control and manage real-time multimedia traffic flows between IP 
network borders, handling signaling, and media. SBCs perform native IP interconnection functions 
required for real-time communications such as admission control, firewall traversal, accounting, 
signaling interworking, and quality-of-service (QoS) management. This includes:
Protocol and media interworking
Session routing
Hosted Network Address Translation (NAT) and firewall traversal
Security and AAA
Intra- and inter-VPN interconnections and optimization
Media transcoding with an external media server
The Prime Network platform provides fault management, configuration, and performance monitoring for 
SBC services. Prime Network SBC commands allow you to configure SBC components.
An SBC consists of combined DBE and SBE functionality:
Data Border Element (DBE)—Responsible for media-related functions.
Signaling Border Element (SBE)—Responsible for call signaling-related functions. 
In addition, the SBC can operate in the following deployment models:
Distributed Model (DM)—Contains only the SBE or DBE, resulting in a distributed SBC. 
Unified Model (UM)—Contains both the SBE and DBE, thereby implementing the SBE and DBE 
as a single device. 
NoteThe existing Cisco SBC platforms support only DBE. 
The following topics describe the SBC properties that are displayed in the Vision client logical inventory. 
If you cannot perform an operation that is described in these topics, you may not have sufficient 
permissions; see Permissions for Managing SBCs, page B-20.

An SBC policy is a set of rules that define how the SBC treats different kinds of VoIP events. An SBC 
policy allows control of the VoIP signaling and media that pass through the SBC at an application level.
A policy set is a group of policies that can be active on the SBC at any one time. If a policy set is active, 
the SBC uses the rules defined within it to apply policy to events. Multiple policies can be set on a single 
SBC.
