CiscoWorks2000 Voice Management Features

Campus Manager

The ANI discovery process added the support for voice components of the

Cisco AVVID network in Common Management Framework (CMF)

Release 1.1.1. This CMF release supports the following voice devices and

functions:

• Cisco CallManager

Cisco CallManager Release 3.0 (and later) contains the CDP driver, and it

supports partial CDP MIB and SNMP. This is the “tell” side of CDP, so it is

always an edge device, and it displays as a Cisco CallManager icon in the

topology map.

• Cisco IOS voice gateways

The voice gateways are discovered in the same way as regular routers.

• Cisco IP Phones (models 7960, 7940, and 7910)

Cisco IP Phones contain the “tell” side of the CDP driver, but they do not

support SNMP.

• VLAN management

This feature provides tools for graphical VLAN configuration and logical

topology mapping.

• End-station mobility and tracking

This feature provides tools for mobile user and dynamic VLAN tracking and

configuration.

• Trace path analysis

This feature traces Layer 2 and Layer 3 paths between two devices or end

stations using IP address or directory number.

Because there are usually many Cisco IP Phones installed on a network, the ANI

must handle the discovery of Cisco IP Phones separately to avoid overcrowding

the network topology map. For this reason, CMF Release 1.1.1 ignores the CDP

cache entries of the Cisco IP Phones in the neighboring switches and does not

create any device objects for them; hence, daisy-chained IP phones are not

discovered. The Cisco IP Phones are treated as end user devices and are

discovered through User Tracking discovery, as described in the next section.
