managers a complete view of Cisco products without physically checking each device at remote sites.
" Oriented for exception reporting, enabling users to access essential inquiry information quickly.
" Shows a continuously updated physical picture of routers, hubs, switches, or adapters.
" Can be invoked several times in the same session to simultaneously support multiple switches, routers, hubs,
or adapters.
" Scrollable viewing for use with large devices such as the Catalyst 5500 and Cisco 7500.
CiscoView can run on UNIX workstations as a fully functional, independent management application. It is also
available in Windows 95 and NT format on a PC. In addition, CiscoView can be integrated with the following
SNMP-based network management systems to provide a seamless, powerful network view:
" Sun Microsystems SunNet Manager
" Hewlett-Packard OpenView
" IBM NetView for AIX

CWSI
CWSI is a GUI-based device management software application that provides a suite of integrated tools to provide
topology management, traffic management, VLAN management, management of ATM networks, and user
tracking.
Topology Management Services
The topology displays provided by CWSI include both physical and logical layer topology views of Cisco
switches and routers. CWSI uses the information contained in CDP advertisements to draw a map of the
discovered devices, including Catalyst Token Ring switches. From these maps, you can launch other CWSI
functions.
As an integral component of the topology management, CWSI offers logical viewing and configuration services
for many of the Catalyst Layer 2 functions, such as spanning tree design and analysis. Network operators can
easily select any one of, or a multiple of, these functions with the new topology display service module. This
service module customizes the view to a specific feature and then allows the operator to undertake guided
configuration functions.
These display and configuration functions are accomplished by simply selecting the Catalyst features to be
managed. CWSI highlights the appropriate configuration details on top of the physical map and offers
configuration selections in which modifications can be made. Critical information, such as the root bridge within
a calculated spanning tree, are all provided as part of these services.
Traffic Management Services
The traffic management services of CWSI allow you to monitor your enterprise networks from a central site, to
ensure high network reliability and availability.
The traffic management services work as a distributed system by using a central management console running
the software in conjunction with data-gathering agents located at various points on a network. It can
simultaneously collect wide-ranging statistical data, display selectively captured and fully decoded network
traffic, set user-defined alarm conditions, and get real-time updates from all segments of a widely dispersed
internetwork.
The traffic management services are based on two standards that let them operate in a multi-topology,
multivendor environment:
" SNMP defines the protocol for all intercommunications between the traffic management services and
SwitchProbe devices.
" RMON MIB, which defines the type of information that the agent gathers that is available for you to display
for each network segment.
The traffic management services provide functions for the following:
" Monitoring network traffic and measuring the flow of data
" Capturing network traffic and recording it for later examination
" Interpreting raw network data and translating it into a graphic form that you can view and analyze
" Setting limit conditions on network traffic and generating alarms if those limits are exceeded
11-2 Catalyst Token Ring Switching Implementation Guide
Network traffic information is collected from RMON agents in devices running Cisco IOS software, SwitchProbe
standalone network monitoring probes, or any RMON standards-compliant agent. Performance and fault
management are also simplified by multilayer traffic analysis, proactive alarms, remote packet capture, and
protocol decode features.
VLAN Management Services
The VLAN management services of CWSI allows you to configure, manage, and monitor interconnected Cisco
switches and routers. Integral components of the VLAN management services include graphical mapping utilities
for viewing and configuring logically defined workgroups, drag-and-drop port-level configuration options for
assigning users to VLANs, automated link assignment settings for managing VLANs campus-wide, integration
with common SNMP management platforms for consolidating system resources and detailed reporting functions
for maintaining audit trails.
The benefits of VLAN management services include:
" Accurate campus view of Cisco switches and routers simplifies VLAN configuration and monitoring functions.
" On-screen reports of VLAN device, link, and port status are quickly obtained using pop-up windows and icon
highlighting. Audit trails can then be generated from these reports.
" Drag-and-drop graphical configuration options provided by CiscoView minimize the skill level required to set
up and assign ports to VLANs.
" A simplified VLAN naming window and associated directories offer flexibility and easy-to-use search functions
for creating and changing VLAN names.
" User-selectable options for configuring VLANs across interswitch backbones include selecting multiple paths,
choosing specific paths based on preferences, and manually adding and deleting paths.
" Logical views of configured VLANs include switch, link, and port membership windows, enabling users to
audit and verify membership status.
User-selectable color options concurrently display multiple configured VLANs, making it easier to visualize and
identify VLAN configurations.
ATM Management Services
The ATM management services of CWSI provides:
" Comprehensive discovery of ATM devices that support ILMI
" Virtual circuit setup and trace analysis of both PVCs and SVCs
" The launching of Cisco's graphical device management application from any of the Cisco icons within the
topology map
" A real-time path trace analysis tool for checking end-to-end connectivity
Additional enhancements to the ATM management functionality in CWSI include performance analysis of the
LANE components, configurations functions for PNNI routing, and traffic monitoring capabilities with ATM
RMON. As part of the LANE management features, network managers can quickly check the status of the LECS
database with a graphical representation on the location of this database within the ATM fabric, and they can
query this database for ELAN-to-MAC and ELAN-to-network service access point (NSAP) address mappings.
This information provides an address list of the end stations within each ELAN. Further, network managers can
select the LES database and discover the MAC-to-NSAP address mappings to resolve network addresses. For
redundancy, network managers can configure a backup LECS in conjunction with Cisco's SSRP for increased
reliability. The ATM management functions provide utilities for synchronizing the database for naming
consistency and integrity.

As part of the PNN configuration options, network managers can set administrative weightings and topology
metrics to better optimize the communication across the ATM fabric. Further, network managers can view the
PNNI-routed topology by selecting this display option within the topology map manager.
