Cisco WAN Manager Overview
Cisco WAN Manager (CWM), a suite of WAN multiservice management applications, provides powerful fault, configuration, and performance management functionality for WAN multiservice switches CWM also provides robust statistics collection, storing the information in an Informix SQL database and allowing simple integration of this data into existing network management and operations systems
Element and network management functions are provided by the CWM system, which can manage Cisco BPX® 8600 and Cisco IGX™ 8400 series wide-area switches and Cisco MGX™ 8220 and
8850 devices seamlessly CWM provides open interfaces for higher level service management systems
The CWM desktop graphical user interface (GUI) provides the following management functions:
• Topology Management and Display
• Statistics Collection Management and Report Generation
• Configuration Management
• Performance Management
• Fault ManagementCWM provides these functions in an open management environment CWM runs on Solaris, AIX, and HP-UX platforms, and integrates with HP OpenView and IBM NetView:
Features
This section provides information about the main features of CWM
Trang 16Operating within the HP OpenView and IBM NetView multi-vendor management environments, CWM supports a suite of open interfaces for access to management information including:
• Standard management integration protocols interfaces, including SNMP
• SQL access to the Informix relational traffic database
• X-terminal access for multiple operators into CWM management agents
• Craft interface for terminals and simple tools WAN multiservice management can be integrated within the multi-vendor environment using third party applications in conjunction with the CWM application Otherwise, integration management interfaces and software tools can achieve fault, configuration, performance and security
management through the open management interfaces
Connection Management
The Connection Manager provides the network manager the ability to add, modify, and delete end-to-end connections The Connection Manager provides a series of forms-based screens to add, modify, or delete connections You select the desired connection end-points and configure the connection type and class of service The end-to-end connection is automatically established without requiring configuration of the network on a switch-by-switch basis In addition, each connection’s status can be viewed from one endpoint to the other
Connection management is one of the most challenging issues in ATM network management; ATM networks support so many connections that it can become impossible to administer and manage them The Connection Service MIB provides integrated automated provisioning of connections based on quality of service parameters, such as the type of connection being made, available bandwidth, and the current state of the network
The Connection Service MIB provides a standard SNMP interface for the WAN ATM network at the service level Service providers who are responsible for managing the entire shared network can use this interface to integrate with automated Operations Support Systems (OSS) provisioning systems and also to provide Customer Network Management (CNM) views and control capabilities on a per-connection basis
CWM Graphical Applications
CWM graphical applications provide value-added functionality to the standard features in the HP OpenView or IBM NetView platforms These forms-based, graphical applications are launched from the management platform to provide intuitive, point-and-click management capabilities
Trang 17Topology Manager
Topology Manager
The Cisco WAN network topology is automatically discovered and presented through HP OpenView
or IBM NetView topology map windows Network element and trunk status is represented by icon color changes dynamically Custom background images can be associated with each network map
to provide a user-defined view of the network Optionally, you can enter node information through the Topology Configurator for stand-alone MGX switches
Statistics Reports Manager
CWM Statistics Reports are generated through a graphical reporting package based on the Informix WingZ application This application provides a point-and-click graphical user interface to generate reports based on information collected by the Statistics Agents For each report, the user identifies the network object, type of statistics, granularity, report interval, and graphical format The report agent queries the Informix database and generates a report in the desired format, such as line, bar, 3D, or tabular chart
Statistics Collection Manager
The Statistics Collection Manager (SCM) provides a forms-based interface to establish and modify statistics collection policies for the network You can configure statistics collection policies such as which statistics to collect and collection interval periods for a node, port, or private virtual circuit (PVC) SCM provides extensive error handling and logging capabilities that enable reliable collection of statistics for performance or billing applications Additional SCM agent workstations can be installed should the load require gathering additional statistics Each SCM agent can collect
in excess of 1 million statistics per hour Scalability of statistics collection is an important differentiator of CWM CWM also provides node utilization reports not based on Wingz
Equipment Manager
The Equipment Manager application provides the capability to configure and manage network equipment including cards, lines, and ports through an intuitive graphical user interface The Equipment Manager application simplifies configuration and diagnostic tasks for Cisco WAN multiservice network equipment
Event Manager
Network faults are integrated with the HP OpenView or IBM NetView Event Browser to enable management of heterogeneous, multi-vendor network environments Through the Event Browser the events can be filtered by a combination of event type, source, message string, time received and severity, grouped into categories based on event severity, or acted-on through custom-defined operator actions Different actions can be configured on a per-node basis such that the same type of event from different sources cause different automatic actions
Security Management
Security Management is a new CWM desktop application that provides controlled access to multiple users of CWM based on the unique user ID and password You can use Security Management to provide individuals access privileges to perform specific tasks such as viewing topology or establishing and managing connections Without the required access privileges, unauthorized users cannot perform any network management functions

Additional Features and Benefits
This section provides information about the other miscellaneous features and benefits of CWM
Access to IGX, BPX, and MGX Networks
IGX, BPX, and MGX switches provide an Ethernet 802.3 AUI LAN interface to CWM for network management control and information An entire network can be managed through an Ethernet connection on a single WAN switch or through multiple Ethernet interfaces distributed throughout the network Cisco WAN switches use TCP/IP over Ethernet to communicate between CWM network management workstations and the WAN switch Telnet support is also available to enable LAN-based workstations access to the IGX, BPX, or MGX management interface
Out-Band Network Management
An entire network can be managed through a connection on a single WAN switch or through multiple interfaces distributed throughout the network Network Management access to the IGX can
be either provided locally through a direct interface or remotely Remote and dial access to any IGX node can be accomplished by connecting a dial modem to the control port All of the security management functions of the IGX, BPX, or MGX platforms are maintained whether access is local
or remote
Virtual Terminal access to any remote IGX from the CWM configuration screen or a VT100 connected to the Control Port is supported using the 'VT' command The 'VT' command will provide network operations staff with identical control and monitoring capabilities as if they were locally attached to the switch
Graceful Software and Firmware Download and Upgrades
Software and Firmware downloading of all operating system and firmware code is fully supported
by BPX, IGX, MGX, and CWM Software and firmware upgrades are performed by loading new code from either a CWM workstation via TCP/IP, a new NPM module, or via dial in from Cisco’s Technical Assistance Center (TAC) New software and firmware are downloaded throughout the network utilizing inter-nodal trunks New code is loaded into the standby NPM card for initiation at
a specified time This new code can be uploaded to all other IGXs in-band through the ATM fabric connecting the switches
Firmware upgrades for a specific function module are performed by first loading the new firmware
code into the NPM Then a command is issued to burn the function module with the new firmware
revision This may take up to ten minutes, during which time the function module is out of service Software upgrades are conducted in background, and then activated network wide The duration of
a software activation is 10 seconds per node on a rolling basis Configuration translation software is provided with software upgrades to automatically migrate existing configuration information into new software releases
Simultaneous upgrades to multiple devices is supported via background loading of new code and simultaneous switching to the new code
During all software and firmware upgrades the current configuration is retained The conversion is automatic and performed by the new software release If a software upgrade is faulty a single command can return the entire network to the previous version software and configuration in ten seconds
Trang 19Configuration Save and Restore
Configuration Save and Restore
The Configuration Save and Restore function enables you to save a snapshot of the entire network's configuration on CWM In a disaster recovery scenario, you can selectively restore a single node's configuration, or restore the configuration of the entire network on a node by node basis This feature significantly reduces time to recover in the unlikely event of a catastrophic failure You can also use the Save and Restore feature to restore a previous configuration after making a series of incorrect or temporary changes
Performance Management
The CWM TFTP statistics collection facility offers extensive usage and error collection A wide range of statistics are available at the port and virtual channel level to support operations and maintenance, customer network management and usage-based billing Historical statistical information is stored in the CWM Informix database The open SQL interface architecture then provides users with direct access to the information stored in the Informix relational database CWM addresses historical information via the SQL architecture because of the large volume of information present in the database and the inefficiencies involved in retrieving it via SNMP

Unique Node ID
Cisco WAN Manager release 9.2 enables you to automatically assign a unique node ID to all nodes
in a network The unique node ID is used to identify nodes in all the different database tables After installing and configuring CWM 9.2, the unique node ID feature will be active when you launch CWM
The unique node ID feature of CWM assigns a node identifier to each node as it is discovered The
node IDs for all existing nodes are saved in the nodes.conf file of /usr/users/svplus/config and in
the node table of the database For all subsequent warm starts (where a database exists from the previous session), the nodes are assigned their previous IDs which were stored in the database
Stand Alone MGX 8850 Configurations
Using the MGX 8850 in stand-alone configurations requires that you disable automatic node ID generation To assign unique node IDs to stand alone nodes, you must disable automatic Node Identification and use the Topology Configurator feature of the CWM desktop application, CWM Admin, to provide all node information, including the unique node identification, before launching CWM The Topology Configurator is described in Chapter 8, CWM Administrator Information about disabling this feature can be found in Disabling Automatic Node ID Generation below
First add the nodes using the Topology Configurator, then click Apply and Notify to force the topology subsystem to read the nodes.conf file All nodes for which a Node ID has been defined
should display on the Topology map
Trang 34Configuring Auto Route Network Discovery
Cisco WAN Manager Operations
3-2
Maintaining the Unique Node ID Feature
To maintain unique Node IDs in your network, you must adhere to the following rules
• Maintain one master copy of the nodes.conf file
• When changes are required, make changes to the master copy, then copy the changed nodes.conf
file to all other CMW stations
• Perform a cold start of CWM if a Node ID requires reassignment
Disabling Automatic Node ID Generation
To disable automatic unique node ID generation, edit the /usr/users/svplus/config/Topod.conf file The third line of Topod.conf describes the next line as the Auto Node Id Generation flag On line four, change the TRUE to FALSE to disable automatic node ID generation
You can use the Topology Configurator to manually assign all node identification information before launching CWM
Configuring Auto Route Network Discovery
Auto route networks are discovered using link protocol Before attempting auto route discovery, you
must first specify all networks to be discovered in the /usr/users/svplus/config.sv file and add the Node ID for all gateway nodes specified in the config.sv file using the Topology Configurator
Modifying the config.sv File
The config.sv file is stored in /usr/users/svplus directory The config.sv file is written with default
values during software installation and can have only one line containing 12 fields separated by a
pipe (“|”) delimiter Following is an example of the contents of the config.sv file:
1 CWM Network ID 0 Unique identifier for a network
2 Network Name Network1 Unique name for a network Limited to 8 characters, no spaces
or meta characters or hyphens
3 CWM Gateway Node
Name/ Serial Port
/dev/ttya Specify the device filename for the serial port used Limited to 8
characters, no spaces or meta characters or hyphens
4 Baud Rate Set 9600 Serial port speed; must match speed of control port at the node
5 Autodial Phone 0 Phone number to dial out including prefix, if needed; 0 if not
dialing out
6 SV_Timeout 7 Link timeout used by svmain (field must not be changed)
7 Retransmit 6 Link retry count used by svmain (field must not be changed)
8 DL_Throttle_TO 0 Download throttling timeout (field must not be changed)
9 DL_Ack_TO 30 Acknowledge timeout for download (for configd)
10 DL_Blk_SIZE 1024 Block size for download (for configd)
Trang 35Displaying the Cisco WAN Manager Network Topology
Note The name of the gateway node specified in the config.sv file must be the same as the name
of the node configured on the switch If the IP address of the node is specified, ensure that the name
resolves to the node name configured on the switch by issuing a ping command using the name
assigned using the Topology Configurator
Adding Node IDs for Gateway Nodes
Add the Node ID for all gateway nodes specified in the config.sv file using the Topology
Configurator You can add the Node ID for other nodes later, perhaps while auto route discovery is taking place
First add the nodes using the Topology Configurator When you have finished adding nodes, click
Apply, then Notify Doing so forces the topology subsystem to read the nodes.conf file All nodes
for which a Node ID has been defined should display on the Topology map
Displaying the Cisco WAN Manager Network Topology
To display the CWM Network Topology window, start the CWM application, enter 3 (Start Desktop) at the Main Menu prompt and press the Return key, then click on the Topology button
