WAN CiscoView is the device management platform for all Cisco equipment. WAN CiscoView for the BPX SES PNNI Controller is a JAVA-based software application that allows you to
CiscoView operations are SNMP-based to provide fault and configuration management for all the devices it supports. CiscoView does not support any database, nor does it support unsolicited traps to gather statistics. Rather, it uses a polling mechanism to gather status updates.
When you start the CiscoView application, the CiscoView Main window opens. (See Figure 1-1.)
Use the following procedure to connect to the BPX SES PNNI Controller.
Step 2 Press Return.
The Community String window opens. (See Figure 1-2.)
Step 3 If the community strings are provided, press OK.
If the community strings are not provided, you can enter Read and Write communities (for SNMP GET/SET requests to the device). To connect to a device, you need to know the read community string. If you want to perform configuration tasks on the device, you must also know its write community name.
Step 4 Press OK.
A graphical representation of the BPX SES (Service Expansion Shelf) PNNI Controller (a device labeled CISCO SES Service Expansion Shelf) displays in a configuration window within the CiscoView Main window as shown in Figure 1-3. This is the front view of the PNNI controller.

Note Running multiple instances of CiscoView may slow down performance of your workstation because this requires more RAM. |
The rear view of the device shows the ports, connectors, and LEDs. These are color-coded to display their status. Table 1-1 describes the commonly used colors and their meaning.
To open the rear view, right-click on the device in the area around the cards then select Rear from the popup menu.
| Color | Meaning |
|---|---|
blue | Dormant/OK |
orange | Down |
red | Major Alarm/failure |
yellow | Minor alarm |
purple | Self-test |
green | Up/OK |
The other active components of the CiscoView Main window are the buttons in the lower left corner. The buttons are described in Table 1-2.
The display you see when you first enter CiscoView is of the front panel of the device. You can display configuration windows for the front card or the device by right clicking on the corresponding parts of the graphic (the device configuration window is accessible by clicking anywhere but on an installed card). You can view the configurable categories of information for a card from the available popup menu.
Right clicking away from an installed card will also include options for refreshing and resizing the screen, as well as for system information.
You can change some CiscoView operating characteristics, such as the polling frequency or the number of retries, from the SNMP tab of the User Preferences window. To change the operating characteristics, perform the following steps:
The CiscoView User Preferences window shows tabs used to specify various characteristics: SNMP, Community, Look&Feel, Debug.
Step 2 Enter a value in the Chassis Polling Frequency field (sec) to change the polling frequency. The default value varies by device.
A typical value is every 60 seconds. To disable polling frequency, set the value to zero. If you set the polling frequency below 60 seconds for a number of devices, it may slow down your network. It is advisable to use low polling frequencies in specific testing situations and increase them when you have finished testing. Do not poll faster than every 5 seconds.
Step 3 Enter a new value in the SNMP Timeout (sec) field to change the timeout interval.
A timeout indicates the amount of time it takes to reach a device. If it takes longer than the time specified, the device is considered to be either unreachable or down. The interval value is specified in seconds; the default is 3 seconds.
As a guideline, the timeout value should be set to twice the average end-to-end delay in your network. If you have a network with several slow links, you may need to set the timeout to a higher value. If you have only LAN links in your network, a value of 20 seconds is reasonable to account for processing delays and timer accuracy. In high traffic situations, you may experience timeouts. You should not reduce the polling frequency because this may cause a general error. Increase the timeout interval if you consistently experience timeouts.
Step 4 Enter a new value in the SNMP Retry Count field to change the number of retries. The default value is 3.
The retries value indicates how many times CiscoView retries an unresponsive device. In busy networks, SNMP datagrams can be discarded. The retries value allows the application to continue operation during network problems. A setting of 3 is considered a reasonable value; increase the value if the network is slow.
Step 5 Enter the read or write community string in the appropriate field.
This allows you to enter the write community string for a device after you display the device. This is useful, for example, if you want to make changes to a device or port setting but did not specify the write community string when you first opened the device display. You can enter the write community string in the Write Community field without exiting and reopening the window.
Step 6 Click the Radio button, next to the Show MIB Label As field, to control how parameters will appear in the dialogs or tables.
The Alias option displays text labels; this is the default. MIB textual labels are user-friendly aliases of the MIB descriptor. The Descriptor option displays actual variable names (MIB descriptors) used to manage devices, for example, locIfOutBitsSec, is output bits per second.
Step 7 Click OK to affect the changes you have made in the User Preferences window.
CiscoView displays two primary types of information for devices, cards, and ports:
CiscoView displays different categories of information for each PNNI Controller device or card. To see the categories of information that can be displayed for each component type, look at the Category popup menu on the Configuration or Monitor windows. To display a particular type of information, select the category type.
Use the Configuration menu in the CiscoView Main window to display configuration information, or select Configure from a component popup menu. CiscoView displays configuration information in the Configuration windows. The information is displayed as a list of fields for a single port, or as a table that includes fields for multiple ports.
CiscoView displays performance information from the Monitor menu in the main window. To view performance information, select Monitor from a component popup menu. Performance information is displayed in a dashboard.
To display the Card Configuration dialog for a card, at the rear view, right-click the card (front view), then select Configure from the popup menu.
To display the configuration parameters for a card, select one of the options from the Category pull-down menu at the top of the dialog.
To display the appropriate configuration dialog, at the rear view, right-click on the line or port (connector), then select Configure from the popup menu.
To display the configuration parameters for a particular line/port, select the desired option from the Category pull-down menu at the top of the dialog.
Context-sensitive online help provides you with step-by-step instructions on how to use
WAN CiscoView. The online help system also provides a glossary and keyword search capability.
The following types of information are available from the Help system as follows:
Jumps move you around the Help system and popup windows display for each topic selection. Click a highlighted and underlined topic to jump to a help window for that topic. If you jump to another topic, you have to click Back on the menu bar to return to the previous help topic. You can display a definition of a term which is dotted and underlined by clicking on it; the definition appears in a popup help window. When you go to a popup window, press Enter to return to your previous help topic.
Each help window has a menu bar and a button bar. The menu bar provides standard help functions for printing help topics, copying and pasting text from help topics, making online notes about particular help topics, and placing bookmarks.
The button bar provides the following buttons:
Many Help Topics windows have Overview and See Also links. Select the Overview link to obtain background information for the procedure described in the Help window. Select the See Also link to display a list of related topics and go directly to those topics. View topics from the current Help Topics window.
To exit Help or Help Topics, select File>Exit on the menu bar in the Help window.
