Overview of CiscoView Wireless

CiscoView Wireless (CV) is an SNMP-based device management software application with which you can configure and monitor information for Cisco Internetworking Products.

CiscoView Wireless runs in two distinct modes:

• Stand-alone

• Client/server

About the Stand-Alone Version

The stand-alone version of CiscoView Wireless is a Windows application. All components of CiscoView Wireless and its support software are on the same system and communicate directly with the managed devices.

CiscoWorks for Windows (CWW5.0) suite includes the stand-alone version of CiscoView Wireless.

For detailed information on CWW 5.0, refer to the Cisco Works Windows 5.0 documentation, or go to:

http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/cwfw/cw_5_0_1/index.htm

About the Client/Server Version

CiscoView Wireless runs as a client applet within a browser. The server component of the client server is called CD One. A CiscoView Wireless client can talk to a managed device by using the server. The client/server version is available for two different operating systems:

• Solaris

• Microsoft Windows NT.

Because the CiscoView Wireless client runs within a browser, you can run the client on Solaris and Microsoft Windows operating platforms.

For documentation on CD One 3rd Edition and CiscoView Wireless client that runs on CD One, go to:

http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/cw2000/cw2000_d

Note   CiscoView Wireless Quick Reference Guide describes only the client/server version of CiscoView Wireless that runs on the Solaris operating system.

About Point-to-Multipoint (P2MP) Radio Line Card Support

In an operational system, a wireless link is established between a point-to-multipoint (P2MP) radio line card in a Cisco uBR7200 series universal broadband router at one end and a complementary P2MP radio line card in a Cisco 26xx or a 36xx series router at the other end. CiscoView Wireless supports the P2MP line card on the following three platforms:

• Cisco uBR7200 series universal broadband routers

• Cisco 26xx series routers

• Cisco 36xx series routers

The P2MP radio line card supports two views:

• Physical

• Logical

As a radio line card starts a wireless interface, you can see the physical appearance of the radio line card and its real-time status in the physical view. The wireless line card also starts one over-the-air downstream channel and multiple over-the-air upstream channels, which appear in the logical view as tangible connectors.

These connectors look and behave like physical connectors and provide access to the characteristics of downstream and upstream channels supported by the line card. You can switch between the physical and logical views by using menus associated with the line card.

For example, Figure 1 shows the physical view for a Cisco uBR7200 series router with two P2MP radio line cards in slots 2 and 3. Each line card has:

• External clock references.

• Input: Shows whether an external clock reference is connected to the line card.

• Output: Shows whether the line card is acting as a clock reference.

• The monitor and power feed panel (PFP) connectors for the main and diversity antenna.

• The various LEDs on the line card.

Figure 2 shows the logical view of the P2MP headend line card in the Cisco uBR7200 router and shows the downstream and upstream channels supported by the line card.

About Headend P2MP Line Cards

Table 2 shows the supported feature set for the wireless point-to-multipoint headend line card.

About Subscriber Unit P2MP Line Cards

Table 3 shows the supported feature set for the wireless point-to-multipoint headend line card.

About Advanced Radio Signal Analysis

With CiscoView Wireless, you can configure and monitor radio signal parameters in various ways. You can change the following signal attributes:

Common to both headends and subscriber units:

• Signal to interference noise ratio (SINR) for the main and diversity antennas

• Timing Offset

• Received power at the main and diversity antennas

• Channel delay spread at the main and diversity antennas

• Specific to headends only

• Ambient noise

Specific to subscriber units only

• Received power delta at the main and diversity antennas

• Total transmit power

CiscoView Wireless provides the following classes of features to configure and monitor radio signal parameters:

• Histograms

• RF Thresholds

• Timelines

• Snapshots

About Real-Time Histograms

A Histogram represents:

• A technique of capturing, processing, and storing radio signal information in an easy to interpret format

• A graphical representation of the captured data

With CiscoView Wireless, you can create histogram specifications on the managed device. Once the specification is created, the managed device captures the signal information. Then, you can set up the histogram to capture data for a long period of time for a single upstream or for one subscriber unit that is registered with the headend. CiscoView Wireless can then graph the collected data in a periodic manner.

.

Creating a Histogram

With CiscoView Wireless, you can retrieve the captured histogram data (from the managed device) at regular intervals and store them in a database at the server. You can retrieve and view the stored data at a later date

Step 2   Select the Persistent option in the histogram specification. The Histogram specification appears in the Histogram History. [Chassis>Histogram History>This device/All devices].

For each entry in the Histogram History Table, there is a data file in binary format on the server at the location <CD One install directory>/CSCOpx/www/classpath/devpkg_P2MP where the histogram values are updated as specified by update rate parameter.

Step 3   To stop the collection of histograms permanently, click Stop Collection.

Step 4   To convert the data in the binary file to ASCII format, select the histogram specification from the histogram history table, and click Bin to ASCII.

Step 5   To graph the saved data, select a specification from the Histogram History Table and click Graph.

About RF Thresholds

With CiscoView Wireless, you can establish thresholds on radio signal parameters. A threshold is defined as a transition relative to a specified value. The different types of transitions are:

• UpChange

• DownChange

• HighThreshold

• LowThreshold

• UpLimit

• LowLimit

When a threshold is crossed, the managed device generates a trap. You can associate a threshold with a timeline, and when the threshold is crossed, the timeline is captured.

About Timelines

Timelines represent:

• A technique of capturing and storing a limited set of sampled raw radio signal information.

• A graphical representation of the captured data.

You can create timeline specifications on the managed device. Once the specification is created, the managed device captures the signal information. Once captured, the data must be cleared by another clear request before you can initiate another capture. You can capture the data under two conditions:

• If an RF threshold is not associated with the timeline specification, then the data is captured as soon as the create request is sent to the managed device.

• If an RF threshold is associated with the timeline specification, then the data is captured when the threshold is crossed.

You can create timeline specifications on the managed device for the radio signal attributes and graph the data captured by a timeline specification.

About Snapshots

Snapshots represent:

• A technique of capturing and storing radio signal data that has undergone various levels of signal processing. The critical difference between a timeline and a snapshot is that a snapshot can be set up to monitor up to four simultaneous attributes.

• A graphical representation of the captured data.

You can create snapshot specifications on the managed device. Once the specification is created, the managed device captures the signal information. Once the data is captured, it must be cleared by another clear request before you can initiate another capture. You can also graph the data captured by a snapshot specification.
