Using Topology Views

There are two types of topology views available in Cisco netManager: the Service Level View and the Physical Connectivity View.

Note The Service Level View is available only if you have purchased a license that monitors Unified Communication devices.

Using the Service Level View

Note The Service Level View is available only if you have purchased a license that monitors Unified Communication devices.

Cisco netManager's Service Level View displays a logical topology view of your Cisco Unified Communications network. You can access the Service Level View from your Home Page View or from GO > Views > Service Level.

The Service Level View shows all the Cisco Unified Communications Manager clusters: all instances of Cisco Unified Communications Manager Express, associated gateways and application servers. The Service Level View is designed so that you can set it up and leave it running, providing an ongoing monitoring tool that signals you when something needs attention.

Note When changing a Cisco Unified Communications application's registration from one Cisco Unified Communications Manager cluster to another, you must remove the registration of the application to the old Cisco Unified Communications Manager cluster in both the application and the old Cisco Unified Communications Manager cluster. If you do not do this, registration of the application with the old Cisco Unified Communications Manager cluster will continue to appear in the Down state in the Service Level View.

You can use the Service Level View to:

•Display a logical topology view of your Unified Communications deployment. See Starting the Service Level View.

•View recent events releated to the IP telephony devices associated with Cisco Unified Communications Manager clusters. This allows you to see a visual representation of your Unified Communications deployment while, at the same time, actively monitoring all devices in your network.

•Run other Cisco netManager tools. For more information, see "Launching Network Tools" section.

•Launch administration pages for devices. For more information, see "Launching Administration Pages for Devices" section.

Starting the Service Level View

To start the Service Level View, select GO > Views > Service Level View.

Phones Pane

In the phones pane, you can search for a specific phone endpoint and view the phones report. For more information, see the following topics:

•Using the Search Tool to Locate a Phone

•Launching a Phone Report from the Service Level View

Using the Search Tool to Locate a Phone

When you click a phone from the phone endpoint search results, the map display pane displays a drilled-down view, with the phone highlighted. The phone will have a logical link to the Cisco Unified Communications Manager to which it is registered.

Step 1 In the search field located in the phones pane, select whether you want to search by extension number, IP address, or MAC address.

Step 2 Enter the appropriate number for the phone.

Step 3 Click Go.

Launching a Phone Report from the Service Level View

Step 1 Do one of the following:

•Click Click to View All Phones in the phones pane. The phones report for all phones opens in another window.

•Right-click a phone or a Cisco Unified Communications Manager icon in the map display pane, then select Associated Phones. The phones report for the selected phone opens in another window.

Map Display Pane

The map display pane shows the registration status of IP telephony devices. This information is displayed in a map-based view. You can drill down to devices in the display pane by clicking the cluster cloud. To get back to the cluster cloud view, click the Unified Communications Devices link (located just at the bottom of the View Status Bar Area).

Drilling down on these clouds shows the individual devices with relevant information. This gives you a quick snapshot of the overall health of your Unified Communications network.You can easily locate devices and links that may cause problems and view the underlying infrastructure of your Unified Communications network.You can view link or port status and device information by moving your cursor over any link or device icon. For more information on device icons and links, see Topology Views Legend. In general, the colors of the icons represent the following:

•Green—Devices that are managed by Cisco netManager.

•Gray—Devices that are not managed by Cisco netManager.

•Red—Devices that are down.

Note If a device icon is not connected to anything, it means that Cisco netManager is unable to get its connectivity details because CDP protocols are not enabled on the device.

For example, in Figure 4-2, the following Service Level View information is displayed:

•The large circle represents the logical grouping of Cisco Unified Communications Managers in this cluster.

•The H323 icon shows that the voice gateways are registered to the cluster using H323 protocol.

•Three of the voice gateways are not monitored by Cisco netManager. Two of the managed voice gateways and the Cisco Unified Communications Manager Express have issued critical events.

•The MGCP icon shows that the voice gateway connected to the Cisco Unified Communications Manager is using MGCP protocol. Both devices have issued critical events.

•The APP Server icon shows that other IP telephony applications are connected to a Cisco Unified Communications Manager. In this example, a Cisco Unity device (voicemail server) is connected to the Cisco Unified Communications Manager.

•A tooltip displays useful information about a device or link. A tooltip appears after you move your cursor over a link or device. In this example, it displays the Cisco Unity ports' registration status with the Cisco Unified Communications Manager.

•Gray device icons represent devices that are not managed by Cisco netManager. If you want to monitor all IP telephony devices within the cluster, you can add the device. For more information on adding devices, see Adding a New Device, page 2-4.

•Blue or green device icons represent devices that are managed by Cisco netManager.

•Red icons represent devices that are down.

•Devices that have alerts will have critical (red), warning (yellow), or informational (blue) icons in the upper-right corner of the device icon. See the Summary Pane to view actual representations of icons.

Note If a device is not part of a cluster, it will not be shown.

Note To enlarge or reduce the size of the map display, use the size slider at the top of the pane. The size slider can be used in either the Service Level View or Physical Connectivity View.

Using the Physical Connectivity View

The Physical Connectivity View gives you a visual representation of all physical devices and connections in your network. This view gives a quick snapshot of your entire network, including its overall health. From the Physical Connectivity View, you can easily see which devices and connections are down.

Note•Once a device is added, it may take some time for it to be discovered and appear in the Physical Connectivity View.

•To enable you to view lightweight access points, CDP must be enabled and all connected switches added to the Cisco netManager database.

You can view link or port status and device information by moving your cursor over any link or device icon. For more information on device icons and links, see Topology Views Legend. In general, the color of the icons represent the following:

•Green—Devices that are managed by Cisco netManager.

•Gray—Devices that are not managed by Cisco netManager.

•Red—Devices that are down.

•Devices that have alerts will have critical (red), warning (yellow), or informational (blue) icons in the upper-right corner of the device icon. See the Summary Pane to view actual representations of icons.

Note If a device icon is not connected to anything, it means that Cisco netManager is unable to get its connectivity details because CDP protocols are not enabled on the device.

From within the Physical Connectivity View, you can also launch several Cisco netManager tools, external applications, and device administration pages. To access these tools and applications, right-click an object in the view; the available options are displayed in a menu box. For more information, see "Launching Network Tools" section.

This tool sends out an Internet Control Message Protocol (ICMP) echo request to the network device identified in the Address/Host name field. The results of this request appear on the right side of the page after the request has been made.

Step 1 Right-click the device you want to connect to.

Step 2 From the menu, select Ping. The following fields appear:

Address/Host name—The target of the ping echo request. Enter the hostname or IP address of the device you want to check.

Timeout—Enter the amount of time (in milliseconds) for the tool to wait for a response from the device. The Ping fails if this time limit is exceeded.

Count—Enter the number of data packets sent by the Ping tool.

Packet size—Enter the size (in bytes) of the packets you want the Ping tool to send. 32 bytes is the default.

Results:

•Result—Success or Failure.

•RTT—Round trip time; the amount of time it takes for the ping request to be returned from the remote device.

•Address—The IP address of the device

Using the DNS Lookup Tool

Lookup is a debugging tool that lets you query your Internet domain name system (DNS) server for information about a domain and its registered hosts. Lookup can show you what happens when an application on your network uses your DNS server to find the address of a remote host.

Step 1 Right-click the device you want to connect to.

Step 2 From the menu, select Lookup. The following fields appear:

Address/Host name—Enter the hostname or IP address of the device you want to trace the route to.

Lookup Type—Select the lookup type from the drop-down list.

A—Look up the host's Internet address from the hostname.

PTR—Look up the hostname from the Internet address.

Using the Trace Route Tool

This tool sends out echo requests to a specific device, then traces the path it takes to get to that IP address or hostname. This is useful in finding out where on your network an interruption occurs.

Step 1 Right-click the device you want to connect to.

Step 2 From the menu, select TraceRoute. The following fields appear:

Address/Host name—Enter the host name or IP address of the device you want to trace the route to.

Timeout—Enter the amount of time (in milliseconds) for the tool to wait on a response from the device. The trace route fails if this time limit is exceeded.

Max hops—Enter the maximum number of hops you want to limit the route to. Usually, 32 hops should be enough to find any device on the Internet.

Result—Success or Failure. This is the general result of each hop in the trace route process.

RTT #1/#2/#3—The tool sends out three ping requests to each hop in the route to the device. These columns show the round-trip time for each of the requests.

Address—The IP address of each device encountered on the path.

Host name—The host name of each device encountered on the path.

Using the Telnet Tool

Step 1 Right-click the device you want to connect to.

Step 2 From the menu, select Telnet. This launches a Telnet session for the device.

Using the MAC Address Tool
