Diagnostic Manager

 

Understanding the Diagnostic Manager

The Diagnostic Manager provides an interface to keep track of ping and traceroute operations performed on the live network. To open Diagnostic Manager, select Performance > Diagnostics > Diagnostic Manager. Figure 1 shows the Diagnostic Manager window populated with the results of a ping test.

Figure 1: Diagnostic Manager Window
Diagnostic Manager Window

The ping and traceroute features provide the following options:

Ping > Device From DevicePing from one device to another device. The Advanced option provides a selection of ping commands for the device.
Ping > Multiple Devices From DevicePing from one device to multiple devices.
Ping > Devices from ServerPing from the IP/MPLSView server to multiple devices.
Ping > Devices to Device/ServerPing from multiple devices to a device or to the IP/MPLSView server. Note that even if the server can ping a device by its loopback address, this does not guarantee that the device can also ping the server. It is possible that the source interface that the device uses to ping the server is unreachable to the server, so that the ping response never returns to the device.
Ping > Continuous PingPing at regular intervals between two devices and display the result graphically. The Advanced option provides a selection of ping commands available for the device.
Traceroute > Device From DeviceTraceroute between two devices and display the path on the map (right-click menu option). The Advanced option provides a selection of traceroute commands available for the device.
Traceroute > Multiple Devices From DeviceTraceroute from one device to multiple devices.

The grouped pings feature provides the following options:

Ping/Traceroute within Device GroupPerform a ping between each pair of routers in the group.
Ping/Traceroute between Device GroupsPerform a ping from routers in the first group to routers in the second group.
Ping/Traceroute from Device Group to Multiple DevicesPing from routers in the first group to selected routers.
Ping within Devices of VPNFor a given Layer 3 VPN, ping from PE to CE, CE to PE, or PE to CE loopback. This VPN group must be predefined by selecting Grouping > Customized VPN Diagnostics.
Ping/Traceroute by Customized Advanced GroupPerform a ping between each designated pair of source router/interface and destination router/interface. This option is useful if you need to specify a particular source interface to use for the ping. This group must be predefined by selecting Grouping > Customized Advanced Group.

For each ping or traceroute operation performed from the Ping and Traceroute buttons or from the Tools > Diagnostics menus, an entry is added to the Diagnostic Results Panel window, describing the operation and the time it was performed. Click on a row to display the results in the Output Panel window.

  • For each entry, a green circle indicates a successful operation, a timer glass indicates an operation in progress, and a red circle indicates a failed operation.

  • Right-clicking a row in the Diagnostic Results Panel window, as shown in Figure 1, provides options to rerun a ping or traceroute, show the path for a traceroute, stop a continuous ping and turn off the chart view for continuous ping, or delete an entry.

  • The buttons in the lower left of the window allow the user to save a single entry or all entries to a text file on the client machine, and to view details of an item in a separate window.

For diagnostic configuration settings, see “Configuration Revision Manager.”

Pinging from Device to Device

To measure connectivity, round-trip time (RTT), delay, and packet loss, you can use a ping operation from one device to another device, or from one device to multiple devices. The round-trip time (RTT) is the time from the moment the ping packet is sent to the time a reply is received. After a number of pings, the minimum, maximum, and average round-trip time, in milliseconds, is collected, as well as the standard deviation and percentage packet loss.

  1. Select Performance > Diagnostics > Diagnostic Manager.
  2. In the Diagnostic Manager window, click Ping > Device from Device.

    The Ping dialog box is displayed.

  3. Select the source device and destination device from the lists.
  4. (Optional) Select any of the following options:
    Use Management IPPing the destination device’s management IP address, where the management IP address is the IP address defined in the router profile that is used by the IP/MPLS server to collect information from the router. This option is the default.
    Use Loopback IPPing the destination device’s loopback IP address.
    Choose Source InterfaceChoose the source interface from a list.
    Choose Destination IPType a specific IP address for the destination device.
  5. (Optional) Click Options to change the diagnostic timeout from the default of 30 seconds.
  6. Click Run to execute the ping request.

    The ping results are displayed in the Output Panel, as shown in Figure 1.

Pinging Multiple Devices from a Device

To perform a ping test from a single device to multiple devices:

  1. Select Performance > Diagnostics > Diagnostic Manager.
  2. In the Diagnostic Manager window, click Ping > Multiple Devices from Device.

    The Ping dialog box Figure 2 is displayed, as shown in Figure 2.

  3. In the From list, select the source device to ping from.
  4. (Optional) From the Filter destination devices by type list, select All Devices or a specific vendor.
  5. Select the devices to ping from the source device, or select Device to ping all devices.
  6. (Optional) Select any of the following options:
    Use Management IPPing the destination device’s management IP address, where the management IP address is the IP address defined in the router profile that is used by the IP/MPLS server to collect information from the router. This option is the default.
    Use Loopback IPPing the destination device’s loopback IP address.
  7. (Optional) Click Options to change the diagnostic timeout from the default of 30 seconds.
  8. Click Run to execute the ping request.

    The ping results are displayed in the Output Panel, as shown in Figure 1.

Pinging Multiple Devices from a Server

To ping multiple devices from the server:

  1. Select Performance > Diagnostics > Diagnostic Manager.
  2. In the Diagnostic Manager window, click Ping > Multiple Devices from Server.

    The Ping dialog box is displayed.

  3. (Optional) From the list, select All Devices or a specific vendor.
  4. Select the devices to ping from the server or select Device to ping all devices.
  5. (Optional) Select any of the following options:
    Use Management IPPing the destination device’s management IP address, where the management IP address is the IP address defined in the router profile that is used by the IP/MPLS server to collect information from the router. This option is the default.
    Use Loopback IPPing the destination device’s loopback IP address.
  6. (Optional) Click Options to change the diagnostic timeout from the default of 30 seconds.
  7. Click Run to execute the ping request.

    The ping results are displayed in a table in the Output Panel and indicate the round-trip time and packet loss information for each device being pinged. Table 1 shows the items and descriptions.

Pinging and Traceroute for Device Groups

To perform a ping or traceroute within a group, between groups, or between a group and selected routers, a group of devices must first be created.

To create a group and then perform a ping or traceroute for that group:

  1. Select Performance > Diagnostics > Diagnostic Manager.
  2. In the Diagnostic Manager window, click Grouping > Device Group.

    The Diagnostics Device Group window is displayed, as shown in Figure 4.

  4. Select from the list of available devices in the left and click the arrow to move them into the group. Then click OK.

Pinging and Traceroute for a Customized Advanced Group

To use ping or traceroute and specify greater detail for the device groups, including the specific interface to use, create a customized advanced group:

  1. Select Performance > Diagnostics > Diagnostic Manager.
  2. In the Diagnostic Manager window, click Grouping > Customized Advanced Group.
  3. The Diagnostics Custom Group window is displayed, as shown in Figure 5.
    Figure 5: Diagnostics Custom Group
