Calculating an AppNetwork Path analysis
To conduct an AppNetwork Path analysis and view the results in the AppNetwork Path Analysis screen
1. Open the AppNetwork Path Analysis dialog by clicking the
icon in the Home, Search, or Metrics screen or by clicking the
icon in the Topology screen.
The Calculate AppNetwork Path dialog appears.
2. In the dialog, enter the IP address of a source device and the IP address of a destination device.
If you are calculating an AppNetwork Path from within the Topology screen, select Include Reverse Path if you want to generate both the forward (source to destination) and the reverse (destination to source) paths.
3. Click Calculate.
– AppNetwork Path Analysis must find a Telnet-accessible or SSH-accessible device to use as the starting point in the path. It first attempts to consider the source device as the starting point. If the source device is not accessible, AppNetwork Path Analysis uses known model data to determine the router that is closest to the source. If both techniques fail to find an accessible starting point, the path determination process fails, in which case you can supply the Default Router’s address at
step 1.
The same process applies for generating a reverse path, in which case the destination is considered to be the source.
– AppNetwork Path analysis begins. It may take several minutes to generate the requested path(s), but each path is displayed progressively on the Application Path tab as it is analyzed.
An X in the path diagram means that the destination is unreachable from the device that is immediately before the X.
4. A cloud with a question mark or a gray box that is labeled Unknown in the path indicates that there is not enough information about this part of the path, typically because the device is not accessible or is outside the administrative boundaries of the organization.
