#### Displaying VNIP Database Information

  The Virtual Network Interactive Protocol (VNIP) management tool, available on the FRAP and T-FRAP, collects topographical and round-trip transit delay information on detected Frame Relay Permanent Virtual Circuits (PVC) passing through their interface ports on a DLCI-by-DLCI basis. VNIP topology and transit delay information, although viewed from the same window, provide very different types of information. VNIP Topology information describes the virtual path of each DLCI in terms of"hops" or segments between circuit nodes. The topology of each hop includes;the local virtual circuit DLCI identifier, the discovered peer device IP address, and the remote virtual circuit DLCI (how the virtual circuit is identified by the peer device). The VNIP Transit Delay feature is responsible for compiling round-trip transit delay statistics on the virtual circuits found in the VNIP Topology database. The VNIP Table window provides the user with VNIP Topology and Transit Delay information.
  To open the VNIP Table window:
  1 Position the mouse arrow over the Unit Detail window's graphical representation of the COMM port, and click the right mouse button.
  2 Select VNIP Table... from the list of pull-down menu options and click the left mouse button.
  The fields and buttons contained within the VNIP Table window are described in the following paragraphs.
  Port - Identifies the interface port(e.g. network,DTE) off of which the remote peer device was discovered.
  Hops - Identifies the number of hops that the discovered peer device is away from the local node.
  Notes:Virtual circuits having multiple discovered peer devices associated with the same local DLCI will have each peer device described in supplemental topology line entries.
  Switches located within the "cloud" are not considered node devices and will not be included in the topology. Only when the virtual circuit encounters a node device whose VNIP protocol is activated does the hop count increase.
  Remote Address - Identifies the Internet Protocol (IP) address of the discovered peer device.
  DLCI(remote node) - Identifies the DLCI of the discovered peer device.
  Min Delay - This column identifies the lowest (minimum) transit delay between the local node and the remote peer device.
  Max Delay - This column identifies the greatest (maximum) transit delay between the local node and the remote peer device.
  Avg Delay - This column identifies the average transit delay between the local node and the remote peer device.
  Update - Clicking this button will update (refresh) the information contained in the VNIP Table.
  Time Box - Located to the right of the Update button. The time displayed in this box indicates when the VNIP Table window was opened or the time the table was last Updated.
  Done - Clicking this button will close the VNIP Table window.
