7 Introduction This section provides an introduction to the routing applications used in SPECTRUM. The following sections provide a description of common routing applications used by Aprisma-developed and third-party devices. The application views allow you to view information on those routing applications supported by the device. The major applications are described initially in each section, followed by a description of the minor applications and subviews. Many views are accessed from the application icon subviews menu, while other views are accessed from view buttons, or by double-clicking entries within the application view tables. The application view fields may differ slightly between devices, depending upon the the supported MIBs. Overview The routing applications that are covered in this document are: Generic Routing (Page 8) Repeater (Page 11) AppleTalk (Page 14) DECnet (Page 31) OSPF (Page 46) OSPF2 (Page 61) If the routing application in which you are interested is not listed in this document, check the management module documentation for the device you are monitoring. Some routing applications are specific to that device. Routing Applications Page 7

8 Generic Routing Generic Routing Overview This section describes the Generic Routing Application. The Generic Router application (GenRtrApp) provides access to : \Generic Routing Protocol Comparison View (Page 9) Generic Routing Detailed Protocol Comparison View (Page 10) The statistics include the total and percentage of successful frames. Each slice of pie corresponds to the frame statistic percentage for active protocols. A total number of frames for all protocols is displayed under each pie chart. Routing Applications Page 8

9 Generic Routing Overview Generic Routing Protocol Comparison View Access: From the Icon Subviews menu for the GenRtrApp Application icon, select Protocol Comparison. The Generic Routing Protocol Comparison view s three pie charts display frame statistics for supported routing protocols. Frames Forwarded Provides this protocol s frames and percentage of the total number of frames or packets forwarded. Frames Delivered Provides this protocol s frames and percentage of the total number of frames or packets delivered. Frames Transmitted Provides this protocol s frames and percentage of the total number of frames or packets transmitted. Routing Applications Page 9

10 Generic Routing Overview Generic Routing Detailed Protocol Comparison View Access: Click the More button at the bottom of the Generic Routing Protocol Comparison view. The Generic Routing Detail Protocol Comparison view provides Errors and Discards pie charts. Errors Provides this protocol s packet errors and percentage of the total number of packet errors sent. Discards Provides this protocol s packets discarded and percentage of the total number of packet discards. For more information on the Total, Delta, Accum, and Clear buttons that appear with each pie chart, refer to the SPECTRUM Views documentation. Routing Applications Page 10
