Viewing Statistics

The Statistics dialog box enables you to view statistics for major events of the MVP120 operation. This dialog box is accessed by clicking Statistics on the MVP120 Main menu.

The Voice Channel statistics shows the attempted and completed calls, call duration, average call length, bytes/packets sent and received. These statistics can be a helpful troubleshooting tool.

IP Statistics

IP is a connection-less network protocol residing in the network layer of a conventional OSI layered model (for more information on this model, refer to Appendix A). Depending on what is going on at the application layer, IP will typically use one of two transport layer protocols. User Datagram Protocol (UDP), a connection-less transport layer protocol used with TFTP or SNMP; and Transport Control Protocol (TCP), a connection-oriented transport layer protocol used with FTP, Telnet, and SNMP.

UDP makes use of the port concept and has no measures for flow control, reliability, or error recovery. It is used when the full services of TCP are not required, and the reliability measures must be assumed by another layer.

TCP works well in environments where the reliability measures are not assumed by other layers. It is connection-oriented and has a full range of services.

These statistics are informational, and their use as a troubleshooting tool will be contingent on the applications running in the upper layers. For example, if you were having problems
