Multiple RTP connections can exist over the same HPR route. For example, in Figure 1, multiple RTP connections can exist between HOSTA and HOSTD through HOSTB. Furthermore, it is possible that more than one of these connections are for sessions requiring the same Class of Service. In this case, to determine which connection a session is traversing, use the DISPLAY SESSIONS command at one of the RTP endpoints. First use DISPLAY SESSIONS to find the session identifier (SID) for the session in question. Then issue DISPLAY SESSIONS and specify the SID on the SID operand. The resulting display shows the RTP PU (CNRnnnnn, unless the DYNHPPFX start option has been used to change the default prefix) as the ALSNAME, if the session is over an HPR route.
