Users Guide

The maximum number of source ports that can be supported in a session is 128.
The maximum number of destination ports that can be supported is 4 per port pipe.
In the following examples, ports 1/13, 1/14, 1/15, and 1/16 all belong to the same port-pipe. They are pointing to four different destinations
(1/1, 1/2, 1/3, and 1/37). Now it is not possible for another source port from the same port-pipe (for example, 1/17) to point to another
new destination (for example, 1/4). If you attempt to configure another destination (to create 5 MG port), this message displays: %
Error will be thrown in case of RPM and ERPM features.

used.
