Port Monitoring Port monitoring is supported on both physical and logical interfaces, such as VLAN and port-channel interfaces. The source port (MD) with monitored traffic and the destination ports (MG) to which an analyzer can be attached must be on the same switch. You can configure up to 128 source ports in a monitoring session. Only one destination port is supported in a monitoring session. The platform supports multiple source-destination statements in a single monitor session. 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 depends on the port mirroring directions as follows: • 4 per port pipe, if the four destination ports mirror in one direction, either rx or tx. • 2 per port pipe, if the two destination ports mirror in bidirection. • 3 per port pipe, if one of the destination port mirrors bidirection and the other two ports mirror in one direction (either rx or tx). 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.
