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.
