Because the remote session has mirroring sources on different switches, you can use the same session
number (1) for both sessions.
Figure 75: Configuring a classifier-based policy on source switch B
Remote mirroring using traffic-direction criteria
In the network shown in the figure below, the administrator connects another traffic analyzer to port B10 (in VLAN
40) on switch C to monitor all traffic entering switch A on port C12. For this mirroring configuration, the
administrator configures a mirroring destination (with a remote exit port of B10) on switch C, and a remote
mirroring session on switch A.
If the mirroring configuration in the proceeding example is enabled, it is necessary to use a different session
number (2) and UDP port number (9400.) (The IP address of the remote exit port [10.10.40.7] connected to traffic
analyzer 2 [exit port B10] can belong to a different VLAN than the destination IP address of the VLAN used to
reach remote switch C [10.20.40.1]).

To configure this remote mirroring session using a directional-based traffic selection on a port interface, the
operator must take the following steps:
