There is no limitation on the number of mirroring sources and more than a single source can be
mapped to a single analyzer destination.
5.10.1 Mirroring Sessions
Port mirroring is performed by configuring mirroring sessions. A session is an association of a
mirror port (or more) and an analyzer port.

A mirroring session is a monitoring configuration mode that has the following parameters:
Table 30 - Mirroring Parameters
Parameter Description Access
Source interface(s) List of source interfaces to be mirrored. RW
Destination interface A single analyzer port through which all mirrored traffic egress. RW
Header format The format and encapsulation of the mirrored traf
fic when sent to analyzer. RW
Truncation Enabling truncation segments each mirrored packet to
64 bytes. RW
Congestion control Controls the behavior of the source port when destination port is congested. RW
Admin state Administrative state of the monitoring session. RW
5.10.1.1 Source Interface
The source interface (mirror port) refers to the
interface from which the traffic is monitored. Port
mirroring does not affect the switching of the original traffic. The traffic is simply duplicated and
sent to the analyzer port. Traffic in any direction (either ingress, egress or both) can be mirrored.
