Local destinations
A local mirroring traffic destination is a port on the same switch as the source of the traffic being mirrored.
Remote destinations
A remote mirroring traffic destination is an switch configured to operate as the exit switch for mirrored traffic
sessions originating on other switches.
CAUTION: After you configure a mirroring session with traffic-selection criteria and a destination, the
switch immediately starts to mirror traffic to each destination device connected to an exit port. In a
remote mirroring session that uses IPv4 encapsulation, if the intended exit switch is not already
configured as the destination for the session, its performance may be adversely affected by the
stream of mirrored traffic. For this reason, Switch strongly recommends that you configure the exit
switch for a remote mirroring session before configuring the source switch for the same session.
Monitored traffic sources
You can configure mirroring for traffic entering or leaving the switch on:
Ports and static trunks
Provides the flexibility for mirroring on individual ports, groups of ports, static port trunks, or any combination of
these..
Criteria for selecting mirrored traffic
On the monitored sources listed above, you can configure the following criteria to select the traffic you want to
mirror:
• Direction of traffic movement (entering or leaving the switch, or both.)
• Type of IPv4 or IPv6 traffic entering the switch, as defined by a classifier-based service policy.
• Source and/or destination MAC addresses in packet headers.
Mirroring configuration
The table below shows the different types of mirroring that you can configure using the CLI, Menu, and SNMP
interfaces.
