• A mirroring policy is supported only on
inbound
IPv4 or IPv6 traffic.
• A mirroring policy is not supported on a meshed port interface. (Classifier-based policies are supported only on
a port, VLAN, or trunk interface.)
• Only one classifier-based mirroring policy is supported on a port or VLAN interface. You can, however, apply a
classifier-based policy of a different type, such as QoS.
• You can enter multiple
class action mirror
statements in a policy.
◦ You can configure only one mirroring session (destination) for each class.
◦ You can configure the same mirroring session for different classes.
• If a mirroring session is configured with a classifier-based mirroring policy on a port or VLAN interface, no
other traffic-selection criteria (MAC-based or all inbound and/or outbound traffic) can be added to the session.
Figure 67: Mirroring configuration in which only a mirroring policy is supported
• If a mirroring session is already configured with one or more traffic-selection criteria (MAC-based or all inbound
and/or outbound traffic), the session does not support the addition of a classifier-based policy.

About applying multiple mirroring sessions to an interface
You can apply a mirroring policy to an interface that is already configured with another traffic-selection method
(MAC-based or all inbound and/or outbound traffic) for a different mirroring session.
The classifier-based policy provides a finer level of granularity that allows you to zoom in on a subset of port or
VLAN traffic and select it for local or remote mirroring.
