Classifier-based mirroring restrictions

The following restrictions apply to mirroring policies configured with the classifier-based model:

• 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.

• 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.
