• The following restrictions apply to ports configured to be source ports:
• Port monitoring Source Ports must be simple ports, and not port-channels.
• The port cannot be already configured as a destination port.
• All the frames are transmitted as either always tagged or always untagged.
General Restrictions:
• Ports cannot be configured as a group using the interface range ethernet command.
NOTE: The Port Mirroring target must be a member of the Ingress VLAN of all Mirroring source ports.
Therefore, Multicast and Broadcast frames in these VLANs are seen more than once. (Actually N+,
where N equals four).
When both transmit (Tx) and receive (Rx) directions of more than one port are monitored, the
capacity may exceed the bandwidth of the target port. In this case, the division of the monitored
packets may not be equal. The user is advised to use caution in assigning port monitoring.
