An operator can configure multiple mirror source services, each asking for the same packets. For instance, using two different mirror source services for a filter and SAPs from the same port. A packet is only mirrored once and in such cases the system selects the highest priority mirror. The mirror source priority, from lowest to highest priority for access ports, is defined below:
port mirroring
SAP mirroring
subscriber mirroring
filter mirroring
As an example, when mirroring is enabled on a port for both filter and SAP, packets that matches filter entries rule are mirrored first to the mirror destination for the filter. The rest of the packets that do not match the filter are mirrored to the mirror destination specified for the SAP.
The mirror source priority, from lowest to highest priority for network ports, is defined below:
port mirroring
label mirroring
filter mirroring
