This action attribute, when specified, will determine where a snapshot of a packet being mirrored will be taken for mirroring purposes. The packet that was 'received' by the device will be mirrored (i.e., packet modifications that may occur during processing will not appear in the mirrored data) when the direction attribute has the value 'ingress(1)'. The packet that is to be 'transmitted' by the device will be mirrored (i.e., packet modifications that may occur during processing will appear in the mirrored data) when the direction attribute has the value 'egress(2)'. Note that the value of this attribute is only considered if the ntnQosActionExtMirrorFrame attribute is 'true'.
