The \"mirror\" instruction is used\n+; to flag the current packet for mirroring, which means that at TX time, before the current packet\n+; is sent out, it will first be cloned (using either the fast or the slow/deep cloning method) and\n+; the clone packet sent out on the output port specified by the mirror session.\n+;\n+; In this example, the UDP packets with destination port 5000 are mirrored to the output port\n+; specified by the mirror session 0, while the rest of the packets are not mirrored. Therefore, for\n+; every UDP input packet with this specific destination port there will be two output packets (the\n+; current packet and its clone packet), while for every other input packet there will be a single\n+; output packet.\n+ \n+//\n+// Headers\n+//\n+struct ethernet_h {\n+\tbit<48> dst_addr\n+\tbit<48> src_addr\n+\tbit<16> ethertype\n+}\n+\n+struct ipv4_h {\n+\tbit<8> ver_ihl\n+\tbit<8> diffserv\n+\tbit<16> total_len\n+\tbit<16> identification\n+\tbit<16> flags_offset\n+\tbit<8> ttl\n+\tbit<8> protocol\n+\tbit<16> hdr_checksum\n+\tbit<32> src_addr\n+\tbit<32> dst_addr\n+}\n+\n+struct udp_h {\n+\tbit<16> src_port\n+\tbit<16> dst_port\n+\tbit<16> length\n+\tbit<16> checksum\n+}\n+\n+header ethernet instanceof ethernet_h\n+header ipv4 instanceof ipv4_h\n+header udp instanceof udp_h\n+\n+//\n+// Meta-data.\n+//\n+struct metadata_t {\n+\tbit<32> port\n+\tbit<32> mirror_slot\n+\tbit<32> mirror_session\n+}\n+\n+metadata instanceof metadata_t\n+\n+//\n+// Pipeline.\n+//\n+apply {\n+\trx m.port\n+\textract h.ethernet\n+\textract h.ipv4\n+\textract h.udp\n+\n+\t//\n+\t// Mark for mirroring all packets with UDP destination port of 5000.\n+\t//\n+\tMIRROR_UDP_DST_PORT_5000 : jmpneq EMIT h.udp.dst_port 5000\n+\tmov m.mirror_slot 0\n+\tmov m.mirror_session 0\n+\tmirror m.mirror_slot m.mirror_session\n+\n+\tEMIT : emit h.ethernet\n+\temit h.ipv4\n+\temit h.udp\n+\ttx m.port\n+}\n", "prefixes": [ "V4", "4/6" ] }
