Packet Mirroring Method, Apparatus, and System

A method, comprising:

• receiving a service packet;
• determining a mirroring index based on a mapping relationship and feature information in the service packet, wherein the mapping relationship indicates that the mirroring index corresponds to the feature information;
• obtaining an Internet Protocol version 6 (IPv6) packet based on the service packet and the mirroring index, wherein the IPV6 packet comprises the service packet and a packet header, and wherein the packet header comprises the mirroring index;
• and
• forwarding the IPV6 packet.

An apparatus comprising:

• a memory configured to store instructions;
• a packet observing port;
• and
• one or more processors coupled to the memory and configured to execute the instructions to cause the apparatus to:
• receive an Internet Protocol version 6 (IPv6) packet comprising a service packet and a packet header, wherein the packet header comprises a first mirroring index corresponding to feature information in the service packet;
• determine packet observing port information based on the first mirroring index and a first-mapping relationship, wherein the packet observing port information indicates the packet observing port;
• and
• mirror the IPV6 packet to the packet observing port.
