Abstract:
Embodiments of this application provide a method for obtaining path information and an apparatus, relate to the communications field, and can accurately obtain a forwarding path for detecting a service packet. A service packet is obtained, where the service packet is a target service packet or an updated target service packet, the target service packet is a service packet that matches a flow rule, and the flow rules used to obtain the service packet that matches the flow rule; an ingress interface information field and/or an egress interface information field is/are generated according to a path detection tag on an ingress interface and/or an egress interface through which the service packet passes. The method is used to obtain path information of the service packet.

Claim (Index 16):
The forwarding device according to  claim 11 , wherein:\n when the forwarding device is an intermediate device, the service packet is an updated target service packet, and the program code, when executed, causes the forwarding device to:\n generate a second ingress interface information field and/or a second egress interface information field according to a path detection tag on an ingress interface and/or an egress interface through which the updated target service packet passes, to obtain another updated target service packet, wherein the other updated target service packet comprises connectivity fault management information comprising an Ether type field, a connectivity fault management header field, a first ingress interface information field and/or a first egress interface information field, the second ingress interface information field and/or the second egress interface information field, and an end field, and wherein the connectivity fault management information is located at a tail of an Ethernet packet of the service packet; and \n the forwarding device further comprises:\n a second interface circuit, configured to forward the another updated target service packet.
