AI Technical Summary
Technical Problem
Existing IFIT detection methods only support node-level detection and cannot support tunnel detection, resulting in inaccurate latency detection.
Method used
By issuing tunnel entries and IFIT entries to the NP and setting the initial state to disable latency detection, the accuracy of latency detection is ensured only when traffic is received at the target tunnel interface.
Benefits of technology
It achieves accurate latency detection of tunnels, avoids the problem of inaccurate latency detection caused by multiple link hashes, and dynamically responds to tunnel traffic path switching.

Abstract
The present specification provides an IFIT method and network device for a tunnel, the method comprising: issuing a tunnel table entry to a NP, and issuing an IFIT table entry for each tunnel interface, and setting the initial state of the IFIT table entry as not enabling delay detection; when detecting that a target tunnel interface in each tunnel interface receives traffic, sending interface information of the target tunnel interface to the NP, so that the NP enables the delay detection function of the target tunnel interface according to the interface information. Through the method, IFIT detection can be performed on a virtual tunnel.
