Problem Description
After importing the configuration to the new device, the feedback fails to be obtained across three layers, and the IAG can communicate normally with the 3SW

Process——
- Check the cross-layer configuration and find that IPoid and MACoid are abnormal. Under normal circumstances, the first 9 bits of IPoid and MACoid are consistent, only the last bit is inconsistent. IPoid is one bit larger than MACoid.

solution
Modify the IP oid to 1.3.6.1.2.1.4.22.1.3 to solve the problem
Suggestions and Conclusion
When filling in OID across three layers, the first 9 digits of the OID of IP and MAC should be consistent
Common switch OIDs are as follows (IPOID in front, MACOID in the back)
1.3.6.1.2.1.3.1.1.3/1.3.6.1.2.1.3.1.1.2 (mostly Cisco switches)
1.3.6.1.2.1.4.22.1.3/1.3.6.1.2.1.4.22.1.2 (mostly Huawei and H3C switches)
