Abstract: This invention discloses a type of 1,8-bis(Schiff base)-p-menthane derivatives as well as their preparation method and applications. The reaction of 1,8-diamino-p-menthane with a substituted benzaldehyde was carried out in a polar organic solvent at 0° C.-75° C. for 1-48 h. After the completion of the reaction, part of the solvent was distilled off to perform recrystallization to get a 1,8-bis(Schiff base)-p-menthane derivative, whose pre-emergence herbicidal activity against ryegrass was determined by using the Petri dish seed germination method. The 1,8-bis(Schiff base)-p-menthane derivatives, obtained with this method in high yield and mild reaction conditions, have a good inhibitory effect on the growth of annual ryegrass, and low toxicity.

Abstract: A network device stores a Virtual Extensible Local Area Network (VxLAN) Tunnel Endpoint (VTEP) membership information that associates VxLANs each with a corresponding set of VTEPs authorized to originate VxLAN packets on that VxLAN. The network device receives from a communication network a VxLAN packet that identifies a VxLAN and an originating VTEP. The VTEP compares the originating VTEP to the set of VTEPs associated with the VxLAN in the VTEP membership information that matches the identified VxLAN. If the comparison indicates that the originating VTEP is not included in the set of VTEPs authorized to originate VxLAN packets, the VTEP discards the received VxLAN packet. Otherwise the VTEP further processes the VxLAN packet.
