Cisco交换机与华为交换机互连出现VTP问题
Huawei-----------------(trunk)---------------cisco连接后CISCO上出现了非常多的如下信息：
Switch#
29w0d: %DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port Fa0/48 because of VTP domain mismatch.
29w0d: %DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port Fa0/48 because of VTP domain mismatch.
29w0d: %DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port Fa0/48 because of VTP domain mismatch.
29w0d: %DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port Fa0/48 because of VTP domain mismatch.
经检查是VTP的问题，华为上没有VTP协议，但支持GVRP协议，两者不兼容，因此关闭DTP，可解决：
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#interface 接口名称
Switch(config-if)#switchport nonegotiate
Switch(config-if)#
