摘　　要：VLAN技术在交换式以太网和无线局域网组网中得到了广泛应用。在VLAN配置中,接口VLAN设置是重要内容之一。通过多个案例分析了PVID在VLAN配置中的重要作用和影响,并基于eNSP进行了模拟实验验证。分析得出不同VLAN间实现2层互通的关键在于PVID的设置。在CAPWAP组建无线局域网、智能变电站VLAN应用等场景中,利用了trunk链路类型上PVID特性,实现了特殊的接入功能和不同VLAN间的二层数据交换。融入计算机网络课程实验教学中将有助于学生更好地理解和掌握VLAN技术。VLAN is widely used in switching Ethernet and WLAN networks.In a VLAN configuration case,PVID is important.This paper analyzes the important role and influence of PVID in VLAN configuration through several cases,and conducts simulation experiment verification based on eNSP.It is concluded that the key to achieve two-layer interworking between different VLANs is the setting of PVID,which is also of high application value in network engineering.In the scenarios of setting up WLAN based on CAPWAP and applying VLAN in the intelligent substations,PVID feature of trunk link is used to realize special access function and two-layer data exchange between different VLANs.These contents will help students to better understand and master VLAN technology in the experimental teaching of computer network course.
