VLAN典型配置举例

1、VLAN典型配置举例组网需求Device A 与对端 Device B 使用 Trunk 端口 GigabitEthernet1/0/1 相连; 文档收集自网络，仅用于个人学习该端口的缺省 VLAN ID为100；该端口允许 VLAN2 VLAN6到VLAN50 VLAN100勺报文通过。文档收集自网络，仅用于个人学习组网图图1-4配置基于端口的VLAN组网图配置步骤 配置Device A# 仓U建 VLAN2 VLAN6到 VLAN50 VLAN100 system-viewDeviceA vlan 2DeviceA-vla n2 quitDeviceA vlan 100DeviceA-vl

3、d vlan 100于个人学习# 配置 GigabitEthernet1/0/1是允许VLAN啲报文通过的）禁止VLAN1的报文通过（所有端口缺省情况下都。 文档收集自网络，仅用于个人学习undo port trunk permit vian 1 文档收集自网络,DeviceA-GigabitEthernet1/0/1# 配置 GigabitEthernet1/0/1 过。文档收集自网络，仅用于个人学习仅用于个人学习允许 VLAN2 VLAN6到 VLAN50 VLAN100的报文通DeviceA-GigabitEthernet1/0/1 port trunk permit vlan 2 6

4、to 50 100文档收集自网络，仅用于个人学习Please wait.
