假如，6509上面增加新的vlan 比如：增加 vlan 20,则在4908g上需要增加的配置的命令是

在每个千兆口上和快速通道口上划分一个新的子端口，

interface GigabitEthernet1.20

encapsulation dot1Q 20

bridge-group 20

每个端口都参照这样配置。

在router（config）#状态下，加入以下命令：

bridge 20 protocol ieee

按照这种方式就可以增加vlan

cisco 4908g-L3 三层交换机，每个端口均支持三层交换！第三层交换12 Mpps为布线室和数据中心提供高性能、中等密度的、10/100/1000M以太网模块交换平台。
