CISCO4908的设置案例

IT知识配置 Cisco

网络技术是从1990年代中期发展起来的新技术，它把互联网上分散的资源融为有机整体，实现资源的全面共享和有机协作，使人们能够透明地使用资源的整体能力并按需获取信息 。资源包括高性能计算机、存储资源、数据资源、信息资源、知识资源、专家资源、大型数据库、网络、传感器等 。当前的互联网只限于信息共享，网络则被认为是互联网发展的第三阶段 。CISCO 4908G配置：

如果，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 。
