1、服务器组双链路 上联核心,调高数据可靠性
2、配置vlan,减小广播域范围
3、所有网关都设在核心上,部分ip需自动获取
4、业务端口,配置边缘端口,减小频繁up down对网络的影响
5、配置相关路由,使的用户可以访问外网及新校区
6、广域网出口做主备,线路正常走联通
7、所有设备可以被Telnet ,管理网段255.x,vlan999
8、vlan30 用户不能访问200.4
1、起网桥聚合
2、聚合口为trunk

核心交换机和接入交换机以及路由器 , 要可被Telnet ,就必须有地址(虚接口),
故要设置管理vlan999.并给他一个255.x的地址
使得 所有pc都可以访问各交换机和路由器
[sw1-luser-manage-abc]int vlan 999
[sw1-Vlan-interface999]ip address 192.168.255.1 24
int vlan 999
ip add 192.168.255.x 24
[sw14]ip route-static 0.0.0.0 0 192.168.255.1;用于管理流量的回包
总结以下,除了核心交换机,都应该这么设置
[sw-汇聚]vlan 999
[sw-汇聚-vlan999]int vlan 999
[sw-汇聚-Vlan-interface999]ip a 192.168.255.2 24
