背景
随着社会的发展,企业信息化建设的推进,全国各大中型企业基本上都有了自己的网络,作为医院的决策者们来说,建立高速的网络,使信息流通更快速,将医院建成信息化的高效的医院,使医院立于不败之林。由于邳州人民医院的网络业务量并不大,主要应用是医院内部的信息传递,除此之外,Http、Ftp、Email便是医院与Internet连接的最大流量了。从技术上讲应该采用标准、开放、可扩充的、能与其它厂商产品配套使用的设计。根据用户的总体需求,结合对应用系统的考虑,我们提出网络系统的设计的原则是:可靠的技术选型、标准的体系结构、1000M骨干网、安全性较高、运行性能可靠以及遵循面向应用,注重实效,急用先上,逐步完善的原则。
- 实用性:根椐应用系统的要求确定整个系统的结构,即从系统功能和信息需求出发,拟建系统的结构必须满足系统的传输能力要求、信息安全要求、人机交互能力要求、信息处理要求等;
- 先进性:以先进、成熟的网络通信技术进行组网,并能确保网络技术和网络产品几年内不落后;
- 可靠性:系统必须可靠运行;
- 开放性:选择的产品应具有好的互操作性和可移植性,并符合相关的国际标准和工业标准;
- 可扩充性:系统是一个逐步发展的应用环境,在系统结构、产品系统、系统容量与处理能力等方面必须具有升级换代的可能,这种扩充不仅能充分保护原有资源,而且具有较高的性能价格比,使整个网络系统是可扩展的,便于系统升级,改装;
- 可伸缩性原则:网络的建设是一项持续性的系统工程项目,坚持网络建设规模的可伸缩性原则,将使得网络的建设费用降低,避免不必要的浪费,也体现了网络建设的灵活性;
- 安全性:信息系统安全问题的中心任务是保证信息网络的畅通,确保授权实体经过该网络安全地获取信息,并保证该信息的完整和可靠。网络系统的每一个环节都可能造成安全与可靠性问题。
拓扑图如下:

网络配置实施
本院配置
接入二层划分vlan、以及接口配置
将每层的1-21口进行Access的vlan划分 23-24口为上行接口
ACC-L1port-group group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/21
ACC-L1-port-groupport link-type access
ACC-L1-port-groupport default vlan 10
ACC-L1int g0/0/24
ACC-L1-GigabitEthernet0/0/24port link-type trunk
ACC-L1-GigabitEthernet0/0/24port trunk allow-pass vlan all
ACC-L1int g0/0/23
ACC-L1-GigabitEthernet0/0/23port link-type trunk
ACC-L1-GigabitEthernet0/0/23port trunk allow-pass vlan all
其他设备相同配置即可
三层SIV接口配置及vrrp配置
interface Vlanif10
ip address 192.168.10.1 255.255.255.0
vrrp vrid 10 virtual-ip 192.168.10.254
vrrp vrid 10 priority 120
interface Vlanif10
ip address 192.168.10.2 255.255.255.0
vrrp vrid 10 virtual-ip 192.168.10.254
配置MSTP
stp region-configuration //进入MSTP模式
region-name huawei //配置域名为huawei
instance 1 vlan 10 //将vlan10 加入实例1中
instance 2 vlan 20 //将vlan20加入实例2中
active region-configuration //激活配置
stp instance 1 root primary //指定本交换机为主根桥
stp instance 2 root sec //指定本交换机为次根桥
其他部分的mstp 与vrrp配置相同
链路聚合配置
在两台汇聚交换机间设置链路聚合,关键代码如下:
interface eth-trunk 0 //创建ID为0的Eth-Trunk接口
trunkport GigabitEthernet 0/0/23 to 0/0/24 将 23 24号口加入到聚合组中
(对端配置完全相同)
路由协议OSPF配置
