一、 银行网络结构拓扑

二、 骨干网通信故障
1. 故障处理人员
参与人：XX、XX、XX
2. 电信、联通网络通信故障
依据到总行两台cisco 7206路由器日志和实际登陆设备使用show int ATM4/0.1 、ping对端地址、show ip route、show log，查看上述相关设备和线路是否有反复重起、误码率高、异常路由、错误连接等情况即可确定故障。
3. 通信故障恢复
恢复步骤：
1）重启故障新路相连路由器，看是否能够自动恢复
2) 断电重起无法处理故障，停止使用故障设备和线路，预防其影响网络其它部分。
3) 如系线路故障通知各相关方面（逐项对照处理）：
● 如为中国电信线路故障，向31000000 报修，并通知分行办公室相关人员。
● 如为中国联通线路故障，向XXXX 报修，并通知分行办公室相关人员。
4. 到总行路由器故障
查看日志，检验设备故障前异常日志信息；登陆路由器使用show log，show ip int brie , show process cpu his , show ip route , ping对端地址等命令来确定故障。
5. 路由器故障处理
一旦发觉到总行7206路由器故障可按以下步骤来处理：
●联络XX企业，并开启原厂商保修服务备件更换程序。
●因为两台7206路由器是互为备份，一台发生故障不影响实际业务，不调用库房备件和集成商备件更换，等候原厂商备件抵达。
● 对于能够在线插拔接口模块、有standby 引擎和电源，优先使用在线更换方法。在线更换具体操作步骤以下：
a) 用笔记本电脑连接在网络设备Console 上，开启Console 监控和统计；
b) 准备好存档系统配置，备用。如有可能，同时保留目前系统配置；
c) 对故障模块上连接线缆做好标识，小心拔下；
d) 做好安全接地，拔下故障模块；
e) 检验设备和模块状态，确定是否影响整个设备或其它模块正常运行，standby 模块是否正常接管；
f) 做好安全接地，插上更换备件模块；
g) 检验设备和模块状态，确定是否能够正常识别新模块，是否影响其它模块运行；
h) 按原样插上线缆；
i) 检验线缆连接状态正常；
j) 确定备件更换成功。
l 对于机箱、不能在线插拔接口模块、或没有standby 引擎和电源，采取下电更换方法。下电更换具体操作步骤以下：
a) 准备好存档系统配置，备用。如有可能，同时保留目前系统配置；
b) 准备好原先使用系统软件，备用；
c) 故障设备下电；
d) 对需要拔除线缆做好标识，小心拔下。假如机箱或引擎更换，需拔除全部连接线缆；
e) 更换备件；
f) 用笔记本电脑连接在网络设备Console 上，开启Console 监控和统计；
g) 设备上电；
h) 检验系统自检情况，确定无硬件故障；
i) 安装系统软件；
j) 恢复系统配置；
k) 冷开启，确定软硬件正常工作；
l) 按原样插上其它线缆；
m) 检验线缆连接状态正常；
n) 确定备件更换成功。

三、 关键交换机故障应急
1. 一台4506交换机故障应急
查看日志，检验设备故障前异常日志信息；登陆交换机使用show log，show ip int brie , show process cpu his , show ip route , ping对端地址，show vlan brie , show vtp stat , show process mem , show modul , show diag , show ip eigrp nei , show cdp nei等一系列命令来查找、确定故障。
因为两台4506关键交换机完全是热备双机，所以一台发生故障并不影响业务运行。对于配置问题要制订正确更改配置脚本，备份目前配置以后实施更改；对于线路问题要制作新网线，替换故障网线；对于硬件问题要练习XX企业，申请硬件故障维修。
对于能够在线插拔接口模块、有standby 引擎和电源，优先使用在线更换方法。在线更换具体操作步骤以下：
a) 用笔记本电脑连接在网络设备Console 上，开启Console 监控和统计；
b) 准备好存档系统配置，备用。如有可能，同时保留目前系统配置；
c) 对故障模块上连接线缆做好标识，小心拔下；
d) 做好安全接地，拔下故障模块；
e) 检验设备和模块状态，确定是否影响整个设备或其它模块正常运行，standby 模块是否正常接管；
f) 做好安全接地，插上更换备件模块；
g) 检验设备和模块状态，确定是否能够正常识别新模块，是否影响其它模块运行；
h) 按原样插上线缆；
i) 检验线缆连接状态正常；
j) 确定备件更换成功。
l 对于机箱、不能在线插拔接口模块、或没有standby 引擎和电源，采取下电更换方法。下电更换具体操作步骤以下：
a) 准备好存档系统配置，备用。如有可能，同时保留目前系统配置；
b) 准备好原先使用系统软件，备用；
c) 故障设备下电；
d) 对需要拔除线缆做好标识，小心拔下。假如机箱或引擎更换，需拔除全部连接线缆；
e) 更换备件；
f) 用笔记本电脑连接在网络设备Console 上，开启Console 监控和统计；
g) 设备上电；
h) 检验系统自检情况，确定无硬件故障；
i) 安装系统软件；
j) 恢复系统配置；
k) 冷开启，确定软硬件正常工作；
l) 对于交换机要将VTP 设置为Client 模式，首先连接上行线缆，确定VTP 复制正确；
m) 按原样插上其它线缆；
n) 检验线缆连接状态正常；
o) 确定备件更换成功。

2. 当关键交换同时瘫痪在20分钟内确保业务正常运作
现有2台备用cisco3550，在两台关键cisco4506同事瘫痪后，将其作为关键交换来确保业务正常运作，同时保持原有网络拓扑及网络关键安全策略和qos。

网络实施
前期准备
一、8条交叉线（2条做trunk，6条连向楼层交换机）
二、将楼层交换机fa0/47和48口空出来，并做好对应配置
实施步骤
第一步：两台3550上架并加电启用（估计3分钟）
第二步：将连接hp小机光纤接口连到3550上（估计1分钟）
cisco4506主gigabit1/1对应3550主gigabit0/1
cisco4506主gigabit2/2对应3550主gigabit0/2
cisco4506备gigabit1/1对应3550主gigabit0/1
cisco4506备gigabit2/2对应3550主gigabit0/2
第三步：将现成交叉线在3550主备之间互连做ether－channel(估计1分钟)
3550主fa0/47对应3550备fa0/47
3550主fa0/48对应3550备fa0/48
第四步：将连在cisco4506上全部电口全部挪向3550上（估计5分钟）
cisco4506主fa2/3对应3550主fa0/3
cisco4506主fa2/4对应3550主fa0/4
以这类推
cisco4506主fa2/34对应3550主fa0/34
cisco4506备fa2/3对应3550备fa0/3
cisco4506备fa2/4对应3550备fa0/4
以这类推
cisco4506备fa2/34对应3550备fa0/34
第五步：3台楼层交换机和3550之间互连（估计3分钟）
3550主fa0/41对应255.15fa0/47
3550主fa0/43对应255.16fa0/47
3550主fa0/45对应255.17fa0/47
3550备fa0/41对应255.15fa0/48
3550备fa0/43对应255.16fa0/48
3550备fa0/45对应255.17fa0/48
