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
根据到总行的两台cisco 7206路由器的日志以及实际登陆设备使用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重复重起、误码率高、异常路由、错误连接等情况即可确认故障。
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) 断电重起无法解决故障的,停止使用故障设备和线路,防止其影响网络其它部分。
3) 如系线路故障通知各有关方面(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,检查设备故障前的异常日志信息;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认故障。
5. 路由器故障处理
一旦发现到总行7206路由器故障可按以下步骤来处理:
●联系XX公司,并启动原厂商保修服务备件更换程序。
●因为两台7206路由器是互为备份的,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,等待原厂商备件到达。
● 对于能够在线插拔的接口模块、有standby 的引擎和电源,优先使用在线更换方式。在线更换的具体操作流程如下:
a) 用笔记本电脑连接在网络设备的Console 上,启动Console 监控和记录;
b) 准备好存档的系统配置,备用。如有可能,同时保存当前系统配置;
c) 对故障模块上连接的线缆做好标记,小心拔下;
d) 做好安全接地,拔下故障模块;
e) 检查设备和模块状态,确认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,插上更换的备件模块;
g) 检查设备和模块状态,确认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) 检查线缆连接状态正常;
j) 确认备件更换成功。
l 对于机箱、不能在线插拔的接口模块、或者没有standby 的引擎和电源,采用下电更换方式。下电更换的具体操作流程如下:
a) 准备好存档的系统配置,备用。如有可能,同时保存当前系统配置;
b) 准备好原先使用的系统软件,备用;
c) 故障设备下电;
d) 对需要拔除的线缆做好标记,小心拔下。如果机箱或引擎更换,需拔除所有连接线缆;
e) 更换备件;
f) 用笔记本电脑连接在网络设备的Console 上,启动Console 监控和记录;
g) 设备上电;
h) 检查系统自检情况,确认无硬件故障;
i) 安装系统软件;
j) 恢复系统配置;
k) 冷启动,确认软硬件正常工作;
l) 按原样插上其它线缆;
m) 检查线缆连接状态正常;
n) 确认备件更换成功。

三、 核心交换机故障应急
1. 一台4506交换机故障应急
查看日志,检查设备故障前的异常日志信息;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、确认故障。
因为两台4506核心交换机完全是热备的双机,因此一台发生故障并不影响业务运行。对于配置问题要制定正确的更改配置脚本,备份当前配置以后实施更改;对于线路问题的要制作新网线,替换故障的网线;对于硬件问题要练习XX公司,申请硬件故障维修。
对于能够在线插拔的接口模块、有standby 的引擎和电源,优先使用在线更换方式。在线更换的具体操作流程如下:
a) 用笔记本电脑连接在网络设备的Console 上,启动Console 监控和记录;
b) 准备好存档的系统配置,备用。如有可能,同时保存当前系统配置;
c) 对故障模块上连接的线缆做好标记,小心拔下;
d) 做好安全接地,拔下故障模块;
e) 检查设备和模块状态,确认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,插上更换的备件模块;
g) 检查设备和模块状态,确认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) 检查线缆连接状态正常;
j) 确认备件更换成功。
l 对于机箱、不能在线插拔的接口模块、或者没有standby 的引擎和电源,采用下电更换方式。下电更换的具体操作流程如下:
a) 准备好存档的系统配置,备用。如有可能,同时保存当前系统配置;
b) 准备好原先使用的系统软件,备用;
c) 故障设备下电;
d) 对需要拔除的线缆做好标记,小心拔下。如果机箱或引擎更换,需拔除所有连接线缆;
e) 更换备件;
f) 用笔记本电脑连接在网络设备的Console 上,启动Console 监控和记录;
g) 设备上电;
h) 检查系统自检情况,确认无硬件故障;
i) 安装系统软件;
j) 恢复系统配置;
k) 冷启动,确认软硬件正常工作;
l) 对于交换机要将VTP 设置为Client 模式,首先连接上行线缆,确认VTP 复制正确;
m) 按原样插上其它线缆;
n) 检查线缆连接状态正常;
o) 确认备件更换成功。

2. 当核心交换同时瘫痪在20分钟内保证业务正常运作
现有2台备用的cisco3550,在两台核心cisco4506同事瘫痪后,将其作为核心交换来保证业务的正常运作,同时保持原有的网络拓扑及网络核心的安全策略和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、将楼层交换机的fa0/47和48口空出来,并做好相应的配置
实施步骤
第一步:两台3550上架并加电启用(预计3分钟)
第二步:将连接hp小机的光纤接口连到3550上(预计1分钟)

cisco4506备的fa2/4对应3550备的fa0/4
以此类推
cisco4506备的fa2/34对应3550备的fa0/34
第五步:3台楼层交换机与3550之间的互连(预计3分钟)
3550主的fa0/41对应255.15的fa0/47
3550主的fa0/43对应255.16的fa0/47
3550主的fa0/45对应255.17的fa0/47
