思科关闭日志_关于思科交换机的日志配置总结

(以下总结参考了思科 Release 12.2(46)SG版本说明书)

一、日志等级及格式

注：Level 数字越小越严重

格式列举，例如：

*Nov 29 02:18:03.503 GMT: %DHCPD-4-PING_CONFLICT: DHCP address conflict: server pinged 10.39.2.17

*Nov 29 02:18:03.503为日期

%DHCPD-4-PING_CONFLICT为报错的功能模块，4代表level等级

DHCP address conflict: server pinged 10.3

二、Default System Message Logging Configuration

三、配置日志

1、日志进程开关

2、调整日志缓存区大小及远程会话显示日志

eg:

# config ter

# logging buffered [size]

# end

# terminal moniter (只对当前会话窗口有效)

3、同步日志消息

将不请自来的日志信息与当前操作进行区分，不请自来的日志输出完继续进行提示当前操作

config ter

line [console | vty] line-number[ending-line-number

logging synchronous [level [severity-level | all] | limitnumber-of-buffers]

end

4、日志添加本地时间戳及微秒

service timestamps debug datetime msec localtime #debug时间戳

service timestamps log datetime msec localtime #log时间戳

5、定义输出消息的严重级别

config ter

#By default, the console receives debugging messages and numerically lower levels

logging console [level]

#By default, the console receives debugging messages and numerically lower levels

logging monitor [level]

#By default, syslog servers receive informational messages and numerically lower levels

logging trap [level]

end
