== 简介 ==
 +
 
 +
系统日志命令syslog使用设备local0~7从远程服务器和网络设施接收日志记录信息。路由器、交换机、防火墙和负载均衡器都分别使用不同的设备来记录日志，它们都有自己的日志文件，这样可以便于故障排除。下面的例子将会教您怎样为每种设备设置不同的日志记录文件。
 +
 
 +
如果您有一个大的数据中心，可能您会按上述建议停止将所有记录写入/var/log/messages。在下面的所有网络设备配置文件例子中，我们会登录到上一章节已设置好的远程linux登录服务器192.168.1.100。
 +
 
 +
== Cisco 路由器 ==
 +
 
 +
默认设置下，思科路由器使用默认设备local7将日志信息发送到它们的日志服务器。在此例子中不要设置此默认设备，记得设置路由器，使日志内容包含时间戳和loopback接口的源IP地址
 +
 
 +
service timestamps log datetime localtime
 +
no logging console
 +
no logging monitor
 +
logging 192.168.1.100
 +
 
 +
==运行CATOS的Catalyst CAT系列交换机==
 +
 
 +
默认设置下，思科交换机也会通过设备local7将日志信息发送给它们的日志服务器。请不要改变该设置，这样路由器和交换机都会将日志写入同一文件
 +
set logging server enable
 +
set logging server 192.168.1.100
 +
set logging level all 5
 +
set logging server severity 6
 +
 
 +
==Cisco本地导向器 ==
 +
 
 +
本地导向器利用syslog输出命令来设置它们的日志记录设备和严重度。设置值应按格式FF.SS（设施.严重度），使用表IV-1中的数字定义：
 +
===Table IV-1 本地导向器的日志记录设备和严重度的数字定义===

简介

系统日志命令syslog使用设备local0~7从远程服务器和网络设施接收日志记录信息。路由器、交换机、防火墙和负载均衡器都分别使用不同的设备来记录日志，它们都有自己的日志文件，这样可以便于故障排除。下面的例子将会教您怎样为每种设备设置不同的日志记录文件。

如果您有一个大的数据中心，可能您会按上述建议停止将所有记录写入/var/log/messages。在下面的所有网络设备配置文件例子中，我们会登录到上一章节已设置好的远程linux登录服务器192.168.1.100。

Cisco 路由器

默认设置下，思科路由器使用默认设备local7将日志信息发送到它们的日志服务器。在此例子中不要设置此默认设备，记得设置路由器，使日志内容包含时间戳和loopback接口的源IP地址 

service timestamps log datetime localtime
no logging console
no logging monitor
logging 192.168.1.100

运行CATOS的Catalyst CAT系列交换机

默认设置下，思科交换机也会通过设备local7将日志信息发送给它们的日志服务器。请不要改变该设置，这样路由器和交换机都会将日志写入同一文件 

set logging server enable
set logging server 192.168.1.100
set logging level all 5
set logging server severity 6

Cisco本地导向器

本地导向器利用syslog输出命令来设置它们的日志记录设备和严重度。设置值应按格式FF.SS（设施.严重度），使用表IV-1中的数字定义：

Table IV-1 本地导向器的日志记录设备和严重度的数字定义

Facility

FF Value

 

Severity

SS Value

local 0

16

 

System unusable

0

local 1

17

 

Immediate action required

1

local 2

18

 

Critical condition

2

local 3

19

 

Error conditions

3

local 4

20

 

Warning conditions

4

local 5

21

 

Normal but significant conditions

5

local 6

22

 

Informational messages

6

local 7

23

 

Debugging messages

7

这个例子使用设备local4和表IV-1中的日志调试信息。 

syslog output 20.7
no syslog console
syslog host 192.168.1.100

Cisco PIX 防火墙

PIX防火墙使用表IV.2的数字定义来决定它们的日志记录设备。

Table IV-2 PIX防火墙的日志记录设备和严重度的数字定义

Facility

Logging Facility

Command Value

local 0

16

local 1

17

local 2

18

local 3

19

local 4

20

local 5

21

local 6

22

local 7

23

此配置案例中，假设日志服务器连接到“inside”保护接口。它将日志信息发送到local3,严重度为5（通知），这个严重度由logging trap命令设置 

logging on
logging standby
logging timestamp
logging trap notifications
logging facility 19
logging host inside 192.168.1.100

Cisco CSS11000 (Arrowpoints)负载均衡器

配置思科CSS11000系列负载均衡器的方法更直接。 您只需要用logging host命令指定一数字来代表日志设备，然后用logging subsystem命令来设置严重度。此例子中CSS11000的日志设备为local6,严重度为6（信息） 

logging host 192.168.1.100 facility 6
set logging subsystem all info-6
logging commands enable

思科syslog.conf文件示例

#
# All LOCAL6 messages  (debug and above) go to the CSS file ciscocss
